First of all, I really feel for you for what you are going through right now and you can only do what you are capable of doing.. Same with me when I was sick with lyme, I took baby steps as that is all I could handle. Some days I couldn't handle anything.
Anyway, I think Dr. Jernigan could have used a better term instead of "Leaky" as in reality, nothing is leaking from our brains. I think all he is basically saying is to detox and that some people suffer from brain fog and other symptoms and what can be done about it. But the key word I get from his article is to detox. It's not as dramatic as he is making it sound.
I hope you feel better and please only do what you feel you can handle as that's the best way!
