[Disorders of emotional control in schizophrenia and unilateral brain damage].
Although, emotions play a crucial role in schizophrenia, the changes in emotional dimension still remain controversial. The aim of our work was: 1) to compare the disorders of emotional control between the examined groups: S--non-chronic schizophrenic patients (n = 50), CS--chronic schizophrenic patients (n = 50), N--healthy controls (n = 50), R--right brain-damaged patients (n = 30), and L--left brain-damaged patients (n = 30), 2) to assess a level of impairment of emotional control, its relation to lateralised hemisphere damage and chronicity of schizophrenic process. All psychiatric subjects were diagnosed as paranoid schizophrenics according to DSM-IV criteria and were scored on the PANSS scale after four weeks of neuroleptic treatment. Brain-damaged patients were included if they experienced single-episode cerebrovascular accidents causing right or left hemisphere damage (confirmed in CT scan reports). The neurological patients were examined at least 3 weeks after the onset of cerebrovascular episode. Emotional control was assessed using Brzeziński Questionnaire of Emotional Control aimed at the evaluation of: 1) control in perception and interpretation of emotive situation, 2) emotional arousal, 3) emotional-rational motivation, and 4) acting caused by emotions. Our results revealed significantly greater impairment of emotional control in schizophrenics (chronic schizophrenics, in particular) compared to healthy volunteers. Chronicity of the schizophrenic process seemed to intensify emotional control impairment. Interestingly, no significant qualitative and quantitative differences in emotional control mechanism between unilateral brain-damaged patients and the control group were found.
