Separation Anxiety Disorder

Overview

Description

Separation Anxiety Disorder (SAD) is characterized by developmentally inappropriate and excessive fear or anxiety concerning separation from those to whom the individual is attached. The anxiety is persistent (lasting at least 4 weeks in children/adolescents and typically 6 months or more in adults) and causes clinically significant distress or impairment in social, academic, occupational, or other important areas of functioning.

Prevalence

Estimated 4% in children, 1.6% in adolescents, and ~0.9–1.9% in adults. Slightly more common in females.

Age of Onset

Most common onset in childhood (7–9 years), but can emerge in adolescence or adulthood, often after a stressor such as illness, relocation, or relationship loss.
