Implication

Prospective cohort study reveals a 17.9% progression rate of white matter lesions driven by blood pressure and genetics in older adults, highlighting vascular and hereditary risks.

Key Points

To evaluate the rate of progression, clinical and genetic predictors, and cognitive consequences of MRI white matter lesions in older adults without neuropsychiatric disease.
Tracked 273 participants (mean age 60 years) from the Austrian Stroke Prevention Study over a 3-year follow-up period.
Assessed lesion progression using MRI alongside baseline clinical characteristics, neuropsychological test batteries, and candidate gene polymorphism analyses.
White matter lesion progression occurred in 17.9% of participants over the 3-year observational window.
Baseline diastolic blood pressure and preexisting early confluent or confluent white matter hyperintensities were the only significant clinical predictors of progression.
Genetic association analyses revealed links between progression and both the paraoxonase Leu->Met 54 polymorphism and the angiotensinogen gene M235T polymorphism, with no detectable short-term impact on cognitive test performance.
