Your uncle with dementia might be chewing on napkins due to a condition called pica, which can sometimes occur in people with dementia. Pica is when someone has strong urges to eat things that aren’t food, like napkins, dirt, or other inedible items[5].
This behavior can happen for a few reasons. As dementia progresses, it can affect the parts of the brain that control eating and swallowing. Your uncle might not recognize that napkins aren’t food, or he might have trouble telling the difference between what’s edible and what’s not[1].
Sometimes, people with dementia develop challenges with chewing and swallowing. They might struggle to recognize what type of food they’re eating and how to chew it properly. This could make napkins seem like a food item to your uncle[1].
Another possibility is that your uncle is experiencing changes in his sense of taste or smell. These changes can make previously enjoyable foods less appealing, and might lead to unusual cravings or behaviors around eating[2].
It’s also worth noting that some people with dementia might engage in repetitive behaviors, which could include putting things in their mouth or chewing on non-food items[1].
This behavior can be concerning because it poses a choking risk. It’s important to keep an eye on your uncle during mealtimes and try to redirect his attention if you notice him chewing on napkins or other non-food items[1].
You might want to consider serving foods that are easier to chew and swallow, cutting food into smaller pieces, or encouraging your uncle to take small sips of water between bites. These strategies can help make eating safer and more comfortable for him[1].
If you’re worried about your uncle’s behavior, it’s a good idea to talk to his doctor. They can check if there are any underlying issues causing this behavior and suggest ways to manage it safely. Remember, this isn’t uncommon in people with dementia, and there are ways to help your uncle stay safe while eating.
