She hasn't regained consciousness. That may be partly because of the (anti-seizure) sedation, but her doctor says that people who keep seizing for more than 24 hours usually have a bad outcome.
She also had staph infection in her blood, so they're giving her antibiotics, and they are (still?) keeping her blood pressure up with drugs.
I'm not optimistic -- though if anyone can beat the odds, it's Marsha.
