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.

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.
