Impaired Temporal Processing in Multiple Sclerosis: Links to Basal Ganglia Damage and Fatigue

This study demonstrates that people with MS show measurable deficits in both perceptual timing (beat detection) and motor timing (finger-tapping consistency) compared to normative data, attributed to basal ganglia microstructural damage. These timing impairments correlate significantly with disease progression and fatigue severity, suggesting temporal processing measures could serve as objective biomarkers for MS disease activity.
