3.Causes: The causes of depression typically include biological factors (such as genetics, biochemistry, etc.), psychological and social factors (such as life events, family factors, etc.), while the causes of anxiety are usually related to biological factors (such as genetics, neurobiology, etc.) and psychological and social factors (such as life events, family factors, etc.).
