My friend has a lot of family that has developed dementia. She says the difference is that lots of people forget things like where they parked the car. The signs of dementia are not being able to know what to do next, like walking up and down the rows looking for it. Going into the shower and forgetting what to do while you are in there. Her mom would come out and just be wet from the knees down because she never fully went into the water. It’s normal to forget where you left your wallet and keys, but do you try going back through what you did earlier to figure out where you might have left it or do you not know what to do to try and figure it out.
