Insomnia

On this page, we summarize our current research projects on the topic of Insomnia. We specifically investigate:

  • Neurophysiological and neuroimaging biomarkers of chronic insomnia and its treatments.

Benzodiazepines

Assessing The Effects Of Cognitive Behavioral Therapy On Sleep And Cognitive Functions After A Structured Withdrawal From Benzodiazepines In The Elderly

Summary

Chronic insomnia is a prevalent condition in the aging population, affecting almost a third of individuals aged 65 years or older. A certain class of medication called benzodiazepines are commonly used to treat this disorder. Their chronic use, however, is believed to have adverse effects on physical, mental and cognitive health, especially in the elderly. Weaning off this medication can be challenging. Cognitive Behavioral Therapy for Insomnia (CBT-I) is a psychological intervention that has been shown to improve sleep quality in a majority of insomniacs and has also been demonstrated to facilitate the withdrawal success from benzodiazepines. In this study, we will evaluate whether adding CBT-I along with a structured withdrawal from benzodiazepines will lead to better sleep and cognitive outcomes as compared to a withdrawal without CBT-I.

Insomnia

Insomnia Symptoms In Later Life And The Relationship With Cognitive Function

Summary

The Canadian Longitudinal Study on Aging (CLSA) is a large, national, long-term study that will follow approximately 50,000 men and women who are between the ages of 45 and 85 for at least 20 years. This project will analyse information regarding self-reported medical, psychological and sleep characteristics, in addition to cognitive performance measures collected from 30,000 CLSA participants. The project aims to determine whether changes in sleep characteristics or insomnia symptoms are directly related to cognitive function in older adults.

Sleep apnea

APNex: A Pilot Randomized Trial Of Combined Cognitive-Behavioural Therapy & Exercise Training Versus Exercise Training Alone For The Treatment of Chronic Insomnia In Obstructive Sleep Apnea

Summary

Prevalence rates for sleep apnea syndrome (SAS) are reported to range from 10% to 40% in the general population. The most prescribed therapy, positive airway pressure, which has proven efficacy, has an adherence rate of about 50% and was expensive. In addition, recent studies suggest that about 40 – 60% of patients with diagnosed SAS also report insomnia symptoms. This association has raised the possibility that comorbid insomnia or sleep disruption may have an important negative impact on the success of obstructive sleep apnea treatment. In this context, new alternative therapies must be studied, in particular in the patients suffering from both SAS and insomnia. In this view, the goal of this work is to study cognitive-behavioral therapy and exercise training intervention among insomnia patients with comorbid SAS.
