Recent findings in adolescent depression and suicide.

Adolescent depression and suicide are currently the focus of lively investigation. While diagnostic terminology and prevalence of depression remain unresolved, promising clarification is likely from the new assessment techniques readily available. These range from vigorous history taking and the use of questionnaires to biological tests. Associated depressive spectrum conditions are being defined. Like depression itself, they often respond to the new biological and psychological treatment methods of demonstrated effectiveness. Compounds are under development which may lessen side effects, and plasma antidepressant measurements are of proven value. Even with respect to adolescent suicidal behavior, where similar biological and psychological approaches have yielded less impressive results to date, energetic diagnosis and intervention can be lifesaving.
