Which of the following interventions has been shown to delay the onset of dementia in older adults?
Correct Answer: B
Rationale: The correct answer is B: Consistent mental and physical activity. Engaging in mental and physical activities can help improve cognitive function, increase brain plasticity, and reduce the risk of cognitive decline. Regular stimulation of the brain through activities like puzzles, reading, and learning new skills can help delay the onset of dementia. Physical activity also promotes overall brain health by improving circulation and reducing inflammation.
Choices A, C, and D are incorrect:
A: Strict dietary restrictions may have some benefits for overall health, but there is limited evidence to suggest that it directly delays the onset of dementia.
C: Regular social isolation can actually increase the risk of cognitive decline and dementia, as social interaction is important for brain health.
D: Pharmacologic interventions to control hypertension may be important for overall health, but they are not specifically shown to delay the onset of dementia in older adults.
