Medical evaluation of panic attacks.

Panic disorder with or without agoraphobia is dominated by the occurrence of panic attacks. However, panic attacks are also reported to occur as part of the clinical picture in several medical conditions, notably thyroid disease, hypoglycemia, and pheochromocytoma. The authors examine these conditions, review the relevant literature, and offer an evaluation strategy. Routine screening is not recommended. Panic disorder is also associated with mitral-valve prolapse and temporal lobe seizures. The authors explore the possible consequences of this association and outline an evaluation strategy. Again, routine screening is not recommended.
