The impact of fatigue on people with multiple sclerosis in Morocco.

Background: Multiple sclerosis (MS), fatigue is among the leading clinical symptoms. It is one of the most disabling symptoms for most MS people.

Objectives: This research measures the prevalence of fatigue and its impact on the physical, cognitive, and psychosocial abilities of individuals with MS in Morocco.

Method: This cross-sectional and descriptive study included 152 participants. Data were collected via an online survey using the snowball method, incorporating sociodemographic characteristics and the Arabic version of the Modified Fatigue Impact Scale.

Results: According to the results, 89.4% of respondents experienced pathological fatigue, with an average score of 65.52 (± 18.00). There was a significant relationship between pathological fatigue, age (p = 0.0324), and clinical phenotype (p = 0.041). Fatigue negatively impacted participants' physical, cognitive, and psychological capacities, with average scores of 70.38 (± 8.15), 62.28 (± 10.23), and 73.87 (± 1.86), respectively.

Conclusion: The results of our study confirmed a high prevalence of fatigue among people with MS in Morocco. Sustained research in this field remains crucial, as it enables the formulation of strategies aimed at enhancing the quality of life for those impacted by MS.

Contribution: This study is the first in Morocco to examine fatigue prevalence in people with MS and its impact on their physical, cognitive, and psychosocial abilities. High fatigue levels hinder the integration of people with MS into professional and student life. The findings emphasize the need for effective symptom and fatigue management.
