Isn't there also a phenomenon of elderly people recovering childhood memories? I've always heard of this, and relatives in their 60s and 70s have told me of vivid memories of their early life. In the same age range, they have less memory of more recent events. It's as if the transition to childhood amnesia is reversed. If some of this is true, it should provide clues for researchers to pursue.
