UPDATE: 12:25 AM
Joy and Daniel are home now so they had a safe trip. I talked to Joy's sister Janet and brought her up to speed with the situation. All that can be done for the day is done, and we're turning in for the night. Sleep? We'll see, but it probably won't be a restful night in this family.
UPDATE: 9:03 PM
Joy called again. She's on her way home. She advises that her mother (Betty) is resting and will have an MRI in the morning. Joy has a lab test in the morning and doesn't want to miss that. We plan to go back to Raleigh next weekend to check on her.
Joy just called me and said her mother is out of danger for now and resting in the hospital. The medical staff thinks she had a seizure instead of a stroke. That's good news for the moment, but testing has to be performed to determine the cause.
