Tulane study shows COVID-19’s lingering impacts on the brain April 01, 2022 COVID-19 patients commonly report having headaches, confusion and other neurological symptoms, but doctors don’t fully understand how the disease targets the brain during infection. covid 確診病患常有頭痛和其他神經系統症狀但目前不完全瞭解病毒如何影響腦部 researchers at Tulane University have shown in detail how COVID-19 affects the central nervous system, according to a new study published in Nature Communications. The findings are the first comprehensive assessment of neuropathology associated with SARS-CoV-2 infection in a nonhuman primate model. 杜蘭大學研究人員展示病毒影響中樞神經系統這是首次在非人類靈長類對 covid 病毒的神經病理學研究發表在 Nature Communications 自然通訊期刊 The research team found severe brain inflammation and injury consistent with reduced blood flow or oxygen to the brain, including neuron damage and death. Microhemorrhages, or small bleeds in the brain, were also present. 發現嚴重的腦部發炎往腦部血流量及氧氣輸送減少包含神經元損傷和死亡還有腦部的微量或少量出血 Surprisingly, these findings were seen in subjects that did not experience severe respiratory disease from the virus. 驚訝的是這些症狀在沒有嚴重呼吸道疾病的感染個體也有出現 “Because the subjects didn’t experience significant respiratory symptoms, no one expected them to have the severity of disease that we found in the brain, ” Fischer said. “But the findings were distinct and profound, and undeniably a result of the infection.” 感染個體沒有明顯呼吸道症狀沒人預期腦部會有嚴重疾病但這些發現是獨特的不可否認是感染造成的 The findings are also consistent with autopsy studies of people who have died of COVID-19, suggesting that nonhuman primates may serve as an appropriate model, or proxy, for how humans experience the disease. 這些發現也與 covid 感染死亡的人類驗屍結果一致顯示非人類靈長類可替代人類做為研究疾病模型 Neurological complications are often among the first symptoms of SARS-CoV-2 infection and can be the most severe and persistent. They also affect people indiscriminately — all ages, with and without comorbidities, and with varying degrees of disease severity. 神經系統症狀經常是第一個 covid 感染症狀而且可能是最嚴重及持久的而且它不挑人年齡有無共病症輕重症都有機會 Fischer hopes that this and future studies that investigate how SARS-CoV-2 affects the brain will contribute to the understanding and treatment of patients suffering from the neurological consequences of COVID-19 and long COVID.
