The necessity, validity, and clinical utility of a new diagnostic entity: Acute suicidal affective disturbance.

ABSTRACT

OBJECTIVE: Here we argue for the necessity, validity, and clinical utility of a new diagnostic entity, acute suicidal affective disturbance (ASAD). METHOD: We expand on the conceptual, clinical, and practical rationale for ASAD, propose its defining features, describe research results to date, and suggest avenues for future research. RESULTS: There is accruing evidence for the existence of a previously unclassified, rapid-onset mood disturbance that geometrically escalates and regularly results in life-threatening behavior. CONCLUSIONS: ASAD research may not only improve the field's understanding of suicidal behavior but also enhance clinical effectiveness and save lives.
