21例持续性植物状态（PVS）患者中潜伏期听觉诱发电位（ML－AEP）异常率为100％，证明ML－AEP对PVS具有较高的诊断价值，有助于确定脑干以上听通路的损害。同时证明ML－AEP波Na、Pa起源于颞叶及皮质下等结构。患者出现PMR可能提示其存在部分意识，两侧PMR存在可作为PVS意识恢复的标志，而两侧PMR消失可作为PVS辅助诊断的标准之一。
The abnormal rate of latent phase auditory evoked potential (ML-AEP) in 21 patients with persistent vegetative state (PVS) was 100%, which proved that ML-AEP had a high diagnostic value in PVS and could help to determine the damage of the auditory pathway above the brainstem . At the same time prove ML-AEP wave Na, Pa originated in the temporal lobe and subcortical structures. The presence of PMR in patients may suggest that there is some awareness, and the presence of PMR on both sides can be used as a sign of PVS consciousness recovery, and the disappearance of PMR on both sides can be used as one of the criteria for PVS-assisted diagnosis.
