We refer to mental disorders using different “umbrella” terms such as emotional disturbance, behavioral disorders, or mental illness. Beneath these umbrella terms, there is actually a wide range of specific conditions that differ from one another in their characteristics and treatment. These include (but are not limited to): • anxiety disorders; • bipolar disorder (sometimes called manic-depression); • conduct disorders; • eating disorders; • obsessive-compulsive disorder (OCD); and • psychotic disorders
