A community health nurse is providing teaching to the family of a client who has primary dementia. Which of the following manifestations should the nurse tell the family to expect?

A. Forgetfulness gradually progressing to disorientation; Primary dementia, such as Alzheimer's disease, typically starts with mild forgetfulness (e.g., forgetting recent events or conversations) that progressively worsens. As the disease advances, clients may become disoriented to time and place, and may even fail to recognize loved ones. B. Decreased display of emotions is not a typical manifestation of primary dementia. While some individuals with dementia may show emotional instability or unpredictable emotional reactions, a decreased display of emotions is not characteristic. C. Personality traits that are opposite of original traits can occur in some forms of dementia, particularly in cases involving frontotemporal dementia. However, it is not a hallmark of primary dementia like Alzheimer's disease, where personality changes tend to be more subtle or not as extreme. D. Decreased auditory and visual acuity is not specifically associated with primary dementia. While sensory deficits can occur due to age or other conditions, dementia itself primarily affects cognitive functions such as memory, language, and executive function rather than sensory acuity.
