Fatigue is one of the most frequent and disabling symptoms in multiple sclerosis (MS). Central, psychological, and peripheral factors may contribute to the occurrence of fatigue. Objectives: The current study aimed to evaluate potential fatigue determinants in patients with relapsing-remitting MS with a low functional impairment. Methods: We compared inflammatory markers, respiratory pressures, disability, and quality of life in 39 relapsing-remitting MS patients with and without fatigue. Results: Patients with relapsing-remitting MS with fatigue had higher Expanded Disability Status Scale scores (p = 0.002). We observed a significant association between the results of the Guy Neurological Disability Scale, the Functional Assessment of MS Quality of Life Rating Scale and the presence of fatigue (p < 0.05). Conclusions: The degree of functional impairment is a determinant for the presence of fatigue in MS patients, but respiratory function and inflammatory markers are not.
