Hello @humphrey, Welcome to Connect. I know it must be terribly concerning to have your husband diagnosed with such a rare condition as glial fibrillary acidic protein astrocytopathy (GFAP). @gardrums123 and @hassel may be able to share some thoughts or suggestions with you. You also might find the article listed earlier in the discussion helpful for learning a little more about the condition.
