Your aunt’s behavior of rubbing spaghetti sauce on her arms is likely related to her dementia. This type of unusual behavior is not uncommon in people with dementia and can be caused by various factors[1][5].
As dementia progresses, it affects different parts of the brain, leading to changes in behavior, perception, and judgment. Your aunt might be experiencing sensory issues or confusion about the purpose of the sauce[1]. She may not recognize it as food or understand how to use it properly.
Sometimes, people with dementia engage in repetitive or seemingly strange behaviors as a way of self-soothing or seeking sensory stimulation[3]. The texture or temperature of the sauce might feel comforting to her.
Another possibility is that your aunt is experiencing a symptom called “pica,” which involves eating or mouthing non-food items[10]. While spaghetti sauce is edible, using it in this unusual way could be a manifestation of pica-like behavior.
It’s important to approach this situation with patience and understanding. Try to gently redirect her attention to more appropriate activities. You might offer her a soft cloth or stress ball to handle instead, which could provide a similar sensory experience without the mess.
If this behavior persists or causes distress, it’s a good idea to consult with her doctor. They can assess if there are any underlying issues, such as skin irritation or nutritional deficiencies, that might be contributing to this behavior[5].
Remember, dementia can cause significant changes in a person’s actions and perceptions. Your aunt isn’t doing this to be difficult or cause problems. She’s likely responding to internal experiences that are hard for us to understand. Providing a safe, supportive environment and seeking professional guidance when needed are key to managing these challenging behaviors[1][3].
