Cognitive Functioning in TBI Patients: A Review of Literature

Traumatic brain injury (TBI) is a major public health problem. Patients with mild, moderate and severe brain injuries suffer from physical, behavioral emotional and social problems. Beside these problems persons with TBI experience serious long enduring problems with cognitive functioning. In the present study an attempt was made to review the literature on cognitive functioning in mild moderate and severe TBI patients. The aim of the study was to review the literature related to whether cognitive functioning is affected in mild moderate and severe TBI patients and if affected what are the areas of cognitive functioning affected in mild moderate severe TBI patients. Studies conducted on cognitive functioning with respect to TBI suggest that there is a decline in the cognitive functioning of TBI patients. On reviewing the available literature pertaining to cognitive functioning in mild, moderate and severe TBI patient It was found that studies lacks consensus and further research is needed to resolve the contradiction.
