Mid-life stroke risk factors are linked to smaller brain volume and reduced cognitive function in older adults. Managing these risks may help preserve brain health and cognitive abilities later in life.

Area of Science:

  • Neurology
  • Neuroimaging
  • Cognitive Science

Background:

  • Mid-life stroke risk factors are associated with late-life cognitive impairment.
  • Subclinical brain injury, like global atrophy on MRI, may mediate this link.
  • Understanding this relationship is crucial for preventing cognitive decline.

Purpose of the Study:

  • To investigate the association between stroke risk factors and brain volume.
  • To examine the relationship between brain volume and cognitive function.
  • To determine if stroke risk factors predict cognitive function via brain atrophy.

Main Methods:

  • Analysis of the Framingham Offspring Study cohort (1,841 participants).
  • Quantitative MRI to assess total cerebral brain volume ratio (TCBVr).

  • Linear regression models relating Framingham Stroke Risk Profile (FSRP) scores to TCBVr and cognitive test performance.

    • Main Results:

    • Inverse association found between FSRP scores and TCBVr.
    • TCBVr positively correlated with attention, executive function, and visuospatial skills.
    • No significant association between TCBVr and verbal memory or naming.

    Conclusions:

    • The FSRP can identify individuals with reduced brain volume and cognitive function.
    • Managing stroke risk factors is important for maintaining brain health and cognitive function.
    • Findings highlight the role of subclinical brain changes in cognitive aging.
