Sleep and mild cognitive impairment

The prevalence of cognitive impairment and dementia is increasing at a rapid pace. Alzheimer's disease (AD) is the most prevalent cause of dementia. The Alzheimer Society of Canada states that 747,000 Canadians had AD in 2011 and that the current estimated costs of dementia for Canada is around $33 billion annually. The degenerative process leading to AD is believed to start decades before the onset of dementia. This long and progressive period is called mild cognitive impairment (MCI) but not all individuals with MCI will develop AD. The identification of earlier markers to detect which MCI individuals will progress to AD is urgently needed for the development and assessment of preventive and therapeutic strategies. Up to now, promising markers measuring brain activity have been identified in awake patients. We propose that rapid-eye-movement (REM) sleep is a more sensitive state than wakefulness to detect early neurodegeneration in MCI patients. Indeed, during REM sleep, the activity of the acetylcholine system, which is affected early in MCI, is not masked by other systems that are active during wakefulness. The goal of this project is to predict, in individuals with MCI, those who will develop AD three years later by studying REM sleep characteristics. We will also validate that REM sleep is linked to the integrity of the cholinergic system using brain imaging. If our hypotheses are confirmed, REM sleep characteristics have the potential to become a reliable non-invasive and low-cost tool to help identify MCI individuals at high risk of progressing to AD and test the efficacy of preventive treatments.
