Canon

•
Exercise is the single most potent neuroprotective intervention — more effective than any drug or supplement
Wood: exercise increases BDNF (brain-derived neurotrophic factor) by 200-300%, promotes hippocampal neurogenesis, improves cerebrovascular function, and reduces neuroinflammation. No pharmaceutical intervention matches this combination of neuroprotective effects.

Highlights

•
Cognitive decline is not inevitable — lifestyle interventions can prevent or delay neurodegeneration by decades
Wood: the FINGER trial showed that a multi-domain lifestyle intervention (exercise, cognitive training, diet, vascular risk management) reduced cognitive decline by 25-150% in at-risk older adults over 2 years. Cognitive decline is modifiable, not predetermined.
