Also, mitochondria are crucial for neurogenesis and neuronal functions. Melatonin is an indole analog hormone, which is generally produced by the pineal gland. It plays a vital role in circadian rhythm and act as a powerful antioxidant by scavenging free radicals, immunomodulators, and anticancer agents. Schizophrenia and mood disorders are the two major psychiatric disorders. Disturbances of sleep and circadian rhythms are well-known symptoms of schizophrenia and mood disorders (bipolar disorder, major depression). Since melatonin has a regulator effect on circadian rhythm and sleep quality, it has a close interaction with schizophrenia and mood disorders. Herein, we aimed to summarize the effects of melatonin on mitochondrial activity in schizophrenia and mood disorders.
