Brain Age Acceleration in People with MS
In a study involving 163 people with MS, periods of radiologically active lesions were linked to a greater acceleration in brain age by +0.19 years per year compared to stable periods. The brain age acceleration was normalized during subsequent stable intervals.

Why it matters
These findings suggest that new lesion activity in MS correlates with increased brain aging, promoting further investigation on the impacts of lesion dynamics in MS progression.
What this does not prove
This study is unpublished, derived from observational data without a controlled framework, limiting causal inferences.
Next milestone
No next milestone was established from the available source.

findingsRadiologically active intervals (138 of 333) were associated with +0.19 yr/yr greater brain age acceleration than stable intervals (95% CI: 0.03-0.37; p=0.022), scaling with lesion count (β=+0.18; p=0.001) and volume.
