Epilepsy and Seizures

What is epilepsy?

Epilepsy is a neurological condition involving the brain that makes people more susceptible to having seizures. It is one of the most common disorders of the nervous system and affects people of all ages, races and ethnic background. Almost 3 million Americans live with epilepsy.

When a person has two or more seizures, he or she is considered to have epilepsy. There are many possible causes of epilepsy, including tumors, strokes, and brain damage from illness or injury. In many cases, there may be no detectable cause for epilepsy.

What is a seizure?

The brain is the center that controls and regulates all voluntary and involuntary responses in the body. It consists of nerve cells that normally communicate with each other through electrical activity.

A seizure occurs when part(s) of the brain receives a burst of abnormal electrical signals that temporarily interrupts normal electrical brain function.

in newborns and infants:

in children, adolescents, and adults:
