刘海若不是脑死亡 凌锋教授赴英会诊有结果 2002年05月20日17:04 北京晚报 • 前往英国为凤凰卫视记者刘海若会诊的北京宣武医院凌锋教授昨天下午1时3分返京。据凌教授介绍:刘海若的伤情已有转机,目前有自主呼吸,不是脑死亡。 • 宣武医院神经外科主任凌锋教授与英国的医生一起检查了刘海若的全身状况,并仔细讨论了病历及CT片。 凌教授认为,刘海若已有自主呼吸,另外对刺激有收缩反应,并且有咳嗽,这些都证明她不是“脑死亡”,生存下来是可能的。
刘海若苏醒创医学奇迹 八方援手力催凤凰重生2002年08月16日每日新报 • 三个月前在英国因车祸陷入昏迷的凤凰卫视女主播刘海若,不久前已在北京宣武医院恢复神志。 • 8月上旬,海若已经可以清晰地做出各种表情反应了,当医生说出数字时,海若已经能用手比划出动作了。主治医生凌锋表示,海若的病情有了质的变化,虽然距离正常人反应的灵敏程度还相差很远,但她已经不是植物人了,确切地说———海若已经醒了。
Ⅰ.Consciousness • the state of the patient’s awareness of self and environment and his responsiveness to external stimulation and inner need.
Content of consciousness • Orientation • percepbility • attitudes • emotions • active
Structural basis • 1.ascending reticular activating system, ARAS reticular formation thalamus cerebral hemisphere alert state • 2.cortex
Ⅱ clinical manifestation 1.according to level of consciousness 2.according to content of consciousness
1.level of consciousness (1) Somnolent (2) Stupor (3) Coma lesser degree deep
stupor Can be roused only by vigorous and repeated stimuli, when left unstimulated they quickly drift into a sleeplike state.
coma • The patient who appears to be asleep and at the same time incapable of being aroused by external stimuli or inner need. • lesser degree coma: reflex (+) • Deep coma: no reaction of any kind is obtainable, corneal, pupillary, pharyngeal, tenden reflex (-)
2.content of consciousness Confusion Delirium Special Type Decorticated Syndrome Akinetic mutism
confusion • “clouding of the sensorium” • Inability to think with customary speed • Marked by some degree of inattentiveness and disorientation accompanied by illusions
Delirium state • Hallucination, hyperactivity • High fever, atropine overdose, alcohol
Decorticated syndrome • Neocortical death • ARAS is normal, arousal-nonarousal cycle • Open eyes, blink, swallow, eyes move • Coma, Show no signs of awareness of the environment or inner need • Vegetative state, decerebrate rigidity 12 in 45 awakened in 2 weeks, >3 month:PVS
Akinetic mutism • The term akinetic mutism has been applied to yet another group of patients who are silent and inert as a result of bilateral lesions of the anterior parts of the frontal lobes, leaving the intact of the motor and sensory pathways; the patient is profoundly apathetic, lacking to an extreme degree the psychic drive or impulse to action(abulia). The abulic patient registers most of what is happening about him and forms memories.
Ⅲ differential diagnosis Abulia Locked-in syndrome
abulia • The patient are silent and inert as a result of bilateral lesions of the anterior parts of the frontal lobe, leaving intact the motor and sensory pathways, the patient is lacking to an extreme degree the psychic drive or impulse to action.
Locked-in syndrome • Lesion of the ventral pons (basis pons) • Interrupts the corticobulbar and corticospinal pathways • depriving the patient of speech and the capacity to respond in any way except by vertical gaze and blinking • wakefulness
Ⅳ brain deathHarvard medical school committee1968 • 1. Absence of cerebral function • 2. Absence of brainstem function • including spontaneous respiration • 3. Irreversibility
Brain death • 1. Absence of cerebral function: Deep coma, total lack of spontaneous movement, and of motor and vocal responses to all visual auditory and cutaneous stimulation • 2. No spontaneous respiration • 3. Absence of brain stem function: Dilated midposition fixed pupils, corneal reflex, oculocephalic and oculovestibular test, gag reflex(-), last for 12 hours • 4. EEG: flat or isoelectric (<2μV) during a 30-minutes recording • 5. Spinal reflex may persist • 6. Exclude intoxication, hypothermia, metabolic disturbance
Section Ⅱ Aphasia, apraxia, agnosia
aphasia • A loss or impairment of the production and/or the comprehension of the spoken or written language due to an acquired lesion of the brain • No higher order mental function disturbance i.e. Confusion, delirium, mental retardation • Not dysarthria • Not aphonia
classification • 1.Parasylvian fissure aphasic syndrome Broca aphasia, Wernicke aphasia Conduction aphasia • 2.Transcortical aphasia Transcortical motor, sensory, mixed • 3.Global aphasia • 4.Anomic aphasia • 5.Subcortical aphasia syndrome thalamic aphasia, basal ganglion aphasia
Broca aphasia • Primary deficit in speech production • Dominant hemisphere • Inferior frontal gyrus, posterior portion
Wernicke aphasia • Primary deficit in comprehension • Paraphasia: literal: the grass is greel verbal: the grass is blue • Disturbance in repetition • Wernicke area: posterior portion of supratemporal gyrus
Transcortical aphasia • Watershed area • Repetition is remarkably preserved
Anomic aphasia • The patient lose only the ability to name people and objects • Middle temporal lobe
Global (Total) aphasia • Left middle cerebral artery occlusion • All aspects of speech and language are affected • Can say only a few words
Subcortical aphasia • Thalamic aphasia • Basal ganglion aphasia: nonfluent, dysarthric, paraphasic
apraxia • The term apraxia is applied to a state in which a clear-minded patient with no weakness, ataxia or other extrapyramidal derangement and no defect of the primary modes of sensation loses the ability to execute highly complex and previously learned skills and gestures.
apraxia • Ideomotor apraxia • Ideational apraxia • Melokinetic apraxia • Constructional apraxia • Facial-oral apraxia • Dressing apraxia
agnosia • A highly-ordered perceptual disturbance, no elementary sensation disturbance, can not interpret sensations correctly. • Due to disorders of the association areas in the parietal lobes.
agnosia • Visual agnosia: object, face, verbal • Auditory agnosia: verbal • Sensory agnosia • Body image disturbance non-dominant parietal lobe • Gerstmann syndrome finger agnosia, right-left confusion, dysgraphia, Dyscalculation Dominant hemisphere angular gyrus
