[Electroencephalographic study of functional metabolic encephalopathies and comas during parenteral alimentation].

This review deals with the common E.E.G. characteristics of dysmetabolic encephalopathies and described the particular features of hepatic, respiratory and renal encephalopathies, as well as those resulting from a disturbance in carbohydrate, water and electrolyte metabolism. These now classical data are compared with the principal electroclinical appearances seen during parenteral alimentation : slow, ample wases, non-reactive, associated with a calm coma; overall depression of basal rhythm, with excessive myogram activity and corresponding to paroxysms of muscular hypertonia seen during the coma.
