Research Abstract

We found a case with schizophrenia who is in pedigree with multiple affected individuals and had a frameshift mutation reducing enzymatic activity by 50% in glyoxalase1 gene. The case suggested possibility of carbonyl stress is involved in pathophysiology of schizophrenia and high plasma AGEs was detected in 46.7% of the patients. We studied on volatile organic compounds associated with schizophrenia to reveal pathophysiology of the disease(Arai et al. Arch Gen Psychiatry 2010). We detected volatile organic compounds contained in the air of the ward by using GCMS
