: Resveratrol and Cognitive Decline: a Clinician Perspective

Article summary: Resveratrol and Cognitive Decline: a Clinician Perspective

This article, published in the journal Archives of Medical Science in 2019, reviews research on resveratrol in brain degeneration and cognitive decline such as dementia and Alzheimer's disease.

What is Resveratrol?

Resveratrol is a substance in the polyphenol group (polyphenol) type stilbene found in abundance in

Red grapes and mulberries

Has outstanding features

Antioxidants (Antioxidant)

anti-inflammatory (Anti-inflammatory)

Protect nerve cells (Neuroprotection)

Mechanisms that help slow down dementia

1. Reduce oxidative stress (Oxidative Stress)

Resveratrol helps eliminate free radicals. Reduce brain cell damage and increases the body's natural defense enzymes, such as glutathione peroxidase.

2. Reduce inflammation of the brain

Helps reduce NF-κB activation and reduce the production of inflammatory substances such as

TNF-α

Nitric oxide (NO)

COX-2

Cytokines

which is related to Alzheimer's disease

3. Reduce the accumulation of Amyloid-beta (Aβ).

Aβ is a protein that accumulates abnormally in Alzheimer's patients.

Resveratrol helps

Reduce Aβ production

Increases Aβ elimination

Reduces the toxic effect of Aβ on brain cells.

Including affecting the levels of Aβ40 in the blood and cerebrospinal fluid.

4. Stimulate Sirtuins and Cell Survival

It is involved in slowing cell aging, DNA repair, and nerve cell survival. Makes the brain more resistant to deterioration

Evidence in humans

Randomized clinical trials have found that Resveratrol helps.

Increase blood flow to the brain

Increases the expansion of cerebral blood vessels

Helps improve memory test scores.

Increase the feeling of thinking better (perceived performance)

For example, resveratrol doses of 75–300 mg have been shown to increase cerebral vasodilator responsiveness. And in women who were 14 weeks postmenopausal, it was associated with better cognitive function scores.

Author's main conclusions

Long-term use of Resveratrol at appropriate dosages and has improved absorption It has a significant protective effect against dementia in humans.

Brief summary

“Resveratrol is not a cure for Alzheimer's. But it is a natural substance with high potential to slow down dementia.”

especially through

Reduce inflammation

Reduce free radicals

Reduce Amyloid-beta

Increase blood supply to the brain

Therefore, it is very suitable for the Preventive Medicine + Healthy Aging approach.
