One in five vegetative patients might be conscious. Can we talk to them?

The idea of being trapped in one's own body without being able to communicate is, for some, just about the most terrible thing imaginable. ROUGHLY 20 percent of people in vegetative states appear to have some sort of conscious awareness But this scenario i

用fMRI与植物人交流

植物人状态是受到严重脑外伤昏迷后,虽然苏醒但仍然没有意识的状态 (Vegetative State, VS)。比植物人状态稍轻微一点的状态是最小意识状态 (minimally conscious state, MCS)。在最小意识状态,病人偶尔会显示出对外界刺激的反应,但这种反应并不一致。在临床上对病人意识状态的诊断通常只能通过病人的行为反应进行判断,比如病人是否会对外界刺激进行反应。这就可能出现一个很可悲的状况,如果一个病人存在意识,但是丧失了运动能力,他同样无法对医生的刺激进行反应。这时我们仍然得把病

Brain scan finds vegetative state patient conscious

A team led by neuropsychologist Dr Adrian Owen has reported on a patient who supposedly fulfilled all the criteria for a diagnosis of persistent vegetative state (PVS) but was found to have conscious awareness. This seems a little confusing to me, as PVS
