Social isolation and cognitive function in Appalachian older adults

Area of Science:

• Gerontology
• Neuroscience
• Social Psychology

Background:

• Social isolation is a growing concern among older adults.
• Understanding its impact on cognitive function is crucial for public health.
• Existing research suggests a link, but specific cognitive domains require further investigation.

Purpose of the Study:

• To investigate the relationship between social isolation and cognitive function in older adults.
• To identify specific components of social isolation that impact cognitive abilities.
• To inform the development of targeted cognitive interventions.

Main Methods:

• A cohort of 267 Appalachian older adults (aged 70-94) participated.
• Cognitive function was assessed using a neuropsychological battery.
• Social isolation, disconnectedness, and perceived isolation were measured using the Lubben Social Network scale-6.

Main Results:

• Significant positive associations were found between social isolation measures and cognitive function across multiple domains.
• Perceived isolation explained more variance in overall cognitive functioning (10.2%) than social disconnectedness (5.7%).
• Poorer cognitive function was observed in individuals reporting higher levels of social isolation.

Conclusions:

• Social isolation is significantly associated with poorer overall cognitive functioning in older adults.
• This association extends to specific cognitive domains including memory, executive functioning, attention, and language.
• Findings underscore the importance of addressing social isolation in interventions aimed at preserving cognitive health in aging populations.
