Task: Answer Verification
Input (English): Question: Does severe leukoaraiosis portend a poor outcome after traumatic brain injury?
Answer: We provide first evidence that preexisting cerebral small vessel disease independently predicts a poor functional outcome after closed head TBI. This association is independent of other established outcome predictors such as age, comorbid state as well as intensive care unit complications and interventions. This knowledge may help improve prognostic accuracy, clinical management, and resource utilization.
Output (English): yes
