[Diagnostic problems in hysterical seizures].

The steeply increasing number of publications on psychogenic seizures during the last few years does not appear to be due to an increase in their incidence but to the introduction of videography into clinical practice. By this method, analysis of seizures and differential diagnosis between hysterical and epileptic seizures has become much easier. Out of the total of 40 seizures which have been recorded on video at the Neurological Department of the University of Berne during 1982 through 1983, 13 were obviously of psychic origin. The case of a patient with both hysterical and epileptic seizures is reported to illustrate the diagnostic difficulties in differentiating these two types of attack.
