Six-month followup of MEMREHAB trial shows persistence of cerebral activation associated with learning
Kessler Foundation researchers published long-term followup results of their MEMREHAB trial, which show that in individuals with MS, patterns of brain activity associated with learning were maintained at 6 months post training. The article, A pilot study examining functional brain activity 6 months after memory retraining in MS: the MEMREHAB trial, was published recently online ahead of print by Brain Imaging and Behavior. The article appeared in the Neuroimaging and Rehabilitation Special Issue. The authors are Ekaterina Dobryakova, PhD, Glenn Wylie, DPhil, John DeLuca, PhD, and Nancy Chiaravalloti, PhD, of Kessler Foundation.
This pilot study was based on the Foundation's MEMREHAB Trial, which provided the first Class I evidence for the efficacy of cognitive rehabilitation in MS. (Chiaravalloti N, et al: An RCT to treat learning impairment in MS. Neurology 2013(81) doi: 10.1212/01.wnl.0000437295.97946.a8S , was released as an epub ahead of print on November 8. The 10-session memory retraining protocol used in the MEMREHAB study was the modified Story Memory Technique (mSMT).
For the pilot study, participants underwent evaluation of memory performance and brain activity at baseline, immediately following memory retraining, and at 6-month followup. Results showed that the patterns of increased cerebral activation that correlated with learning were maintained at 6-month followup. "These results support the long-term effectiveness of cognitive rehabilitation in individuals with cognitive impairment caused by MS," said Nancy Chiaravalloti, PhD, director of Neuroscience & Neuropsychology and Traumatic Brain Injury (TBI) Research at Kessler Foundation. "For optimal care, it is crucial for clinicians who care for this population to become familiar with the mSMT protocol."
