Alzheimer's disease and slow wave sleep share a bidirectional relationship where the disease alters sleep architecture by reducing slow wave sleep [1], [2], while the deterioration of slow wave sleep contributes to the accumulation of amyloid-β plaques associated with the disease [3], [4].

claimAlzheimer’s disease causes an increased number of arousals and alters an individual’s sleep architecture, resulting in increased time spent in stage 1 sleep and a reduced percentage of time in stage 2 and slow-wave sleep (SWS).
claimIndividuals with Alzheimer’s disease spend an increased percentage of time in stage 1 sleep and a reduced percentage in stage 2 and slow-wave sleep (SWS) due to an increased duration and number of awakenings.

claimThere is a bidirectional relationship between the deterioration of slow wave sleep and Alzheimer’s dementia: the disruption of slow wave sleep increases amyloid-β plaques, and experimental increases of amyloid-β result in decreased and fragmented slow wave sleep.

claimSlow-wave sleep (deep sleep) decreases with age, and lower amounts of deep sleep are associated with an increase in beta amyloid, a protein that accumulates in people with Alzheimer’s disease.
