Summary
Obstructive sleep apnea (OSA) is commonly reported in Veterans with post-traumatic stress disorder, which can potentiate symptoms of anxiety and depression, daytime symptoms and worsen nightmares. Continuous positive airway pressure (CPAP) is the most effective therapy but adherence to treatment is suboptimal. Insomnia is considered a barrier to long-term adherence. The overarching theme of the proposal is to compare the effectiveness of cognitive behavioral therapy for insomnia (CBT) plus eszopiclone, a nonbenzodiazepine hypnotic, versus CBT alone in Veterans with PTSD who are diagnosed with both OSA and insomnia, using a randomized, clinical trial, on sleep quality of life, PTSD severity, and CPAP adherence.
