[Systematics and differentiation of personality disorders in children and adolescents with behavioral disorders].

The author discusses some problems of systematization and differential diagnoses of personality disorders which are accompanied by disturbances of behaviour in children and adolescents. An original classification of personality disorders and transient personality reactions in childhood and adolescence is proposed. Special attention is paid to the criteria of delineating pathological and nonpathological forms of personality disorders and personality reactions in this group of children as well as to the differential diagnosis of constitutional and organic psychopathy. On the other hand residual-organic psychopath-like conditions and psychogenic pathocharacterological personality development are analyzed.
