In the following scenario, who is most correct about Marcia's condition and what she needs?

Marcia's children are discussing whether Marcia is developing dementia and how to deal with the situation. Marcia has short-term memory problems. Her judgment also seems poor at times. Marcia's daughter, Vicky, says she cannot have dementia because she can tell such vivid stories about her childhood.

Marcia's other children think she does have it. Davey feels strongly that she should be evaluated by a doctor. Beatrice says that's a bad idea; if it Alzheimer's, it is incurable, and it would only make Marcia unhappy to have a diagnosis. Chloe is also against urging Marcia to go to the doctor. She says the best treatment for early-stage dementia is good nutrition and an active lifestyle, and they don't need a diagnosis to help provide those things.
