Epilepsy is a neurological condition that from time to time produces brief disturbances in the normal electrical functions of the brain. Normal brain function is made possible by millions of tiny electrical charges passing between nerve cells in the brain and to all parts of the body. When someone has epilepsy, this normal pattern may be interrupted by intermittent bursts of electrical energy that are much more intense than usual. They may affect a person’s consciousness, bodily movements or sensations for a short time.

 

These physical changes are called epileptic seizures. That is why epilepsy is sometimes called a seizure disorder. The unusual bursts of energy may occur in just one area of the brain (partial seizures), or may affect nerve cells throughout the brain (generalized seizures). Normal brain function cannot return until the electrical bursts subside. Conditions in the brain that produce these episodes may have been present since birth, or they may develop later in life due to injury, infections, structural abnormalities in the brain, exposure to toxic agents, or for reasons that are still not well understood. Many illnesses or severe injuries can affect the brain enough to produce a single seizure. When seizures continue to occur for unknown reasons or because of an underlying problem that cannot be corrected, the condition is known as epilepsy. Epilepsy affects people of all ages, all nations, and all races. Epilepsy can also occur in animals, including dogs, cats, rabbits, and mice.
