BBC World Service - Science In Action, Long Covid ‘brain fog’

New insights into the cause of Long Covid ‘brain fog’

New insights into cause of Long Covid brain fog.  Plus asteroid Bennu, Malaysian farmers helping plant conservation biology, and a new theory explaining the rise of the dinosaurs.

Following a bout of Covid-19, a significant number of people suffer with weeks or months of 'brain fog' - poor concentration, forgetfulness, and confusion.   This is one of the manifestations of Long Covid.  A team of scientists in the United States has now discovered that infection in the lung can trigger an inflammatory response which then causes patterns of abnormal brain cell activity.  It’s the kind of brain cell dysregulation also seen in people who experience cognitive problems following chemotherapy for cancer.

Also in the programme, the latest discoveries about the asteroid Bennu from the Osiris Rex mission, how Malayasian farmers led US researchers to a botanical discovery, and a new explanation for why dinosaurs took over the world 200 million years ago.
