Our aim was to compare the clinical features of panic disorder (PD) patients sensitive to hyperventilation or breath-holding methods of inducing panic attacks. Eighty-five PD patients were submitted to both a hyperventilation challenge test and a breath-holding test. They were asked to hyperventilate (30 breaths/min) for 4 min and a week later to hold their breath for as long as possible, four ...

In this study, patients with panic disorder (PD) who suffered nocturnal panic (NP) attacks were compared with PD patients who never experienced NP attacks and healthy controls. Three tasks were chosen to evaluate attention to cardiac cues, reactivity to induction of respiratory cues, and reactivity to relaxation cues. Relative to healthy controls, PD groups reported more fear of all three tasks...

BACKGROUND Panic disorder (PD) is common in the community and contributes to significant distress and decreased quality of life for people who suffer from it. Most people with PD will present in the first instance to their general practitioner or hospital emergency department for assistance, often with a focus on somatic symptoms and concerns. OBJECTIVE This article aims to assist the GP to m...

PURPOSE Recent neuroimaging findings have revealed that paralimbic and prefrontal regions are involved in panic disorder (PD). However, no imaging studies have compared differences in cortical thickness between patients with PD and healthy control (HC) subjects. MATERIALS AND METHODS Forty-seven right-handed patients with PD who met the diagnostic criteria in the Diagnostic and Statistical Ma...

In panic disorder (PD) and agoraphobia with panic attacks, periodic panic attacks occur, characterized by the sudden onset of such physical symptoms as paresthesia, dizziness, palpitations, etc and are accompanied by a sensation of extreme fear (1). Panic attacks may be provoked by using some probes. Procedures that provoke symptoms of a specific illness have obvious value as tools for the stud...

s | 7 elevated in patients with Panic Disorder (PD). The objective of this study is to investigate the White Matter (WM) correlates of anxiety sensitivity in PD. Methods: 112 right-handed patients with PD and 48 Healthy Control (HC) subjects were enrolled in this study. All patients were examined by means of magnetic resonance image at 3 Tesla. The Anxiety Sensitivity Inventory-Revised (ASI-R) ...

OBJECTIVE Findings showing that individuals with panic disorder (PD) are prone to experience panic attacks when inhaling CO2-enriched air have given rise to the hypothesis that physiological systems underlying the experience of suffocation may be important in the etiology of PD. In this study, we tested several predictions stemming from this view. METHODS Forty individuals with PD and 32 cont...

OBJECTIVE The primary objective of this study was to assess whether pentagastrin-induced panic symptoms are associated with release of free fatty acids (FFAs) in a manner that could explain the mechanism of correlations observed between serum cholesterol levels and frequency and severity of panic attacks in patients with panic disorder (PD). A secondary objective was to assess whether pretreatm...
