Alzheimer disease involves deterioration of which of the following?

• A. Visual acuity and perception
• B. Auditory processing and hearing
• C. Motor coordination and balance
• D. Memory and cognitive functioning

Answer: (D)

Verified step by step guidance

1. Understand that Alzheimer's disease primarily affects brain functions related to memory and cognition rather than sensory or motor systems.
2. Recall that Alzheimer's disease is characterized by the progressive deterioration of neurons in areas of the brain responsible for memory formation and higher cognitive processes, such as the hippocampus and cerebral cortex.
3. Recognize that visual acuity, auditory processing, and motor coordination are generally not the primary domains affected in the early or main stages of Alzheimer's disease.
4. Identify that the hallmark symptoms of Alzheimer's include memory loss, difficulty with problem-solving, confusion, and impaired judgment, all of which relate to cognitive functioning.
5. Conclude that the correct answer focuses on the decline in memory and cognitive abilities, which aligns with the known pathology of Alzheimer's disease.
