Neurocognitive functioning in comorbid insomnia and sleep apnea patients is better after positive airway pressure therapy, but worse after cognitive behavioral therapy for insomnia: exploratory analysis of cognitive outcomes from the Multidisciplinary Approach to the Treatment of Insomnia and Comorbid Sleep Apnea study.

Study Objectives: Neurocognitive impairments in comorbid insomnia and sleep apnea (COMISA) are not well documented. We explored neurocognitive functioning and treatment effects in individuals with COMISA as an ancillary study to a randomized clinical trial.

Methods: Participants with COMISA (n = 45; 51.

A randomized controlled trial of cognitive behavioral therapy for insomnia and PAP for obstructive sleep apnea and comorbid insomnia: effects on nocturnal sleep and daytime performance.

Study Objectives: This study examines the impact of cognitive behavioral therapy for insomnia (CBT-I) and positive airway pressure (PAP) therapy for comorbid insomnia and sleep apnea on nocturnal sleep and daytime functioning.

Methods: A partial factorial design was used to examine treatment pathways with CBT-I and PAP and the relative benefits of each treatment. One hundred eighteen individuals with comorbid insomnia and sleep apnea were randomized to receive CBT-I followed by PAP, self-monitoring followed by CBT-I concurrent with PAP, or self-monitoring followed by PAP only.

Attentional Bias Assessed With Event-Related Potentials in Long-term Hypnotic Users.

Purpose/background: Attentional bias toward drug-related cues is considered to be an indication of neurocognitive processes associated with drug dependence. While this phenomenon has been shown in other addictive substances, whether hypnotic medication would lead to similar processes remains an issue to be investigated. The present study examined attentional bias toward drug-related cues in long-term hypnotic users and the effect of negative affect on this process.
