Deficits in social cognition are common after traumatic brain injury (TBI).
However, little is known about how such deficits affect functional outcomes. The
purpose of this study was to investigate the relationship between social
cognition and functional outcomes in patients with TBI. We studied this
relationship in 20 patients with TBI over the course of 1 year post-injury.
Patients completed neurocognitive assessments and social cognition tasks. The
social cognition tasks included an emotion-perception task and three theory of
mind tasks: the Faux Pas test, Reading the Mind in the Eyes (Eyes) test, and the
Moving-Shapes paradigm. The Craig Handicap Assessment and Reporting Technique was
used to assess functional outcomes. Compared with our database of normal
subjects, patients showed impairments in all social cognition tasks. Multiple
regression analysis revealed that theory of mind ability as measured by the Eyes
test was the best predictor of the cognitive aspects of functional outcomes. The
findings of this pilot study suggest that the degree to which a patient can
predict what others are thinking is an important measure that can estimate
functional outcomes over 1 year following TBI.
