Objective: Cognitive and behavioral disturbances after traumatic brain injury (TBI) are not uncommon in clinical practice. Although the neurobehavioral consequences following TBI are richly documented in the western literature, studies on this topic in Taiwan are still limited in scope and number. Method: The present article first reviews the cognitive problems after head traumas, including deficits in information processing, memory, and executive functions. Meanwhile, emotional and behavioral disturbances, such as the disinhibition and apathy syndromes that occur after trauma, are also discussed. Results: There is a variety of neurobehavioral disturbances after TBI, which can be severely detrimental to the patient's social and occupational functioning. Conclusion: There is a necessity to establish a comprehensive assessment of neuropsychological deficits following TBI in Taiwan, with linkage to cognitive and/or behavioral remediation.
