My sister got a call yesterday around 0700. My father was on his was to the hospital.
Apparently he had fallen - there was a scrape on his arm. Additionally, he seemed very confused. So back off to the hospital he went.
The scrape in his arm, it turns out, was not the concerning matter.
The Emergency Room doctor and the nurse were the same two that had helped my dad yesterday. And they were concerned by the change in his mental state they saw over (literally) the last 24 hours. Their concern was a stroke. So he has been admitted to the hospital.
The CT scan did not reveal anything that appeared concerning. His lab work is all within normal limits - even his glucose (he is diabetic) was in normal ranges in the evening. He was scheduled for an MRI, which is not set to happen before today.
Of course, given the Plague, there is very little that we can do right now. We cannot go there. I did speak with the nurse (Who was so helpful. Everyone we have dealt with has been universally kind and helpful). He is confused, asking for me (which I suppose is a good thing as it means he still remembers I am in town). When the nurse asked for any particular helpful hints, I suggested a warm room and sports, both of which will give him some level of familiarity.
We wait. I told my sister I almost hope the MRI shows something - not that anything an MRI would show us would be a hopeful thing, but at least we would have some kind of cause - and we could formulate a plan. Now, we are just operating in the dark based on symptoms, not causes.
