Good points. 

Kind of a crap shoot it seems.

Would be nice if they figured it out. It appears it is not getting any less frequent and probably more frequent. Something ain't going in the right direction.

My oldest sister I think is 88 and she seems to be doing ok in the mind department, although has some other health issues. My other older sister which is just a year or two younger than her is suffering with loss of memory. I don't know if it has been diagnosed with an official name, but she sure has been struggling with her memory for a few years now.
