My mother had a face lift at 60. She was a beautiful lady. Didn’t like the wrinkles, everything else that comes with age, so she had the face lift, and eye lid surgery. . Sorry I forgot the name of that. But for droopy eye skin. Ok. 20 years later , she looks like a Zombie. She doesn’t do well outside of the house , so I can’t take her to get her hair dyed. Some how she still cares about grey hair. I got a spray to cover grey hair. I told her, I need to spray your roots 2 to 3 times a week. Well , guess who gets a bath ? This has worked. I know she’s bathing and washing her hair. Hope this helps. I know you are talking about your husband , he may not care , about his hair the way most females do.
from my own experience: Bathing is a complex task. There are many steps involved, which can create extreme anxiety in a person with a memory or cognitive disorder. Depending upon the level of dysfunction, it may be as simple as just sitting in the bathroom for moral support and reassurance. Maybe he just needs signs with simple pictures and words for guidance. The room may need assistive devices: grab bars, transfer/shower chairs, easy access tub/shower opening. All needed items laid out, close by, in order of need. Definitive step-by-step instructions, sometimes performing actions, while maintain continual presence. Always monitor water temperature. Suggestions: Give all meds on timely basis, make sure person is not overly hungry or too stuffed from recent meal. Tend to toileting needs prior to shower or bath. relax, encourage and smile. Remember that everyone has a circadian rhythm. Perform task at peak of sustained energy.. If person is spouse, occasionally have fun. Hope this helps. Good Luck.
