Sleep disruption appears to be a core component of Alzheimer's disease (AD) and
its pathophysiology. Signature abnormalities of sleep emerge before clinical
onset of AD. Moreover, insufficient sleep facilitates accumulation of amyloid-?
(A?), potentially triggering earlier cognitive decline and conversion to AD.
Building on such findings, this review has four goals: evaluating (i)
associations and plausible mechanisms linking non-rapid-eye-movement (NREM) sleep
disruption, A?, and AD; (ii) a role for NREM sleep disruption as a novel factor
linking cortical A? to impaired hippocampus-dependent memory consolidation; (iii)
the potential diagnostic utility of NREM sleep disruption as a new biomarker of
AD; and (iv) the possibility of sleep as a new treatment target in aging,
affording preventative and therapeutic benefits.
