Why is my uncle with dementia putting toothpaste in his hair?

Your uncle’s behavior of putting toothpaste in his hair is likely a symptom of his dementia. This kind of unusual action is not uncommon in people with dementia and can be caused by a few different factors.

As dementia progresses, it affects a person’s memory, thinking, and behavior[1]. Your uncle might be confused about the purpose of toothpaste or may have forgotten how to use it properly. He could be mistaking it for hair gel or shampoo.

Sometimes, people with dementia develop a condition called pica, where they have cravings to eat or use non-food items in strange ways[9]. This can happen when they’re feeling stressed or upset.

Dementia can also cause problems with recognizing objects (called agnosia) and difficulties performing familiar tasks (called apraxia)[1]. Your uncle might not recognize the toothpaste tube or remember how to brush his teeth.

It’s also possible that your uncle is experiencing some sensory issues. Dementia can change how a person perceives their environment, and the cool, smooth texture of toothpaste might feel soothing to him[1].

This behavior could also be a form of self-expression or a way of seeking attention. As dementia progresses, communication becomes more difficult, and some people might resort to unusual actions to express themselves or get help[1].

It’s important to approach this situation with patience and understanding. Try to figure out if there’s an underlying need your uncle is trying to meet. Maybe he wants to groom himself but is confused about how to do it. You could try guiding him through his grooming routine or providing safer alternatives that mimic the sensation he’s seeking.

Remember, this behavior isn’t intentional. Your uncle isn’t trying to cause trouble – his brain is changing, and he’s doing his best to make sense of his world. If this behavior continues or you’re concerned, it’s a good idea to talk to his doctor. They might be able to suggest strategies to help or check if there are any other health issues contributing to this behavior.

Caring for someone with dementia can be challenging, but with patience and the right support, you can help your uncle navigate this difficult time.
