So your mom's scans didn't show anything either...? I just wish we knew what was going on. She seems perfectly normal to us except for these constant slips of memory, which as I said, we suddenly started to notice about a year and a half ago. She also has occasional major anxiety attacks, but usually she's just fine. I sure hope it turns out to be something... treatable.
I wish you the best with your mom. I hope everything goes well.
