Dementia affects a persons capacity to understand what is happening around them, to remember what they have just said or indeed what they have just been told. Consequently they may tell the same story more than once.

Repetitive questioning is also related to problems with remembering, but it seems to also reflect another problem in brain function. Many carers of people with dementia describe that the person they care for is most likely to ask questions repeatedly about an upcoming event. For example, knowledge that an appointment (especially a doctor’s appointment) is coming up can provoke a question to be asked many times.

Many carers find this to be an especially challenging problem. Sometimes people with dementia become upset or angry when told that they are repeating themselves and their repetition increases with stress and fatigue.
