Core Tip
Core Tip: Yue et al's study links reduced gray matter volume (GMV) in specific brain regions (temporal, frontal, occipital, parietal) to both cognitive decline and impaired motor function (gait disturbances) in patients with amnestic mild cognitive impairment (aMCI). Utilizing voxel-based morphometry, the study found correlations between regional atrophy and performance on tests like mini-metal state examination, Cambridge cognitive examination-Chinese version, timed up and go test, and walking speed. This reinforces GMV's potential as an aMCI biomarker and supports the idea of shared brain networks for cognition and motor control. However, the cross-sectional design prevents establishing causality. Future longitudinal research is essential to clarify the temporal relationship between brain atrophy and functional decline in aMCI.
