Psychosis and cognitive difficulties may be initial symptoms of relapsing‐remitting multiple sclerosis (RRMS), a case report says. “A case report revealing acute onset psychosis and cognitive impairment as primary manifestation in relapsing‐remitting multiple sclerosis” was published in the journal…

Cognitive problems are common in people with multiple sclerosis (MS) but inadequately addressed by disease-modifying therapies, while cognitive rehabilitation and exercise training programs can be effective, a review study reported.  Research studies of exercise programs need to include larger groups of patients with demonstrated cognitive difficulties, however, and more pharmacological…

Four weeks of mindfulness meditation helped to improve thinking skills and a sense of emotional balance in people with multiple sclerosis (MS), and to a greater extent than cognitive training given to a separate patient group, a pilot clinical trial reports.  These results were detailed in two studies,“…

People with secondary progressive multiple sclerosis (SPMS) who began treatment with Mayzent early and continued its use for years are less likely to experience disability progression than those starting the medication later in their disease course, five-year data from the EXPAND study suggest. Data from this same Phase 3…

People in Japan with lesions in the cerebral cortex due to multiple sclerosis (MS) were found to have greater cognitive problems, or difficulties thinking, than those without lesions in this area of mostly gray matter that surrounds the brain, a study reports.  Lesions confined to the…

Ethnicity does not seem to have an influence on the degree of cognitive impairment seen in patients at the early stages of multiple sclerosis (MS), a U.S.-based study suggests. The study, “Race, ethnicity, and cognition in persons newly diagnosed with multiple sclerosis,” was published in the…

Treatment for two months with N-acetylcysteine, or NAC — a natural molecule that enhances the levels of antioxidants — significantly improved metabolic activity in certain brain regions among people with multiple sclerosis (MS), a small clinical study reports. This increase in metabolic activity was accompanied by improvements…

Progressive cognitive decline in patients with multiple sclerosis (MS) may not be as inevitable as previously thought, a study suggests. The study, “A longitudinal study of cognitive function in multiple sclerosis: is decline inevitable?,” was published in the Journal of Neurology. Statistics indicate that some kind…

Prospective memory — the ability to remember to carry out a future task — is significantly impaired in multiple sclerosis (MS) patients, and may contribute to worse cognitive performance for everyday tasks, according to recent research. The study “Time-Based Prospective Memory Is Associated with Functional Performance in Persons…

Effective money management, critical to independent living, is particularly  difficult for people whose multiple sclerosis (MS) affects executive thinking skills and who struggle with depression and anxiety, a study reports.
