Dad is showing memory loss - left Mom at the store, can't be allowed to drive anywhere but church ( 1 mile away) by himself, gets confused about his medications and argues with Mom or sibs if we ask him about it or make suggestions. doesn't eat much but loves sweets, forgets to eat. He's never been big on doctors saying "they just want your money" and we even have trouble getting him to go to the allergist or to get a family doctor. He's on meds for high blood pressure, COPD.
One sib insists he should see a gerontologist for a diagnosis, to see if meds might be helpful. Mom and the others don't agree. I don't know enough to say..
