title: Dyspneic-fear and catastrophic cognitions in hyperventilatory panic attacks.
abstract: The tenability of cognitive explanations of the experience of fear during panic attacks (viz. Ley's misattribution-of-symptoms hypothesis and Beck's and Clark's catastrophic-misinterpretation-of-symptoms hypotheses) is seriously questioned by findings from three independent lines of research: (a) Wolpe and Rowan's observation that catastrophic cognitions follow fear, (b) Rachman, Levitt and Lopatka's reports of panic attacks without fearful cognitions, and (c) reports of panic attacks during sleep occurring predominately during non-dreaming stages of sleep. Recognition of these findings led Ley to reject his misattribution-of-symptoms hypothesis in favor of an innate emotional-respiratory-response explanation. The revised hyperventilation theory now maintains that fear experienced during a hyperventilatory panic attack is caused by severe dyspnea in the context of little or no perceived control over the causes of the dyspnea (i.e. dyspneic-fear). Cognitions during panic attacks are discussed in terms of the cognitive deficit that results from the cerebral hypoxia produced by hyperventilation. Implications for theory and treatment are discussed.
