Migraine In Ayurveda
Ayurvedic Perspective of Migraine and its management
Migraine is one of the worst headaches a person can experience. It is described as a throbbing or pulsating pain that can be on one side of the head.It can begin in a specific area and then spread while it builds in intensity. A migraine is associated with nausea and vomiting. The person will also be
sensitive to light, sounds and even certain smells. Sleeping can be difficult and many people become depressed. They can last for a couple of hours or for several days. The symptoms of Migraine almost simulates with the condition “Ardhaavabhedaka “ which is one among the 11 types of Shiro rogas explained
in Ayurvedic classics .Lets discuss about the causative factors, pathology and management of Migraine in Ayurveda.
General Pathology
Vagbhata in the Ashtanga Hridaya explains the causative factors of Shiro ruja (Different types of head aches) as Air pollution, too much exposure of sun, cold, over use of water activities, too much sleeping or less sleep, sweating of head,
stress and related conditions, holding of tear, too much water intake, alcohol over use, infections, blocking natural urges, not being tidy and clean- both internally and externally, reduced oil application on body, use of computer or similar activities where the person has to look downwards for a longer period of time, digestive disturbances, talking on loud voice for longer time etc. Because of these factors, the Doshas are vitiated with the dominance of Vata, reaches head to create the pathological process. There is a migraine "pain centre" or generator in the brain. A migraine begins when hyperactive nerve cells send out impulses to the blood vessels, causing them to clamp down or constrict, followed by dilation (expanding) and the release of
prostaglandins, serotonin, and other inflammatory substances that cause the pulsation to be painful. The hyper action of the nerve cells and expansion and dilation of blood vessels are caused because of the Vata vitiation due to the above factors. This further vitiates Pitta and Kapha Doshas in our body, which
causes the inflammatory process. Charaka also mentioned that if this condition left untreated, it can lead to blindness or deafness.
Management in Ayurveda
Ayurveda has a variety of efficacious procedures and medications with no drawbacks and incidence of recurrence in the treatment of Migraine. Internal preparations, external treatments and Panchakarma (purification) treatments
are adopted for the management. This is done after a detailed diagnosis according to Ayurvedic methods. History of the disease with duration, previous disease history, mental state, pattern of sleep, appetite, food habits, activities, analysing the sense organs, analysing the pulse, character of stool and urine,
menstrual history, etc are examined in detail. This helps to get knowledge regarding the involvement of Dosha and the intensity of the disease. Treatment is done according to these two factors. First phase in the management of Migraine (Ardhavabhedaka) is Nidana Parivarjana (avoiding Triggering factors). Ayurveda enlists various nidanas (Reasons) which includes aharaja (diet born), vihaaraja (lifestyle related), manasika (mind and emotions related) factors. Most of the nidanas mentioned in Ayurveda go in similarity with migraine triggers, which has an active part in the diagnosis as well as in planning the treatment modalities.
Therapies Generally Used.---
External treatments along with the internal preparations are very effective in chronic conditions. Panchakarma helps to remove the accumulated toxins and help to strengthen the nerve system. Involvement of other systemic disorders is also taken into account before deciding the treatment protocols.
1. Thala pothichil : Various kinds of paste (grinded mixture of selected herbs in suitable liquid media ) over the forehead / entire head help for the sudden relief from the ache. The preparations help to normalize the hyper action of the nerve cells and regulates the blood circulation towards the brain
2. Thalam : Special herbal powders suitable to reduce the Dosha vitiation, are selected and mixed with suitable liquid media(oils/ghee) and this medicated herbal paste is applied lukewarm over the crown of head (Anatomically over the Bregma point on skull). (Dur 25-45min).
3. Shiro abhyanga : Head Massaging with Oils suitable for the Dosha vitiation, helps to increase the blood circulation towards brain and also helps to relax the spastic muscles on head. Special care is taken to massage the Marmas or the Vital points on head which have marvelous results.
4. Nasya : Nasya (application of herbal preparations through nostrils) is one of the treatments which directly acts on the nerves and removes the toxins accumulated in the sinuses. Mucus lining inside the nostrils are one of the areas where numerous nerve endings are exposed. The medicated oils applied through Nasya directly acts on these nerve endings and help to pacify Vata Dosha in disturbed nerves and control the abnormal impulses gernerated by these nerves. The special preparations used for Nasya drains the mucus deposited in the sinuses there by the pressure in this area is relieved. The
medicinal contents of the oils administered, stimulate the higher centers of brain which have actions on regulation of endocrine, nervous system and circulatory functions.
5. Shiro dhara : Shiro dhara with Takram (medicated butter milk) is also another important therapy which is used to control the vitiated vata kapha doshas localized head.(Dur 25-75min) Other Panchakarma treatments like Vasti (a course of medicated oil and decoction enemas), Virechana (purgation) also helps to put the toxins out from the body.
After the Panchakarma therapies, special preparations called Rasayana (immuno regulatory) is administered. Rasayana preparations improve the immune system further improving the perception of sense organs. Migraine due to other systemic involvement like psychological problems, digestive problems,
blood pressure, ophthalmic problems, immune problem, improper menstruation, etc will be relieved when treated according to the specific treatment told for these diseases.

Cool Facts About Brain
Dear Friends

On lighter note I m penning down some cool facts about our BRAIN.

THE BRAIN
The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.
1. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.
2. The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
3. The human brain cell can hold 5 times as much information as the Encyclopedia Britannica. Or any other encyclopedia for that matter. Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 or even 1,000 terabytes. The National Archives of Britain, containing over 900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.
4. Your brain uses 20% of the oxygen that enters your bloodstream. The brain only makes up about 2% of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.
5. The brain is much more active at night than during the day.Logically, you would think that all the moving around, complicated calculations and tasks and general interaction we do on a daily basis during our working hours would take a lot more brain power than, say, lying in bed. Turns out, the opposite is true. When you turn off your brain turns on. Scientists don’t yet know why this is but you can thank the hard work of your brain while you sleep for all those pleasant dreams.
6. Scientists say the higher your I.Q. the more you dream. While this may be true, don’t take it as a sign you’re mentally lacking if you can’t recall your dreams. Most of us don’t remember many of our dreams and the average length of most dreams is only 2-3 seconds–barely long enough to register.
7. Neurons continue to grow throughout human life. For years scientists and doctors thought that brain and neural tissue couldn’t grow or regenerate. While it doesn’t act in the same manner as tissues in many other parts of the body, neurons can and do grow throughout your life, adding a whole new dimension to the study of the brain and the illnesses that affect it.
8. Information travels at different speeds within different types of neurons. Not all neurons are the same. There are a few different types within the body and transmission along these different kinds can be as slow as 0.5 meters/sec or as fast as 120 meters/sec.
9. The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain. That doesn’t mean your head can’t hurt. The brain is surrounded by loads of tissues, nerves and blood vessels that are plenty receptive to pain and can give you a pounding headache.
10. 80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on TV. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue. So the next time you’re feeling dehydrated get a drink to keep your brain hydrated.

Best Wishes

Multiple Sclerosis
Introduction
Multiple sclerosis (MS) is a disease affecting nerves in the brain and spinal cord, causing problems with muscle movement, balance and vision.
Each nerve fibre in the brain and spinal cord is surrounded by a layer of protein called myelin, which protects the nerve and helps electrical signals from the brain travel to the rest of the body. In MS, the myelin becomes damaged.
This disrupts the transfer of these nerve signals, causing a wide range of potential symptoms, such as:
Loss of vision – usually only in one eye
Spasticity – muscle stiffness that can lead to uncontrolled muscle movements
Ataxia – difficulties with balance and co-ordination
Fatigue – feeling very tired during the day
Types of multiple sclerosis
Around 8 out of 10 people with MS will have the relapsing remitting type of MS.
Someone with relapsing remitting MS will have periods of time where symptoms are mild or disappear altogether. This is known as remission and can last for days, weeks or sometimes months.
Remission will be followed by a sudden flare-up of symptoms, known as a relapse. Relapses can last from a few weeks to few months.
Usually after around 10 years, around half of people with relapsing remitting MS will go on to develop secondary progressive MS.
In secondary progressive MS, symptoms gradually worsen and there are fewer or no periods of remission.
The least common form of MS is primary progressive MS. In this type, symptoms gradually get worse over time and there are no periods of remission.
Treatment
There is currently no cure for MS but there are a number of treatments that can help.
Relapsing remitting MS and secondary progressive MS can be treated with disease-modifying drugs. These are designed to slow the progression of the disease and reduce the number of relapses. But they are not suitable for all people with MS.
For example at the moment, there is no treatment that can slow the progress of primary progressive MS.
There are also a wide range of treatments, including steroid injections and physiotherapy, that can help relieve symptoms and make day-to-day living easier.
Causes
MS is known as an autoimmune condition. This is where something goes wrong with the immune system (the body’s defence against infection) and it mistakenly attacks healthy body tissue – in this case, the myelin covering of nerves.
This can cause multiple sections of the brain and spinal column to become damaged and hardened (sclerosis), which can disrupt the nerve signals passing through these areas.
Exactly what causes the immune system to act in this way is unclear, but most experts think a combination of genetic and environmental factors are involved.
Who is affected
Symptoms usually first develop between the ages of 15 and 45, with the average age of diagnosis being about 30.
For reasons that are unclear, MS is twice as common in women than men, and more common in white people than black and Asian people
Outlook
MS can be a challenging and frustrating condition to live with but new treatments over the past 20 years have considerably improved the quality of life of people with the disease.
MS is not fatal, but some complications which can arise from more severe MS, such as pneumonia, can be.
As a result, the average life expectancy for people with MS is around 10 years lower than the population at large.
Symptoms of multiple sclerosis
The central nervous system (brain and spinal cord) controls all of your body's actions. When MS damages the nerve fibres that carry messages to and from your brain, symptoms can occur in any part of your body.
There are many different symptoms of MS and they affect each person differently. Some of the most common symptoms include:
Numbness and tingling
Blurring of vision
Problems with mobility and balance
Muscle weakness and tightness
Most people with MS only have a few of these symptoms and it is unlikely someone would develop all possible symptoms.
The symptoms are unpredictable. Some people's MS symptoms develop and increase steadily over time, while for others, they come and go periodically.
Periods when symptoms get worse are known as relapses. Periods when symptoms improve or disappear are known as remissions.
Visual problems
In around one in five cases of MS, the first noticeable symptom is problems with one of your eyes. You may experience:
Some loss of vision in the affected eye – this can range from mild to severe (total loss of vision occurs in 1 in 35 cases)
Colour blindness
Eye pain; usually made worse when moving the eye
Flashes of light when moving the eye
These symptoms are the result of optic neuritis, which is inflammation (swelling) of the optic nerve that transmits visual information to the brain. This normally only affects one eye.
Other visual problems that can occur in MS include:
Double vision
Eye pain in both eyes
Involuntary eye movements (usually from side to side), known as nystagmus
Abnormal sensations
Abnormal sensations can also be a common initial symptom of MS. This can take the form of numbness or tingling in different parts of your body.
Muscles in your arms and legs may also feel unusually weak.
Muscle spasms and spasticity
MS can damage nerve fibres in your brain and spinal cord, which can cause muscles to contract tightly and painfully (spasm). Your muscles may also become stiff and resistant to movement, which is known as spasticity.
Pain
Around half of people with MS experience pain, which can take two forms:
Neuropathic pain – caused by damage to the nerve fibres in the brain and spinal cord. It can be a stabbing pain, extreme skin sensitivity, or a burning sensation.
Musculoskeletal pain – this is not caused directly by MS, but can occur if there is excess pressure on muscles or joints as a result of spasms and spasticity.
Mobility problems
MS can affect balance and co-ordination. It can make walking and moving around difficult, particularly if you also have muscle weakness and spasticity. You may experience:
Ataxia – difficulty with co-ordination
Tremor – shaking of the limbs, which is rare, but can be severe
Dizziness and vertigo can happen late on and can make you feel as if your surroundings are spinning
Extreme tiredness (fatigue)
Feeling extremely tired (fatigue) is a common symptom of MS that many people describe as one of the most troublesome.
It is estimated as many as 9 out of 10 people with MS will experience episodes of fatigue.
People with MS have reported feeling an overwhelming sense of weariness where even the most simple physical or mental activity seems to be a tremendous struggle to carry out.
Fatigue may be worse in hot weather, after exercising, or during illness.
Problems with thinking, learning and planning
Around half of people with MS have problems with thinking, learning and planning (known as cognitive dysfunction) in the early stages of the disease. They may experience:
Problems understanding and using language
A shortened attention span
Problems learning and remembering new things (long-term memory is usually unaffected)
Problems understanding and processing visual information, such as reading a map
Difficulty with planning and problem solving – people often report that they know what they want to do, but can’t grasp the method of how to do it
Problems with reasoning, such as mathematical laws or solving puzzles
Mental health issues
Around half of all people with MS experience at least one episode of depression at some point in their life.
It is unclear whether the depression arises from the damage to the brain caused by MS, or due to the stress of having to live with a long-term condition, or both.
Anxiety can also be a problem for people with MS, especially during the start of a relapse, as they are naturally anxious about the return of their symptoms.
Some people with MS can sometimes experience rapid and severe mood swings, suddenly bursting into tears, laughing or shouting angrily for no apparent reason.
Sexuality
Many people with MS lose interest in sex.
Men with MS often find it hard to obtain or maintain an erection (erectile dysfunction). They may also find it takes a lot longer to ejaculate when having sex or masturbating, and may even lose the ability to ejaculate altogether.
Women may find it more difficult to achieve orgasm.
Bladder problems
Bladder problems are common in MS.
These may include:
Difficulty emptying the bladder completely
Having to urinate more frequently
Having a sudden, urgent need to urinate which can lead to unintentionally passing urine (urge incontinence)
Having to get up frequently during the night to pass urine (nocturia)
Constipation
Constipation affects around half of people with MS. They may pass stools much less frequently than normal, and find this difficult.
Severe constipation can lead to faecal impaction, where a large, solid stool becomes stuck in the back passage (rectum) and begins to stretch the muscles of the rectum, weakening them. This can cause loss of normal bowel control (bowel incontinence), where watery stools leak out.
Causes of multiple sclerosis
Multiple sclerosis (MS) occurs because of damage to the nerve fibres of the central nervous system. Your central nervous system consists of the brain and spinal cord and is responsible for controlling every action, conscious and unconscious, of your body.
Myelin
When you perform an action, your brain sends messages to the appropriate part of your body through the nerve fibres in your spinal cord. These nerve fibres are covered by a substance called myelin. Myelin insulates the nerve fibres and helps carry messages to and from your brain quickly and smoothly. In MS, the myelin around your nerve fibres becomes damaged. This disturbs the messages coming to and from your brain.
Autoimmune condition
MS is an autoimmune condition. This means your immune system mistakes the myelin for a foreign substance and attacks it. The myelin becomes inflamed in small patches (called plaques or lesions), which can be seen on an MRI scan. This process is called demyelination.
Demyelination disrupts the messages travelling along nerve fibres. It can slow them down, jumble them, accidentally send them down a different nerve fibre, or stop them from getting through completely.
When the inflammation goes away, it can leave behind scarring of the myelin sheath (known as sclerosis) and sometimes damage to the underlying nerve cell.
Why do people develop multiple sclerosis?
It is not understood what causes the immune system to attack myelin, although there are several theories. Most experts agree that MS is probably caused by a combination of genetic and environmental factors. This means it's partly due to genes you inherit from your parents and partly due to outside factors that may trigger the condition.
Genetic factors
MS is not defined as a genetic condition because there is no single gene that causes it. It's not directly inherited, although research has shown people who are related to someone with MS are more likely to develop it.
Researchers have found that if one twin develops MS then the second twin has around a one in four chance of also developing MS.
The chances of a brother, sister, or child of a person with MS also developing MS themselves is less than 1 in 30.
It's possible that different combinations of genes make developing MS more likely, and research into this is continuing. However, genetic theories cannot explain the wide variation in occurrences of MS throughout the world.
Sunlight and vitamin D
Research into MS around the world has shown that it's more likely to occur in countries far from the equator. For example, MS is relatively common in the UK, North America and Scandinavia, but rare in Malaysia or Ecuador.
It’s possible that people living further from the equator are exposed to less sunlight and, therefore, have less vitamin D in their bodies. Some studies have found a link between lower levels of vitamin D and incidence of MS.
Some researchers have suggested that vitamin D supplements may reduce the risk of MS. However, this has not been proven.
Viral infection
Another theory is that MS may be the result of viral infection of the nervous system and /or the immune system.
The idea is that the virus lies dormant for many years and then periodically ‘re-awakens’, triggering an autoimmune response against the nervous system.
This could explain the relapse-remission nature of most cases of MS.
A virus called the Epstein-Barr virus (EBV) is known to act in this way, but there is currently no firm evidence that EBV, or any other virus, is responsible for MS.
Problems with blood flow
A new and controversial theory is that some cases of MS may actually be due to problems with the flow of blood inside the body.
The idea is that some people may have narrowing of veins inside their brain and spinal cord and the blood supply from the brain and spine has trouble returning to the heart (known as cerebrospinal venous insufficiency).
This could lead to a build-up of tiny iron deposits inside nerve tissue, which may damage the nerves and /or trigger an immune response.
Some studies have found higher-than-expected levels of cerebrospinal venous insufficiency in people with MS, but others have not.
Further research is ongoing looking at larger groups of people and using more sophisticated brain imaging scanning.
Diagnosing multiple sclerosis
If you have unexplained symptoms that are similar to those of multiple sclerosis (MS), see Dr. B C Shah. If Dr. B C Shah suspects MS, they will ask you for a detailed medical history, including past signs and symptoms as well as the current state of your health.
Dr. B C Shah can refer you to a neurologist (a specialist in conditions of the central nervous system).
If Dr. B C Shah suspects MS, you should see a neurologist within six weeks.
Diagnostic tests
Diagnosing MS is complicated because no single laboratory test can positively diagnose it.
Several conditions have symptoms similar to those of MS, so your neurologist may rule them out first.
It may also not be possible to confirm a diagnosis if you have had only one ‘attack’ of MS-like symptoms. A diagnosis can usually only be made with confidence once a person has a relapse (return of symptoms).
To confirm MS, your neurologist may carry out a number of tests.
Neurological examination
Your neurologist will look for changes or weakness in your eye movements, leg or hand co-ordination, balance, speech and reflexes. This will show whether your nerve pathways are damaged.
Magnetic resonance imaging (MRI) scan
An MRI scan creates a detailed image of your brain and spinal cord.
MRI scans can show whether there is any damage or scarring of the myelin in your central nervous system. Over 9 out of 10 people with MS are diagnosed using an MRI scan.
The procedure is painless and usually takes between 10 and 30 minutes. A standard MRI scanner is like a giant tube or tunnel. You may feel claustrophobic when going into the tunnel and the machine is noisy.
Tell your neurologist if you have any concerns about this experience.
Evoked potentials test
An evoked potentials test involves placing small electrodes on your head. These monitor how your brain waves respond to what you see and hear. It is painless and can show whether it takes your brain longer than normal to receive messages.
Lumbar puncture
A lumbar puncture is also sometimes called a spinal tap. A sample of your cerebrospinal fluid (the fluid that surrounds your brain and spinal cord) is taken using a needle inserted into the area around your spinal cord.
This is done under local anaesthetic, which means that you will be awake but the area that the needle goes into will be numbed. The sample is tested for antibodies, the presence of which means that your immune system has been fighting a disease in your central nervous system.
A lumbar puncture is usually only needed if other tests for MS are inconclusive.
Blood tests
Blood tests are usually performed to rule out other causes of your symptoms, such as vitamin deficiencies. In addition, antibody tests may be required, for example to rule out a special type of MS called Devic's disease.
Diagnosing the different types of multiple sclerosis
Once a diagnosis of MS has been made, your neurologist may be able to identify which type of MS you have.
However, this often only becomes clear over time as the symptoms of MS are so varied and unpredictable.
A diagnosis of relapsing remitting multiple sclerosis (RRMS) may be made if:
You have two relapses of your symptoms more than 30 days apart
You have one relapse and an MRI scan shows new myelin damage or scarring three months later
A diagnosis of secondary progressive multiple sclerosis (SPMS) may be made if:
You have had relapses of your symptoms in the past
You have become steadily more disabled for at least six months, with or without relapses
A diagnosis of primary progressive multiple sclerosis (PPMS) may be made if you have had no previous relapses of your symptoms, and:
You have become steadily more disabled for at least one year
An MRI scan shows damage and scarring to myelin
a lumbar puncture shows antibodies in the fluid surrounding your brain and spinal cord
Treating multiple sclerosis
Multiple sclerosis (MS) is a complex disorder that can impact on many aspects of your life so you will need to receive treatments from Dr. B C Shah and his team working together.
Members of your care team may include:
A neurologist (a specialist in treating conditions that affect the nervous system)
A physiotherapist
A speech and language therapist
An occupational therapist
An incontinence adviser
A psychologist
A pharmacist
A specialist MS nurse who will often serve as a point of contact
Living with multiple sclerosis
A diagnosis of MS is life changing. You may need long-term treatment to control your symptoms and you may have to adapt your daily life.
Self-care
Self-care is an integral part of daily life. It means you take responsibility for your own health and wellbeing, with support from people involved in your care. Self-care includes the things you do each day to stay fit, maintain good physical and mental health, prevent illness or accidents, and effectively deal with minor ailments and long-term conditions. People living with long-term conditions can benefit enormously if they receive support for self-care. They can live longer, have less pain, anxiety, depression and fatigue, have a better quality of life, and be more active and independent.
Regular reviews
Because MS is a long-term condition, you'll be in regular contact with your healthcare team. A good relationship with the team means you can easily discuss your symptoms or concerns. The more the team knows, the more they can help you.
Keeping well
Everyone with a long-term condition such as MS is encouraged to get a flu jab each autumn to protect against flu (influenza). It's also recommended that they get an anti-pneumoccocal vaccination. This is a one-off injection that protects against a specific serious chest infection called pneumococcal pneumonia.
Healthy eating and exercise
Regular exercise and a healthy diet are recommended for everyone, not just people with MS. They help prevent many conditions, including heart disease and many forms of cancer. Try to eat a balanced diet, containing all the food groups, to give your body the nutrition it needs. Exercising regularly can help relieve stress and reduce fatigue.

Hydrocephalus
Hydrocephalus is a build-up of fluid on the brain. The excess fluid puts pressure on the brain, which can cause it to be damaged.
The damage to the brain can result in a wide range of symptoms, including:
Headache
Being sick
Blurred vision
Difficulty walking
Hydrocephalus can usually be treated using a piece of equipment known as a shunt. A shunt is a thin tube that's surgically implanted in the brain and used to drain away the excess fluid.
Cerebrospinal fluid
In the past, hydrocephalus was often referred to as ‘water on the brain’. However, this term is incorrect because the brain is not surrounded by water but by a special fluid called cerebrospinal fluid (CSF).
Cerebrospinal fluid has three important functions:
It protects the brain from damage
It removes waste products from the brain
It provides the brain with the nutrients it needs to function properly
The brain constantly produces new cerebrospinal fluid (about a pint a day), while old fluid is released from the brain and absorbed into the blood vessels. However, if this process is interrupted, the level of CSF can quickly build-up, placing pressure on the brain.
Types of hydrocephalus
There are three main types of hydrocephalus:
Hydrocephalus that's present at birth (congenital hydrocephalus)
Hydrocephalus that develops after birth (acquired hydrocephalus)
Hydrocephalus that usually only develops in older people (normal pressure hydrocephalus or NPH)
These are briefly described below.
Congenital hydrocephalus
Congenital hydrocephalus is present in babies when they're born and can be caused by birth defects, such as spina bifida, or as a result of an infection that the mother develops during pregnancy, such as mumps or rubella (German measles).
Congenital hydrocephalus carries the risk of long-term mental and physical disabilities as a result of permanent brain damage.
Acquired hydrocephalus
Acquired hydrocephalus can affect children or adults. It usually develops after an injury or illness. For example, it may occur after a serious head injury or as a complication of a medical condition, such as a brain tumour.
Normal pressure hydrocephalus
Normal pressure hydrocephalus (NPH) is a poorly understood condition that usually only affects people over 50 years old.
It can sometimes develop after an injury or a stroke, but in most cases the cause is unknown.
The average age of people with NPH is 75, although it's a rare condition.
Symptoms of hydrocephalus
Hydrocephalus (fluid on the brain) causes slightly different symptoms depending on the type of hydrocephalus and the age of the person affected.
Congenital hydrocephalus
Babies with hydrocephalus at birth (congenital hydrocephalus) often have distinctive physical characteristics. Physical signs include:
Your baby’s head may appear unusually large
Your baby’s scalp may be thin and shiny with easily visible veins
Your baby may have a bulging or tense fontanelle (the soft spot on the top of their head)
Your baby's eyes appear to be looking down; this is known as the ‘setting-sun sign’ because the eyes resemble the sun setting below the horizon
The muscles in your baby’s lower limbs may appear stiff and be prone to muscle spasms (contractions)
As well as these physical signs, congenital hydrocephalus can also cause symptoms such as:
Poor feeding
Irritability
Being sick
Drowsiness
Acquired hydrocephalus
Hydrocephalus that develops in adults or children (acquired hydrocephalus) can cause headaches. The headache may be worse in the morning after waking up, as the fluid in your brain doesn't drain so well while you're lying down and may have built up overnight. Sitting up for a while may improve your headache. However, as the condition progresses, the headaches may become continuous. If hydrocephalus is not treated, it can be life-threatening.
Other symptoms of acquired hydrocephalus include:
Neck pain
Feeling sick
Being sick – which may be worse in the morning
Drowsiness, which can progress to a coma
Changes in your mental state, such as confusion
Blurred vision or double vision
Difficulty walking
Not being able to control your bladder (urinary incontinence) and, in some cases, your bowel (bowel incontinence)
Normal pressure hydrocephalus
Unlike the other two types of hydrocephalus, the symptoms of hydrocephalus that develop in older people (normal pressure hydrocephalus or NPH) usually develop slowly, over the course of many months or years.
There are three sets of distinctive symptoms. They affect:
How you walk
Your urinary system
Your mental abilities
These are discussed below.
How you walk
Usually, the first noticeable symptom of normal pressure hydrocephalus (NPH) is a change in how you walk (your gait). You may find it increasingly difficult to take the first step when you want to start walking. Some people have described it as feeling as though they're frozen to the spot. You may also shuffle rather than take proper steps.
As the condition progresses, you may become increasingly unsteady on your feet. You may be more likely to fall, particularly when turning.
Urinary symptoms
The change in the way that you walk is often followed by bouts of urinary incontinence, which may include symptoms such as:
A frequent need to urinate
An urgent need to urinate
Loss of bladder control
Mental abilities
The normal thinking process also starts to slow down. This can take the form of:
Being slow to respond to questions
Reacting slowly to situations
Being slow to process information
These may be confused with the symptoms of dementia. You may actually have mild dementia, which will improve when the normal pressure hydrocephalus (NPH) is treated.
Causes of hydrocephalus
To understand the causes of hydrocephalus (fluid on the brain), it is first useful to understand how cerebrospinal fluid (CSF) circulates through the brain.
Cerebrospinal fluid and the brain
Cerebrospinal fluid (CSF) is created in the brain. It flows through the brain through a series of chambers called ventricles.
Excess cerebrospinal fluid moves out of the brain, where it's absorbed back into the bloodstream by a specialised tissue called the arachnoid villi. The arachnoid villi act like a one-way valve. They allow excess cerebrospinal fluid to leave the brain and filter into blood vessels while preventing the blood from leaking into the brain and damaging it.
Hydrocephalus can develop if:
There's a blockage in one of the ventricles so that excess fluid can't move out of the brain
There's a problem with the arachnoid villi so that fluid is unable to filter into the blood vessels
The brain starts to produce too much cerebrospinal fluid (this is very rare)
Congenital hydrocephalus
Congenital hydrocephalus, where a baby is born with the condition, may be the result of a brain defect that restricts the flow of cerebrospinal fluid. For example, the passages that connect the ventricles in the brain become blocked or narrowed.
These defects in the development of the brain can be caused by health conditions known to cause birth defects. For example, most children born with the most serious type of spina bifida will develop hydrocephalus.
Congenital hydrocephalus can also occur in babies born prematurely (before week 37 of the pregnancy). Some premature babies experience bleeding in their brain, which can block the flow of cerebrospinal fluid and cause hydrocephalus.
Other possible causes of congenital hydrocephalus include:
X-linked hydrocephalus – where the condition occurs as a result of a mutation (change in the genetic material) of the X chromosome
Rare genetic disorders, such as Dandy Walker malformation
Rrachnoid cysts – fluid filled sacs located between the brain or spinal cord and the arachnoid membrane, which is one of the three membranes surrounding the brain and spinal cord
In many cases of congenital hydrocephalus, the cause is unknown. This is medically referred to as idiopathic.
Acquired hydrocephalus
Hydrocephalus that develops in adults or children (acquired hydrocephalus) is usually the result of an injury or illness that causes a blockage between the ventricles of the brain.
Possible causes of acquired hydrocephalus include:
Bleeding inside the brain – for example, if blood leaks out of blood vessels over the surface of the brain (subarachnoid haemorrhage)
Blood clots inside the blood vessels in the brain (venous thrombosis)
Meningitis – an infection of the protective membranes that surround the brain and spinal cord
Brain tumours
Head injury
It's also possible for someone to be born with narrowed passageways in their brain that restrict the flow of cerebrospinal fluid, but don't cause any symptoms until years later.
Normal pressure hydrocephalus
Hydrocephalus that develops in older people (normal pressure hydrocephalus or NPH) can occur after a brain injury, bleeding in the brain or infection. However, in most cases, there's no clear reason why the condition occurs.
There are several theories to explain what happens to the brain in cases of NPH. Some are outlined below.
Problems with the arachnoid villi
One idea is that NPH occurs when something goes wrong with the arachnoid villi, which is the layer of tissue that allows cerebrospinal fluid to filter into the blood vessels. This means that the blood vessels don't reabsorb the fluid. This creates a gradual increase in pressure, which can cause progressive brain damage.
Underlying health conditions
NPH may be caused by underlying health conditions that affect the normal flow of blood. For example, diabetes, heart disease or having a high level of cholesterol in the blood.
The exact cause is unknown, but conditions that affect blood vessels within the brain or that supply blood to the brain (cerebrovascular disease) may be linked to NPH
Diagnosing hydrocephalus
The different types of hydrocephalus (fluid on the brain) can be diagnosed with brain scans.
Congenital hydrocephalus
In some cases, an ultrasound scan can detect congenital hydrocephalus before your baby is born. An ultrasound scan uses high-frequency sound waves to create an image of your womb and the baby inside.
If your baby has some of the physical characteristics associated with congenital hydrocephalus after they're born, such as an enlarged head, they may be referred for an ultrasound scan. If the results of the ultrasound are inconclusive, further testing can be carried out using:
A computerised tomography (CT) scan – this takes a series of X-rays at slightly different angles and uses a computer to put the images together
A magnetic resonance imaging (MRI) scan – this uses a strong magnetic field and radio waves to produce detailed images of the brain
These scans can examine the brain in greater detail. As well as showing the build-up of fluid on the brain and the increased pressure, the scans can also highlight any defects in the structure of the brain that may be causing the hydrocephalus.
Acquired hydrocephalus
Hydrocephalus that develops in adults or children (acquired hydrocephalus) can be diagnosed using a combination of CT and MRI scans. The scans can also reveal any possible causes of your symptoms, such as a brain tumour.
Normal pressure hydrocephalus
Hydrocephalus that usually develops in older people (normal pressure hydrocephalus or NPH) can be difficult to diagnose for the following reasons:
The symptoms come on very gradually
The symptoms are more common to conditions, such as Alzheimer's disease, which may frequently occur with NPH
It's important to make a correct diagnosis because, unlike Alzheimer’s disease, it's possible to relieve the symptoms of NPH using appropriate treatment.
Healthcare professionals have therefore devised a diagnostic checklist. There are four main factors that the checklist examines:
How you walk (your gait)
Your mental ability
Symptoms that affect your bladder control such as urinary incontinence
The appearance of your brain during CT, MRI and ultrasound scans
You may be diagnosed with NPH if you have the combination of an impaired gait, slowing of the normal mental processes and urinary incontinence, and scans have shown that your cerebrospinal fluid (CSF) is at a higher level than usual. CSF is the fluid that surrounds your brain and spinal cord.
However, you may not have all of the symptoms in the checklist.
Further tests may also be carried out to decide whether you would benefit from having surgery, such as:
A lumbar puncture
A lumbar drainage test
A lumbar infusion test
These procedures are briefly described below.
Lumbar puncture
A lumbar puncture, also known as a spinal tap, is a procedure that's used to take a sample of CSF from your lower back.
A hollow needle is inserted between your back bones (vertebrae), and a small amount of the fluid is removed. The pressure of the CSF sample can then be checked.
Removing some CSF during a lumbar puncture may help to improve your symptoms. If this is the case, it's a good indication that you may benefit from treatment with surgery.
Lumbar drain
If having a lumbar puncture doesn't improve your symptoms, this doesn't mean that you do not have NPH. If the lumbar puncture test is negative, you may have a lumbar drain.
A lumbar drain involves inserting a tube between your back bones to drain a large amount of CSF. This is done over a few days to see if this improves your symptoms, such as your ability to walk around. This is usually done under local anaesthetic to numb the area, or sedation to relax you.
Lumbar infusion test
A lumbar infusion test can also be used to help diagnose NPH and decide whether you need surgery. The procedure should be carried out under local anaesthetic so it shouldn't be painful.
The test involves slowly injecting fluid into your lower back while measuring the pressure. The additional fluid should be absorbed by your body so that the pressure stays low. However, if your body can't absorb the extra fluid, the pressure will rise. This could indicate that you have NPH and that surgery will be beneficial. l be beneficial.
Treating hydrocephalus
Hydrocephalus (fluid on the brain) is treated with surgery.
Congenital and acquired hydrocephalus
Babies who are born with hydrocephalus (congenital hydrocephalus) and adults or children who develop hydrocephalus (acquired hydrocephalus) usually require prompt treatment to reduce the pressure on their brain. If the hydrocephalus is not treated, the rise in pressure will damage the brain.
Both congenital and acquired hydrocephalus will be treated with either shunt surgery or neuroendoscopy (see below).
Normal pressure hydrocephalus
Hydrocephalus that usually develops in older people (normal pressure hydrocephalus or NPH) can also be treated with a shunt. However, experience has shown that not everyone with NPH will benefit from shunt surgery.
Due to the risks of complications occurring as a result of surgery, you will need tests to assess whether the potential benefits of surgery outweigh the risks. A lumbar drainage test or lumbar infusion test, or both, can be used to find out whether shunt surgery will benefit you. See Hydrocephalus – diagnosis for more information about these tests.
Shunt surgery will be recommended if testing reveals that it would be beneficial.
Shunt surgery
Shunt surgery involves implanting a thin tube, called a shunt, in the brain. The excess cerebrospinal fluid (CSF) in the brain runs through the shunt to another part of the body, usually the abdomen. From here the fluid is absorbed into your blood stream. The shunt has a valve inside it to control the flow of CSF and to ensure it does not drain too quickly. You can feel the valve as a lump under the skin of your scalp.
The operation
Shunt surgery is carried out by a neurosurgeon (a specialist in surgery of the brain and nervous system). You will be given a general anaesthetic before the operation so that you will be asleep throughout the procedure, which usually takes one to two hours.
After the operation, you may need to spend a few days in hospital to recover. If you have stitches in the wound in your head, they may dissolve on their own, or you may be advised about when these will be removed. Some surgeons use skin staples to close the wound. Like stitches, these will need to be removed after a few days.
Once the shunt has been installed, further treatment for hydrocephalus may be required if the shunt becomes blocked or infected. Shunt repair surgery will then be necessary.
Endoscopic third ventriculostomy (ETV)
An alternative procedure toshunt surgery is an endoscopic third ventriculostomy (ETV). This procedure involves making a hole in the floor of the brain, allowing the trapped CSF to escape to the surface of the brain where it can be absorbed, instead of inserting a shunt.
An ETV is not suitable for everyone. However, it could be a possible treatment option if the build-up of CSF in your brain is the result of a blockage (obstructive hydrocephalus). The CSF will be able to drain through the hole, avoiding the blockage.
During an ETV, a small hole is made in your skull and your neurosurgeon will use an endoscope to look inside the chambers of your brain. An endoscope is a thin, long tube that has a light and a video camera at one end. A small hole will be made inside your brain with the help of the endoscope. After the endoscope has been removed, the wound will be closed using stitches. The procedure takes around one hour.
There is less risk of an infection developing after an ETV than with shunt surgery. However, as with all surgical procedures, there are some risks associated with ventriculostomy.
The long-term results for treatment with ETV are very similar to those for a shunt operation. As with shunts, ETVs may block months or years after surgery, resulting in your symptoms reocurring.
Complications of hydrocephalus
Hydrocephalus (fluid on the brain) can cause some complications, or complications may develop as a result of the surgery used to treat it.
Shunt malfunction
A shunt is a delicate piece of equipment that's prone to malfunction, usually through blockage or infection. It's estimated that up to 4 out of 10 shunts will malfunction in the first year after surgery. Sometimes a scan carried out after the operation shows that the shunt isn't in the best position, and that further surgery may be needed to reposition it.
If a baby or child has a shunt fitted, the shunt may become too small as your child grows, and it will need to be replaced. As most people need to have a shunt for the rest of their life, more than one replacement may be needed.
It's estimated that most children with hydrocephalus may have an average of two procedures for shunt problems before they're 10 years old.
Occasionally, when shunt tubes are positioned, bleeding can occur. This can result in nerve problems, such as weakness down one side. There's also a small risk of seizures (fits) following any surgery on the brain.
In younger children, particularly babies, cerebrospinal fluid (CSF) can run alongside the shunt rather than down it, and it can leak through the skin wound. If this occurs, further stitches will be needed to stop the leak.
Shunt blockage
A shunt blockage can be very serious because it can lead to an excess build-up of fluid on the brain, which can cause brain damage. This will cause the same symptoms of hydrocephalus, such as:
Headaches
Feeling sick
Being sick
Confusion
Drowsiness or coma
In babies, you may notice their head growing larger or they may have a bulging or tense fontanelle (the soft spot on the top of their head).
Contact Dr. B C Shah immediately if you or your child have these symptoms. Emergency surgery will be required to replace the malfunctioning shunt.
Shunt infection
Shunt infection is also a relatively common complication. The risk of infection can be around 3-15% and is more likely to occur during the first few months after surgery.
The symptoms of a shunt infection may include:
Redness and tenderness along the line of the shunt
A high temperature (fever) of 38ºC (100.4ºF) or over
Headache
Being sick
Neck stiffness
Tummy pain (if the shunt drains into your tummy)
Irritability or drowsiness in babies
Contact Dr. B C Shah immediately if you or your child has these symptoms. You may need to have a course of antibiotics to treat the infection and, in some cases, surgery may be required to replace the shunt.
Complications of endoscopic third ventriculostomy (ETV)
An endoscopic third ventriculostomy (ETV) is a surgical procedure where a small hole is made in the floor of your brain. Complications can occur after this type of surgery, such as:
The hole can close
Your brain may not be able to absorb the cerebrospinal fluid that's now draining through it
You may develop an infection, although this is less likely than after shunt surgery
You may have bleeding inside your brain (this is usually minor)
If there's a problem with the hole, it may be possible to repeat the procedure, or you may need to have a shunt fitted.
Other risks of ETV include nerve problems, such as weakness down one side of the body, double vision or hormone imbalances. Most nerve problems will get better, but there's a small risk of permanent problems. There's also a small risk of epilepsy, and a very small risk of an injury to one of the blood vessels in the brain, which may be fatal.
Long-term complications of congenital hydrocephalus
Many babies born with hydrocephalus (congenital hydrocephalus) have permanent brain damage. This can cause a number of long-term complications, such as:
Learning disabilities
Impaired speech
Memory problems
Short attention span
Problems with organisational skills
Vision problems, such as a squint and visual impairment
Problems with physical co-ordination
Epilepsy

EEG
What is an EEG?

An EEG (electroencephalogram) is a test that records the electrical activity of your child's brain. (The nerve cells in your child's brain work by carrying tiny electrical charges.)
When is it used?

An EEG can help your child's healthcare provider diagnose medical problems such as:
epilepsy
sleep apnea or other sleep problems
encephalitis (infection in the brain)
brain tumors

An EEG can help healthcare providers decide on the best medicine to treat epilepsy. This test is sometimes used during surgery to check the effect of anesthesia. It may be used to test for brain death in cases of severe injury or illness.
How do I prepare for an EEG?

Your child's head doesn't need to be shaved for an EEG. Some EEG labs ask that your child's hair be clean and free of hair products such as hairspray or mousse. On the day of the EEG, your child should not have any drinks that containe caffeine (such as sodas, sports drinks, or tea).

Ask your child's provider if there are any special instructions your child needs to follow. Also ask if there are any substances or medicines that your child should avoid before the test.

Sometimes a sedative is given just before the test to help your child relax during the EEG.
What happens during the test?

An EEG normally takes 45 to 60 minutes. During the test your child will relax in a bed. Small metal plates (electrodes) are pasted or taped to your child's head. The electrodes send information to a machine that records brain waves on paper. Young children do not like the feel of the electrodes, but it doesn't hurt except when the electrodes are removed.

EEGs may be done while your child is:
sleeping (Your child may be given a medicine to help your child sleep).
resting with eyes closed (for babies, this may be done by placing a hand over the baby's eyes and playing peek-a-boo)
resting with eyes open
breathing rapidly (and just after)
looking at a flashing light.

The EEG records how the brain responds to these changes. Your child may have a video EEG instead. This gives more time to study the brain waves. A video EEG may take 6 to 8 hours, or be done for 24 hours.
What happens after the test?

Your child can usually go home as soon as the test is done.
What are the benefits and risks of this test?

This test helps your child's healthcare provider diagnose certain medical conditions. There are no risks.
When should I call my child's healthcare provider?

Call your child's provider right away if your child has any change or worsening of symptoms after the test.

What is a seizure?

A seizure is a symptom, not a disease. It happens when nerve cells in the brain don’t work right and there is a sudden abnormal electrical signal in the brain. The seizure can cause strange sensations and behavior. Sometimes it causes muscle spasms and a change in or loss of consciousness.

The 2 most common types of seizures are:
focal or partial seizures, which begin in just a part of the brain but sometimes may spread to involve all of the brain
generalized seizures , which seem to involve all areas of the brain from the start of the seizure.

A common feature of partial seizures is the sensing of something that others are not aware of. For example, you may see flashing lights, have a particular taste in your mouth, or hear noises not seen or heard by others. Sometimes partial seizures also cause some numbness or jerking of the limbs. You may be awake and remember what happened, or you may lose consciousness for a short time.

There are 2 types of generalized seizures based on the pattern of the attack:
A grand mal seizure is a seizure that starts with a loss of consciousness and falling down, followed by a brief period of rigid muscles and a 1- to 2-minute period of violent, rhythmic jerking. The seizure ends with a few minutes of deep sleep before you are conscious again. You will probably not remember the seizure. You may be drowsy for hours after the seizure.
An absence or petit mal seizure is a short period of staring, fluttering eyelids, or twitching of muscles in your face. You do not lose consciousness. You are awake, but you are not able to understand what is going on around you. It’s not possible to pay attention at work or school when you are having petit mal seizures. You will probably not remember the seizure. Petit mal seizures usually begin when you are a child. Each seizure may last only 10 to 30 seconds, but hundreds may happen each day.

One seizure right after another or one very long seizure is called status epilepticus. The symptoms are usually those of a grand mal seizure. This can be life threatening because it can keep you from getting enough oxygen. It is a medical emergency.

If you have had several seizures and no cause can be found that can be corrected with treatment, your healthcare provider may diagnose seizure disorder, which is also called epilepsy.
How does it occur?

Seizures can happen for many different reasons, but most seizures have no known cause.

Seizures can be a symptom of many diseases and conditions, including:
head injury
brain injury at birth
brain infections such as meningitis or encephalitis
brain tumor
stroke
drug and alcohol abuse
withdrawal from alcohol and drugs such as narcotics, cocaine, tranquilizers, and sleeping pills
metabolic imbalances, such as low blood sugar or low blood sodium.
What are the symptoms?

Symptoms of a seizure can include:
aura, a peculiar sensation that occurs just before a seizure and may give you warning that a seizure is about to happen (for example, you may see flashing lights or hear noises)
rapid eye blinking or staring
twitching of the face
smacking of the lips
shaking or jerking of the arms and legs
stiffening of the body
crying or moaning
hallucinations, which may be visual or involve other senses such as hearing, touch, or taste
intense feelings of fear or déjà vu (the feeling that what you are experiencing has happened before even though you know it hasn’t)
loss of consciousness
loss of control of your bladder muscles so that you wet yourself
loss of bowel control
falling suddenly for no clear reason
not responding to noise or words for brief periods
appearing confused or in a haze
nodding the head
breathing problems from choking on food or saliva
vomiting.

You may be drowsy for several minutes after the seizure.
How is it diagnosed?

Your healthcare provider will examine you and take your medical history. You may have blood tests and one or more of the following safe and painless tests or scans to look for possible causes of your seizures:
EEG, which measures electrical activity in the brain
MRI (magnetic resonance imaging) scan, which uses magnetism, radio waves, and a computer to produce a picture of the inside of your head
CT (computed tomography) scan, in which X-rays are taken of your brain at different angles and then combined by a computer.
How is it treated?

The treatment for seizures depends on the cause. If you have a medical problem that is causing the seizures, such as diabetes, you will be treated for that problem.

Your healthcare provider may prescribe an anticonvulsant drug. This medicine will help prevent seizures. Your healthcare provider will adjust the dosage to minimize any side effects from the drug. If you keep having seizures while you are taking medicine, your healthcare provider will:
Check the level of the medicine in your blood.
Make sure you are taking your medicine as prescribed.
Make sure you aren’t drinking alcohol or using illegal street drugs.
Check to see if you are taking other medicines that may interfere with the anticonvulsant.

Medicine is the main treatment for seizures, but several new treatments are being evaluated. These include:
surgery on the area of the brain where the seizures occur
stimulation of a nerve in the neck by a device placed under the skin.
How long will the effects last?

It is not possible to know how long seizures will be a problem for any one person. Absence seizures often stop by the time you are an adult. You may keep having other types of seizures. Depending on the type of seizures you have and how often you have them, after a time your healthcare provider may recommend that you try to slowly decrease your medicines. You usually need to have not had any seizures while on medicine for at least 3 years before this is even considered. During this time it is very important to avoid driving a car or other activities where your life or the lives of others might be in danger if you had a seizure. Never stop taking your medicine without first checking with your provider.
How can I take care of myself?

Your friends and family should know first aid for seizures and CPR. When you have a seizure, they should:
Help you lie down on a bed or the floor.
Loosen clothing around your neck and remove eyeglasses.
Not try to hold you down. If possible, they should roll you onto your left side and gently hold you there. This position will help keep you from choking on vomit if you start vomiting. Objects should be moved away from you to avoid injury.
Check to make sure you are breathing.
Not put anything in your mouth. (The risk of biting your tongue is less than the danger of inhaling or being injured by anything put in your mouth. You will not swallow your tongue.)
Not move you during a seizure unless there is danger of injury.
After the seizure is over, let you rest while you wake up.

Someone should call 911 for emergency help if you are having a seizure and:
It is the first time you have had a seizure.
You have stopped breathing.
The seizure lasts 5 minutes or longer.
You have another seizure soon after the first one stopped.
You are not fully awake within a few minutes after the seizure.
Your lips or face look blue.
You fall and hit your head during a seizure.
A seizure happens after a head injury.

If you are having a seizure and not breathing, someone should start giving you CPR and keep giving it until the ambulance arrives.

If you keep having seizures one right after another or have one seizure for a long time, it is dangerous because you may not be getting enough oxygen. It is a medical emergency and you will need help.

Ways to care for yourself include:
Follow the treatment prescribed by your healthcare provider. Take medicine exactly as prescribed. Do not increase how much you take or how often you take it.
Eat a healthy diet and create a balance of work, rest, recreation, and exercise in your life.
Wear a medical ID bracelet or necklace so others will know about your condition.
Tell family, friends, and co-workers what to do if you have a seizure.
If your seizures are not well controlled, you should avoid high-risk activities that would be unsafe if you had a seizure. Some examples of risky activities might include swimming alone, cycling on a highway, scuba diving, or skiing. Ask your healthcare provider which activities are safe for you.
Avoid high-risk jobs that involve heavy or fast-moving equipment, heights, bodies of water, or other situations where you or others might be injured if you have a seizure.
Ask your provider when you may safely drive a car again. Check with your state’s Department of Motor Vehicles for rules about reporting a history of seizures.
Keep a positive attitude and develop ways to lessen stress.
Keep all of your follow-up appointments with your provider.
Call your healthcare provider if:
You have side effects from your medicine.
You keep having seizures and you are taking your medicine correctly.
The seizures change–for example, they happen more often or last longer.
You are a woman who takes medicines to prevent seizures and you want to get pregnant or you are pregnant.
You have any symptoms that worry you.

How can I help prevent seizures?

To help prevent further seizures:
Take your medicine as directed. Never skip a dose or stop taking your medicine without first checking with your provider.
Make sure you get enough sleep every night. Getting too little sleep can be a major cause of seizures if you have a seizure disorder.
Avoid alcohol.
Avoid mood-altering drugs, including stimulants and sedatives.
If you start having a fever, lower it right away with aspirin or acetaminophen. (Check with your healthcare provider before you give any medicine that contains aspirin or salicylates to a child or teen. This includes medicines like baby aspirin, some cold medicines, and Pepto-Bismol. Children and teens who take aspirin are at risk for a serious illness called Reye’s syndrome.)

Primary Interhemispheric Subdural Empyemas - A report of three cases and review of literature
Abstract:
Interhemispheric subdural empyema is an uncommon condition and is considered neurosurgical emergency. These are generally seen following neglected oto-rhinological infection, but may be post traumatic or iatrogenic in origin. The source of infection can be frequently found, but in few cases no source of infection can be identified, called primary empyemas. These primary interhemispheric subdural empyemas are even rare. They can present with a rapid progression of symptoms and can carry poor prognosis. Early intervention with craniotomy and appropriate antibiotics can improve the condition of these patients.
We present three cases of primary interhemispheric empyemas who underwent emergency craniotomy and evacuation followed by antibiotics for 6 weeks. All the patients had excellent recovery on mean follow up of 10 years.
Key words:
Interhemispheric subdural empyema, neurosurgical emergency, primary empyemas, craniotomy

Management of pediatric colloid cysts of anterior third ventricle-A review of 5 cases
Colloid cysts are congenital benign lesions, associated with more aggressive clinical and radiological picture in children than in adults. We present our experience in management of five pediatric patients with colloid cyst of the anterior third ventricle. They have an excellent chance of surgical cure, or they can be devastating and even fatal, if not recognized on time and treated.

Material and methods:
Five pediatric patients (aged 16 years or less) who were surgically treated for a colloid cyst, between 1987 and 2011 were analyzed. The clinical features included raised intracranial pressure in all five cases, of which one patient was brought unconscious with decerebrate posturing. Computed Tomography (CT) scan of the brain was done in all patients. The density of the lesion, enhancement with contrast and the presence of hydrocephalus were analyzed. Four patients underwent a detailed postoperative neurological assessment.
Results:
Three patients underwent the transcallosal-transforaminal approach and total excision of the lesion. One patient underwent revision of the pre-existing ventriculoperitoneal shunt. One patient who was brought in an unconscious state, an external ventricular drain was inserted and she was ventilated. She died four hours after the admission. On follow up, none of the three patients who underwent the transcallosal-transforaminal approach had disconnection syndromes or behavioral disturbances.
Conclusion:
Colloid cysts in children are rarer and more aggressive than their adult counterparts. It is surgically curable. Early detection and total excision of the lesion is a permanent cure with minimum morbidity, when compared to the natural history of the disease. The limited anterior callosotomy does not result in disconnection syndromes or behavioral disturbance.
Key words: Colloid cyst, pediatric, transcallosal-transforaminal, anterior third ventricle, disconnection syndrome.
