Melissa lives next door to her childhood home and has become the caregiver for her mother, a frail elderly woman with dementia and other physical weaknesses. which statement is not likely true of this case?

What is wrong about this sentence is that dementia is implied to be a physical problem ("dementia and other physical weaknesses").

While old age can come with many physical difficulties for individuals, the disorders gathered under the broad term "dementia" do not typically affect a person's appearance or motor functions. The areas affected have to do with cognitive abilities (thinking, problem-solving, etc.). These include memory (like Alzheimer's), feelings, language, and repetitive tasks like cooking.
