Check out the Gabapention (I believe it is the generic for Neurotin)
and it can cause extreme drowsiness. My husband
and my aunt were on it for some time
and I saw changes in both their personalities. I, too, forget what I go into another room for and have been doing that for years. I am 66. I have heard dementia described as, not forgetting where you parked your car, but forgetting that you HAVE a car. That said, it wouldn't hurt to get it checked out.
