[Cognitive Dysfunction Due to Traumatic Brain Injury].

Traumatic brain injury (TBI)-associated dementia refers to cognitive dysfunction resulting from brain injury caused by head trauma. With advances in medical care, the survival rate of TBI patients has increased. Additionally, the growing elderly population has led to a rise in cases of cognitive dysfunction following TBI. As a result, the assessment and management of such conditions have become urgent issues. Accurate diagnosis of TBI-related cognitive impairment requires objective evaluation, primarily through radiological neuroimaging. This paper provides an overview of cognitive dysfunction caused by traumatic brain injury and discusses relevant conditions encountered in neurosurgical practice.
