A. Generalized Anxiety Disorder. Anxiety is more constant than in panic disorder. Panic disorder is characterized by discrete episodes of severe anxiety along with physiologic symptoms.

B. Substance-Induced Anxiety Disorder. Amphetamines, cocaine or caffeine can mimic panic attacks. Physiologic withdrawal from alcohol, benzodiazepines or barbiturates can also precipitate panic attacks.

C. Anxiety Due to a General Medical Condition. Pheochromocytoma may mimic panic disorder and is characterized by markedly elevated blood pressure during the episodes of anxiety. It is excluded by a 24-hour urine assay for metanephrine or by serum catecholamines. Other medical conditions such as cardiac arrhythmias, hyperthyroidism, pulmonary embolism and hypoxia can present with symptoms similar to panic attacks.
