FROM THE BRAINFLOW BOOK
Evidence-based articles drawn from our research and the BrainFlow book.
Every cognitive function depends on the brain receiving adequate blood flow. When cerebral circulation is compromised, even modestly, the effects ripple across every domain of mental performance.
Transcranial Doppler studies reveal that cerebrovascular reserve — the brain's capacity to increase blood flow — is a leading biomarker of cognitive aging. Here is what you can do about it.
From chronic sleep deprivation to a sedentary lifestyle, these modifiable risk factors directly accelerate brain vascular aging — and all of them can be addressed with targeted interventions.
No pharmacological intervention has yet matched the impact of regular aerobic exercise on cerebrovascular health. A 12-week program can reduce brain age by an average of 5.2 years.
Fewer than 6 hours of sleep per night reduces cerebrovascular reactivity by 23%. This is not a rounding error — it is a clinically significant impairment with measurable cognitive consequences.
A Mediterranean-style dietary pattern reduces brain vascular aging by an average of 4.1 years over six months. Here is the mechanism — and how to implement it practically.
