The Cognitive Longevity Protocol — 4-Pillar Framework for Protecting Brain Function
Cognitive Longevity · 4-Pillar Protocol
The Cognitive Longevity Protocol for Adults Over 40
The 4-pillar framework that protects cognitive function into your 70s, 80s, and beyond. Citation-anchored to VITACOG, MIND diet, FINGER, and Walker research. Free PDF.
Why this matters most
If you live to 90 with intact cognition, every other longevity win compounds — you keep learning, working, relating. If you live to 90 with significant cognitive decline, the other wins matter less. Cognitive function is the keystone outcome of every longevity protocol.
Most cognitive aging risk accumulates silently in the 40s and 50s — before symptoms appear, while interventions still have maximum effect. The earlier you start running the protocol, the more it works as prevention rather than treatment.
The 4 pillars
| Pillar | Intervention | Evidence anchor |
|---|---|---|
| 1. Vascular health | apoB <60 · BP <120/80 · HbA1c <5.4% | ~60% of dementia is vascular or mixed |
| 2. Methylation | Homocysteine <7 µmol/L | VITACOG: 30% brain atrophy reduction |
| 3. Sleep architecture | 7-8 hr, 90%+ efficiency, deep sleep 15-20% | Glymphatic amyloid clearance · memory consolidation |
| 4. Cognitive reserve | Learning + social + exercise + novelty | FINGER trial: 25-30% decline reduction |
