35 years as medical professional...
my wife has GA. Not recognized by but few doctors. She put herself on huge vitamin supplementation regimen, especially THIAMINE... I had my doubts...thought useless panic response...her MRIs looked devastating...had upper and lower ataxia, dysarthria, brain fog... She confounds neurologists with her near normal exams now.
treat yourself as if you have CD and Malabsorption Disorder... Might cost a few $$$ but she has impressed me. Lots of good GF recipies out there.
