[Syndromologic independence of amentia]

On the basis of long-term clinical observations of patients with amentive states within the framework of somatogenic, infectious, intoxicational, vascular exogenous-organic, reactive and schizophrenic psychoses the author attempts to claim the nosological independence of the amentive syndrome. The paper contains data on the nosological specificity of the modified syndrome in various disorders. The independence of the amentive syndrome is also grounded by clinico-pathological data (EEG and biochemical).
