BACKGROUND We examined prospectively determined bidirectional associations between smoking and panic and other anxiety disorders and their temporal ordering of onset in a representative community sample of adolescents and young adults. METHODS Baseline and 4-year follow-up data were used from the Early Developmental Stages of Psychopathology Study, a prospective longitudinal study of adolesce...

As listed in the DSM-IV-TR, the essential features of panic disorder are "the presence of recurrent, unexpected Panic Attacks, followed by at least 1 month of persistent concern ... or a significant behavioral change related to the attacks" (American Psychiatric Association, 2000). Panic disorder is characterized by instances of an intense sense of impending doom in which many patients will fee...

OBJECTIVE The authors examined the distribution of catechol O-methyltransferase (COMT) genotypes in patients with panic disorder as well as the relationship between a COMT polymorphism and the clinical characteristics of these patients. METHOD Fifty-one patients with panic disorder and 45 healthy comparison subjects were tested for a genetic polymorphism of COMT. Clinical variables were asses...

BACKGROUND The purpose of this systematic review was to identify characteristics of the chest pain associated with the presence of panic disorder, to determine the strength of the association between panic disorder and coronary artery disease (CAD), and to determine the association between panic disorder and known cardiovascular risk factors. METHODS Potential studies were identified via comp...

PANIC DISORDER IS THE MOST COMMON TYPE OF ANXIETY DISORDER, AND ITS MOST COMMON EXPRESSION IS PANIC ATTACKS CHARACTERIZED WITH SUDDEN ATTACKS OF ANXIETY WITH NUMEROUS SYMPTOMS, INCLUDING PALPITATIONS, TACHYCARDIA, TACHYPNEA, NAUSEA, AND VERTIGO: ie, cardiovascular, gastroenterologic, respiratory, and neuro-otologic symptoms. In clinical practice, panic disorder manifests with isolated gastroent...

Intravenous sodium lactate infusions or the noradrenergic agent yohimbine reliably induce panic attacks in humans with panic disorder but not in healthy controls. However, the exact mechanism of lactate eliciting a panic attack is still unknown. In rats with chronic disruption of GABA-mediated inhibition in the dorsomedial hypothalamus (DMH), achieved by chronic microinfusion of the glutamic ac...

Panic disorder is a common psychiatric disorder characterized by recurrent anxiety attacks and anticipatory anxiety. Due to the severity of the symptoms of the panic attacks and the frequent additional occurrence of agoraphobia, panic disorder is an often debilitating disease. Elevation of central serotonin levels by drugs such as clomipramine represents one of the most effective treatment opti...

BACKGROUND We have previously reported that 35% CO2 challenge induced myocardial ischemia in 81% of coronary artery disease (CAD) patients with comorbid panic disorder (PD) and previous positive nuclear exercise stress tests. However, it is yet unclear whether this is the case among CAD patients with PD and normal nuclear exercise stress test results. We hypothesized that a potent mental stress...

The present study compared learning processes associated with panic-related symptoms in families with and without panic disordered mothers. Using a multi-informant approach, 86 mothers [of whom 58 had a primary diagnosis of panic disorder (PD)], their partners and teenage children (mean age, 16.67 years) reported about parents' behavior (modeling and operant learning) in response to children's ...
