Once a general MD gave dad (who had dementia) the wrong meds which CLEARLY said on his chart, DO NOT GIVE...anyway, daddy laid on his back and rode an imaginary bicycle for two days straight. I kid you not. I was worn out watching him. He would wear out, take a fifteen minute nap, then up came the legs and she would begin traveling once again. There is no telling how many miles he made in that two day period.

Meds CAN affect the elderly and especially when they have dementia of any kind.
