Speech and comprehension issues

[Guest guest]

Our 3yr ds had lost all words beginning of last year but started gaining words 7

months ago. The most improvement happened after HBOT though we did chelation and

Methyl B12 as well. He makes simple sentences but we do not know where to go

from here. He's had 80hrs HBOT but we are afraid of oxygen toxicity so we've

decided to stop. He's speaking gibberish sometimes, mixing it with words. He can

do this for an extended time all by himself. He still does not understand most

questions. All he can answer are simple What is this? Who is that? kind of

questions.
