Alternative Waking Up From Coma Protocols

My niece Lizzie has been in an AVM induced coma for 3.5 weeks. She left ICU a week ago, and has been in a close observation neuro room for a week. She will be moving to an acute rehab when a room at the preferred location opens up.

My understanding is that her injury is adjacent to brain stem in the mid brain area. I think that the neurologists have been focused on the reticular activating system.

Lizzie has been receiving physical therapy as well as medication to stimulate wakefullness and sleep. I'm not exactly sure what's being prescribed beyond ritalyn and ambien.

Issue: What "wake up" protocols is the group aware of?

Chris, how is Lizzy? Has she awakened?
