Re:肝性脑病
很好的文章!
*******
现在臨床上还有人應用核醫(nuclear medicine)来诊断此病:
利用Single-Photon Emission Computed Tomography (SPECT) Brain Imaging臨床應用:
急性 CVA & TIA 的診斷: CVA 病患一旦發作, brain SPECT 檢查可立刻發現腦部局部血流之變化,故可在急性期 brain CT negative 之病人做確定診斷.
協助鑑別診斷失智症,如 Alzheimer's disease, multi-infarct dementia, vascular dementia, pseudodementia, etc.
定位癲癇的病灶了解腦炎之腦部血流變化,幫助定位病灶,評估預後可協助了解精神病患之腦部血流變化,病生理機轉,協助各種精神疾病之鑑別診斷和評估預後.
其他方面,還可以協助 toxic/hepatic encephalopathy, SLE 對中樞神經系統的侵犯等之診斷及確定病灶的部位.

肝性脑病, 肝昏迷一般可分为4个级别:

以前曾贴过,目前还有人认为在肝炎或肝病期间还会出现一种现象"脑雾",即脑性肝病的前期或微型.现象一般有:
waking up mad, saying angry things upon awakening, and then not remembering saying them
睡醒后生气,说一些愤怒的事情之后又不记得说过;
saying or doing irrational things, and not remembering
说或做一些不应该做的事情之后不记得干过;
dozing off while eating your dinner...
吃饭时犯困...
dozing off while putting on your shoes and ready to go out...
穿鞋出门时忽然想睡觉...
getting up out of bed, and taking several quick steps sideways until you bump into the wall...
从床里爬起来,站不稳象螃蟹一样跌跌撞撞横着走多步直到撞到墙壁上...
suddenly not knowing your address...
一下不记得自己住址...
suddenly not knowing your phone number...
忽然不记得自己电话号码...
wanting to stay in bed a few days, and if someone wakes you, getting mad and saying things...and later you swear it didn't happen...
想赖床几天,如果有人叫你,你会发怒并骂三字经...事后你会发誓没干过...
looking normal, but saying something off the wall...and later you swear it didn't happen...
看上去正常,可是有时会对墙壁讲话,之后你又不承认了...
slurring your words...
讲话不清楚...
wanting to sleep all day everyday...
想睡整天...
********
自己检查脑雾,肝性脑病:
闭上双眼,坐直,双手前平伸,五指分开,手心向外,让家人,朋友帮你看双手是否发抖,如没有为正常,如果可注意检查,不过要和甲状腺机能抗进分开来.
