We leveraged modern neuroimaging techniques to estimate brain age and computed a proportional difference between chronologic age and estimated brain age. Multiple linear regression models were used to evaluate the relationship between proportional brain age difference (PBAD) and behavior.Results Participants (N = 93, 58 males and 35 females, average age = 61 years) had estimated brain ages ranging from 14 years younger to 23 years older than chronologic age. Advanced brain age predicted performance on semantic tasks (PPTT) and language tasks (WAB-R). For participants with advanced brain aging (n = 47), treatment gains (improvement on the PNT) were independently predicted by PBAD (T = −2.0474, p = 0.0468, 9% of variance explained).Discussion Through the application of modern neuroimaging techniques, advanced brain aging was associated with aphasia severity and performance on semantic tasks. Notably, therapy outcome scores were also associated with PBAD, albeit only among participants with advanced brain aging. These findings corroborate the importance of brain age as a determinant of poststroke recovery and underscore the importance of personalized health factors in determining recovery trajectories, which should be considered during the planning or implementation of therapeutic interventions.TE=echo time; TI=inversion time; PBAD=proportional brain age difference; PNT=Philadelphia Naming Test; PPTT=Pyramids and Palm Trees Test; POLAR=Predicting Outcomes of Language Rehabilitation in Aphasia; TR=repetition time; WAB-AQ=Western Aphasia Battery–Aphasia Quotient; WAB-R=Western Aphasia Battery–Revised; WAIS=Wechsler Adult Intelligence Scale
