[Empathy disorders in traumatic brain damage]

Social cognition is a complex theoretical concept that includes many great high level mental functions. Within this concept is included the empathy, which is so significant and relevant to be evaluated separately but it has been one of the least studied areas in traumatic brain injury.

A large sample of patients with a traumatic brain injury has been studied. The aim was to evaluate the decrease of the empathic ability. One of the validated instruments in our area has been used: the Interpersonal Reactivity Index. The study has been completed by using partially the Eslinger's social executors model as we consider that clinic display of the empathic response changes observed in those with a traumatic brain injury are influenced by previous personality and other different factors.

With regard to the percentage of empathic ability decrease our results are similar to those documented in the few existing studies on this subject. According to the results the Eslinger's social executors model has been confirmed as a suitable model to carry out a longitudinal and analytical study of neuropsychiatric disorders like the empathy. We have realized that the empathic ability in traumatic brain injury is modulated by previous personality and intelligence. Finally, right hemisphere traumatic damage could be a warning signal in posttraumatic social cognition changes.
