A nurse is caring for a client who has dementia. Which of the following findings should the nurse expect?

A. Acute onset of confusion. Dementia is a progressive, chronic condition that develops gradually over time. An acute onset of confusion is more characteristic of delirium, which is a sudden, reversible condition often caused by infections, metabolic imbalances, or medications. B. Illusions. While individuals with dementia may experience visual misperceptions, true illusions—misinterpretations of real external stimuli—are more commonly associated with delirium or psychiatric disorders. Dementia more often leads to problems with recognition (agnosia) rather than distorted perception. C. Memory loss that disrupts ADLs. Dementia is characterized by progressive cognitive decline, including memory impairment severe enough to interfere with daily activities such as managing finances, preparing meals, or personal hygiene. As the disease progresses, individuals may struggle with problem-solving, language, and recognizing familiar people or places. D. Catatonia. Catatonia is a state of motor dysfunction, often seen in severe psychiatric disorders like schizophrenia. While individuals with advanced dementia may become withdrawn or exhibit reduced movement, true catatonia, which involves stupor or repetitive movements, is not a hallmark of dementia.
