Okay. The difference between Alzheimer's and other dementias and just the benign forgetfulness of old age really comes down to does the forgetfulness make a difference in your daily life? Does it affect your day-to-day living?

You may have a hard time remembering somebody’s name. You're sitting there and you're thinking, “Well, that kid that sat behind me in high school who used to always flick my ear, what was his name? I can’t think of that.” Then, sometime later, it’ll come to you. It’s frustrating but it doesn’t affect your ability to do the things you need to do day in and day out. Some of those … It’s almost like delayed … It’s delayed memory loss. It’s not really totally lost.
