Finger licking and touching things is pretty common for people with dementia. It’s not because your dad is trying to be difficult – his brain is changing, which affects his behavior in ways that might seem odd.
When someone has dementia, the parts of their brain that control impulses and social norms start to break down. So your dad might not realize that licking his fingers and touching stuff isn’t really appropriate. His sense of taste and touch could also be changing, making him want to explore things with his mouth and hands more.
Sometimes people with dementia do repetitive actions like this because it’s soothing or comforting to them. The familiar sensation might help them feel more secure when they’re confused or anxious. It could also be a way of stimulating their senses if they’re feeling bored or understimulated.
In some cases, this behavior might be linked to memories or habits from the past. Maybe your dad used to lick his fingers a lot when eating, and now that action is resurfacing even when he’s not eating.
While it can be frustrating to deal with, try to be patient. Your dad isn’t doing this on purpose to annoy anyone. Make sure he has other things to keep his hands busy, like stress balls or fidget toys. Gently redirect him if needed, but don’t scold him for the behavior.
It’s a good idea to check with his doctor too. Sometimes behaviors like this can be a sign that something else is going on, like an infection or medication side effect. The doctor might have some other tips to help manage it.
Remember, your dad is still in there, even if his behaviors are changing. Focusing on the connection you still have with him is more important than worrying about every little unusual habit. Dementia’s a tough journey, but approaching it with compassion makes a big difference.
