Episode notes
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.
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.
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.
