[Neuroanatomical brain profile of juvenile shiftlike schizophrenia: morphometry of grey matter in the prefrontal cortex and subcortical structures].

Aim: To determine neuroanatomical peculiarities of grey matter in some regions of the prefrontal cortex and several subcortical structures in patients with juvenile shift like schizophrenia (F20 ICD-10).

Material And Methods: Forty-three young male patients and 54 mentally healthy men without family history of mental diseases underwent structural MRI with T1 high resolution images.

Results: As compared to mentally healthy subjects, there was a decrease of grey matter thickness in all tested regions of the prefrontal cortex in patients.

[Neuromorphologic and psychological correlates of electrical brain activity in patients with schizophrenia and their relatives].

The study aimed at elucidation of potential correlations between EEG features, neuromorphologic and psychological characteristics in patients with schizophrenia and in subjects with familial predisposition to the disease. EEG has been conducted in 71 patients, 162 first-degree relatives of schizophrenia subjects and 67 healthy controls. In the patients and relatives, correlations of power indices for 7 frequency ranges of resting EEG with computed tomography and cognitive parameters were analyzed.

[Rigidity of psyche processes and factors predisposing to schizophrenia].

To evaluate the rigidity of psychic processes (RPP) as a factor predisposing (vulnerability) to schizophrenia and to study interactions between RPP and other susceptibility factors, psychological characteristics and magnetic resonance tomography data have been studied in 26 families with schizophrenia. Correlation, cluster and regression analyses and trait phenotypic variance decomposing into genetic and environmental components for heritability estimation were used. RPP indices in patients with schizophrenia and their relatives differed significantly from those in the control group of healthy subjects without positive family history of schizophrenia.

[The aged patient's first visit to the outpatient psychiatric clinic].

160 patients over 60 years of age appealed to gerontologic unit of out-patient psychiatric clinic for the first time. The patients were divided into two main groups: with organic mental disorders (OMD) and with functional mental disorders (FMD) (79 and 81 patients, respectively). In the group of OMD the main form of disturbances were cases with dementia (74.
