Overview of Cognition and Neurotransmitters in Schizophrenia

Abstract

Schizophrenia is a complex mental disorder characterized by a wide range of symptoms, including psychosis, hallucinations, delusions, and cognitive deficits. While much research has focused on the positive and negative symptoms of schizophrenia, such as hallucinations and lack of motivation, cognitive deficits are also prominent features of the disorder but have been understudied. In this article, we discuss cognition in schizophrenia, including the maintenance of cognitive function and the deficits that are commonly observed. We also review typical treatments for schizophrenia and how they target neurotransmitter dysfunction in the brain. Despite the availability of antipsychotic medications that primarily target positive symptoms, current treatments have limited efficacy in improving cognitive deficits in schizophrenia. We highlight the need for further research and development of novel treatments that specifically target cognitive deficits in schizophrenia to improve the overall functioning and quality of life for individuals with this debilitating disorder.
