Patients in a coma show complete disability in the arousal system and fail to achieve awareness spontaneously; yet true coma represents a transient state and rarely lasts longer than a month [1]. The VS （also known as unresponsive wakefulness syndrome）, characterized as a state with spontaneous or stimulus-induced eye-opening but the patient appears totally unaware of self and environment, may persist for months or years [2]. In contrast, the MCS is evidenced by preserved and reproducible signs of awareness as well as sleep-wake cycles, suggesting better recovery than coma and VS. Considering that no signs of consciousness are detectable, patients in a VS suffer from a high rate of misdiagnosis [3].展开更多
