Sleep architecture and the risk of incident dementia in the community

Open access

Abstract

OBJECTIVE: Sleep disturbance is common in dementia, although it is unclear whether differences in sleep architecture precede dementia onset. We examined the associations between sleep architecture and the prospective risk of incident dementia in the community-based Framingham Heart Study (FHS). METHODS: Our sample comprised a subset of 321 FHS Offspring participants who participated in the Sleep Heart Health Study between 1995 and 1998 and who were aged over 60 years at the time of sleep assessment (mean age 67 ± 5 years, 50% male). Stages of sleep were quantified using home-based polysomnography. Participants were followed for a maximum of 19 years for incident dementia (mean follow-up 12 ± 5 years). RESULTS: We observed 32 cases of incident dementia; 24 were consistent with Alzheimer disease dementia. After adjustments for age and sex, lower REM sleep percentage and longer REM sleep latency were both associated with a higher risk of incident dementia. Each percentage reduction in REM sleep was associated with approximately a 9% increase in the risk of incident dementia (hazard ratio 0.91; 95% confidence interval 0.86, 0.97). The magnitude of association between REM sleep percentage and dementia was similar following adjustments for multiple covariates including vascular risk factors, depressive symptoms, and medication use, following exclusions for persons with mild cognitive impairment at baseline and following exclusions for early converters to dementia. Stages of non-REM sleep were not associated with dementia risk. CONCLUSIONS: Despite contemporary interest in slow-wave sleep and dementia pathology, our findings implicate REM sleep mechanisms as predictors of clinical dementia.

TL;DR

In community-dwelling Framingham Heart Study Offspring participants older than 60, lower REM sleep percentage and longer REM sleep latency were prospectively associated with higher incident dementia risk over a mean 12 years. Non-REM sleep stages were not associated with dementia risk, implicating REM sleep mechanisms rather than slow-wave sleep.

Key findings

  • Among 321 participants (mean age 67 ± 5 years, 50% male; mean follow-up 12 ± 5 years, maximum 19 years), there were 32 incident all-cause dementia cases, including 24 Alzheimer disease (AD) dementia cases.
  • Each 1% lower REM sleep percentage was associated with approximately a 9% higher risk of incident all-cause dementia: age/sex-adjusted HR 0.91 (95% CI 0.86–0.97, p = 0.004); fully adjusted HR 0.91 (95% CI 0.85–0.98, p = 0.01). AD dementia results were similar (age/sex-adjusted HR 0.92, 95% CI 0.86–0.99, p = 0.02).
  • The lowest vs highest tertile of REM sleep latency was associated with lower all-cause dementia risk in model 1 (HR 0.37, 95% CI 0.14–0.97) and model 2 (HR 0.26, 95% CI 0.08–0.85). Higher wake after sleep onset was associated with increased risk only in model 2 (HR 2.08, 95% CI 1.02–4.23). Stages 1, 2, and slow-wave sleep were not significantly associated with dementia risk.
  • Sensitivity analyses excluding MCI at baseline or early converters did not materially change the REM sleep association. Excluding persons with high REM arousals due to hypopnea attenuated the association (all-cause dementia HR 0.94, 95% CI 0.88–1.01, p = 0.09). An APOE ε4 by REM sleep percentage interaction was found for AD dementia (p = 0.05), with lower REM sleep associated in ε4 noncarriers (HR 0.88, 95% CI 0.80–0.96) but not carriers (HR 0.99, 95% CI 0.90–1.08), though the authors caution interpretation.

Methods

  • Prospective cohort study using a subset of 321 Framingham Heart Study Offspring participants aged over 60 at the time of home-based polysomnography in the Sleep Heart Health Study (1995–1998); exclusions from 699 Offspring participants included age <60, prevalent dementia, no dementia follow-up, and missing PSG data.
  • Sleep stages were scored in 30-second epochs using Rechtschaffen and Kales criteria; primary exposures were percentage of time in stage 1, stage 2, slow-wave sleep (stages 3 and 4 combined), and REM sleep, with secondary measures of sleep continuity, fragmentation, and sleep-disordered breathing.
  • Incident dementia was ascertained through Framingham Heart Study surveillance, MMSE screening, neuropsychological/neurologic evaluations, and dementia review committee adjudication using DSM-IV; AD dementia used NINCDS-ADRDA criteria. Cox proportional hazards models were used: model 1 adjusted for age and sex; model 2 additionally adjusted for BMI, education, APOE ε4, systolic blood pressure, smoking, diabetes, heart disease, depressive symptoms, and medication use.

Limitations

  • The paper states small sample size and small number of incident events, limiting power to detect weaker associations with other sleep exposures, including the AHI ≥15 threshold; the sample was of Caucasian descent, so generalizability to other ethnic groups is unclear.
  • The paper states no information on shift work, preventing ascertainment of circadian rhythm sleep disorders.
  • Evident from the text: the APOE ε4 interaction for AD dementia was based on small event counts and overlapping confidence intervals; the single baseline PSG cannot capture changes in sleep architecture over follow-up, and observational design leaves potential residual confounding.

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.

A language model drew the claims from the paper on 2026-11-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
