A condition attributed to a generation/technology gap in elderly people based on language, body movement or driving habits; mistakenly attributed to full blown dementia or Alzheimer's disease. However, it offen closely precedes full blown dementia or Alzheimer's.
LANGUAGE: "Mom asked me if I had THE email. I think she's showing signs of Eldermentia".
BODY MOVEMENT: "See that old buzzard pulling coupon after coupon out of her pocket book in the express line? That's a classic case of Eldermentia".
DRIVING HABITS: "Did you see that Q-tip trying to parallel park? Luckily no one got hurt when he mistook the gas peddle for the brake. That's the 3rd time this week. He's way past Eldermentia and into the early stages of Alzheimer's. His kids don't want to be cut out of their inheritance, so they're not taking his keys away".
