Abstract
OBJECTIVE: This prospective study was carried out to observe the prevalence of fatigue in patients with multiple sclerosis (MS) and its effect on quality-of-life (QoL). STUDY DESIGN AND SETTING: Prospective observational study in a University Tertiary Research Hospital in India. PATIENTS AND METHODS: A total of 31 patients (25 females) with definite MS according to McDonald's criteria presented in out-patient/admitted in the Department of Neurology (between February 2010 and December 2011) were included in the study. Disease severity was evaluated using the Kurtzke's expanded disability status scale (EDSS). Fatigue was assessed using Krupp's fatigue severity scale (FSS). QoL was assessed by the World Health Organization QoL-BREF questionnaire. RESULTS: The mean age of patients was 30.1 +/- 9.1 years. The mean age at first symptom was 25.23 +/- 6.4 years. The mean number of relapses was 4.7 +/- 3.6 in the patients. The mean duration of illness was 4.9 +/- 4.4 years. The mean EDSS score was 3.5 +/- 2.2. Mean fatigue score was 38.7 +/- 18.5 (cut-off value 36 in FSS). The prevalence of fatigue in patients with MS was 58.1% (18/31). MS patients with fatigue were significantly more impaired (P < 0.05) on all QoL domains (i.e., physical, psychosocial, social, and environment) than MS patients without fatigue. CONCLUSION: Prevalence of fatigue was found to be high in the MS patients in the study. All four domains of QoL were significantly more impaired in the group with fatigue than in those without fatigue.
