The linked CNN article is a very poor summary. It doesn't even include a proper citation, and the link to the study isn't directing to the one being discussed!? Come on, CNN.

I recommend reading the editorial in Stroke instead: https://www.ahajournals.org/doi/pdf/10.1161/STROKEAHA.119.02...

And you can get the article here if you have access to Stroke: https://www.ahajournals.org/doi/10.1161/STROKEAHA.118.023100
