What percentage of individuals with Multiple Sclerosis experience cognitive impairment?

Individuals with Multiple Sclerosis (MS) often experience cognitive impairment, which can significantly affect their daily functioning and quality of life. Research indicates that approximately 60% of those diagnosed with MS will encounter some form of cognitive dysfunction during their illness. This cognitive impairment can manifest in various ways, including difficulties with attention, memory, and executive functions, among others.

The estimates suggesting that a lower percentage, such as 30% or 40%, underestimate the prevalence of cognitive issues related to MS, given that many patients may not initially recognize or report their cognitive challenges. On the other hand, suggesting that 80% of individuals experience cognitive impairment is on the higher end of the spectrum, as not all patients will have pronounced cognitive decline. Therefore, 60% serves as a widely accepted figure reflecting the reality of cognitive impairment in the MS population, underscoring the importance of monitoring and addressing cognitive health in these individuals.
