Abstract Number: Esoc2026a1139 Fatigue in Men and Women 3 and 12 Months After Ischemic Stroke: Occurrence, Severity, Impact on Everyday Life, and Changes Over Time

Abstract Background and aims Although fatigue is common after stroke, up-to-date knowledge about gender-specific differences in severity, impact on daily life, and persistence over time is limited. Here, we investigated the occurrence, severity, and impact of fatigue at 3 and 12 months after first-ever ischemic stroke, including changes over time and sex differences. Methods Participants were consecutively included in the Lund Stroke Recovery Study at Skåne University Hospital, Sweden, between 2021 and 2023. Self-reported fatigue was assessed by the Swedish Fatigue Assessment Scale (S-FAS) at 3- and 12-months post-stroke. S-FAS total scores ≥24 indicate fatigue; 24-35 = moderate fatigue, 36-50 = severe fatigue (range 10-50). Results Two hundred sixty-eight participants (91 women, median age 73) were included. At 3- and 12-months, fatigue (S-FAS ≥24) was reported by 30% and 28% of the men, and by 46% and 42% of the women. Moderate fatigue was most common in both sexes at both timepoints. The problems most frequently reported among both sexes were being bothered by fatigue, getting tired very quickly, and not doing much during the day. Overall, fatigue decreased significantly over the first year in both men (S-FAS median score from 31 to 27, P = 0.037) and women (S-FAS median score from 30 to 27, P = 0.007). Conclusions Fatigue is common after first-ever ischemic stroke, particularly in women, and affects daily life negatively. Although fatigue decreased over the first year, it was still prevalent at 12 months in several individuals. Reassessment of both fatigue severity and its consequences over time is crucial in order to provide person-centered rehabilitation interventions.
