I happen to work (director, corporate communication) for a specialized healthcare company that specializes in the treatment of traumatic brain injury.
Brain injury is very odd - your brain doesn’t “regenerate” or “heal” in the sense that other organs do. It’s quite literally just gray matter, and once the damage is done, the “healing” comes from the person actually having to “relearn.” It can be a long hard road, but the outcome can often be really impressive, depending on the severity of the injury.
I would highly recommend someone pass this along to Miss D’s brother … make sure, once she’s medically stable, that she is sent to a post-acute treatment facility that specializes in TBI. I will be happy to speak directly to her brother/family, and of course must recommend our facility here in Arkansas, as the outcome is spectacular.
Also, hippotherapy will probably be the key to Miss D’s recovery, when she wakes up. Make sure you push for that! Horses are healers - we all know that!
Best to you,
Robby
