This study found that the "Sleep Well, Think Well" intervention significantly improved subjective sleep quality in older adults with mild cognitive impairment (MCI). The program showed a moderate, though not statistically significant, effect on reducing daytime sleepiness.

Area of Science:

  • Gerontology
  • Sleep Medicine
  • Cognitive Neuroscience

Background:

  • Sleep-wake disturbances are linked to cognitive decline and increased dementia risk in older adults.
  • Interventions targeting sleep may be crucial for individuals at risk of dementia.
  • Mild cognitive impairment (MCI) affects sleep quality and cognitive function.

Purpose of the Study:

  • To evaluate the efficacy of a four-session multicomponent group intervention for individuals with MCI.
  • To assess the impact of the "Sleep Well, Think Well" (SWTW) program on sleep quality and other health outcomes.
  • To determine if targeting sleep disturbances can benefit cognitive health in MCI patients.

Main Methods:

  • Thirty-five older adults with MCI were randomized into the SWTW group or a passive control group.

  • The SWTW group received four face-to-face sessions, while the control group received written materials.
  • Both groups received coaching phone calls; primary outcome was subjective sleep quality (PSQI).

    • Main Results:

    • The SWTW intervention significantly improved subjective sleep quality (Cohen's d = 0.83, p < 0.02).
    • A moderate, non-significant effect was observed in reducing daytime sleepiness (Cohen's d = 0.70, p = 0.08).
    • No significant changes were noted in actigraphy sleep measures, depressive symptoms, or cognitive functioning.

    Conclusions:

    • The eight-week SWTW group intervention effectively improved subjective sleep quality in individuals with MCI.
    • The intervention demonstrated a promising, albeit non-significant, trend towards reducing daytime sleepiness.
    • Targeting sleep quality may be a viable strategy for managing MCI symptoms.
