[Clinico-psychopathologic features of amentia in kidney diseases]

The paper contains some results of a clinico-psychopathological analysis of the amentive syndrome in patients with nephrogenic psychoses. Among 97 patients studied 25 showed amentive states. Pathogenetic possibilities of uremic toxicosis, depending upon the intensity and severity of which the amentive symptomatology may develop in different ways is discussed. The pathoplastic significance of renal hypertension is described in detail. Two variants of nephrogenic amentia are distinguished and described (hyperkinetic and hypokinetic) which differ by their intensity of psychotic symptoms, rate of development and the severity of the outcome. It is demonstrated that the amentive syndrome in such cases has certain nozological information, which facilitates significantly a differential diagnosis.
