Epilepsy is a group of syndromes characterized by recurring seizures. Epileptic syndromes are classi?ed by speci?c patterns of clinical features, including age of onset, family history, and seizure type
Pathophysiology of Epilepsy
Messages from the body are carried by the neurons (nerve cells) of the brain by means of discharges of electrochemical energy that sweep along them. These impulses occur in bursts whenever a nerve cell has a task to perform. Sometimes, these cells or groups of cells continue ?ring after a task is ?nished. During the period of unwanted discharges, parts of the body controlled by the errant cells may perform erratically. Resultant dysfunction ranges from mild to incapacitating and often causes unconsciousness (Greenberg, 2001; Hickey, 2003). When these uncontrolled, abnormal discharges occur repeatedly, a person is said to have an
epileptic syndrome (Schachter, 2001).
Epilepsy is not associated with intellectual level. People with epilepsy without other brain or nervous system disabilities fall within the same intelligence ranges as the overall population.
Epilepsy is not synonymous with mental retardation or illness.Many who are developmentally disabled because of serious neurologic damage, however, have epilepsy as well.
Causes of Epilepsy
* a brain injury, such as from a car crash or bike accident
* an infection or illness that affected the developing brain of a fetus during pregnancy
* lack of oxygen to an infant's brain during childbirth
* meningitis, encephalitis, or any other type of infection that affects the brain
* brain tumors or strokes
* poisoning, such as lead or alcohol poisoning
