Background and Purpose: Poststroke fatigue (PoSF) is a common, but poorly studied problem. The purpose of the present study was to elucidate the characteristics of and the factors associated with PoSF. Methods: We studied 220 consecutive outpatients at an average of 15 months after the onset of stroke. The presence of poststroke depression (PSD) and poststroke emotional incontinence were identified with the use of a standardized questionnaire. The presence of PoSF was assessed using the visual analogue scale and Fatigue Severity Scale. The presence of prestroke fatigue (PrSF) was also assessed. The impact of PoSF on patients’ daily activities was also assessed using the Fatigue Impact Scale. Results: One hundred and twenty-five patients (57%) had PoSF, 83 (38%) had PrSF and 53 (24%) had PSD. Thirty-six percent of the patients without PrSF and 50% of the patients without PSD had PoSF. The impact of PoSF on patients’ daily activities was more severe in the physical domain as compared with the psychological or cognitive domains (p < 0.01). Multivariate analyses showed that the presence of PrSF (p < 0.01, OR 33.5), high modified Rankin scale (MRS; p < 0.05, OR 3.3), PSD (p < 0.05, OR 2.7) were independently associated with PoSF. Cessation of cigarette smoking (p < 0.05) and the presence of PrSF (p < 0.01) were independently related to PoSF in patients without PSD while decrease in sexual activities (p < 0.05) and the presence of dysarthria (p < 0.05) were related to PoSF in patients without PrSF. Conclusions: Fatigue is a fairly common sequela of stroke patients, exerting an impact on their daily activities, especially physical ones. PrSF is the most important factor related to PoSF, followed by high MRS and PSD. Nevertheless, the causes of PoSF appear multifactorial. Strategies to improve the PoSF should be individualized according to the causative factors.

Development of PSD and PSEI is strongly influenced by lesion location, probably associated with the chemical neuroanatomy related to the frontal/temporal lobe-basal ganglia-ventral brainstem circuitry. Although the lesion distribution is similar, PSEI is more closely related to lenticulocapsular strokes than is PSD.

At least half of all stroke survivors experience fatigue; thus, it is a common cause of concern for patients, caregivers, and clinicians after stroke. This scientific statement provides an international perspective on the emerging evidence surrounding the incidence, prevalence, quality of life, and complex pathogenesis of poststroke fatigue. Evidence for pharmacological and nonpharmacological interventions for management are reviewed, as well as the effects of poststroke fatigue on both stroke survivors and caregivers.

Psycho-social factors outweighed the physical factors in determining QOL in Korean epilepsy patients. Recognition of these factors will lead health professionals to develop different strategies to improve the QOL of these patients.

Background and Purpose-The efficacy and safety of the selective serotonin reuptake inhibitor fluoxetine have rarely been studied in the treatment of poststroke emotional disturbances. Methods-Stroke patients (152) who had poststroke depression (PSD), emotional incontinence (PSEI), or anger proneness (PSAP) were studied. PSD was evaluated by Beck Depression Inventory and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, PSEI by Kim's criteria, and PSAP was assessed by Spielberger Trait Anger Scale. Subjects were randomly given either fluoxetine 20 mg/day (nϭ76) or placebo (nϭ76) for 3 months. Follow-up evaluations were done 1, 3, and 6 months after the beginning of the treatment. The primary outcome measurement was the scores of emotional disturbances at each follow-up assessment. The secondary outcome measurements were the percentage changes of the scores and the subjective responses of the patients. Results-Although patients in the fluoxetine group more often dropped out because of adverse effects, fluoxetine administration was generally safe. Fluoxetine significantly improved PSEI and PSAP, whereas no definitive improvement of PSD was found. Improvement of PSAP was noted even at 3 months after the discontinuation of the treatment. Conclusions-Fluoxetine is efficacious in the treatment of PSEI and PSAP. Its effect on PSD is not solidly confirmed.(Stroke. 2006;37:156-161.)

Discriminative sensory disturbances, which often occur bilaterally in some modalities, are common in patients with unilateral stroke even in those with intact sensory function on routine examination. The subtle disturbances of this sensation may explain, at least in part, the clumsiness of the patients that is not readily explained by conventional neurological tests.

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. Poststroke 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 poststroke fatigue and to develop better treatments for this condition.
