Who Benefits Most from Brain Training and Exercise in Progressive MS


Listen Later

People with progressive multiple sclerosis often experience slowed cognitive processing speed. Researchers from Kessler Foundation analyzed data from the international CogEx trial, involving over 300 participants using brain training and exercise over 12 weeks. They found that improvement in cognitive speed varied, with better memory and higher pre-symptom IQ predicting greater gains. Factors like age, gender, or disability status did not affect outcomes. These findings highlight the need for personalized rehabilitation tailored to individuals’ cognitive profiles, moving beyond one-size-fits-all treatments.
