(Zahra Taheb/ Science Alert) — A new study that drew on data gathered by UK Biobank suggests COVID-19 survivors may suffer from a loss of gray matter over time.
The long-term experiment, which involved 782 volunteers, compared brain scans of individuals before the pandemic. For an analogy between pre-pandemic and post-pandemic brain scans, researchers then invited 394 COVID-19 survivors to return for follow-up scans, as well as 388 healthy volunteers.
Among those participants who recovered from COVID-19, researchers saw significant effects of the virus on human cerebral matter, with a loss of gray matter in regions of the brain. (…)
