| Objectives: Multiple sclerosis (MS) is the chronic inflammatory and demyelinating disorder of central nervous
system which is accompanied with disability and negative life style changes such as fatigue and depression.
The aim of this study is to investigate the effect of coenzyme Q10 (CoQ10) supplementation on fatigue and
depression in patients with MS.
Methods:We performed a randomized, double-blinded, placebo-controlled trial to determine the effect of CoQ10
supplement (500 mg/day) vs. placebo for 12 weeks. Fatigue symptoms were quantified by means of fatigue
severity scale (FSS) and the Beck depression inventory (BDI) was used to assess depressive symptoms.
Results: A significant decrease of FSS was observed in CoQ10 group during the intervention (P= 0.001) and
significant increase of FSS change was observed within placebo group (P = 0.001). Repeated measure
analysis of variance showed a significant time-by-treatment interaction for FSS (baseline 41.5 ± 15.6 vs.
endpoint 45 ± 13.6; F1,45 = 55.23, P < 0.001, η2 = 0.56) and BDI (baseline 17.8 ± 12.2 vs. endpoint 20.4 ±
11.4; F1,45 = 40.3, P < 0.001, η2 = 0.48), indicating significant decrease of FSS and BDI in CoQ10 group
compared to placebo group.
Conclusion: Our study suggests that CoQ10 supplementation (500 mg/day) can improve fatigue and
depression in patients with multiple sclerosi |
