Dissociative Identity Disorder CPAP Adherence: An Uncommon Factor in Obstructive Sleep Apnea.

We present a case of a patient with dissociative identity disorder and symptomatic sleep apnea who was treated with continuous positive airway pressure (CPAP). CPAP use depended upon which personality the patient exhibited but apnea reduction did not. This case illustrates in one individual how personality can positively or negatively affect CPAP adherence.

Frequency and impact of pulmonary hypertension in patients with obstructive sleep apnea syndrome.

The correlates and consequences of pulmonary hypertension (PH) associated with obstructive sleep apnea (OSA) are poorly understood. Patients undergoing pulmonary artery catheterization within 6 months of an overnight polysomnography showing OSA were included in the present analysis. A total of 83 patients with complete data were analyzed (no PH, n = 25 [30%]; PH, 58 [70%]; of these, 18 had a pulmonary capillary wedge pressure of <15 mm Hg).

Prevalence and characteristics of restless legs syndrome in patients with pulmonary hypertension.

Background: Patients with pulmonary hypertension (PH) have an increased prevalence of risk factors for restless legs syndrome (RLS). We performed a cross-sectional study to determine the prevalence and characteristics of RLS in this population.

Methods: Patients filled out two questionnaires during a visit: (1) a diagnostic tool for RLS, based on the core clinical features; and (2) a 10-question rating scale used to assess severity.
