Assessing Social Cognition in Older Adults: A Population-Based Study

Area of Science:

• Gerontology
• Neuropsychology
• Cognitive Science

Background:

• Mild cognitive impairment (MCI) affects a significant portion of the aging population.
• Accurate assessment of cognitive domains is crucial for early detection and intervention.
• Social cognition is increasingly recognized as a key component of overall cognitive health.

Purpose of the Study:

• To validate the assessment of social cognition in older adults within a population-based study.
• To determine if social cognition can enhance the neuropsychological classification of MCI.

Main Methods:

• A cross-sectional study of 902 adults aged 65+ was conducted.
• A social cognition composite was created using the Social Norms Questionnaire and the Reading the Mind in the Eyes Test.
• Sensitivity, specificity, and AUC were compared for social cognition against traditional cognitive domains for MCI detection (CDR=0.5).

Main Results:

• Better social cognition correlated with younger age, female sex, higher education, better general cognition, and fewer depressive symptoms.
• The diagnostic performance of social cognition for MCI was comparable to traditional cognitive domains.
• Incorporating social cognition as a sixth domain increased MCI classification by 5%.

Conclusions:

• Objective assessment of social cognition can augment cognitive evaluations in older adults.
• Social cognition is a valuable domain for identifying mild cognitive impairment.
• Integrating social cognition may improve the sensitivity of MCI detection in clinical practice.
