Your father’s behavior of trying to erase imaginary writing on the walls is a common symptom experienced by some people with dementia. This type of behavior is often referred to as a hallucination or a delusion.
In dementia, the brain undergoes changes that can affect perception and thought processes. Your father might genuinely believe he sees writing on the walls, even though it’s not actually there. His attempts to erase it are his way of responding to what he perceives as real.
This behavior could be triggered by various factors. Sometimes, shadows or patterns on the wall might be misinterpreted as writing. In other cases, it might be related to memories or past experiences that have become mixed up with the present in your father’s mind.
It’s important to understand that for your father, these hallucinations feel very real. Trying to convince him that there’s no writing on the wall might lead to frustration or distress. Instead, it’s often more helpful to acknowledge his experience without reinforcing the delusion. You could say something like, “I see you’re concerned about the wall. Let’s look at it together.”
If this behavior is new or suddenly more frequent, it’s a good idea to consult with your father’s doctor. Sometimes, hallucinations can be a side effect of medication or could indicate an underlying health issue that needs attention.
Remember, this behavior isn’t something your father can control. It’s a symptom of his condition, not a choice he’s making. Approaching the situation with patience and understanding can help both you and your father navigate this challenging aspect of dementia[1][3].
