Pay attention to your parents’ appearance. Failure to keep up with daily routines — such as bathing and tooth brushing — could indicate dementia, depression or physical impairments.
Also pay attention to your parents’ home. Are the lights working? Is the heat on? Is the yard overgrown? Any changes in the way your parents do things around the house could provide clues to their health. For example, scorched pots could mean your parents are forgetting about food cooking on the stove. Neglected housework could be a sign of depression, dementia or other concerns.
