Seizure

Overview

This is a sudden burst of electrical activity in your brain. It overwhelms parts of your brain, usually for no more than a few minutes. Most seizures don't cause lasting harm.

Causes

Most commonly, seizures are caused by a brain disorder called "epilepsy." If you have this disorder, you may have seizures frequently. But seizures can have other causes, too. They can be caused by a high fever, low blood sodium or lack of sleep. They can result from medications, and from alcohol or drug abuse. They can be caused by a head injury or a stroke. And, seizures can be triggered by a brain tumor.

Symptoms

Seizures cause a wide range of symptoms. Depending on the type of seizure, you may lose consciousness or awareness. You may make uncontrollable jerking movements. You may stare. You may have feelings of confusion, fear, anxiety or déjà vu. And things may look, feel, taste or sound differently. Ask your doctor for a complete list of possible symptoms.

Treatment

Treatment depends on the type of seizure you're experiencing. For some people, monitoring is all that's needed. Or, medications may help. And some benefit from surgery. Your healthcare provider will create a care plan that's right for you.
