I suppose anybody could be, but is extreme weight loss a sign of that? She looks like she’s lost about 10 pounds since earlier this year and she was kind of skinny to begin with.
Do you know where he works? Could you give him a call at work?
I asked her two out of the three of the “stroke questions” (and ironically, she was the one who sent me the email about them). I forgot the third one, which was “have the person raise their arms.” I don’t put a lot of stock into things which go around email as medical diagnoses but for what it’s worth she could both smile and form a sentence.
When I asked her what day of the week it was and she said “Ha! They always ask you that,” and then answered the wrong day, I wondered if she was just messing with me, but that wouldn’t be typical of her, either.
She takes a lot of pills. Something for arthritis, something for bone loss, pain medication for chronic back and hip pain caused by scoliosis, antidepressants. So yeah, there’s a lot of room for pharmacological interactions there.
As another possibility…I had a teacher who did this once. She ended up having a fatal brain tumor 
Definitely keep in touch with her, and the husband. That’s not right to act that way.
Thanks to all you good folks who responded with helpful information. I’ve talked to her today (she’s much better, making a lot more sense) and I’ve talked to her husband, and she’s going to see a doctor tomorrow.
The thinking is that what’s going on is, in fact, a conflict between a drug she’s taking for arthritis and an antidepressant. But apparently it’s an odd reaction. Something she’s taking is an appetite suppressant which is why she’s lost so much weight lately, and the weight loss might have queered the dosage she originally got.
I feel a lot better knowing she’s getting checked out. Thanks again.
