Health-Related Quality of Life and Fatigue After Transient Ischemic Attack and Minor Stroke

Abstract

BackgroundStudies suggest that fatigue and cognitive impairment may be present after transient ischemic attack (TIA) or minor stroke, but little is known about consequences in daily life. The main aim was to explore the presence of fatigue, cognitive impairment, and consequences in daily life after minor stroke-TIA. MethodsPatients (n = 92) were consecutively recruited from the Stroke Unit and were assessed within 2 weeks of hospital admission for first-ever and 3 months later. Control participants (n = 89) were recruited from the same population as the patients. Measures included the Fatigue Assessment Scale (FAS), Montreal Cognitive Assessment (MoCA), and The European Quality of Life index (EQ-5D-5L). ResultsThe prevalence of substantial fatigue was 65.2% (confidence interval [CI] 95%: 54.6%-74.8%) and extreme fatigue was 20.7% (CI 95%: 12.9%-30.4%) in minor stroke-TIA patients. The prevalence of substantial fatigue in controls was 23.5% (CI95%: 15.0%-34.0%) and extreme fatigue was 4.5% (CI 95%: 1.8%-11.0%). The mean (SD) score on the MoCA was 24.1 (3.2) for the patients group and 27.3 (2.4) for controls (P < .001). FAS showed the strongest negative correlation score with the EQ-5D-5L index (r = −0.480; P < .0001), higher levels of mental and physical fatigue are associated with lower EQ-5D-5L index (r = −0.376; P < .001 and r = −0.497; P <.001, respectively). The correlations between the FAS and the MoCA measures were no significant. MoCA was not significantly correlated with EQ-5D-5L. ConclusionsFatigue was a very common symptom in TIA/minor stroke patients. The fatigue had a significant impact on the health-related quality of life construct in its entirety, even after accounting for the influence of several factors.
