Depression is a medical condition that can cause a wide variety
of psychological and physical symptoms. It is estimated that
between 4 and 8 percent of adolescents are depressed. However,
depression in adolescents is probably underdiagnosed because the
symptoms can be difficult to recognize. Extreme and enduring
sadness is the best-known symptom of depression, although
adolescents can have a number of other symptoms, including
irritability, difficulty at school, changes in sleep habits,
and/or feelings of worthlessness. Depression is different than
occasional blues and grief because depression is persistent and
often interferes with the teen's ability to get along with
parents and friends, complete school work, and appropriately
participate in other normal daily activities. Depression is a
treatable condition. Psychotherapy (counseling), drug therapy,
and other measures can alleviate symptoms and help the
adolescent to succeed in school, develop and maintain healthy
relationships, and feel more self-confident
