کارکردهای نوروسایکولوژیک برادران و خواهران بیماران مبتلا به اسکیزوفرنیای مستمر

Many studies suggest that the relatives of patients with schizophernia exhibit neuropsychological impairments that are similar to those seen among these patients. In this study some neuropsychological functioning of 10 patients with continuous schizophernia, and 19 of their healthy siblings (7 females and 12 males) were compared with the functioning of 24 normal control subjects (10 females and 14 males). The normal and sibiling groups were matched for agem gender, IQ, education, and handedness. The functions evaluated were abstract reasoning, motor ability, verbal memory, short-term memory, mental control, and visual memory which were assessed by similarities subtest of WAIS-R, Vigorimeter, Paired- Associate Vocabulary and Mental Control subtest of WMS, Digit Span and Digit Symbol of WAIS-R, and Benton Visual Retention test (BVRT), respecvively. Reuslts showed that siblings of the schizophernic patients performed significantly at a poorer level than control group in abstract reasoning (p<0.1) and visual memory (p<0.5) . On the other hand there was no significant differences between siblings and patients in mental control.
