Risk factors for chronic covert brain infarction investigated

Chronic covert brain infarction is present in more than one-third of patients with a first-ever acute ischemic stroke (AIS), and these patients represents a vascular high-risk subgroup, according to new research findings presented at EAN 2021.

Dr Thomas Meinel and colleagues from Bern University Hospital, Switzerland, assessed the rate of chronic brain infarctions (CBI) in 1,546 consecutive patients with first-ever AIS on MRI, seen in 2015-2017, and investigated their phenotypes and diagnostic value.
