Theory of mind impairment after severe traumatic brain injury and its relationship with caregivers' quality of life.

Purpose: Theory of mind (ToM) deficits are common consequences of severe Traumatic Brain Injury (sTBI), but little is known about their impact on patients' and their caregivers' quality of life. This study aimed (i) to examine the presence of ToM difficulties in individuals with sTBI and adequate levels of self-awareness (SA); (ii) to investigate their relationship with perceived Health Related Quality of Life (HRQoL) in patients and their caregivers.

Methods: Twenty individuals with sTBI and adequate levels of SA, and 20 healthy controls (HCs) were recruited.
