Due to their young age young stroke survivors have to cope with a dramatic impact on their life for the decades to come. We investigated the sex-specific very long-term functional outcome after transient ischemic attack (TIA) and ischemic stroke (IS) in adults aged 18-50 years. This study is part of a cohort study among 619 first-ever young ischemic stroke patients, admitted to our department between January 1, 1980 and November 1, 2010. Functional outcome was assessed during follow-up in 2009-2011 and in 2014-2015 with the modified Rankin Scale (mRS) and instrumental Activities of Daily Living scale (iADL). Risk factors for a poor functional outcome (mRS > 2 and iADL < 8) were calculated by logistic regression analysis. After a mean follow-up of 13.9 (SD 8.2) years, 24.5 % of TIA patients and 44.7 % of IS patients had a poor functional outcome (mRS > 2). When assessing the survivors, 15.2 % of TIA patients and 22.9 % of IS patients had a poor outcome as assessed by iADL. The strongest baseline predictors of poor outcome were female sex (OR 2.7, 95 % CI 1.5-5.0) and baseline NIHSS (OR 1.1, 95 % CI 1.1-1.2 per point increase). In conclusion, 14 years after an ischemic cerebrovascular event in young adults, one out of five IS survivors and one out of ten TIA survivors is still dependent in daily life, with a two to threefold higher risk of a poor outcome in women. This includes a period of life, during which important decisions regarding work and family life have to be made.
