Depression is a serious and common mood disorder. Signs and symptoms include feelings of hopelessness or pessimism; irritability; decreased energy or fatigue; loss of interest or pleasure in hobbies and activities; difficulty concentrating, remembering, or making decisions; and feelings of guilt, worthlessness, or helplessness.
Major depression is typically treated with medications, psychotherapy, or a combination. Although antidepressants are the most commonly prescribed class of medications in the U.S., some studies have found that many adults with depression don’t receive treatment.
