47 10 Full Breakdown

Summary

Story summary

Researchers reviewed 49 MRI studies that compared COVID-19 patients with healthy controls.
The review found abnormal white-matter diffusion suggesting myelin damage even in mild cases.
It also identified gray-matter loss and cortical thinning in the frontal, temporal and parietal lobes of recovered patients.
Authors note reliance on cross-sectional data without baseline scans and call for unbiased longitudinal whole-brain research.
