Depression is a state of sadness and loss of interest in activities. It can affect a person's thoughts, behavior, feelings, sleep, appetite, and sense of well-being. Symptoms such as pain and digestive problems without a clear underlying cause may occur. Complications may include suicide.

The cause is believed to involve both genetic and environmental factors. A family history of the condition increases the risk about 3 fold. It occurs as part of a number of mental disorders including major depression, persistent depressive disorder, seasonal affective disorder, post partum depression, and premenstrual dysphoric disorder. It may also occur as a side effect of medication, from substance misuse, or as a result of a medical condition such as cancer, stroke, or chronic pain. Episodes may be triggered by the death of a loved one, financial problems, or relationship issues.

Diagnosis is based on symptoms and examination. By definition symptoms must be present every day, nearly all day, for at least two weeks. Blood tests and medical imaging may be done to rule out an underlying medical cause. Conditions that may present similarly include sadness.

Treatment may involve counselling and medication. Hospitalization may be required in those at risk of suicide. Electroconvulsive therapy may be done in those who do not respond to other measures. Relapses are common after treatment. Depression is common. In a given year about 7% of people experience major depression. Young adults are more commonly affected as are females.
