Higher nervous activity in psychiatric patients.

Abstract

A review is presented of studies of higher nervous activity in psychiatric patients. In neuroses and reactive psychoses the basic pathology appears to be centered around the psychogenic complex structures. In addition, neuroses as well as reactive psychoses reveal general disturbances of higher nervous activity. In the schizophrenic and manic depressive psychoses there are indications of disturbances in deep-lying brain structures. Both types of psychoses are heterogeneous groups of clinical conditions. An important task for future experimental studies is to establish the types of disturbances of higher nervous activity in well-defined clinically homogenous groups. The final section deals with prophylactic psychiatry, with special emphasis on Gantt's suggestions for an international project.
