Overview

Narrative review shows social isolation and loneliness elevate dementia risk, suggesting targeted interventions in older adults.

Key Points

  • Social isolation and loneliness independently elevate dementia risk by 26% and 32%, respectively.
  • Randomized trials demonstrate targeted social interventions can slow cognitive decline and preserve independence.
  • Heterogeneity in associations underscores the need for tailored interventions considering individual contexts.
  • Routine screening for social isolation using validated tools can enhance risk-stratified intervention models.
