COVID-19如何傷害大腦、造成譫妄、失智與行為改變(Nature. 2020 Dec;588(7836):22-24.)

from 探索大腦的會談地圖 · host 林煜軒醫師

據統計在加護病房治療的COVID-19的患者高達55%有「譫妄」(delirium),這比一般急重症患者31.8%有譫妄的比例高出許多。   「譫妄」突然在短時間內有起起伏伏的意識狀態改變、認知功能障礙,甚至是行為問題。然而譫妄是一種「急性大腦衰竭」的現象,是內外科疾病最終的表現,不是原發性精神疾病。   「譫妄」後會增加2.3倍罹患失智症的風險,在Lancet Psychiatry的大型研究也指出65歲以上的COVID-19患者中有1.6%在感染14-90天診斷為失智症。因此在COVID-19疫情的另一個影響,是失智的患者會不會也增加許多?   這集的podcast整理7篇國際頂尖期刊Nature, JAMA Psychiatry, Lancet Psychiatry的研究,解說新型冠狀病毒侵犯大腦的神經途徑,傷害大腦的病理機制,以及大型的流行病學實證研究。   對「譫妄」的基本介紹,也可以參考以下資訊圖表   參考論文: 1.    Could COVID delirium bring on dementia?
