A nurse is caring for a client who is experiencing fluctuating cognition and visual hallucinations. Which of the following types of dementia should the nurse expect this client to have?

A. Prion disease (e.g., Creutzfeldt-Jakob disease) is a rapidly progressive and fatal neurodegenerative disorder. It typically presents with rapid cognitive decline, myoclonus, and motor dysfunction, rather than the fluctuating cognition and visual hallucinations characteristic of Lewy body dementia. B. Traumatic brain injury (TBI) can lead to cognitive impairment or dementia later in life, but the hallmark symptoms of TBI-related cognitive decline are generally memory deficits, attention problems, and executive dysfunction, without the typical visual hallucinations and cognitive fluctuations seen in Lewy body disease. C. Lewy body disease (or dementia with Lewy bodies) is characterized by fluctuating cognition, recurrent visual hallucinations, Parkinsonism (movement symptoms), and REM sleep behavior disorder. The cognitive fluctuations and vivid visual hallucinations are distinguishing features that help differentiate it from Alzheimer’s dementia or other types of dementia. D. HIV infection can cause HIV-associated neurocognitive disorder (HAND), presenting with gradual cognitive decline, attention deficits, and motor slowing, but visual hallucinations and fluctuating cognition are less typical.
