Abstract: With the publication of the Multiple Sclerosis Council Guideline on the management of multiple sclerosis (MS) fatigue, there has been increased appreciation for the role fatigue can play in MS. Secondary fatigue is fatigue caused by other etiologies than those directly related to MS. Once these causes are ruled out, fatigue is related to MS. Secondary MS-related fatigue comes as result of the symptoms of MS that drain energy. Once secondary MS causes are ruled out, then the patient is deemed as having primary MS fatigue. Fatigue management is both nonpharmacologic and pharmacologic. Occupational therapists are the major allied health providers that address the role fatigue plays in MS patients. Over the past two decades, numerous clinical trials have been conducted on drugs for treating MS-related fatigue. Of these agents, amantadine has been studied for the longest period, and has shown efficacy in about one third of patients with MS-related fatigue on several commonly used scales. Two randomized -trials of the central nervous system stimulant pemoline have yielded unimpressive results; efficacy was seen at higher doses but coupled with an unacceptable risk of adverse events. The wake-promoting agent modafinil is the only agent to show efficacy compared with placebo on the Fatigue Severity Scale, a measure that is highly resistant to "impulse answering" and is thus viewed as one of the most difficult scales on which to show -benefit. This article reviews fatigue in MS and proposes a rational strategy for evaluation and management of this most common MS symptom.

Abstract: OBJECTIVE: To assess the efficacy and safety of modafinil for the treatment of fatigue in multiple sclerosis (MS). METHODS: Patients aged 18-65 years with a diagnosis of MS, a stable disability level < or =6 on the Kurtzke extended disability status scale (EDSS), and a mean score >4 on the fatigue severity scale (FSS) were eligible for the 9 week, single blind, phase 2, two centre study. Exclusion criteria included a diagnosis of narcolepsy, sleep apnoea, or clinically significant major systemic disease and recent use of medications affecting fatigue. All patients, who remained blinded for the treatment regimen, received placebo during weeks 1-2, 200 mg/day modafinil during weeks 3-4, 400 mg/day modafinil during weeks 5-6, and placebo during weeks 7-9. Safety was evaluated by unblinded investigators. Efficacy was evaluated by self rating scales, using the FSS, the modified fatigue impact scale (MFIS), a visual analogue scale for fatigue (VAS-F), and the Epworth sleepiness scale (ESS). Adverse events were recorded. RESULTS: Seventy two patients (MS type: 74% relapsing-remitting; 7% primary progressive; 19% secondary progressive) received treatment. After treatment with 200 mg/day modafinil for 2 weeks, a significant improvement in fatigue versus placebo run in was demonstrated. Mean scores after treatment with 200 mg/day modafinil were: FSS, 4.7 versus 5.5 for placebo (p<0.001); MFIS, 37.7 versus 44.7 (p<0.001); and VAS-F, 5.4 versus 4.5 (p=0.003). Fatigue scores for 400 mg/day modafinil were not significantly improved versus placebo run in. Mean ESS scores were significantly improved (p<0.001) with 200 mg/day modafinil (7.2) and 400 mg/day (7.0) versus the score at baseline (9.5). Serious adverse events were not found at either dose. The most common adverse events were headache, nausea, and aesthenia. Sixty five patients (90%) completed the study. CONCLUSIONS: These data suggest that 200 mg/day modafinil significantly improves fatigue and is well tolerated in patients with MS.
