Ok, So Does Weight Cause Cognitive Deficits?

Here‘s another article about predictors of cognitive deficits. Seems more weight is linked to poorer mental acumen. The headline is better than most, in that it doesn’t plead causality, but it still doesn’t clarify theory underlying the phenomenon, although some suggestions come up, and the author mentions a couple covariates that didn’t seem to explain what’s going on. Interesting stuff!

In general, the researchers found, people with a high body mass index (BMI) garnered lower test scores than those with a lower BMI. They also tended to show greater cognitive decline between the two test periods.

Factors such as age, education and general health did not seem to explain the link.
