摘要:

越来越多的重度脑损伤患者伴有严重意识障碍,准确客观地评估他们的脑功能及预后亟待解决。在意识障碍患者中,事件相关电位P300潜伏期延长,振幅降低,可反映患者的残余认知功能;P300振幅和潜伏期的动态变化可用于判断认知功能的恢复程度;特殊的刺激形式产生的P300可能对于区分植物状态和最小意识状态有一定价值。

Abstract:

Severe brain-injured patients would suffer severe disorders of consciousness for a long time. It is needed to prognose their brain function and outcomes. P300 wave of event-related potentials may feature as long latency and short amplitude in disorders of consciousness, which respond to the residual cognitive function. The dynamic changes of P300 wave amplitude and latency can be used to determine the recovery of cognitive function. The P300 waves induced by special stimulus may help to differentiate the vegetative state from the minimally conscious state.

Key words: event-related potentials, P300, disorders of consciousness, review
