Did you even read the headline? “Supplements won’t prevent dementia...”

The first half of the article is all about various dietary supplements and how there is no good evidence for them. But there is decent evidence for exercise, controlling blood pressure, and congnitive training.

I mention the supplements as a comparison. Like the nonsense peddled here, the techniques (increased physical activity, blood pressure management, and cognitive training) have shown preliminary promise. But all three (I boldly predict) will fail on further testing, and even now, as the article itself notes, have failed to produce results that exceed statistical significance.

This is irresponsible reporting that is falling for the exact same magical thinking that led to the hype around supplements. Because attempts to prevent dementia have been previously shown to be without merit, we should report on new ideas with a great deal of skepticism until the evidence becomes very strong.

The field of cognitive training has moved way beyond preliminary promise.

Here's a meta-analysis of 97 published randomized controlled trials, showing reliable improvements in cognitive function and transfer to real-world function [1]

Here's an NIH-funded study of more then 2,800 older adults followed for 10 years showing that speed-of-processing training reduces the risk of dementia by 29% [2]

Disclosure: I work at a cognitive training company.

A nutritionist with Ph.d with good credibility claims that he got good results with using black sesame seeds. The way he used it is - roast 2 spoons of black sesame seeds and eat once a week for 6 months (no need/should not take every day). He claims to have cured them in 6 months. If I have someone I know I would try as there is no harm in having a regular food item taken once a week. Don't know how it works or if any studies already done to back it up.
