  • Descrição: Background: There is much evidence regarding the causal connection between fatigue and depression in multiple sclerosis (MS) patients. Poor sleep quality could be considered as a cause or effect of physical and cognitive impairment, and could worsen fatigue levels. However, there are still doubts about the profile of sleep quality of MS patients and its relationship with fatigue and depression. Objective: Our aim was to verify the relationship between fatigue, subjective sleep quality and depression in MS patients. Methods: Eighteen (12 women) relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS) patients clinically defined as mild to moderate disability (EDSS scores 1 to 6.5) were interviewed and answered the Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), Fatigue Severity Scale (FSS) and Epworth Sleepiness Scale. Descriptive statistics (frequency, median, mean and standard deviation) and Spearman correlations were used to analysis (p<0.05). Results: Mean PSQI, FSS and BDI global scores were 6.89 plus or minus 3.51, 36.94 plus or minus 16.54 and 12.5 plus or minus 7.71, respectively. Fatigue and depression have shown good positive correlation (r=0.814 p<0.001). There was no correlation between sleep quality and fatigue; however, poor subjective sleep quality (PSQI>5) was found in 12 patients (66.6%) and mild or moderate depression (BDI>9) was found in 10 patients (55.6%). Conclusions: The relationship between fatigue and depression corroborates results found in other studies. Despite the absence of a significant correlation between sleep quality and fatigue/depression, it is important to highlight the high incidence of poor sleep quality in this sample. Symptoms linked to sleep deprivation can negatively influence the quality of life in MS patients.
