What is depression?
Depression is a treatable mental-health condition involving persistent low mood or loss of interest that can affect thinking, body and daily life.
Causes, symptoms and diagnosis
1. Definition and causes Life events, health, biology and social factors can combine. Depression is not a personal weakness or simple lack of motivation. 2. Symptoms and assessment Sleep, appetite, energy, concentration, guilt or hope may change. A professional reviews duration, function, medicines and possible medical causes; online tests are not diagnoses. 3. Care and treatment Talking therapies, support and sometimes medication are options. Decisions reflect severity, preference and health; medicines should not be started or stopped independently.
Warning signs and prevention
4. When to seek help Thoughts of self-harm, inability to stay safe or severe loss of function require urgent help. Involving a trusted person can support immediate safety. 5. Prevention and daily life Sleep and activity can support treatment but may not resolve severe depression alone. Early follow-up helps if symptoms return.
