AbstractAphasia is an acquired language impairment associated with damage to the language-dominant hemisphere. In this study, aphasia recovery outcomes were examined from 73 individuals who participated in aphasia treatment over extended periods of time. Aphasia quotient (AQ) scores attained from the Western Aphasia Battery (WAB) were used as measurement of language change as well as classification of severity for all individuals. Across all participants, language performance improved an average of +5.62 AQ points over about four years. The slope of the recovery curve for the entire population was positive and significant. When participants were examined relative to aphasia severity, those in the moderate category showed the most improvement over time with an average increase of 11.68 AQ points. Age at the time of aphasia onset was a significant predictor of improvement in language performance as measured by the WAB, suggesting that younger individuals have a better prognosis for continued improvement over the years following the event. The findings from the study indicated that many individuals continue to improve even at relatively long times post onset, and that significant language gains can be made regardless of the amount of time passed, especially when the recovery process is not complicated by the effects of advanced age.
