I’m happy to share the news of yet another research study showing benefits from using BrainHQ—this one on people with heart failure. Cognitive impairment is common among people with heart failure, which can impede self-care and impact health outcomes. In the study, researchers compared three groups: a stretching and flexibility group, a walking group, and a “combined training” (walking plus BrainHQ) group. The results showed clinically significant benefits from the combined training group, but not from the other two. Learn more in this article from Health News Digest.

Putting It All Together

To recognize objects, our brains dissect visual items into different properties—texture, color, and so on—then put them back together to determine what something is. That’s how we know both chihuahuas and Great Danes are dogs, and pillows, cars, and cows are not. In an interesting study, scientists in Germany have now discovered that just 49 properties enable us to identify almost every object. These include “fluffy,” “circular,” “colorful,” and more. Find out more.

Bacteria and the Brain

Did you know that in one sense, people are more bacterial than human? Bacterial cells actually outnumber human cells in the body—and 100 trillion bacteria live in your gut. More and more evidence suggests that these gut bacteria affect how the brain works. Now, scientists are hard at work figuring out whether we can change our gut microbiome to improve mood, thinking, and behavior. Learn more.

Socializing for Gray Matter

Research has previously shown that a rich social life can have cognitive benefits, but a new study takes it a step further. The study used a sensitive brain imaging tool to show that socially engaged older adults tend to have more robust gray matter in areas of the brain related to dementia. Does this mean that doctors should start to “prescribe” socialization to preserve brain health? Find out.

The Cognitive Costs of COVID

A new study (not yet peer-reviewed) on 84,000 people found that there can be severe cognitive consequences from a COVID-19 infection, even after other symptoms are gone. In the study, researchers from Imperial College London found that some people experienced cognitive decline similar to 10 years of aging. Find out more.

Stay Positive

A long-term study that followed people for several years has found that “positive affect”—feeling upbeat and cheerful—is associated with less memory decline with age. Just another good reason to try to stay positive and maintain a zest for life! Learn more.
