Anxiety separation disorder (SAD) became the subject of increased attention of researchers in recent decades. DSM-5 and project of ICD-11 allow us to treat this disorder as an independent nosological unit without attachment to age. The review provides information on the prevalence, clinical manifestations and diagnosis of SAD in adults, summarizes information on the etiopathogenesis, relations to other psychiatric disorders, and highlights the lack of modern therapeutic approaches to SAD. The purpose of this review is to raise the level of knowledge about SAD and its new positioning in classification systems.
