Separation anxiety disorder

Overview


Plain-Language Overview

Separation anxiety disorder is a condition that affects the brain and emotions, causing intense fear or distress when a person is away from someone they feel attached to, usually a parent or caregiver. It mainly impacts children but can also occur in adults. This disorder involves the nervous system and emotional regulation, leading to symptoms like excessive worry about harm coming to loved ones or being lost. People with this condition may experience physical symptoms such as headaches or stomachaches when separated. The disorder can interfere with daily activities like school or work and affect social relationships. Understanding this condition helps explain why some individuals have strong emotional reactions to separation.

Clinical Definition

Separation anxiety disorder is a psychiatric condition characterized by excessive and developmentally inappropriate fear or anxiety concerning separation from attachment figures. It involves dysregulation of the limbic system and hypothalamic-pituitary-adrenal axis, leading to heightened stress responses. The disorder typically arises from a combination of genetic predisposition, environmental stressors, and early attachment disruptions. Clinically, it presents with persistent worry about losing major attachment figures, reluctance or refusal to be alone, and somatic complaints during separation. It is significant because it can impair social, academic, and occupational functioning and increase risk for other anxiety disorders. Diagnosis requires symptoms lasting at least 4 weeks in children and 6 months in adults, with marked distress or impairment.
