Abstract

IMPORTANCE: Sleep and circadian problems are very common in Alzheimer disease (AD). Recent animal studies suggest a bidirectional relationship between sleep and β-amyloid (Aβ), a key molecule involved in AD pathogenesis. OBJECTIVE: To test whether Aβ deposition in preclinical AD, prior to the appearance of cognitive impairment, is associated with changes in quality or quantity of sleep. DESIGN: Cross-sectional study conducted from October 2010 to June 2012. SETTING: General community volunteers at the Washington University Knight Alzheimer's Disease Research Center. PARTICIPANTS: Cognitively normal individuals (n = 145) 45 years and older were recruited from longitudinal studies of memory and aging at the Washington University Knight Alzheimer's Disease Research Center. Valid actigraphy data were recorded in 142. The majority (124 of 142) were recruited from the Adult Children Study, in which all were aged 45 to 75 years at baseline and 50% have a parental history of late-onset AD. The rest were recruited from a community volunteer cohort in which all were older than 60 years and healthy at baseline. MAIN OUTCOME MEASURES: Sleep was objectively measured using actigraphy for 2 weeks. Sleep efficiency, which is the percentage of time in bed spent asleep, was the primary measure of sleep quality. Total sleep time was the primary measure of sleep quantity. Cerebrospinal fluid Aβ42 levels were used to determine whether amyloid deposition was present or absent. Concurrent sleep diaries provided nap information. RESULTS: Amyloid deposition, as assessed by Aβ42 levels, was present in 32 participants (22.5%). This group had worse sleep quality, as measured by sleep efficiency (80.4% vs 83.7%), compared with those without amyloid deposition, after correction for age, sex, and APOEε4 allele carrier status (P = .04). In contrast, quantity of sleep was not significantly different between groups, as measured by total sleep time. Frequent napping, 3 or more days per week, was associated with amyloid deposition (31.2% vs 14.7%; P = .03). CONCLUSIONS AND RELEVANCE: Amyloid deposition in the preclinical stage of AD appears to be associated with worse sleep quality but not with changes in sleep quantity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Increases in beta-amyloid and tau may interrupt the sleep-wake cycle, leading to increased sleep fragmentation and wakefulness and decreased slow-wave sleep.

    From 2024 Alzheimer's disease facts and figures (2024) · cites this paper as [217]

    The Discussion (page unavailable) says amyloid deposition may disrupt sleep–wake cycles and describes fragmented sleep and increased wakefulness after plaque formation in mice. The Results (page unavailable) also associate amyloid deposition with more wake time after sleep onset in humans. The paper does not establish that tau causes these changes or that slow-wave sleep decreases. (LLM, conf=0.88)

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.
