INSIGHT

Trial Participation Drives Most Gains

  • Both the structured and self-guided groups improved in cognition over two years, with only a small additional benefit from the structured program.
  • This suggests trial participation, mindset, and social support drove most gains rather than any single specific intervention.
ADVICE

Use Multi-Domain Lifestyle Targets

  • Adopt multiple lifestyle domains: exercise, diet, cognitive activity, and social support to target cognitive health.
  • Structured programs included supervised exercise, MIND diet guidance, brain training, and group meetings as a reproducible template.
INSIGHT

Benefits Concentrate In Executive Function

  • Improvement concentrated in executive function and processing speed, not episodic memory.
  • Those with below-median baseline scores benefited most from added structure.
