Post-stroke fatigue and its dimensions within first 3 months after stroke

Abstract

Post-stroke fatigue (PSF) is a common stroke complication with long-term negative consequences. Assess the qualitative and quantitative PSF characteristics during 3 month post-stroke period. There were examined 141 patients with acute ischemic or hemorrhagic strokes at hospital stay, in 1, 2 and 3 months after stroke. PSF was measured by fatigue assessment scale (FAS), multidimensional fatigue inventory-20 (MFI-20) and fatigue severity scale (FSS). 116 (82.3%) patients had ischemic strokes, 25 (17.7%) had hemorrhagic strokes. According to FAS and MFI-20" global fatigue" sub-scale, PSF was present, respectively, in 22.0% and 25.5% cases at hospital stay, in 38.3% and 35.5% cases in 3 month after stroke. The growing prevalence of PSF was based on significantly increasing the rates of PSD physical domain (from 28.4% to 41.1%) and the rates of PSF mental domain (from 19.1% to 31.9%). On the other hand, the rates of PSF activity-related component had been significantly reduced from 36.2% to 17.0% within observation period. Moreover, according to MFI-20, it had been revealed significant increasing of PSF intensities in global, physical and mental domains during first 3 post-stroke months. According to FSS value ranks, proportions of patients with" no PSF" had been decreased in 1.5 times due to simultaneously rising rates of" moderate" as well as" severe" PSF impacts on daily life. The PSF spreading is significantly increased during the first 3 post-stroke months due to increasing of rates and intensities of physical and mental PSF domains.
