Summary
Poststroke fatigue (PoSF) affects over half of stroke survivors and significantly impacts daily life, particularly physical activities. Pre-stroke fatigue is the strongest predictor of PoSF, alongside depression and stroke severity.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Psychiatry
Background:
- Poststroke fatigue (PoSF) is a prevalent yet under-researched complication following stroke.
- Understanding the characteristics and contributing factors of PoSF is crucial for patient management.
Purpose of the Study:
- To investigate the prevalence and key factors associated with poststroke fatigue (PoSF).
- To assess the impact of PoSF on patients' daily functioning.
Main Methods:
- A cohort of 220 stroke outpatients, studied at 15 months post-stroke.
- Assessment of PoSF, poststroke depression (PSD), prestroke fatigue (PrSF), and daily activity impact using validated scales.
- Multivariate analyses to identify independent predictors of PoSF.
Main Results:
- PoSF was present in 57% of patients; 38% reported prestroke fatigue (PrSF) and 24% had poststroke depression (PSD).
- Prestroke fatigue (PrSF), high modified Rankin Scale (MRS) scores, and PSD were independently associated with PoSF.
- PoSF significantly impacted physical daily activities more than psychological or cognitive domains.
Conclusions:
- Fatigue is a common and impactful sequela of stroke, particularly affecting physical function.
- Prestroke fatigue (PrSF) is the most significant predictor of PoSF, followed by stroke severity and PSD.
- Individualized treatment strategies are recommended, considering the multifactorial nature of PoSF.
