5 Key Takeaways

• 1

  Shorter telomeres may indicate increased risk for stroke, dementia, and late-life depression according to a study of over 356,000 individuals.

• 2

  Individuals with the shortest telomeres showed an 8% higher risk of stroke, 19% higher risk of dementia, and 14% higher risk of late-life depression.

• 3

  The study tracked participants for a median of 12 years and employed Mendelian randomization to explore causality.

• 4

  Healthier lifestyle choices may mitigate risks associated with shorter telomeres, as indicated by higher Brain Care Scores.

• 5

  The findings are preliminary and focus solely on participants of European ancestry, with limitations in measuring telomere length.
