Article Synopsis
- * The majority of the patients had severe COVID-19, with 90% showing abnormal ASL perfusion, particularly hypoperfusion in the temporal poles and frontal lobes, even if traditional MRI scans appeared normal.
- * The findings highlight that over 80% of these patients exhibited significant brain perfusion deficits, suggesting that neurological complications in COVID-19 can occur independently of visible lesions on standard MRI scans.
Article Synopsis
- Background: The study examines brain MRI abnormalities in patients with severe COVID-19 (SARS-CoV-2) and identifies potential neurological issues related to the virus.
- Methods: Researchers analyzed data from 37 hospitalized patients who had neurological symptoms and abnormal brain MRIs between March and April 2020, excluding cases with ischemic strokes or unrelated chronic lesions.
- Results: The patient cohort, primarily older men, exhibited various neurological symptoms, with MRI findings showing significant abnormalities in brain regions including the medial temporal lobe and evidence of microhemorrhages, suggesting COVID-19's impact on brain structure.
