PANIC ATTACKS AND RELATED DISORDERS IN ALCOHOL-DEPENDENT, DEPRESSED, AND NONCLINICAL SAMPLES

Although several studies have indicated that a substantial portion of alcoholics have an anxiety disorder, relatively little information exists specifically regarding panic disorders. In addition, prior studies have been marred by the absence of appropriate contrast groups. The present investigation compared the lifetime prevalence of panic attacks and panic-related disorders diagnosed according to DSM-III criteria in a group of 79 alcohol-dependent patients, 64 depressed patients, and 70 nonclinical subjects. Panic attacks, panic disorder, and agoraphobia with panic attacks were more prevalent in the alcohol-dependent and depressed samples than among nonclinical subjects. Men in both clinical samples were more likely than women to have had nonagoraphobic panic disorder, but male alcoholics were less likely to have developed agoraphobia than were female alcoholics or depressed patients of either sex. No consistent chronological relationship between onset of panic attacks and alcohol abuse was found. Results indicate that there is an unusually high prevalence of panic attacks and panic-related disorders among alcoholics, but comparable prevalence rates can be found in depressed and perhaps some other psychiatric populations. Implications for the assessment and treatment of alcohol-dependent and panic-disordered patients are discussed. © 1990 by William & Wilkins.
