absence


absence
Paroxysmal attacks of impaired consciousness, occasionally accompanied by spasm or twitching of cephalic muscles, which usually can be brought on by hyperventilation; depending on the type and severity of the a., the EEG may show an abrupt onset of a 3-sec spike and wave pattern as in simple a., or in atypical cases, a 4-sec spike and wave or faster spike complexes. The clinical states accompanying these EEG abnormalities may be classified as: 1) a. with no overt manifestations, e.g., simple a.; epileptic a.; subclinical a.; 2) a. with clonic movements, e.g., myoclonic a.; 3) a. with atonic states, e.g., atonic a.; 4) a. with tonic contractions, e.g., hypertonic muscular contraction; 5) a. with automatisms, e.g., various stereotyped movements, usually of the face or hands; 6) a. with atypical features, e.g., bizarre motor activity. [L. absentia]
