What is Epilepsy?
A seizure happens when the electrical system of the brain malfunctions. Instead of discharging electrical energy in a controlled manner, the brain cells keep firing. The result may be a surge of energy through the brain, causing unconsciousness and contractions of the muscles.
If only part of the brain is affected, it may cloud awareness, block normal communication, and produce a variety of undirected, uncontrolled, unorganized movements.
Most seizures last only a minute or two, although confusion afterwards may last longer. An epilepsy syndrome is defined by a collection of similar factors, such as type of seizure, when they developed in life, and response to treatment.
The Brain and Epilepsy
The human brain is the source of human epilepsy. Although the symptoms of a seizure may affect any part of the body, the electrical events that produce the symptoms occur in the brain. The location of that event, the extent of its reach with the tissue of the brain, and how long it lasts all have profound effects.
