Evidence for respiratory and nonrespiratory subtypes in panic disorder.

摘要: Recently researchers have posited a “respiratory” subtype of panic disorder (PD), which differs from “nonrespiratory” subtypes in phenomenology and perhaps treatment response. This study was designed to further examine evidence for the existence respiratory PD. Individuals with PD prominent symptoms (PD-R; n=10) without (PD-NR; n=23), as well healthy controls (n=27), underwent standardized 5% CO2 rebreathing challenge. Ventilatory response subjective sensation suffocation were continuously recorded. The PD-R group exhibited greater levels, rates respiration, propensity terminate procedure voluntarily than did other two groups, turn not differ on these measures. Findings are consistent PD, nonrespiratory sensitivity. Depression Anxiety 23:474–481, 2006. Published 2006 Wiley-Liss, Inc.
