Low Blood Flow Predicts Alzheimer's Risk
- Low blood flow is the number one brain imaging predictor of Alzheimer's disease.
- New research suggests brain cells don't age as much as blood vessels do, shifting focus to vascular health for dementia prevention.
Reduce Vascular Harm By Limiting Stimulants
- Limit caffeine and nicotine because both constrict blood flow to the brain.
- Treat high blood pressure and heart problems seriously since higher blood pressure and heart damage reduce cerebral blood flow.
Use Food Supplements And Hyperbaric Therapy
- Increase blood flow with foods and supplements like chili peppers, beets, and Ginkgo.
- Daniel G Amen notes Ginkgo produced the 'prettiest brains' he's seen and hyperbaric oxygen therapy also raised cerebral blood flow in studies.
