BACKGROUND Panic attacks are common, and while they are not life-threatening events, they can lead to the development of panic disorder and agoraphobia. Appropriate help at the time that a panic attack occurs may decrease the fear associated with the attack and reduce the risk of developing an anxiety disorder. However, few people have the knowledge and skills required to assist. Simple first a...

Anxiety sensitivity is a known precursor to panic attacks and panic disorder, and involves the misinterpretation of anxiety-related sensations. Aerobic exercise has been shown to reduce generalized anxiety, and may also reduce anxiety sensitivity through exposure to feared physiological sensations. Accordingly, 54 participants with elevated anxiety sensitivity scores completed six 20-min treadm...

Our objective was to explore the dose-response relationship in patients with panic disorder and social anxiety disorder comorbidity (DSM-IV). After 1 week of no-drug washout, 36 such patients were assigned to a double-blind controlled comparison of the effects of 30 mg and 60 mg of tranylcypromine, and were followed up for 12 weeks. The main instrument used to measure the number of panic attack...

The current study investigated the main and interactive effects of a nonclinical panic attack history and distress tolerance in relation to PTSD symptoms. The sample consisted of 91 adults (62.6% women; M(age)=23.45, SD=9.56) who met DSM-IV criteria for trauma exposure, 53.8% of whom met criteria for a recent (past 2 years) history of nonclinical panic attacks. Results indicated that distress t...

This study compared Panic Online (PO), an internet-based CBT intervention, to best-practice face-to-face CBT for people with panic disorder with or without agoraphobia. Eighty-six people with a primary diagnosis of panic disorder were recruited from Victoria, Australia. Participants were randomly assigned to either PO (n=46) or best practice face-to-face CBT (n=40). Effects of the internet-base...

OBJECTIVE The purpose of this study was to estimate the general population incidence of late-life agoraphobia and to define its clinical characteristics and risk factors. METHOD A total of 1,968 persons ≥65 years old were randomly recruited from the electoral rolls of the district of Montpellier, France. Prevalent and incident agoraphobia diagnosed with a standardized psychiatric examination ...

OBJECTIVE Previous findings of excess brain lactate and delayed end-tidal CO(2) (pCO(2)) recovery in subjects with panic disorder during hyperventilation suggested altered acid-base regulation. Two models were posited to explain these results: 1) subjects with panic disorder demonstrate greater alkalosis to hyperventilation, implicating increased lactate as directly compensatory, or 2) subjects...

A dimensional and psychometrically informed taxonomy of anxiety is emerging, but the specific and nonspecific dimensions of panic and phobic anxiety require greater clarification. In this study, confirmatory factor analyses of data from a sample of 438 college students were used to validate a model of panic and phobic anxiety with six content factors; multiple scales from self-report measures w...

OBJECTIVE Panic disorder is characterized by recurrent panic attacks, persistent concerns about additional attacks, and worry about the implications of the attack or significant changes in behavior related to the attacks. We examined the efficacy of 24-week naturalistic, open-label escitalopram treatment in terms of the response and remission rates and functional disability in 119 adult Korean ...

We examined mediational models of panic-fear, panic disorder (PD), and asthma outcomes among adult asthma patients. PD was assessed by the Anxiety Disorders Interview Schedule. Twenty-one asthma-PD patients and 27 asthma-only patients completed spirometry and questionnaires. Asthma-PD patients reported greater illness-specific and generalized panic-fear than asthma-only patients, despite no dif...
