Even if a patient with Alzheimer's has healthy eyes, the brain can distort what the patient sees. Depth perception changes, too, as does the ability to recognize common items. For an 81-year-old man whose mind tells him he's now in his teens or younger, seeing his reflection in a mirror can be alarming.

If your loved one wouldn't understand or know what to do if the police called your home because you'd been in an accident, you need to wear a medical ID bracelet. With the right info, it alerts first responders that your spouse has dementia.

More than 20 years ago, my husband successfully thru-hiked the Appalachian Trail. More recently, he took a walk in our small condo complex. When he was finished, he got frustrated because his key wouldn't unlock the front door. It wasn't our front door.

The power of a name is not restricted to fairy tales. For the longest time, I couldn't bring myself to talk about my husband's diagnosis: Alzheimer's. When I finally faced the power loaded in that word, everything changed.

There was a difference between the news I expected and the news we received. Hearing "Alzheimer's," our future suddenly crumbled. The disease affects everyone differently. Maybe my husband wouldn't forget who I was. Maybe he wouldn't forget where we lived. Maybe he wouldn't get any worse than he was now. Maybe pigs fly.

I had so much to learn.
