Neuropsychological syndromes of non-psychotic mental disorders of youthful age

Seventy male patients with non-psychotic mental disorders of youthful age (mean age 19.2 +/- 3.7), were studied using A.R. Luria neuropsychological syndrome analysis. Patients were stratified into 3 groups by diagnosis: cyclothymia (20 patients), pubertal decompensation of schizoid personality disorder (30 patients) and schizotypal personality disorder (20 patients). It has been shown that the neuropsychological changes indicate the dysfunction of the amygdale/temporal region in patients of the first group and frontal/thalamic/parietal connections in the patients of two other groups. There were interhemispheric differences between patients with personality disorder and schizotypal personality disorder: left hemisphere dysfunction was characteristic of schizotypal disorder and right hemisphere deficit (neurocognitive deficit) was found in patients with personality disorder.
