What are the differences between endogenous depression and psychogenic depression?

　　The differences between endogenous depression and psychogenic depression include variations in etiology and pathogenesis, symptom presentation, onset characteristics, treatment focus, and prognosis. Both are types of depressive disorders and require clinical evaluation for accurate differentiation. If persistent low mood or reduced interest lasts for more than two weeks, prompt medical consultation is recommended.

　　1. Different Etiology and Pathogenesis: Endogenous depression is associated with biological factors such as genetics, neurotransmitter imbalances, and endocrine abnormalities. Psychogenic depression is triggered by major life events, psychological trauma, or chronic stress—rooted primarily in psychosocial factors, thus differing in underlying causes.

　　2. Different Symptom Presentation: Endogenous depression is characterized by core symptoms such as depressed mood, slowed thinking, and lack of energy, with a distinct pattern of worse symptoms in the morning and improvement at night. Psychogenic depression is often accompanied by anxiety and self-blame, with symptoms closely linked to triggering events, more pronounced emotional fluctuations, and different clinical manifestations.

　　3. Different Onset Characteristics: Endogenous depression often lacks clear triggers, has an insidious onset, and tends to have a longer disease course. Psychogenic depression usually develops abruptly, with onset closely related to identifiable stressors, and its progression is influenced by psychological adjustment, resulting in different patterns of onset.

　　4. Different Treatment Approaches: Endogenous depression is primarily treated with medication aimed at restoring neurotransmitter balance. Psychogenic depression emphasizes psychotherapy (e.g., cognitive-behavioral therapy) combined with lifestyle interventions, reflecting different therapeutic priorities.

　　5. Different Prognosis: Endogenous depression has a relatively higher relapse rate and often requires long-term maintenance treatment. Psychogenic depression generally has a better prognosis if the triggering factors are resolved and treatment is timely, with a lower risk of recurrence compared to endogenous depression—indicating differences in outcomes.

　　In daily life, maintain regular sleep patterns and a balanced diet, actively engage in social activities and moderate exercise, and avoid prolonged isolation. Offer understanding and support, minimize emotional stressors, help build positive thinking patterns, and assist in improving overall emotional well-being.
