This is horrible. Who knows what she is feeling, thinking or experiencing, but to her it's very very real.

It really sounds like she injured her brain in the car accident. Traumatic brain injury causes a very wide range of problems.

The psychiatric meds may help get her stabilised but it is not a fix, she needs to fix her brain.

The only treatment currently that I'm aware of that promotes brain repair after TBI is low pressure hyperbaric oxygen therapy. However, its unfortunately not yet generally accepted. There's currently a phase 3 HBOT TBI clinical trial going on in the USA, which means that there is a lot of evidence already and it is hopefully close to being added as an approved indication for HBOT:

Stem Cell treatments are currently being trialled, and I remember reading some early studies that show their effectiveness, however this is probably 10 years away from even early adoption by the medical profession.

Here are some papers regarding the effectiveness of HBOT for TBI:

The DOD studies showed similar results at the correct pressure, however the authors came to the wrong conclusions. Apparently it was a hatchet job so they don't have to pay for HBOT for all the veterans returning with TBI. Strange considering the liftetime costs of TBI disability are so high:

If you can get her stabilised and out of the institution I would highly recommend getting her to New Orleans to see Dr Harch for HBOT. He saved my life that's for sure. There are other HBOT clinics around, though Dr Harch is the leading author and advocate for this therapy and has been for some time.

However, I think the biggest battle here is going to be legal and I'm really unable to help you here.
