2. How to comfort a person with dementia in case of repetitive behaviours?

Let’s look at this example

John is taking care of his father Joe, because his mother, the main carer, is out of the house for a few hours. All seems fine, although John notices that his father is rather tense because John’s mother is not there.

John and Joe eat lunch together. Sometime after finishing lunch, Joe asks “When is lunch?” and, “What are we having for lunch?” John does not think much of it at first. Then, again, a few minutes later, Joe asks “When is lunch?”, “What are we having for lunch?”, and “Where is your mother?” Joe repeats these questions again and again.

John is confused about why Joe is doing this and gets more  and more worried about his father. John continues to answer the questions, but gets a bit upset and raises his voice. John responds, loudly and is annoyed, “I have already answered these questions, why do you keep asking?”
