Our ancestors without fear, worry and anxiety are not our ancestors, as organisms without defense systems were extinct. Therefore, while behavior such as fear and anxiety are useful to prevent harm, the exaggerated form, that is, anxiety disorders, has more costs than benefits. Likewise, while a panic attack is a normal and useful response in the face of life-threatening danger, a panic disorde...

Research has shown that emotional avoidance and anxiety sensitivity are associated with more self-reported fear and distress in response to laboratory fear challenge procedures. The present study aimed to expand upon this work and examined how emotional avoidance and anxiety sensitivity are related to emotional and physiological responses to an observational fear challenge procedure. To accompl...

Discomfort intolerance, defined as an individual difference in the capacity to tolerate unpleasant bodily sensations, is a construct recently posited as a risk factor for panic and anxiety psychopathology. The present report used a biological challenge procedure to evaluate whether discomfort intolerance predicts fearful responding beyond the effects of trait anxiety and a well-established psyc...

The effect of ambient air pollution on panic disorder in the general population has not yet been thoroughly elucidated, although the occurrence of panic disorder in workers exposed to organic solvents has been reported previously. We investigated the association of ambient air pollution with the risk of panic attack-related emergency department visits. Using health insurance claims, we collecte...

In a sample of 131 patients with panic disorder, we explored both the presence of DSM-III-R criteria for hypochondriasis and the occurrence of illness phobia before the onset of panic disorder. To explore further the possible relationship between hypochondriacal features and panic-agoraphobic syndrome, we compared patients both with and without current hypochondriasis and then patients both wit...
