Predictors of Fatigue Trajectories in Multiple Sclerosis

This study investigates how fatigue levels change over time for individuals with relapsing-remitting multiple sclerosis. Researchers identified three distinct patterns for both physical and cognitive exhaustion, ranging from patients who improved to those whose symptoms significantly worsened. The analysis revealed that a smaller cervical spinal cord area serves as the most reliable biological indicator for predicting an increase in fatigue. Additionally, the length of time spent on disease-modifying treatments was found to be a critical clinical factor in determining these patient outcomes. These findings suggest that spinal cord imaging should play a larger role in assessing the future progression of the disease. Ultimately, the research highlights the heterogeneous nature of MS symptoms and the importance of personalized prognostic tools.
