Epilepsy is a common name used for a cluster of disorders that cause disorder in electrical signalling in the brain. Like a computer or a building, the brain is an extremely complex electrical system, motorized by roughly 80 pulses of energy per second. These pulses move to and fro among nerve cells to create thoughts, feelings, and memories.
Epilepsy is a situation in which a person has regular seizures. A seizure is abnormal, uncontrollable discharging of the brain's nerve cells, resulting in a short-term disorder of sensory or mental function. There are several types of seizures, depending chiefly on what division of the brain is involved. The word epilepsy says nothing about the form or cause of seizure, only that the seizures occur again and again.
An epileptic seizure takes place when energy pulses come extremely fast approximately 500 per second for a spell because of an electrical abnormality in the brain. This brief electrical flow can take place in small part of the brain, or it may affect the complete brain. Depending on the part of the brain that is affected, the surge of electrical energy can cause.
Epilepsy is popularly known as a seizure disorder since the tendency is to have periodic seizures. Epileptic seizures differ in severity and occurrence. While some persons may experience two or three seizures during their complete lifetime, may others will experience several seizures in a day. Epilepsy is not contagious. A tendency toward epilepsy may be hereditary, but it cannot be caught like a cold from other person.
