title: Prolonged psychic epileptic seizures: a study of the absence status.
abstract: Long-lived epileptic seizures associated with spike-and-wave complexes are presently considered to be the absence status, i.e., the generalized nonconvulsive status. EEG radiotelemetry allowed us to record three prolonged seizures of 3 epileptic patients. Clinical manifestations included selective rather than global impairment of higher cortical functions. Clinical impairment appeared only when patients were in a state of activity and if those altered functions were used. EEG abnormalities were diffuse, but among them spike-and-wave complexes were never diffuse. It was impossible to establish close electroclinical correlation. However, the clinical and electrical evolution was roughly isomorphic, i.e., cyclic. Major clinical manifestations were associated with spikes rather than with slow waves. Lastly, patients showed common ictal psychopathological symptoms. The problem of classifying such seizures in either the generalized or partial status is discussed. The role of selective impairment of mental functions in psychopathological symptoms is also dealth with.
