The present study was conducted with serum of twenty four patients of schizophrenia and twenty healthy volunteers; and selenium (Se) levels were determined by atomic absorption spectrophotometer. Serum Se levels were significantly increased in schizophrenia patients as compared to healthy controls. Soil content of Se in Rohtak was found to be lower as compared to Haryana state soil Se levels. These findings suggest that low Se levels in schizophrenia patients and soil may have a role in pathogenesis of schizophrenia.
Key words: Selenium, schizophrenia, geographical distribution.
