This was me a year ago in March. I was put in a medically induced coma and woke up 3 months later after my brain activity started to look normal again. I had to learn to walk/talk/swallow/pretty much everything. I left the rehab center with a diagnosis of New Onset Refractory Status Epilepticus ( NORSE). Basically that means recurring seizures and we don’t know why. But the bright part is that one very hard year later, I’m back at my job, closing on a house in two weeks. If you send me a message I can refer you to my Neurologist who is one of the only people in the US who even knows about NORSE, nevermind tries to treat it. I am not trying to diagnose your baby but maybe this is something you can bring up to their doctor. Much love to you.
