It has been a relatively short time between clinical use of the term anxiety neurosis-which included worry, panic, and obsessions-and the advent of recent DSM-defined categorical diagnoses of panic disorder, generalized anxiety disorder, social anxiety disorder, posttraumatic stress disorder, and obsessive-compulsive disorder. It seems that we have moved from a symptom-oriented approach in treating anxiety to a syndromal approach in which the patient has to accumulate enough symptoms and impairment to have a more definable illness or disorder.
