Panic disorder and the respiratory system: clinical subtype and challenge tests.
INTRODUCTION Respiratory changes are associated with anxiety disorders, particularly panic disorder (PD). The stimulation of respiration in PD patients during panic attacks is well documented in the literature, and a number of abnormalities in respiration, such as enhanced CO2 sensitivity, have been detected in PD patients. Investigators hypothesized that there is a fundamental abnormality in t...
متن کاملClinical Characteristics of the Respiratory Subtype in Panic Disorder Patients
OBJECTIVE Panic disorder has been suggested to be divided into the respiratory and non-respiratory subtypes in terms of its clinical presentations. The present study aimed to investigate whether there are any differences in treatment response and clinical characteristics between the respiratory and non-respiratory subtypes of panic disorder patients. METHODS Among the 48 patients those who co...
متن کاملClonidine in respiratory panic disorder subtype.
OBJECTIVE Clonidine, which inhibits locus coeruleus discharge, would seem for theoretical reasons to be a good antipanic drug. Panic disorder (PD) presents a heterogeneous cluster of symptoms and a classification based on subtypes has been suggested and the respiratory symptoms group appears as a distinct subtype. METHOD We report three cases of respiratory PD patients who were successfully t...
متن کاملRespiratory panic disorder subtype and sensitivity to the carbon dioxide challenge test.
The aim of the present study was to verify the sensitivity to the carbon dioxide (CO2) challenge test of panic disorder (PD) patients with respiratory and nonrespiratory subtypes of the disorder. Our hypothesis is that the respiratory subtype is more sensitive to 35% CO2. Twenty-seven PD subjects with or without agoraphobia were classified into respiratory and nonrespiratory subtypes on the bas...
متن کاملThe panic disorder respiratory ratio: a dimensional approach to the respiratory subtype.
OBJECTIVE The respiratory ratio is a dimensional construct of the respiratory subtype of panic disorder (PD). The respiratory subtype has been correlated with an increased sensitivity to CO₂ inhalation, positive family history of PD and low comorbidity with depression. The objective of our study was to determine whether the respiratory ratio is correlated with CO₂-induced panic attacks and othe...
