Beyond the sleep-amyloid interactions in Alzheimer’s disease pathogenesis
Sleep and amyloid protein interactions in Alzheimer's disease development

Abstract
Cognitive impairment in older adults is associated with sleep and circadian rhythm disturbances.
- Disrupted sleep and circadian rhythms are linked to amyloid-β (Aβ), a key factor in Alzheimer's disease (AD).
- Aβ may initiate the pathogenesis of AD, while tau appears to drive neurodegeneration.
- Recent studies suggest that sleep-wake cycles may have a greater impact on brain tau levels than on Aβ levels.
- Alterations in sleep patterns could accelerate AD progression and cognitive decline.
- Understanding sleep disturbances may clarify mechanisms underlying AD and dementia.
