Frommberger and colleagues describe a well-designed study that supports the principal conclusion of our study, ie, specific psychiatric diagnoses need to be included in the differential diagnosis of the dizzy patient. Another study, by Kroenke et al1 has similarly found that psychiatric disorders are among the most common causes of persistent dizziness in an ambulatory medical population. The findings of Frommberger et al concerning the power of autonomic and psychiatric symptoms to differentiate between panic disorder and neurological disease are compatible with findings that we have reported elsewhere.2 The findings of Frommberger et al differ from ours in that they found a greater prevalence of panic disorder than of major depression. This could be due to the differences between their neurology setting and our otolaryngology setting.
