I suspect that it is true, It'smee, since it was sent first to my sister.At least, her report indicated that Alzheimers' patients are unable to solve the puzzle and that if you can solve it, you do not have the illness.
I feel sure, however, that it has to do with the ability to see the color and shape of the pieces rather than other things.
As long as you're worried about your mental health, I think you're
safe. We are all probably listened to carefully by our physicians for
safety about our overall health.
