This UCLA Alzheimer's and Dementia Care video uses a home-care scenario to explain sexually inappropriate behaviour in dementia. Mr Brown has moderate dementia and has lost several caregivers after making sexual comments and grabbing during evening care. The first scene shows the situation escalating when the caregiver uses intimate language, reacts emotionally and cannot re-establish a safe boundary.

The explanation notes that sexual desire can persist despite dementia. Loneliness, boredom, disinhibition, physical closeness during personal care, bathing, dressing, continence care and body positioning can trigger sexual behaviour the person may no longer be able to censor.

The improved scene shows a calmer, more professional response. The caregiver uses Mr Brown's name, redirects his attention to family photos and warm pyjamas, asks him firmly to let go of her hand, and moves on to brushing teeth before returning to dressing.

Practical advice includes redirecting by changing the subject or using distraction, setting a calm but firm boundary, avoiding intimate pet names such as "honey" or "sweetie", keeping a safe distance if needed, and avoiding shaming. If masturbation occurs, the video suggests redirecting the person to their room for privacy. Preventive steps include using more formal clothing, mindful body positioning and, where behaviour targets a particular gender, considering whether a different caregiver match would be safer.
