[Features of schizoid states, constitutional and acquired]

The authors conducted a clinical comparison of schizoid traits of asthenic pole in 2 nozological heterogenic groups of patients. In one group they were of a constitutional character (the group of effusive schizoids), in the other--they were formed following a schizophrenic attack (the group of patients with mildly progressive schizophrenia in the state of remission of asthenic type). It was possible to demonstrate significant differences between the patients of these groups not only in specific schizophrenic traits (autism, the emotional sphere, social adaptation), but in their development. These differences testify to the existence of constitutionally conditioned stable schizoid states and the necessity to distinguish them from acquired psychopathic traits of the schizoid spectrum.
