1. Replace existing clothing with garments that are difficult to remove without help, such as jumpsuits or tops with back zippers. Search online for Alzheimer’s clothing to find helpful options.

  2. Pay attention to signals. Your loved one may start to tug at a zipper or fumble with buttons when feeling uncomfortable.

  3. Keep calm. That can be a tall order when your loved one is getting naked in a restaurant. But your emotional tone can keep things on an even keel. If you shout or chastise, you risk agitating the person and facing him or her being half-naked and belligerent, too.

  4. In public, keep a shawl or extra sweater handy that you can throw around the person if you’re too late or other efforts fail.

  5. Make sure you’ve identified the right issue. Sometimes men with dementia who also have a prostate or other urological problem may be pulling down pants before reaching the bathroom simply because they have urge incontinence—an urgent need to go.
