ABSTRACT One of the proposed revisions for DSM-5 is to rate panic attacks as a separate dimension across all mental disorders. The idea is that panic attacks occurring outside panic disorder are a dimension predicting important clinical outcomes. The aim of this study was to validate the proposition for DSM-5 that panic attacks have predictive value for overall psychopathology onset, course, and functioning.
Data were derived from the Netherlands Mental Health Survey and Incidence Study (NEMESIS), a prospective population-based study. Using the Composite International Diagnostic Interview (with classifications based on DSM-III-R), 5,571 subjects were selected who had (1) no panic history, (2) a history of panic attacks (but no panic disorder), (3) current panic attacks, or (4) current panic disorder. The impact of panic status on the prevalence of anxiety, affective, alcohol, and any mental disorders; on the onset and persistence of these disorders during 3-year follow-up; and on levels of functioning during 3-year follow-up (as assessed with the 36-Item Short-Form Health Survey) was examined.
Current panic attacks outside the realm of panic disorder were associated with increased prevalence of mental disorders (χ23 = 490.6; P < .001), increased onset of mental disorders (hazard ratio = 4.42; 95% CI, 2.88-6.80), persistence of mental disorders (odds ratio = 2.72; 95% CI, 1.53-4.82), and impaired functioning during 3-year follow-up (F = 69.67; P < .001). Although the impact was smaller than for panic disorder, the associations identified for panic attacks were consistent and significant and were, to a lesser extent, also found for a history of panic attacks.
Given the consistent impact of panic attacks on various aspects of psychopathology, the proposition to dimensionally rate panic attacks across all mental disorders may be of great value for clinical care.

    ABSTRACT: Although fearful spells (FS) and panic attacks (PA) increase the risk for various mental disorders, few studies have examined whether help-seeking in those with FS/PA attenuates the risk for incident psychopathology.

    ABSTRACT: Background Panic attacks (PAs) are common in many psychiatric disorders other than panic disorder, especially social anxiety disorder (SAD). PAs have been associated with increased severity, comorbidity, and impairment in many disorders; therefore, PAs can now be used as a descriptive specifier across all DSM-5 disorders. However, the clinical implications of PAs in SAD remain unclear. Methods The aim of the present investigation was to examine demographic and clinical characteristics associated with SAD-related situational panic attacks in a large, representative epidemiological sample of individuals with SAD (N=1138). We compared individuals with SAD who did and did not endorse situational PAs in terms of demographic factors, fear/avoidance of social situations, distress, impairment, and diagnostic comorbidity. Results Being male, black, Asian, or over 65 years old was associated with a decreased likelihood of experiencing situational PAs, whereas being unemployed was associated with an increased likelihood. Individuals with situational PAs also exhibited greater fear and avoidance of social situations, impairment, coping-oriented substance use, treatment utilization, and concurrent and longitudinal psychiatric comorbidity. Limitations Consistent with most epidemiologic studies, the information collected relied on self-report, and not all participants were available for both waves of assessment. Conclusions The present findings suggest that SAD-related situational PAs are associated with more severe and complex presentations of SAD. Implications for the assessment and treatment of SAD, as well as for the use of PAs as a descriptive specifier for SAD, are discussed.

    ABSTRACT: The occurrence of panic symptoms in various anxiety disorders has been associated with more severely impaired and difficul-to-treat cases, but this has not been investigated in dental phobia. We examined the clinical implications of panic symptoms related to sub-clinical and clinically significant dental phobia. The sample consisted of 61 patients at a university dental clinic who endorsed symptoms of dental phobia, 25 of whom met criteria for a formal diagnosis of dental phobia. Participants with dental phobia endorsed more panic symptoms than did those with sub-clinical dental phobia. In the total sample, greater endorsement of panic symptoms was associated with higher dental anxiety, more avoidance of dental procedures, and poorer oral health-related quality of life. Among those with dental phobia, certain panic symptoms exhibited associations with specific anxiety-eliciting dental procedures. Panic symptoms may serve as indicators of clinically significant dental phobia and the need for augmented treatment.
