What are frequently observed sleep patterns in individuals with advanced Alzheimer’s?

Individuals with advanced Alzheimer's disease often experience significant disruptions in their sleep patterns, leading to increased daytime sleeping and restless nights. This phenomenon can be attributed to several factors characteristic of the disease. As cognitive function declines, individuals may have difficulty regulating their circadian rhythms, which govern sleep-wake cycles. Consequently, they might exhibit prolonged periods of inactivity and drowsiness during the day, while simultaneously experiencing agitation or restlessness during nighttime hours.

The tendency for increased daytime sleeping can also relate to mental fatigue as individuals struggle to navigate their environment and cope with cognitive demands. Nighttime restlessness may manifest as difficulty settling down to sleep, frequent awakenings, or wandering behavior, all indicative of an impaired ability to achieve restorative sleep.

These altered sleep patterns stand in contrast to other options that suggest more regular or undisturbed sleep, which are not typically observed in those with advanced Alzheimer's. Understanding these patterns aids caregivers and healthcare providers in addressing the needs and behaviors associated with sleep disturbances in this population.
