Try three times to turn a “no” into a “yes.”
With personal care, try to create a good environment by giving a nice compliment or sharing a favorite story before you start.
Give a simple choice. Do you want to use the peppermint toothpaste or the cinnamon? This helps the person feel more in charge.
Use hand gestures to model the behavior, e.g. take the toothbrush and hold it up to your own mouth and demonstrate what you want him or her to do.
Simplify the environment whenever possible. Don’t have dozens of blouses or a bathroom sink that is cluttered. This will help you get the job done faster and provide less distraction for the person with dementia.
Sometimes you just have to give up and try again later. The person may say yes after lunch when they’ve refused beforehand.
