Hypothesis

How do social network overlaps affect older adults with and without Alzheimer's disease and their caregivers?

Conclusion

More overlap in social networks is linked to worse cognitive outcomes for individuals with Alzheimer's disease and increased loneliness for their caregivers.

Supporting Evidence

  • Family members and individuals offering psychosocial support were significantly more likely to be shared ties.
  • Instrumental support was more likely to be shared ties only in the networks of ADRD informants.
  • More network overlap was associated with worse general cognition and episodic memory among ADRD focals.
  • Higher overlap was associated with greater loneliness in ADRD informants.

Takeaway

Having the same friends and family can make it harder for people with Alzheimer's to think clearly and can make their caregivers feel lonely.

Methodology

Data from 124 dyads were analyzed using multilevel logistic regression to examine social network characteristics.
