Facilitative Effect of Serotonin1A Receptor Agonists on Cognition in Patients with Schizophrenia
Disturbances of cognitive function are considered to largely affect the outcome in patients with schizophrenia. There is much attention to the role of psychotropic compounds acting on serotonin (5-HT) receptors in ameliorating cognitive deficits of the disease. Among the 5-HT receptor subtypes, the 5-HT1A receptor is attracting particular interests as a potential target for enhancing cognition, based on preclinical and clinical evidence. The neural network underlying the ability of 5-HT1A agonists to treat cognitive impairments of schizophrenia likely includes dopamine, glutamate, and gamma-aminobutyric acid neurons. Recent advances of electrophysiological measures, such as event-related potentials, have provided insights into facilitative effects on cognition of some atypical antipsychotic drugs or related compounds acting directly or indirectly on 5-HT1A receptors. These considerations are expected to promote the development of novel therapeutics for the betterment of functional outcome in people suffering from schizophrenia.
