Paula,
Thanks so much. At last they are doing more work on the BBB, and admitting not enough has been done. Professor Leenders in Holland is my first reference. He is doing excellent work.
The big question is what can be done about it. You can have a faulty heart replaced, but a drefective blood brain barrier!!!. The only things you could do is 1. Avoid the things that opens the BBB further, eg stress.
2. Take supplements that tighten the pores, eg curcumin, alpha lipoic acid,
3. Remove the toxins that are in the bloodstream, or their means of generation, eg helicobacter P, detox heavy metals.
Hopefully, research will find a treatment that is even more efficient at repairing the permeability than curcumin etc., whilst leaving sufficient porosity to admit the few essential compounds which must be allowed through.
Thanks again
Ron
PS Viruses also open the BBB, and this week I have had a very stong head cold and sore throat. I have been much worse walking etc.
