Abstract
Abstract
Multiple sclerosis (MS) is a neurological disease of the central nervous system which can lead to a range of severe physical disabilities. A large proportion of those affected will experience cognitive impairment, which is associated with a worse prognosis. Effective assessment of cognition in MS has been problematic due to a lack of suitable scales. The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) was developed in 2010 as part of an international endeavour to facilitate cognitive assessment.
Aim
The aim of this systematic review and meta-analysis was to synthesise the available literature published as part of the BICAMS international validation protocol.
Methods
A literature search conducted using PubMed, PsycINFO and Google Scholar identified 16 studies for inclusion in the systematic review, 14 of which could be included in a meta-analysis.
Results
BICAMS has been widely validated across 11 languages and 14 individual cultures and locations. The meta-analysis demonstrated that BICAMS identified significantly reduced cognitive functioning in adults with MS compared to healthy controls. This was true for all three cognitive domains assessed by BICAMS: information processing speed (g = 0.943, 95% CI 0.839, 1.046, g < 0.001), immediate verbal recall memory (g = 0.688, 95% CI 0.554, 0.822, p < 0.001) and immediate visual recall memory (g = 0.635, 95% CI 0.534, 0.736, p < 0.001).
Conclusion
BICAMS has been widely applied across cultures and languages to assess cognition in MS. BICAMS offers a feasible, cost-effective means of assessing cognition in MS worldwide. Further validation studies are underway to support this project.
