Depression

Everyone experiences sadness at times. But depression is something more. Depression is extreme sadness or despair that lasts more than days. It interferes with the activities of daily life and can even cause physical pain. Fortunately, depression is highly treatable.

Depression, also known as major depressive disorder or clinical depression, is one of the most common mental disorders in the United States. In 2014, an estimated 15.7 million adults in the U.S. — about 6.7 percent of all U.S. adults — had at least one major depressive episode, according to the National Institute of Mental Health (NIMH).
