s randomly with no control over body movements. The individual's activity does not cease during the seizure, but behavior is random and totally unrelated to the individual's surroundings. This form of seizure may be preceded by an aura (a warning sensation characterized by feelings of fear, abdominal discomfort, dizziness, or strange odors and sensations). Absence seizures, rare in adults, are characterized by a sudden, momentary loss or impairment of consciousness. Overt symptoms are often as slight as an upward staring of the eyes, a staggering gait, or a twitching of the facial muscles. No aura occurs and the person often resumes activity without realizing that the seizure has occurred. In a second type of epilepsy, known as generalized seizure, tonic clonic, grand mal, or convulsion, the whole brain is involved. This type of seizure is often characterized by an involuntary scream, caused by contraction of the muscles that control breathing. As loss of consciousness sets in, the entire body is gripped by a jerking muscular contraction. The face reddens, breathing stops, and the back arches. Then, alternate contractions and relaxations of the muscles throw the body into sometimes violent agitation such that the person may be subject to serious injury. After the convulsion subsides, the person is exhausted and may sleep heavily. Confusion, nausea, and sore muscles are often experienced, and the individual may have no memory of the seizure. Attacks occur at varying intervals, in some people as seldom as once a year and in others as frequently as several times a day. About 8 percent of those subject to generalized seizures may have status epilepticus, in which seizures occur successively with no intervening periods of consciousness. These attacks may be fatal unless treated promptly with the drug diazepam.Treatment for an Incurable DisorderThere is no cure for epilepsy but symptoms of the disorder may be treated with dr...
