Other Anxiety Disorders in the DSM-5

The anxiety disorders described on this site derive from an earlier classification of anxiety disorders presented in DSM-IV. This section of the site has been revised to be compatible with the newer DSM-5 classification of anxiety disorders, released in 2013.

Two additional anxiety disorders, which were added to DSM-IV, were retained in DSM-5: Anxiety Disorder Due to Another Medical Condition and Substance/Medication-Induced Anxiety Disorder. They are described below. Acute Stress Disorder, which was listed under additional anxiety disorders in DSM-IV, was regrouped and listed under Trauma and Stressor Related Disorders in DSM-5 (see the appropriate section under the Anxiety Disorders menu on this website). One final condition, Agoraphobia Without a History of Panic Disorder, was eliminated from DSM-5. If someone just has agoraphobia without panic attacks, the current practice is to assign only the diagnosis of agoraphobia. If a person has both agoraphobia and panic attacks, the current practice is to assign them a dual-diagnosis of both agoraphobia as well as panic disorder.

Anxiety Disorder Due to Another Medical Condition

This diagnostic category is reserved for situations in which significant anxiety (in the form of either panic attacks or generalized anxiety) is a direct physiological effect of a specific medical condition. Numerous types of medical conditions can cause anxiety, including endocrine conditions (hyper- and hypothyroidism, pheochromocytoma, hypoglycemia), cardiovascular conditions (congestive heart failure, pulmonary embolism), metabolic conditions (vitamin B12 deficiency or iron deficiency) and neurological conditions ( for example, vestibular problems or encephalitis).

Substance/Medication-Induced Anxiety Disorder

This category is used when generalized anxiety or panic attacks are determined to be the direct physiological effect of a substance, whether a drug of abuse, a medication, or toxin exposure. The anxiety may be a result either of exposure to the substance or of withdrawal from it. For example, if you had no previous history of an anxiety disorder, then suddenly developed panic attacks as a result of withdrawing too quickly from a medication, you would receive this diagnosis.
