Epilepsy: All you need to know.

What is epilepsy?
Epilepsy is a recurring outward manifestation of a problem with the brain. The medical definition of epilepsy is ‘repeated seizures or convulsions (or fits) due to a brain problem.’

How does epilepsy occur?
The brain is made up of billions of nerve cells and connections which work together in a delicate pattern to move body muscles and understand whatever the body is experiencing. The normal brain is constantly producing electrical rhythms in an orderly way. However, a short circuiting of the wiring can lead to overloading of the brain causing it to stop functioning correctly and everything can become jumbled up. This misfiring can last a few seconds or be prolonged and is called a seizure or fit. Many fits is called epilepsy and someone who is having repeated fits can be epileptic.

What causes epilepsy?
Anything which can cause scarring in the brain and therefore a break in the connection of nerve cells to each other can cause epilepsy. Epilepsy can be congenital (a baby is born with it) or acquired (a person develops it after birth). It can have an obvious direct cause such as a brain tumour, head injury, stroke, and brain infection; or have no clear cause. In fact for up to 50% of patients with epilepsy there is no obvious cause. It is important to know that an isolated, single seizure does not mean a person has epilepsy. Epilepsy by definition is a chronic condition with recurring seizures. Many people can have a one-time seizure because they were very dehydrated, or had abnormal levels of substances in the blood (e.g. glucose, magnesium, calcium).

What does a seizure (epileptic fit) look like?
It all depends on the type of epilepsy, but there are 3 common manifestations. There is the simple partial type in which a part of the brain is occasionally disrupted, manifesting in the form of repeated movements of a part of the body, but the person does not lose consciousness and is fully aware of what is going on. Then there is the complex partial type, in which a part of the brain is occasionally disrupted, manifesting in the form of decreased awareness with or without repeated movements of a part of the body. Finally, there is the generalized type, in which the entire brain is disrupted at once and these patients lose consciousness frequently accompanied by jerking around, foaming at the mouth, and involuntarily urinating on themselves. A seizure can start off as complex partial and then become generalized. About 90% of seizures are self-limiting lasting seconds to no more than 5 minutes. After a complex or generalized seizure has ended, patients can be disoriented or sleepy for several minutes thereafter. If a seizure lasts for more than 10 minutes, that is unusual and is a reason to take the patient to the hospital as quickly as possible. Self-limiting seizures do not cause brain damage, but prolonged seizures certainly can, and so it is important for the patient to get to the hospital where drugs can be administered to arrest the seizure promptly.

What are the myths and misconceptions about epilepsy?
•Epilepsy is due to a spiritual attack and that the demon must be cast out of the patient. This is incorrect. Unfortunately, because demons have been thought responsible, they are often ‘beaten’ out of sufferers in many churches and herbalist homes, needlessly subjecting several patients to grievous bodily harm and even death.
• Epilepsy is not contagious. It has never been and it will never be. You cannot contract epilepsy by touching the sufferer or coming in contact with their saliva. It is not an infection and is not caused by a virus or germ.
• Epilepsy is not a mental illness. Seizures are mainly a symptom that there is a physical problem, like a scar, on the brain. Some people with epilepsy are extremely clever, others are of average intelligence and some have learning difficulties. Just like normal people in the population, really.
• Epilepsy is not a bar to success in life. Many people with epilepsy enjoy highly successful lives.
• Epilepsy is not generally an inherited condition. Although, there can be a genetic predisposition, more often than not, there is no family history of epilepsy.
What are the treatment options available to patients?

Epilepsy can be treated, controlled and rarely, cured. Epilepsy can be well controlled by medications. These drugs can reduce the frequency and severity of the seizures by keeping the nerve cells quiet and making it difficult for them to short circuit. Sometimes, a patient may need to be on more than one seizure medication to control epilepsy. In fact, epilepsy is not necessarily a lifelong condition. Many people who have been seizure free for three or four years have their medications carefully withdrawn under close medical supervision and remain free for the rest of their lives. Surgery can also be successful in eliminating certain types of seizures.

Are the drugs within reach and what are the cost implications?
Many of the drugs are available in Nigeria and there are many reputable local manufacturers. The main drugs mentioned above are available and may cost up to N300 per day for effective treatment. More expensive drugs may be necessary if control is not adequate. Many of the very expensive drugs are not available in Nigeria. Other ways to treat epilepsy include surgery. Treating the cause by removing the abnormality (e.g. scar or brain tumour) may lead to cure. Surgery can be expensive. Financial cost for surgery could be as low as N100, 000 to as high as N1m or more.

How should people treat someone having a seizure?
The best management for the patient at the time of a fit is to make sure they do not come to harm or injure themselves during the period of loss of consciousness (See figure below). Move objects that can harm the person, out of the way. If possible, place a pillow under the person’s head so that the head doesn’t bang against the floor causing injury. Keep calm and try not to panic. Let the seizure run its course and do not hold them down. If possible move them to a comfortable place and let them sleep or at least have a good rest once the seizure is over. If the seizure does not stop, or it stops then keeps recurring without the person waking up in between episodes, please get medical help immediately. Take the person to the nearest hospital where they can be helped. We have heard of some communities where burning the feet of the sufferer is supposed to be helpful! Please do not do this. Also, the practice of putting a stick or spoon in their mouth is not necessary and can be damaging. Finally, in some communities, various concoctions (urine, drugs and alcohol) are poured down the throat of the sufferer. This can lead to choking, aspiration, pneumonia and death.

How can we position our health system to better respond to epilepsy?
Anyone can be affected by epilepsy. We need to create more awareness about nature of epilepsy and its capacity to be treated (See figure below). Policy makers at all levels of government should ensure that the drugs are more widely available and cheaper. Many patients stop taking their medications because of the poor access to and high cost of drugs, thereby leading to seizure recurrence. Finally, given the paucity of neurologists and neurosurgeons in Nigeria, efforts must be made to train more specialists and position them in all the six geopolitical zones for wider care coverage.

How can you and the Epilepsy Association be reached?
