Covid-19 linked brain damageDate: 10 July 2020 Tags: Miscellaneous
Scientists have warned of a potential wave of coronavirus-related brain damage that can lead to severe neurological complications, including inflammation, psychosis and delirium.
A study by researchers described 43 cases of patients with COVID-19 who suffered either temporary brain dysfunction, strokes, nerve damage or other serious brain effects.
The research adds to recent studies which also found the disease can damage the brain.
Scientists are expecting an epidemic on a large scale of brain damage linked to the pandemic perhaps similar to the encephalitis lethargica outbreak in the 1920s and 1930s after the 1918 influenza pandemic.
COVID-19, the disease caused by the new coronavirus, is largely a respiratory illness that affects the lungs, but neuroscientists and specialist brain doctors say emerging evidence of its impact on the brain is concerning.
During the course of study, the patients who had brain inflammation were diagnosed with a rare condition called acute disseminated encephalomyelitis (ADEM) which is more usually seen in children and can be triggered by viral infections.
Since the disease has only been around for a matter of months, we might not yet know what long-term damage COVID-19 can cause.
Doctors need to be aware of possible neurological effects, as early diagnosis can improve patient outcomes.
The emerging evidence underlined the need for large, detailed studies and global data collection to assess how common such neurological and psychiatric complications were.
