Longitudinal Cognitive and Motor Trajectories in Adults with MS

In a study with 68 adults with MS followed for six years, 52.9% had cognitive impairment at the start. Over time, 50% experienced motor worsening, and 77.9% had cognitive decline. Notably, 44.1% met criteria for cognitive progression independent of relapses, and the Memory Cognitive Impairment Index increased significantly, especially in relapsing MS patients (p = 0.003).

Why it matters

These findings highlight the high prevalence of cognitive and motor decline in MS, suggesting the need for ongoing monitoring of these aspects in patients. Understanding these trajectories may inform future care.

What this does not prove

The study identifies trends in cognitive and motor decline but does not determine causative factors and is retrospective, which could introduce biases.

Next milestone

No next milestone was established from the available source.
