Background: Memory disturbance is common in people with multiple sclerosis (pwMS). Currently, a range of memory rehabilitation approaches alone or as a component of cognitive rehabilitation is utilized clinically.
Objective: To evaluate the effectiveness of memory rehabilitation in improving health outcomes (memory, cognitive function, functional ability, quality of life) in pwMS.
Methods: A summary of the Cochrane Review "Memory rehabilitation for people with multiple sclerosis" by Taylor et al from a rehabilitation perspective.
Results: The review included 44 studies (with 2714 participants). The memory rehabilitation approaches varied amongst the included primary studies for memory retraining techniques (computerized programs, training using internal and external memory aids, etc.). Overall, the risk of bias amongst the included trials was low. The findings suggest high-certainty evidence for a beneficial effect of memory rehabilitation in improving subjective memory at intermediate- (1-6 months) and longer-term (> 6 months); and moderate-certainty evidence at immediate post-intervention. The evidence of the effect of memory rehabilitation on other outcomes showed mixed results.
Conclusion: The evidence suggests some beneficial effects of memory rehabilitation in improving subjective memory and quality of life in pwMS. However, further evidence is required for the evaluation of memory strategies for other outcomes.
