Abstract
Poststroke fatigue is a common and disabling condition. However, few studies on or therapeutic trials addressing poststroke fatigue have appeared in the literature. We aimed to review the prevalence, natural course, potential predisposing factors (physiological, psychocognitive, and organic), and pharmacological and nonpharmacological treatments of poststroke fatigue. Using PubMed CINAHL and PsycINFO, we reviewed all the available literature on poststroke fatigue and related issues. The prevalence of poststroke fatigue ranges from 23% to 75%, depending on the definition of fatigue and the characteristics of the patients included. Post-stroke fatigue seems to be of complex etiology. Predisposing factors were physiological ones including functional disability, prestroke fatigue, medical comorbidities, medication, sleep disturbances, and nutritional problems; psychocognitive ones including depression and cognitive dysfunction; and organic ones including damage to particular brain areas with consequent neurochemical alterations, perfusion deficit, and neuroinflammation. Poststroke fatigue is a persistent and debilitating symptom in some patients, and can have adverse affects on patient's neurological recovery, quality of life, and mortality. Few therapeutic trials have been reported, and the therapy was rarely successful, possibly because of the complex nature of poststroke fatigue. Poststroke fatigue is a common and frequently disabling problem of complex etiology. Further studies are urgently needed to improve our understanding of the pathophysiology of post-stroke fatigue and to develop better treatments for this condition.
