[The petit-mal-status].
In the light of three case histories, other personal observations and the literature, the clinical and electroencephalographical differences between absences in the limited sense and continuous LENNOX petit-mal state are described and the problems of the latter discussed. As a rule, petit-mal state is diagnosed as such in young people or adults, and practically never before the 10th year of life. In about two thirds of cases, its clinical symptomatology consists of a twilight condition lasting some hours to a few days, coupled with inertia and apathy. The remaining third of the patients usually experience milder disturbances, e.g. in the form of concentration difficulties, tiredness, and (more rarely) severe forms including lethargy. The EEG correlate of a petit-mal state is made up of continuous bilaterally synchronous, frontally marked (less frequently with exclusively frontal localization), usually irregular spike waves or poly-spike waves, which frequently occur in only rudimentary forms and register a frequency of 2 1/2-4 c/sec. For the treatment of petit-mal state, benzodiazepines and in particular clonazepam (Rivotril) (1-2 mg i.v.) are recommended. During the interval condition the same therapy as with an absence epilepsy, e.g. succinimides or dipropylacetate (Depakine) is administered. Anti-grand-mal remedies, especially hydantoins, may trigger petit-mal status.
