Circadian abnormalities, molecular clock gene and chronobiological treatment for psychiatric disorders

Anomalies of the circadian rhythm are important in mental illnesses such as anxiety, schizophrenia, bipolar disorder, and depression. Dysregulated molecular clock genes, including CLOCK, BMAL1, PER, and CRY, are frequently linked to disturbances in hormone production, sleep-wake cycles, and neurotransmitter modulation. These genes affect mood, thought, and behaviour by controlling the body's internal clock. Circadian system dysfunctions can worsen mental health issues by impairing cognitive function, mood swings, and sleep patterns. Restoring circadian stability is the goal of chronobiology-based therapies. Bipolar illness and seasonal affective disorder (SAD) are two mood disorders that are commonly treated using light therapy. Supplementing with melatonin aids in the regulation of sleep patterns, and chronotherapy methods like wake therapy and sleep phase shifting can quickly alleviate depression symptoms. Pharmacological drugs that target circadian rhythms may improve therapeutic efficacy, according to recent studies. Managing mental illnesses may be possible by coordinating behavioural and medicinal treatments with circadian cycles. Psychiatric care must address circadian disturbance since it can improve mood stability, cognitive function, and general health. There is potential to improve the outcomes of psychiatric disorders by comprehending molecular clock mechanisms and incorporating chronotherapeutic techniques.
