Cognitive changes are common among individuals with multiple sclerosis (MS), affecting 40-60% of the MS population. Much like physical MS symptoms, cognitive changes vary widely from person to person. Whereas many individuals with MS experience slowed processing speed as their predominate cognitive difficulty, others may experiences problems across a number of cognitive areas including learning, memory, problem-solving, and word-finding. Given the wide range of cognitive difficulties, treatments for cognitive impairment in MS are not a one-size-fits-all approach.
