Exercise Alters Brain Chemistry – May Protect Aging Synapses

/ SupremeCmdr / 9 Comments

When elderly people stay active, their brains have more of a class of proteins that enhances the connections between neurons to maintain healthy cognition.

I was about to write a snarky comment but I forgot what it was.

MIND Your Diet

/ SupremeCmdr / 2 Comments

MIND diet is associated with better cognitive functioning independently of brain pathology, suggesting that the MIND diet may contribute to cognitive resilience in older adults.

So, what is the MIND diet?

The traditional Mediterranean dietary pattern includes mainly whole, minimally processed plant foods including cereal grains, legumes, vegetables, fruit, nuts, and fish with small amounts of meat, milk, and dairy products and a regular modest amount of alcohol.4 The DASH diet emphasizes fruit, vegetables, and low-fat dairy products and includes whole grains, poultry, fish, and nuts, and is reduced in fats, red meat, sweets, and sugar-containing beverages.4 Combining the two diets, the MIND diet emphasizes natural, plant-based foods, specifically promoting an increase in the consumption of berries and green leafy vegetables, with limited intakes of animal-based and high saturated fat foods.

I became aware of the MIND diet earlier this year. It’s nice to know my dietary pattern has a name.

Internet Use in Retirement and Cognitive Function

/ SupremeCmdr / 2 Comments

Focusing on a sample of 2,105 older people from Austria, Belgium, Denmark, France, Germany, Italy, Israel, Spain, Sweden and Switzerland who have been retired since 2004, researchers examined retirees’ cognitive function in both 2013 and 2015. They specifically focused on a word recall test, where individuals were asked to recall a list of 10 words immediately, and then again five minutes later.

Results found that, on average, people who used the internet after they retired were able to recall 1.22 extra words in the recall test compared to non-internet users. However, retirees who used the internet were also more likely to be male, younger, better educated, and have been retired for a shorter period. They also appear to be in better health — even though they drink and smoke more.

Alcohol (just a wee bit) Lowers CVD Mortality Risk

Moderate alcohol intake – defined as no more than one alcoholic drink for women and two for men per day – may be associated with a lower risk of dying from cardiovascular disease when compared with individuals who abstain from drinking or partake in excessive drinking, according to a new study. Of the 53,064 participants, 7,905 (15%) experienced a major adverse cardiovascular event: 17% in the low alcohol intake group and 13% in the moderate alcohol intake group. People who reported moderate alcohol intake were found to have a 20% lower chance of having a major event compared to low alcohol intake (in adjusted analysis), and also had lower stress-related brain activity. Kenechukwu Mezue, MD, the study’s lead author, cautions that these findings should not encourage alcohol use, but that they could open doors to new therapeutics or prescribing stress-relieving activities like exercise or yoga to help minimize stress signals in the brain.

My liver understands but does not necessarily agree with the findings of this study.
