Abstract:
Changes of ABR and LEDVEP in 60 patients with mild head injury and of ABR LEDVEP BEAM in 40 out of 60 patienites were studied. The results were as folls:we:①The Chief abnormality of ABR. was the prolongation of Ⅰ- Ⅲ interpeak latency ②The appaent abnomality of the LEDVEP was the prolongation of N70 latency and the drop of N70-P100 amplitude ③The characteristic change of BEAM was the incre ment of average ?1 power. The increment of ?/?2 power ratio suggested the presence of supertentorial lesions.According to the follow up study of clectrophysiological findings, a scale of brain dysfunction was created,It provides an objective criterion for clinical diagnosis and prognostic determination. In forensic practicl. Grade O and Ⅰ could be considered as minimal wound and Grade Ⅱ as slight wound,
