The cholinergic system: An emerging drug target for schizophrenia

Abstract

Background: Cognitive deficits are amongst the most socially debilitating and least effectively treated symptoms of schizophrenia. The cholinergic system is a promising target for the design of novel drugs that can more effectively treat these symptoms.
