[Clinical significance of sleep status following-large scale epileptic attacks (grand mal)]

Certain clinical criteria of grand mal seizures, and particularly the post-convulsive sleep phase (PCS), appear to be manifestations of some more deep-rooted disturbance of the functional cerebral mechanisms. The symptoms of the chronic organic psychosyndrome were observed distinctly more often in patients with PCS than in those without it. The frequency of seizures is also important when considering the cause of chronic brain damage. Etiological aspects (genuinely-symptomatological) appear to be of secondary importance.
