Depression is a multifaceted disorder with significant psychological, physical, and social impacts. It involves a range of symptoms that affect mood, behavior, and physical health, requiring persistent presence for diagnosis. The disorder severely limits psychosocial functioning and is prevalent worldwide, contributing to a substantial burden of disease. Biological research highlights abnormalities in specific brain regions and stress-induced changes in neural circuits. Theoretical perspectives suggest that depression may have adaptive functions related to social stress. Understanding these diverse aspects is essential for effective diagnosis, management, and treatment of depression.
