My nephew was transferred from Vermont to Mass General late Wednesday night. After extensive testing that lasted all day yesterday, they've finally arrived at a diagnosis. Thankfully, they were able to make the diagnosis without having the perform the double brain biopsy which they'd been planning.
My nephew's undergoing heavy immuno-suppressant therapy to combat the symptoms, but at least his condition is not fatal. The extent of his recovery remains to be seen.
Thank you for your prayers and good wishes.
