Your aunt’s behavior of licking the backs of playing cards is likely related to a condition called pica, which can occur in people with dementia. Pica is when someone eats or mouths non-food items. In dementia patients, this might include things like paper, soap, or in your aunt’s case, playing cards.
There are a few reasons why this might be happening. As dementia progresses, it can affect the parts of the brain that control appetite and the ability to recognize what’s edible. Your aunt may not realize the cards aren’t food. She might also be experiencing changes in her sense of taste or smell, making the cards seem appealing.
Sometimes, pica behaviors in dementia patients are a way of seeking sensory stimulation. The texture or taste of the cards might be interesting or comforting to your aunt. It could also be a repetitive behavior that she finds soothing, similar to how some people might bite their nails when stressed.
In some cases, pica can be a sign of nutritional deficiencies or other health issues. It’s important to have your aunt checked by a doctor to rule out any underlying medical causes.
To help manage this behavior, try to keep the playing cards out of reach when not in use. You could offer safe alternatives for oral stimulation, like sugar-free lollipops or specially designed chewing items made for dementia patients. Keeping your aunt engaged in activities she enjoys might also help reduce the behavior.
Remember, this isn’t your aunt’s fault. It’s a symptom of her condition. Approach the situation with patience and understanding. If the behavior persists or you’re concerned, don’t hesitate to consult with her healthcare provider for more specific advice and strategies[3][5].
