Causes

Depression is a complex disease. Genetics, biology, environment, and psychology all play a part. The exact cause is not known, but it is likely a combination of many factors.

Treatment

Depression is treatable. The first step is to visit a doctor or mental health specialist. They can diagnose you, provide treatment, or refer you to a mental health professional. Treatment options include psychotherapy (talk therapy), medications, and brain stimulation therapies.
