Correlations in Cognitive Performance and Physical Disability in Multiple Sclerosis

A systematic review and meta-analysis involving 16,340 records found moderate correlations between cognitive performance (measured by scales like SDMT, MMSE, and MoCA) and physical disability in multiple sclerosis (MS) patients, particularly for those with higher disability scores.

Why it matters

These findings indicate a significant relationship between cognitive and physical disabilities in MS, suggesting that cognitive performance may be an important factor in understanding the overall impact of the disease.

What this does not prove

The study acknowledges that the findings may not be consistent across all studies, indicating potential variability in how cognitive and physical disabilities relate in different populations of MS patients.

primary endpointIn this systematic review and meta-analysis, we aim to clarify and quantify the association between physical disability and cognitive performance in PwMS, while also examining potential modifiers and the clinical relevance of this relationship.

findingsRESULTS: There were moderate pooled correlations between EDSS and SDMT (r = -0.42), Mini-Mental State Examination (MMSE) (r = -0.46), and Montreal Cognitive Assessment (MoCA) (r = -0.43).
