Hi Phil, I am sorry you are having the cognitive issues. I know how scary it is to feel like you are losing your mind. During my worst time, it was pretty bad for me. I still have some word retrieval issues at times and names are very hard, but as far as the rest, it isn't so bad anymore. I hope that what you have settles down and you get past the brain fog.
Please keep us updated and reach out if you need help.
Also, would you mind telling us what tests your dr. runs for toxins? It's always good to see how creative each others doctors are when trying to figure this out and compare notes.
