Historical Background

Anxiety as a clinical concept was first systematically described by Sigmund Freud in the 1890s, who distinguished "anxiety neurosis" from other nervous conditions. The modern classification of anxiety disorders began with the DSM-III in 1980, which separated anxiety into distinct categories including panic disorder, generalized anxiety disorder, and phobias.
