Experts say that mild memory loss is perfectly normal -- especially as we age. That's right, if you sometimes forget simple things, you're not necessarily developing Alzheimer's disease.There is a gang of people walking around just like you who occasionally misplace their keys, have that deer-in-headlights look as they search for their cars in parking lots, and can't recall the name of one new person they met at their last office party -- yes, the one from last night. And there's a reason for those character-themed floors coupled with the happy-go-lucky music in Disney amusement park parking garages. "If we have forgotten an appointment, we begin thinking, 'Uh oh, is this the first sign of Alzheimer's disease?' and we become much more conscious, and it gets kind of a disproportionate amount of attention when it really may be something quite benign," Stuart Zola, PhD, professor of psychiatry and behavioral sciences at the Emory School of Medicine and director of Yerkes National Primate Facility in Atlanta tells WebMD.
