Aging and panic disorder: phenomenology, comorbidity, and risk factors.
OBJECTIVE
The authors compared young and older adults with panic disorder (PD) to investigate differences in panic-associated phenomenology, psychiatric comorbidity, and risk factors.


METHODS
Patients in the older group (age 60 and above) were further subdivided into early- and late-onset groups and compared. Phenomenology (number of panic symptoms, severity of anxiety, physiological symptoms, panic-associated cognitions, and overall severity of PD); comorbidity (depressive and anxiety disorders); and risk factors (family history of anxiety and life stressors) were assessed in 167 outpatients with PD.


RESULTS
Older patients reported fewer panic symptoms, less anxiety and arousal, less severe PD, lower levels of depression, and higher levels of functioning. Furthermore, within the older-patient group, late-onset patients were found to report less distress during panic attacks in relation to body sensations and panic-related cognitions and emotions. Multiple-regression analysis of the entire sample showed that chronological age and age at onset of PD distinctly predicted different domains of panic phenomenology.


CONCLUSIONS
PD was consistently less severe in older patients across multiple domains, and a later age at onset was associated with less distress due to body sensations, cognitions, and emotions during panic attacks.
