Structured multidomain lifestyle intervention

Evidence Update
Current evidence
Structured multidomain lifestyle programmes combine diet, exercise, cognitive activity and risk management; trials used general-advice, placebo/factorial or active self-guided comparators in selected older adults. FINGER's modest cognitive-score benefit and MAPT's adjusted null comparisons support an intervention-design-specific, not universal multidomain-prevention claim. US POINTER found a small additional cognitive-score improvement from structured versus self-guided multidomain lifestyle intervention, not an intervention-versus-inactivity effect.
What changed
Structured multidomain activity can produce small cognitive-score benefits in selected settings; the evidence is not uniformly positive across designs.
What did not change
Cognitive-score improvement does not itself establish reduced dementia incidence.
Why it matters
Keeps active control, adjustment and clinical magnitude visible.
Main limitation
A nominal interval cannot override the adjusted decision threshold. Components differ; neither result by itself demonstrates dementia prevention. Both groups improved; practice effects and clinical importance require care. No demonstrated dementia-incidence reduction or component attribution.
Next proof
Identify replicable programme contrast with clinically meaningful outcomes. Longer follow-up for function, durability and dementia outcomes.
