Alzheimer's? Light a Path to the Bath at Night

If your parent's Alzheimer's makes it hard for her to remember where the bathroom is in the middle of the night, put down reflective tape along the floor and install motion-activated nightlights that plug into a hall socket and light up only as you walk past (about $15 at hardware stores). This creates a path to the bathroom that's easy to see at night while remaining unobtrusive by day.
