The clinical states accompanying these EEG abnormalities may be classified as: 1) absence with no overt manifestations, for example, simple absence; epileptic absence; subclinical absence; 2) absence with clonic movements, for example, myoclonic absence; 3) absence with atonic states, for example, atonic absence; 4) absence with tonic contractions, for example, hypertonic muscular contraction; 5) absence with automatisms, for example, various stereotypic movements, usually of the face or hands; 6) absence with atypical features, for example, bizarre motor activity.
