Alzheimer's disease and sleep disturbance are linked as sleep disturbances are frequently observed in patients with the disease [1], [2], [3], and are associated with increased cognitive impairment and behavioral symptoms [4], [5], [6]. Furthermore, research suggests that sleep disturbances may contribute to the pathogenesis of Alzheimer's disease through neuroinflammatory pathways [7], [8].
