    Depression: Depression Glossary


    Body dysmorphic disorder: Excessive concern with imagined or exaggerated problems in one's appearance.

    Bulimia nervosa: An eating disorder in which people eat large amounts of food at one time (binge) while feeling no sense of control over the amount they're eating, and then make themselves vomit (purge) or use other methods to try to lose weight, such as excessive exercise, fasting, or abuse of laxatives or diuretics. In order to be diagnosed with bulimia, this behavior must occur at least once a week for three months in a row.

    Chemical dependency counselors: Health care professionals trained especially to help people with alcohol and drug addiction through the process of recovery. They must hold either an associate's or bachelor's degree, and may also have a master's degree in counseling.

    Clinical social workers: Trained health care personnel who hold a master's or doctoral degree in social work. They may provide psychotherapy, case management, and a variety of supportive assistance. One function is often to help patients transition from a hospital or medical institution to home.

    Conduct disorder: Disruptive behavior in children marked by repetitive, severe and persistent violation of the rights of others or of age-appropriate social norms or rules. For example, children with conduct disorder are more likely to bully others, disregard parent curfews, and use alcohol and other substances.

    Depression: A clinical mood disorder associated with low mood or loss of interest in activities a person once enjoyed and other symptoms that prevent a person from leading a normal life. Types of depression include: major depression, bipolar depression, persistent depressive disorder (including dysthymia and chronic major depression) and depressive disorder with seasonal pattern (formerly called seasonal affective disorder or SAD).

    Depressive Disorder with Seasonal Pattern, formerly called seasonal affective disorder (SAD), is a subtype of major depressive disorder that recurs each year at the same time, usually starting in fall or winter and ending in spring or early summer. It is more than just "the winter blues" or "cabin fever." A rare form of depressive disorder with seasonal pattern, known as "summer depression," begins in late spring or early summer and ends in fall.
