The efficacy of the modified Story Memory Technique in progressive MS

BACKGROUND: Impairments in new learning and memory are common in individuals with multiple sclerosis (MS), negatively impacting everyday life, including occupational and social functioning. OBJECTIVE: This study examined the efficacy of the modified Story Memory Technique (mSMT) in a progressive multiple sclerosis (PMS) sample through a double-blind, placebo-controlled, randomized clinical trial (RCT). METHODS: met with the therapist at the same frequency, engaging in non-training-oriented tasks to control for professional contact and disease alterations. RESULTS: The treatment group showed significant improvements in learning compared with the placebo control group, evident on both objective evaluation of new learning and self-report of functioning in daily life. Increased awareness of cognitive deficits was also noted post-treatment. CONCLUSION: These data provide Class I evidence supporting the efficacy of the mSMT in PMS. A behavioral intervention, targeted to specifically strengthen new learning, can significantly improve memory performance in PMS, and this improvement in memory performance is maintained 3 months later.
