- Original description
Schizophrenia is a common, long-term mental illness. It causes problems with thoughts, feelings, and behavior, including positive symptoms (hallucinations, delusions), negative symptoms (lack of emotion, motivation), and cognitive impairment (trouble with thinking, memory, and attention). While antipsychotic drugs effectively treat positive symptoms, they don't help much with cognitive impairment.This study will examine how the tryptophan-kynurenine pathway in the brain contributes to cognitive problems in people having their first episode of schizophrenia and treated with a single antipsychotic. Our goal is to create models for early detection of cognitive impairment in schizophrenia and find potential targets for new treatments to improve thinking and memory.Read full original descriptionShow less
