Epilepsy is the name of a neurological disease that takes many forms and occurs in attacks. Epilepsy is caused by a sudden activation of a large number of brain neurons. It appears generally as a momentary loss of consciousness and may be accompanied by involuntary and repeated spasms of one or more of the limbs. By the wide variety of brain areas involved and the types of abnormalities encountered, clinical manifestations vary and may take the form of a simple "blank", meaning a sudden and fleeting suspension of consciousness, or may take more complex and distressing forms with jolts throughout the body, rolling eyes, and a lack of consciousness, which extends after the cessation of movements. In forms of epilepsy called "partial", signs can be motor or sensory and affect only one part of the body. The epileptic disorder often appears in childhood or early adulthood and an electroencephalogram and brain imaging test can confirm the disease and the treatment. Epilepsy can be controlled by antiepileptic drugs, in most cases, and the patient must be informed of rules for preventing new attacks.
