Leukocyte Telomere Length and Lacunar Stroke: A Mendelian Randomization Study.

Lacunar stroke is a cerebral small vessel disease that accounts for nearly 25％ of cases of ischemic stroke. As an age-related disease, the incidence of lacunar stroke increases with age. Generally, biological age is equal to chronological age. However, under the influence of a range of chronic diseases and circumstances, the biological age can accelerate, which may contribute to the variation in risk of illness and death between individuals.
