[The structure of catatonia in depression and depressive-delusional conditions].

The results are partially consistent with earlier investigations in other groups of patients with catatonic features. Schizophrenia is characterized by the presence of parakinetic manifestations of catatonia, the greater severity of hypokinetic manifestations and a higher degree of catatonia polymorphism, in contrast to affective disorders. The results indicate the heterogeneity of catatonia associated with the manifestations of depression and with concomitant symptoms. Catatonic subsyndromes may differ not only phenomenologically, but also neurobiologically.
