Understanding Depression

Course overview

The evidence shows that depression is a common mental illness. Major depressive disorder probably involves a complex interplay between biology, genetics, environment, and personality. Basically, a person is born susceptible to having a major depressive disorder, and the condition develops as the person is exposed to specific risk factors. Depending on the clinical picture, major depressive disorder is categorized as mild, moderate, or severe. Major depression can be incapacitating. Screening for depression should be a part of routine health care. Pharmacotherapy and psychotherapy are the mainstays of treatment for a major depressive disorder, however depression can be very difficult to treat. Antidepressants and psychotherapy may not be enough to reduce depressive signs and symptoms. Alternative therapies and self-help can be helpful additions to the patient's treatment plan that can make a major difference in progress.
