Social isolation in older adults is associated with increased risk for which outcomes?

• A. Dementia and health issues
• B. Athletic performance
• C. Increased immune function
• D. Higher education levels

Answer: (A)

Social isolation deprives older adults of ongoing cognitive and physical stimulation, which over time can contribute to cognitive decline and an increased risk of dementia. It also tends to go hand in hand with a cluster of health problems—cardiovascular disease, hypertension, diabetes, functional decline, and higher mortality—through pathways like chronic stress, inflammation, poorer sleep, unhealthy coping behaviors, and reduced access to care. That combination makes dementia and broader health issues the most coherent and evidence-supported outcome linked to isolation in later life. The other options don’t fit as well. Athletic performance isn’t typically a direct consequence of isolation, increased immune function is not alignment with the common pattern (isolation often relates to immune dysregulation rather than heightened function), and higher education levels are not an outcome driven by social isolation.
