Caregivers often report sleep disturbances in persons with dementia. Older adults with dementia have more nighttime awakenings, less deep sleep, more daytime sleepiness and napping, and experience changing in the timing of sleep. Sleep disorders such as sleep disordered breathing, restless legs syndrome, periodic limb movement disorder, and REM behaviour disorder are more common among individuals with some types of dementia. Sleep problems are associated with difficulties in caregiving and quality of life. As a result, sleep problems should be evaluated and treated. Treatment should always consider nighttime environmental and daytime lifestyle factors.
Key words: sleep, dementia, Alzheimer’s disease, circadian rhythms, sleep disorders.
