Multiple sclerosis researchers find role for working memory in cognitive reserve

Cognitive symptoms, including deficits in long-term memory, are known to affect approximately half of individuals with MS. This study was conducted in 70 patients with MS, who were evaluated for intellectual enrichment, verbal long-term memory, and working memory capacity. "We found that working memory capacity explained the relationship between intellectual enrichment and long-term memory in this population," said Dr Sandry. "This suggests that interventions targeted at working memory in people with MS may help build cognitive reserve to protect against decline in long-term memory."
