In clinical trials, physical exercise has been shown to improve processing speed. More research is needed to demonstrate the type of exercise that is most beneficial and the extent of improvement in cognitive function that results.
SUMMARY
Cognitive function can be negatively impacted by MS. Activities of daily living, including employment and relationships, can be negatively impacted by changes in cognition. Regular screening of cognition is recommended by the National MS Society, using validated screening tools such as the SDMT. Additional testing is warranted for individuals reporting cognitive difficulties at home or work, or those who score below controls on screening tests. Cognitive rehabilitation may help some individuals improve their cognitive function. More research is needed to identify additional cognitive training techniques, better understand the role of physical exercise, and identify medications that may be of benefit to maintain cognitive function.
