Abstract

Neurobehavioral deficits, especially in cognition, are often the cause of significant disability after traumatic brain injury (TBI). A thorough evaluation of cognitive function is needed before an effective cognitive rehabilitation. Common cognitive changes that follow TBI include impaired attention, psychomotor slowing, executive dysfunction, and impairment in working memory. The Seoul Neuropsychological Screening Battery (SNSB), the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) and the Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-cog) can be used to evaluate the multiple cognitive domains in TBI. Wisconsin Card Sorting Test, Frontal Assessment Battery, Trail making test, Digit-symbol test and symbol-digit test are useful to detect mild cognitive impairment in the TBI patients who have subjective cognitive impairment and no abnormality on routine neuropsychological tests. Tests of psychomotor speed and executive function are sensitive to TBI. Computerized neurocognitive testing can be administered to measure relatively mild degrees of neurocognitive impairment in TBI.
