Epilepsy is a nervous system condition. It causes repeated, sudden, brief changes in the brain’s electrical activity. These changes cause various types of symptoms. Epileptic episodes are called seizures or convulsions. During a seizure, brain cells fire uncontrollably at up to four times their normal rate. Seizures temporarily affect the way a person behaves, moves, thinks or feels. There are two main types of seizures: A primary generalized seizure involves the entire brain.
A partial seizure begins in one brain area. It affects only part of the brain. However, a partial seizure can turn into a generalized seizure. Many conditions can affect the brain and trigger epilepsy. These include: Brain injury, either before or after birth Brain tumors Infections, especially meningitis and encephalitis Genetic conditions Abnormal blood vessels in the brain Lead poisoning In most people with epilepsy, the specific cause is unknown. Symptoms The symptoms of epilepsy vary. They depend on how much of the brain is affected, and where the affected area is located.

After the seizure, the person has no memory of the episode. Status epilepticus —Occurs when a person has a generalized seizure that lasts 20 minutes or more. It can also result from a series of seizures without fully regaining consciousness. This is a life-threatening medical emergency. Diagnosis You may not have any seizure symptoms when you visit your doctor’s office. For this reason, it is important to enlist the help of anyone who has witnessed your seizure. Ask that person to describe exactly what they saw: what happened at the start, what happened next.
Write this description down for your doctor. This description will help your doctor determine the type of seizure you had. It will also help to decide on appropriate treatment.

Other types of brain scans also may be needed. Your doctor may want to check whether your seizures are related to causes outside the brain. To do so, he or she may order basic lab tests. These can include blood tests, urinalysis and an electrocardiogram (EKG). Expected Duration Epilepsy can be a lifelong condition. But many people with a history of multiple seizures eventually will stop having seizures.
People who are younger when seizures start are more likely to stop having seizures. The same is true for people who have a normal neurological examination. For most people with epilepsy, seizures can be controlled with medication. Prevention The cause of most cases of epilepsy remains unknown. Therefore, there is no way to prevent seizures. To help prevent epilepsy caused by head injury, you can: Wear seat belts while driving. Equip your car with air bags. Wear an approved helmet while skating, riding a motorcycle or bicycling. Use protective headgear for sports.
Anyone with an active seizure disorder should take precautions. These will minimize the risk of injury if a seizure should occur. For this reason, people with epilepsy are advised not to operate a motor vehicle for at least six months after the most recent seizure. The same applies to operating other dangerous machinery. People with epilepsy should consider wearing some sort of medical identification that describes their condition. This will provide important information to emergency medical personnel. Treatment In most cases, treatment begins with one of the many anti-epileptic medications.
The type of medication used depends on the type of seizure being treated. When medication fails to control a person’s seizures, surgery may be considered. The decision to perform surgery depends on many factors. These include: Frequency and severity of seizures Patient’s risk of brain damage or other injury from frequent seizures Effect on quality of life Patient’s overall health Likelihood that surgery will control seizure episodes Status epilepticus is a life-threatening medical emergency. It is treated with medications given intravenously or rectally. Protective measures are also taken.
These measures keep the person’s airway open. And they help to prevent injury to the person’s head and tongue.
