My maternal grandfather and my mother had Alzheimer's. About a year before my mother's passing when she lived with me, she said things like, "When I met you..." and my wife's Thai language TV had her asking about us being in China and how long would it take to get back to America. It is a heartbreaking disorder when it is your loved one, but in the POTUS it should rightfully be considered terrifying. In retirement I do things to exercise my brain in an effort to not go down that path.

I'm not a doctor but I've lived with the demented. I see what looks like it. Biden should be given a test for cognizance by a competent medical expert to put the question to rest. Actually, I think that should be a standard practice for all of our elderly politicians.

These are all over the place, except in the US press. https://youtu.be/P0AoyNdZ-RY https://youtu.be/PL3fY67ldR0

I don't mean for this to turn into a partisan political debate, but I do see what appears to me in my non-medical point of view a very disturbing and highly visible behavior on his part. I'd be equally troubled if it was a member of any political tribe.
