Dementia can cause changes in eating habits and behaviors, including trying to eat non-food items. This is called “pica” and is common in people with dementia. There are a few reasons why this might happen:
Brain changes from dementia can affect a person’s ability to recognize food. They may mistake other objects for food or not understand what is safe to eat.
Dementia often alters taste and smell, which can make familiar foods seem strange or unappetizing. This may lead to seeking out other items to eat.
Some people with dementia experience increased appetite or constant hunger, causing them to try eating anything within reach.
Certain medications can also increase appetite or cause confusion about what is edible.
Nutritional deficiencies sometimes contribute to pica behaviors in dementia patients.
Boredom or anxiety may lead to fidgeting and putting objects in the mouth.
To help manage this behavior:
Remove non-food items from easy reach
Provide safe objects to handle and chew on
Offer frequent healthy snacks and drinks
Use colorful plates to make food more visually appealing
Maintain a consistent mealtime routine
Consult their doctor about possible underlying issues
While concerning, this behavior is not uncommon in dementia. With some adjustments, you can help keep your uncle safe while meeting his needs[1][2][3].
