Abstract

The current study explored the interplay between stroke, language, and the stress biomarker, cortisol, in individuals with aphasia (IWA) and individuals with right brain damage (RBD). Nineteen IWA following a left-hemisphere stroke and 12 RBD participants began the study between one to six months post-stroke and were followed for three months. Language skills were assessed monthly; afternoon salivary cortisol samples were collected biweekly. Individuals with aphasia showed improvements in language test scores, however, language was not associated with afternoon salivary cortisol levels.  The RBD group demonstrated fairly unchanging test scores, but naming ability did relate to salivary cortisol levels.
