Human brain's cerebellum affected more than other regions from Covid: Study

The human brain's cerebellum might be more vulnerable to Covid infections than other brain regions, a new study employing an innovated MRI technique has found.

The study from Rotman Research Institute and Sunnybrook Hospital in Toronto, Canada, reinforces the idea that Covid can lead to changes in the brain, it said.

The new imaging technique, called correlated diffusion imaging (CDI), was developed by Alexander Wong, a systems design engineering professor, University of Waterloo, Canada.

A new form of MRI, CDI can better highlight the differences in the way water molecules move in tissue by capturing and mixing MRI signals at different gradient pulse strengths and timings, the study published in the journal Human Brain Mapping said. Wong had previously developed CDI as a better imaging measure for detecting cancer.

The CDI imaging of frontal-lobe white matter (in the brain's cerebrum) revealed a less restricted diffusion of water molecules in COVID-19 patients. At the same time, i
