MUSCARINIC M1 RECEPTOR, COGNITION AND SCHIZOPHREMIA

Abstract

Schizophrenia is a serious psychiatric illness that affects approximately 1% of Australia's population. Whilst the prominent symptom of schizophrenia is psychosis, the majority of subjects with schizophrenia also show deficits in cognition. Unlike psychotic symptoms, deficits in cognition do not respond well to current antipsychotic drug treatment. We have been investigating the possible role for changes in a family of receptors, called muscarinic receptors, in the pathology of schizophrenia for almost a decade. Our research has shown that two members of the muscarinic receptor family, the M1 and M4 receptors, may be differentially decreased in different brain regions of subjects with schizo..
