Delirium, rare brain inflammation and stroke linked to Covid-19

International Edu News

Neurological complications of Covid-19 can include delirium, brain inflammation, stroke and nerve damage, finds a new UCL and UCLH-led study. The research team identified one rare and sometimes fatal inflammatory condition, known as ADEM, which appears to be increasing in prevalence due to the pandemic. Some patients in the study did not experience severe respiratory symptoms, and the neurological disorder was the first and main presentation of Covid-19.

The study provides a detailed account of neurological symptoms of 43 people (aged 16-85) treated at the National Hospital for Neurology and Neurosurgery, UCLH, who had either confirmed or suspected Covid-19. The virus causing Covid-19, SARS-CoV-2, was not detected in the cerebrospinal brain fluid of any of the patients tested, suggesting the virus did not directly attack the brain to cause the neurological illness. Further research is needed to identify why patients were developing these complications.

In some patients, the researchers found evidence that the brain inflammation was likely caused by an immune response to the disease, suggesting that some neurological complications of Covid-19 might come from the immune response rather than the virus itself.
