Outline of Final Research Achievements

Our findings suggested that the neurocognitive features of carbonyl stress in schizophrenia may be associated with dysfunctions in visual perception, social cognition, processing speed, and attention. Moreover, we found that the relationship between reduction of pentosidine and high performance of cognitive functional tests, and prognosis was also improvement in outcomes. Especially, score of subtests, which relate to verbal comprehension and perceptual integration in WAIS-III, elevated.
Our results revealed the neurocognitive features of carbonyl stress, and the relevance of pentosidine and perfomance of cognitive functional tests and outcomes.
