A gentleman with dementia that I know explains the term "forgets", as it applies to himself. He explains that it is not that he forgets things, as that implies the thought was once there but then was gone. He says the difference for him is that the thought was never really implanted; it just passes on by. He explains this to people, to increase understanding - he does not forget things, but rather just does not have the ability to plant the thought in the first place. When caregivers know this it may help them to be patient and understanding.
