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
