Visual Hallucinations and Paranoid Delusions.

Visual well-formed hallucinations, fluctuations in the level of cognition, and alertness and extrapyramidal signs are core features of dementia with Lewy bodies. Some patients realize that what they are seeing or hearing are just hallucinations and learn to accept them. Others, however experience these hallucinations as quite real and cannot be dissuaded from the firm belief that they are. In fact, efforts to dissuade them often serve only to confirm the often associated paranoid delusions and this may lead to a catastrophic ending. Hence, it is best not to contradict the patient. Instead, attempts should be made to distract the patient and change the focus of her or his attention. In this case scenario, we present a 68-year-old man who has been diagnosed with dementia with Lewy bodies. He lives with his daughter. He has visual hallucinations and paranoid delusions that worsen at night: He thinks there are people outside the house plotting to kill him. We discuss what went wrong in the patient/caregiver interaction and how the catastrophic ending could have been avoided or averted.

Impulsive, Disinhibited Behavior-Dining in a Restaurant.

Dining in a restaurant with a loved one who has dementia can be an ordeal, especially if the expectations of the caregiver do not match those of the patient and the restaurant environment is not suitable for patients with dementia. The size of the dining area, lighting, background music or noise, décor of the room, number of customers, variety of the items on the menu, number of plates and cutlery on the table, in addition to flowers, candles, and other decorations on the table are all potent distractors. There are so many stimuli; the patient can be overwhelmed with information overload and not able to focus on the main purpose of the event: have dinner and especially enjoy the other person's company. In this case scenario, we present a 62-year-old man diagnosed with behavioral variant frontotemporal dementia (bvFTD). His daughter "invited" him to have dinner with her at a very fancy restaurant to celebrate her promotion at work. Unfortunately, whereas the evening started very well, it had a catastrophic ending. We discuss what went wrong in the patient/daughter interaction and how the catastrophic ending could have been avoided or averted.
