Understanding Cognitive Aging

Further research on how we age.

Last week, we had a post on How Old Do YOU feel? “The study considered 92 diseases and conditions in 195 countries and territories.”

Let’s continue with that topic. In new research by Lee Ryan, et al., the authors discussed “Applying Precision Medicine to the Field of Cognitive Aging” in Frontiers in Aging Neuroscience:

“The current ‘one size fits all’ approach to our cognitive aging population is not adequate to close the gap between cognitive health span and lifespan. In this review article, we present a novel model for understanding, preventing, and treating age-related cognitive impairment (ARCI) based on concepts borrowed from precision medicine. We will discuss how multiple risk factors can be classified into risk categories because of their interrelatedness in real life, the genetic variants that increase sensitivity to, or ameliorate, risk for ARCI, and the brain drivers or common mechanisms mediating brain aging. Rather than providing a definitive model of risk for ARCI and cognitive decline, the Precision Aging model is meant as a starting point to guide future research. To that end, after briefly discussing key risk categories, genetic risks, and brain drivers, we conclude with a discussion of steps that must be taken to move the field forward.”

National Health and Nutrition Examination Survey

How healthy are Americans?

How healthy are those living in the United States? We know that our rank worldwide is not great. But, we must further measure our health to learn more. Hence, the National Health and Nutrition Examination Survey. It is conducted by the National Center for Health Statistics (NCHS, which) is part of the Centers for Disease Control and Prevention (CDC).

First, look at these relevant posts:

How Old Do YOU feel?

To answer, think about the new age 65.

For me, this is really a two-part question. At age 70, I feel great both psychologically and mentally. I perceive myself as much younger than I am. On the other, how I feel physically is another story. The key for me is not to let my physical ailments overpower my psychological wellbeing. So, how old do YOU feel?

With the above in mind, consider the highlights of a very interesting article by Robert Roy Britt for Medium:

“By 2050, the percentage of the elderly is expected to double globally compared to today. As people live longer and an ever-higher percentage of the population is beyond their retirement years. This according to the World Health Organization. Meanwhile, conventional measures of longevity don’t reflect the quality of extended time on this Earth.”

“A new study looked at aging, health, and mortality by analyzing at what age people in a country actually feel like 65-year-olds, as defined by experiencing the health problems of the average 65-year old globally. The study considered 92 diseases and conditions in 195 countries and territories. The results are a window into both longevity and health status, revealing how well people age, or how poorly, the researchers report  in the journal Lancet Public Health.”

“The findings ‘show that increased life expectancy at older ages can either be an opportunity or a threat to the overall welfare of populations, depending on the aging-related health problems the population experiences regardless of chronological age.’ said Dr. Angela Y. Chang, lead author of the study from the Center for Health Trends and Forecasts at the University of Washington.”

In this study, the United States did not fare so well. For the top 10 countries cited in the chart below, people were all in their mid-70s before feeling 65. The U.S. ranked 54 at 68.5. Certainly, that is food for thought.

Medicinal Plants as a Cancer-Fighting Tool

Bring Asian research insights to the rest of the world.

Did you know? Certain plants may help us fight cancer. Read on!!

According a report by the National University of Singapore:

“Researchers found the effects in leaves of the bandicoot berry (Leea indica), South African leaf (Vernonia amygdalina), and simpleleaf chastetree (Vitex trifolia). Three other medicinal plants also demonstrated anti-cancer properties. ‘Medicinal plants have been used for the treatment of diverse ailments since ancient times, but their anti-cancer properties have not been well studied,’ says Koh Hwee Ling, associate professor from the National University of Singapore’s pharmacy department. ‘Our findings provide new scientific evidence for the use of traditional herbs for cancer treatment, and pave the way for the development of new therapeutic agents.’ The findings, which appear in the Journal of Ethnopharmacology, highlight the importance of conserving these indigenous plants as resources for drug discovery and understanding these natural resources.”

“The experiments involved preparing extracts of fresh, healthy and mature leaves of the seven plants, and testing the extracts with the cell lines of seven different types of cancers—breast, cervical, colon, leukemia, liver, ovarian, and uterine. The team opted to examine leaves as they can regrow without harming the plants—making it a sustainable choice, unlike using the bark or roots.

Happy Father’s Day — Be Well!

We love you dads!

Father’s Day is a special time for many of us. I lost my father Joseph and father-in-law Murray quite a while ago. But this is when I think of them the most. It is also special for me because I always get to celebrate with my wife Linda and daughters Jennifer and Stacey, and their spouses Phil and Adam. 🙂 🙂 🙂 🙂

My wish on this day is for all of us, including you dear readers, to be as well as you can for as long you can.

And remember …..

Happy Father's Day -- Be Well!

Happy Father’s Day — Be Well!

Did you know that this past week was National Men’s Health Week? As the Centers for Disease Control and Prevention notes:

“National Men’s Health Week is observed each year leading up to Father’s Day. This week is a reminder for men to take steps to be healthier. But they don’t have to do it alone! Whether it’s your husband, partner, dad, brother, son, or friend you can help support the health and safety of the men in your life.”

Here’s how:

“You can support the men in your life by having healthy habits yourself and by making healthy choices. Eat healthy and include a variety of fruits and vegetables every day. Regular physical activity has many benefits. It can help control your weight, reduce your risk of heart disease and some cancers, and can improve your mental health and mood. Find fun ways to be active together. Set an example by choosing not to smoke and encourage the men in your life to quit smoking.  Help the men in your life recognize and reduce stress. Learn ways to manage stress including finding support, eating healthy, exercising regularly, and avoiding drugs and alcohol.”

“Encourage men to see a doctor or health professional for regular checkups and to learn about their family health history. Every 40 seconds someone in the U.S. has a heart attack. Know the signs of a heart attack and if you think you or someone you know is having a heart attack call 911 immediately.”

Depression is one of the leading causes of disease or injury worldwide for both men and women. Learn to recognize the signs and how to help the men in your life. Signs of depression include persistent sadness, grumpiness, feelings of hopelessness, tiredness and decreased energy, and thoughts of suicide.”

Happy Father's Day -- Be Well!

 

Be Careful with Supplements

Choose your supplements wisely.

As part of our daily regimens, some of us take dietary supplements. BUT, we must be careful with these supplements.

In a very detailed and informative article, Markham Heid reports on issues related to supplement misuse. After just a short time, this article has received more than 11,100 likes!!!

According to Heid:

Background

“Earlier this year, federal authorities announced plans to strengthen oversight of the supplement industry. ‘The growth in the number of adulterated and misbranded products — including those spiked with drug ingredients not declared on their labels, misleading claims, and other risks — creates new potential dangers,’ said U.S. Food and Drug Administration (FDA) commissioner Dr. Scott Gottlieb in a February press release.”

“Heightened oversight is needed, Gottlieb argued, because expansion and change within the supplement industry has made it difficult for his agency to keep pace. ‘What was once a $4 billion industry comprised of about 4,000 unique products, is now an industry worth more than $40 billion, with more than 50,000 — and possibly as many as 80,000 or even more — different products available to consumers,” he said.”

BE CAREFUL!!!

“From multivitamins and botanicals to probiotics and protein powders, roughly three out of four Americans now take some kind of supplement on a regular basis. Since the days of palliative tonics and snake-oil salesmen, Americans have been readily lured by the promise of health or longevity in the form of a drink, pill, or powder. While the terminology has evolved — ’biohacking’ and ‘nutraceuticals’ are some of the buzzwords du jour — the implied benefits of most supplements still outpace or ignore the science. And despite recent studies that find supplements are frequently contaminated or that the best way to get nutrients is through food, Americans’ interest in supplements is only growing. And experts say many supplement users don’t recognize or appreciate the risks that accompany the use of these products.”

“The lesson here isn’t that supplements give people cancer. Rather, it’s that approaching supplements as though they’re all upside is a misguided and potentially harmful operating philosophy. When you swallow a capsule packed with concentrated amounts of a vitamin, nutrient, or other substance — a practice that did not become widespread until very recently — you can get into trouble.”
