That’s what I was thinking, too.
JMO, but I would think there have to already be a disruption in the blood brain barrier to allow these particles to get through in the first place.
I’m having a hard time believing this one, considering it was only a few years ago that the Pittsburgh Compound was confirmed as the first successful chemical to cross the blood brain barrier. It was a big deal because this is the first step in being able to develop treatments to remove the plaque from Alzheimer’s brains.. you can’t remove the plaque if you can’t cross the barrier.
Now they are claiming that we’ve had random chemicals doing this all along???? I dunno, this sounds fishy to me.
