Summary

Post-stroke fatigue persists for 10 years, surprisingly linked to better cognitive function and daily independence. Early visuospatial skills predict long-term fatigue in stroke survivors.

Area of Science:

  • Neurology
  • Rehabilitation Medicine
  • Psychology

Background:

  • Post-stroke fatigue is a prevalent and debilitating condition affecting survivors.
  • Long-term data on fatigue and its relationship with cognitive and physiological factors post-stroke is limited.

Purpose of the Study:

  • To investigate the long-term trajectory of fatigue up to 10 years after stroke.
  • To explore the association between fatigue and cognitive/physiological parameters in young stroke survivors.

Main Methods:

  • A prospective cohort study of 38 young stroke survivors followed for 10 years.
  • Fatigue assessed using the Fatigue Assessment Scale (FAS).
  • Cognitive functions (global and sub-domains) assessed at multiple time points (1 week, 7 months, 10 years).

Main Results:

  • Over half of survivors experienced fatigue at 10 years, with a median FAS score of 25.
  • Higher fatigue correlated with greater independence, higher BMI, anxiety, and better cognitive function (global, working memory, visuospatial).
  • Visuospatial function at 7 months was the sole significant predictor of fatigue at 10 years (adjusted R² = 0.815).

Conclusions:

  • Post-stroke fatigue can persist for a decade, showing a dissociation from fatigability.
  • Early-phase visuospatial function is a key predictor of late-stage post-stroke fatigue.
  • Findings suggest a potential window for targeted rehabilitation and highlight the need for further clinical investigation.
