Definition 意识一一机体对自身及外界环境感知并能作出正 确反应的状态。 意识障碍一一机体对外界环境的刺激缺乏反应 的一种病理状态。 昏迷一一是严重的意识障碍，其主要特征为随意 运动丧失，对外界刺激失去正常反应并出现病理 反射活动
Definition 意识－－机体对自身及外界环境感知并能作出正 确反应的状态。 意识障碍－－机体对外界环境的刺激缺乏反应 的一种病理状态。 昏迷－－是严重的意识障碍，其主要特征为随意 运动丧失，对外界刺激失去正常反应并出现病理 反射活动
判断意识障碍程度disturbance of consciousness 区分嗜睡、意识模糊、昏睡、昏迷 嗜睡somnolence：病人呈持续睡眠状态，但可被轻度刺激 唤醒，醒后能正确简单回答问题，但反应迟钝。 意识模糊confusion：病人对时间、地点、人物的定向能力 发生障碍，思维混乱，可有错觉、幻觉、精神错乱、谵 妄等表现。 昏睡stupor：病人处于沉睡状态，仅能被压眼眶、用力摇 动身体等较强刺激唤醒。 昏迷coma:是最严重的意识障碍

Summary: Disturbance of consciousness is impediment() of having an awareness of one's environment and one's own existence,sensations and thoughts. According to the degree of disturbance of consciousness,it can be divided:somnolence, confusion,stupor,coma

What is Coma and Persistent Vegetative State? A coma is a profound or deep state of unconsciousness.An individual in a state of coma is alive but unable to move or respond to his environment.Coma may occur as a complication of an underlying illness,or as a result of injuries,such as head trauma

A persistent vegetative state "brain-death") sometimes follows a coma.Individuals in such a state have lost their thinking abilities and awareness of their surroundings,but retain non-cognitive function and normal sleep patterns.Even though those in a persistent vegetative state lose their higher brain functions,other key functions such as breathing and circulation remain relatively intact.Spontaneous movements may occur, and the eyes may open in response to external stimuli.They may even occasionally grimace(痛苦的表情)，cry,or laugh
