WASHINGTON (AP) Alexis McKenzie's mother had mild dementia, but things sounded OK when she phoned home: Dad was with her, finishing his wife's sentences as they talked about puttering through the day and a drive to the store.

Then their phone service was cut off. "I mailed that check," McKenzie's father insisted. No, he'd mailed the phone company a bank deposit slip instead. McKenzie visited and discovered spoiling food. Dad the caregiver was in trouble, too.
