Key Questions

How does optimism affect dementia risk?

A study (n=9,071 over 14 years) shows optimism reduces dementia risk (HR 0.85), highlighting its protective role.

Can brain training delay dementia onset?

Cognitive training like ACTIVE (n=2,832, 25% risk reduction) and Swedish hobbies (-7% per hour) may lower dementia risk up to 20 years later.

What lifestyle factors like exercise and strength training delay Alzheimer's?

A compact package of aerobic/resistance/Zone2/HIIT (~5k steps), grip strength (-26% risk), and Dr. Wood's 3S approach promote brain plasticity and declining incidence.

Are vitamins like D and omega-3 linked to lower Alzheimer's biomarkers?

Vitamin D associates with lower tau levels (n=793), and omega-3/B vitamins/sleep/Med/VOO show tau drops, supporting delay strategies.

Why review medications for dementia prevention?

Deprescribing certain popular medications (e.g., 7 noted for seniors) causing memory loss, alongside oral hygiene and avoiding screens, aids onset delay.
