Emotional processing deficits have a significant negative impact on the lives of persons with TBI. There is emerging research indicating that, in addition to cognitive and behavioral impairments, social and emotional difficulties following TBI are common and are related to significant problems in social relationships, poor social participation, impaired empathy, and a high degree of caregiver stress. Emotional processing is a critical component of social cognition, including the abilities to both identify and discriminate basic universal emotions. The stability of emotional processing deficits following TBI indicates that these impairments likely impact individuals with TBI consistently across the lifespan, and do not appear to resolve with time.
