Separation Anxiety Disorder is a DSM-5 anxiety disorder marked by developmentally excessive fear or distress about separation from major attachment figures, persisting at least six months in adults. Core features include recurrent worry about losing or being apart from loved ones, refusal to be alone or to leave home, nightmares about separation, and physical complaints (headache, nausea, stomach upset) when separation occurs or is anticipated. Once considered a childhood condition, DSM-5 recognizes that it can onset in or persist into adulthood, often co-occurring with other anxiety, panic, and depressive disorders.
