Introduction: Delivering cognitive behavioral therapy for insomnia over the internet bears the advantage of accessibility and uptake to many patients suffering from chronic insomnia. In the current study, we aimed to investigate the effectiveness of internet-based cognitive behavioral therapy for insomnia (iCBT-I) in routine care.

Materials And Methods: We conducted a two-arm non-blinded randomized controlled trial with care as usual (CAU) as a control condition.

Understanding which factors predict the outcome of internet-based cognitive behavioral therapy for insomnia (iCBT-I) may help to tailor this intervention to the patient's needs. We have conducted a secondary analysis of a randomized, controlled trial comparing a multicomponent iCBT-I (MCT) and an online sleep restriction therapy (SRT) for 83 chronic insomnia patients. The difference in the Insomnia Severity Index from pre- to post-treatment and from pre-treatment to follow-up at 6 months after treatment was the dependent variable.

Predictors, mediators, and moderators of treatment effect remain uncertain since previous studies often give contradictory results.

In the article authors discuss the current data on sleep changes with aging focusing on the influence of age-related degenerative changes in orexin-containing and pacemaker brain areas. Pathophysiological mechanisms of sleep disturbances in Parkinson's and Alzheimer's diseases have much in common with normal age neurophysiological changes. Maintenance of the sleep-promoting systems function could positively modify the course of these diseases.
