Similar to Kitchenheimer's, a portmanteau of 'stairs' and 'Alzheimer's'. Forgetfulness that occurs due to going up or down stairs. The two most common types are:

1. Directional Stairsheimer's. This is when you can't remember if you just walked down the stairs or if you were about to go up.
2. Situational Stairsheimer's. This is when you come down the stairs to get or do something, but forget what that thing is as soon as you get to the bottom. Then you go back up the stairs and immediately remember what it is.
Husband: Why are you going up and down the stairs?
Wife: My Stairsheimer's is acting up. I'm trying to remember what I walked downstairs to do.
