White Matter Hyperintensity Penumbra MRI Links Hidden Damage to Cognition

by GLOOM

A 245-person BeLOVE MRI analysis found that tissue immediately surrounding white matter hyperintensities already carried measurable injury: magnetization transfer saturation was lower inside lesions than contralesional white matter, β = −0.48, p < 0.001, and the gradient extended into normal-appearing tissue around the lesion border. The cognitive signal was narrower but clinically interesting: higher perilesional …

A 2026 connected-speech study found that people with Parkinson’s disease produced more silent pauses than older controls while reading aloud: 2.185 vs. 1.595 mean pauses, while long sentences produced 2.676 pauses vs. 1.033 in short sentences.1 Within the Parkinson’s group, MoCA scores correlated with total pause count (rs = −0.502, p = 0.005).
