[Forensic application of brainstem auditory evoked potential in patients with brain concussion].

ABSTRACT

OBJECTIVE: To investigate changes of brainstem auditory evoked potential (BAEP) in patients with brain concussion. METHODS: Nineteen patients with brain concussion were studied with BAEP examination. The data was compared to the healthy persons reported in literatures. RESULTS: The abnormal rate of BAEP for patients with brain concussion was 89.5%. There was a statistically significant difference between the abnormal rate of patients and that of healthy persons (P<0.05). The abnormal rate of BAEP in the brainstem pathway for patients with brain concussion was 73.7%, indicating dysfunction of the brainstem in those patients. CONCLUSION: BAEP might be helpful in forensic diagnosis of brain concussion.
