Abstract

Sleep disturbances are associated with future risk of Alzheimer disease. Disrupted sleep increases soluble amyloid β, suggesting a mechanism for sleep disturbances to increase Alzheimer disease risk. We tested this response in humans using indwelling lumbar catheters to serially sample cerebrospinal fluid while participants were sleep‐deprived, treated with sodium oxybate, or allowed to sleep normally. All participants were infused with 13 C 6 ‐leucine to measure amyloid β kinetics. We found that sleep deprivation increased overnight amyloid β38, amyloid β40, and amyloid β42 levels by 25 to 30% via increased overnight amyloid β production relative to sleeping controls. These findings suggest that disrupted sleep increases Alzheimer disease risk via increased amyloid β production. Ann Neurol 2018;83:197–204

  • A study involving cognitively healthy adults showed that amyloid-beta in cerebrospinal fluid or the hippocampus increases after sleep deprivation or slow-wave sleep disruption.

    “A study involving cognitively healthy adults showed that Aβ in CSF or the hippocampus increases after sleep deprivation or slow-wave sleep disruption, which indicates the complexity of Aβ kinetics [59, 60, 61].”

    From Clinical trials of new drugs for Alzheimer disease (2020) · cites this paper as [60]

  • In humans, SD increases CSF levels of Aβ38, Aβ40, and Aβ42 through enhancement of Aβ production.

    “In humans, SD increases CSF levels of Aβ38, Aβ40, and Aβ42 through the enhancement of Aβ production [568, 569].”
  • In humans, sleep deprivation increases CSF Aβ levels without changing the rate of Aβ clearance.

    “In a recent study of amyloid kinetics in human CSF using stable isotope labeling, there was an increase in Aβ levels following sleep deprivation but no change in rate of Aβ clearance.”

    From Alzheimer Disease: An Update on Pathobiology and Treatment Strategies (2019) · cites this paper as Lucey et al., 2018

  • The increase in Aβ after sleep deprivation is due to increased production.

    “This suggests the mechanism for increased Aβ is increased production (Lucey et al., 2018).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
