The effect of fatigue syndrome on cognitive functioning and quality of life of a patient after an ischemic stroke
Acta Medica Saliniana(2017)
Abstract
Background: Fatigue is usually defined as a subjective lack of physical and/or mental energy necessary for doing everyday activities. Fatigue is a subjective condition, and there is not a valid definition of fatigue after a stroke at the moment. Aim: The analysis of frequency of fatigue syndrome in 200 patients after an ischemic stroke and its effect on cognitive functioning and quality of life after an ischemic stroke was conducted. The measuring instruments for the assessment of fatigue used were the Chalder Fatigue Scale, for cognitive functioning the Mini-Mental State Examination, and for the quality of life SF-36, scale for measuring quality of life. Neurological and neuropsychological testings of the participants were conducted three months after an ischemic stroke – first testing, six months after an ischemic stroke – second testing, and twelve months after an ischemic stroke – third testing. Results: Fatigue syndrome was noted in 68% of the patients three months after an ischemic stroke, in 71% in testing after six months, and 70% after twelve months. The mean values of MMSE score in the patients with and without fatigue syndrome was between 28 and 29 in all testings, which indicates that they had normal cognitive functioning. The significance of differences in the MMSE score in the patients with and without fatigue syndrome in the first, second and third testing was tested using HI-squared test and the results showed that there were no statistically significant differences (p>0.005). In comparison of quality of life between the patients with and without fatigue the results showed that the patients without fatigue syndrome had significantly better quality of life in comparison with the patients with fatigue syndrome in the field of mental and physical health (p< 0.0001). Conclusion: Fatigue syndrome after an ischemic stroke has a significant frequency (68-71%) and duration. Fatigue syndrome does not affect cognitive functioning of patients after an ischemic stroke but it leads to impaired quality of life of patients in all areas.
