Repetition – People with dementia often repeat a word, question, or action over and over again (e.g., saying “What are we doing today?” repeatedly). This behavior is usually harmless, but it can be unnerving and annoying for those who are caring for the person. Repetitive behavior is usually a sign of insecurity, since people with dementia are often looking for something comfortable and familiar – something over which they have some degree of control. To address repetition, look for a specific antecedent or reason for the repetition as well as for the emotion behind it. This can reduce your chances of responding impatiently with the person. If the repetition is an action, try turning it into an activity that makes the person feel useful. For example, if the person is constantly fidgeting with his hands, try giving him some socks to sort or some knick knacks to clean.
Hallucinations – Hallucinations are sensory experiences that seem real, but are not. The most common hallucinations are visual (i.e., seeing something that is not really there) and auditory (i.e., hearing something that is not really there), but hallucinations can also occur in regard to taste, smell, and touch. Because hallucinations seem real to those with dementia, it is not helpful to try to convince the person that she is imagining things. Instead, recognize the person’s feelings, reassure the person that you are there to help, and redirect her to a pleasant activity. Also consider whether the hallucination is actually bothersome. If it is a “nice” hallucination (e.g., seeing a pretty orchard outside that is not really there), there may be no benefit in trying to discourage the behavior.
