Activity and Breast Cancer Survival

Leave a reply

pinkribbon.jpgWhile it might seem odd to write about breast cancer on a site dedicated to brain health, there are two compelling reasons to do so: First, many of us have a loved one who has been diagnosed with breast cancer and second, activity is one of the major components of the brain health lifestyle.
A recent study conducted at the Yale School of Medicine indicates women who stay active after being diagnosed with breast cancer have a better chance of surviving the disease. This includes those who take up exercise for the first time after diagnosis and even if the women just do a little exercise. This study reinforces many other studies that link exercise to reduction in risk of breast cancer.
Women who got the equivalent of two to three hours of brisk walking each week in the year before they were diagnosed with breast cancer were 31 percent less likely to die of the disease than women who were sedentary before the diagnosis. Further, two years after diagnosis, women who did any recreational activities at all had nearly 65% lower risk of dying then women who were inactive at that point. Women who got at least two hours of brisk walking in weekly reduced their risk of death by 67%. Perhaps most glaring is the study’s finding that women who decreased their physical activity after diagnosis were actually four times more likely to die of breast cancer than those who remained sedentary.

In all, exercise is an important lifestyle behavior for women undergoing breast cancer treatment.

Brain Tips for the Summer Months

Leave a reply

summer.jpgThe summer months provide a great opportunity to review the health of your brain and to get started following some of the simple steps articulated in Dr. Nussbaum’s Brain Health Lifestyle. You will soon be on your way to building brain reserve, promoting your own brain health, and enhancing your brain’s ability to delay the onset of neurodegenerative disease.

1. Get Moving!

Research indicates that daily walking, aerobic exercise several times a week, dance, gardening, and knitting all have a positive effect on the brain. It is important to note that 25% of the blood and nutrients from each heartbeat goes directly to your brain. In contrast, passivity in midlife increases the risk of dementia later in life. Get your pedometer and start moving, shaking, and planting!

2. Improve Those Eating Habits

Summer finds us on the go between events and the many activities of our children. We develop routines of eating more and more fast food and less time sitting down to eat with the family. It is important to try and promote the following:

A. Consume more water on a daily basis
B. Push the fruit and veggies
C. Minimize the fast food and processed foods
D. Try to consume more fish
E. Eat with utensils and not your fingers and you will eat less and healthier
F. Try to eat seated meal with the family per day

3. Develop a New Hobby or Two

Mental stimulation (e.g. brain fitness, brain games) remains important in the summer months. Get started on that project or activity/hobby you have been resisting. Challenge your brain to develop a new talent or skill this summer. Your brain will thank you!

4. Take Time to Slow Down

Summer can be a time of too much activity. This is not good for the brain as stress can be health demoting. Give yourself 30 minutes every day to do nothing. Learn to turn inward through meditation, prayer, being in nature, or simply taking a walk. Having time to just exist can be very rewarding and a great opportunity for creativity.

5. Have Fun with Others

Socialization is a great thing for the brain as it provides interpersonal chemistry, sharing of ideas, laughter, and learning. Recreation and family functions or adult play can be important to reduce stress and promote happiness.

Exercise May Slow Brain Disease

Leave a reply

hiking.jpgAnother study has been published that supports a relationship between physical fitness and brain volume. This study explored the rate of brain shrinkage or cell loss in persons with mild Alzheimer’s disease. Subjects had their peak oxygen demand measured while running on a treadmill and this was related to their brain shrinkage as estimated by MRI scan.

Results indicate that those persons suffering AD who were more physically fit had less brain shrinkage than less-fit participants. Curiously, these same persons did not do significantly better on tests for mental performance. The authors suggested that there were not enough participants to see the difference in cognitive performance and that the study used only one measurement point which prohibited demonstration of a conclusion.

However, this study together with other research further underscores an important relationship between blood flow, cardiac health, and brain health (e.g. brain fitness).

Sunshine on the Brain

Leave a reply

beach1.jpgThe summer months bring warm weather, blue sky, and plenty of sunshine. For some, if not most, we may notice our mood becomes a bit happier. Is there a relationship between the sunshine and our mood? Probably, but why?

Some studies have reported a relationship between Vitamin D that is derived from sunshine and different physiological measures in the human body. Sunlight has also been related to mood with a disorder known as “Seasonal Affective Disorder” in which those not exposed to enough sunlight can become depressed. Indeed, special lights have been prescribed for those with seasonal affective disorder to help their brains gain more ultraviolet exposure to lift their mood.

Sunshine also tends to come with blue sky, relates to an increased ability to get outside and move about in nature, and to recreate more. Each of these factors is important and is related indirectly to mood enhancement.

It is important to pay attention to your own mood and determine what environmental factors may help you feel happier. If sunshine and blue sky lift your spirits try to prescribe yourself increased time outside. You may feel more energy, higher sense of self and increased productivity.

How about Golf and Brain Health

Leave a reply

golfing.jpgBefore all of you jump up and down celebrating another reason to miss work and play 18, let me remind you that this particular blog is speculative with some educated guess mixed in. Having said that, I am happy to for any grant funding to study the effects of playing golf on brain health!

I began to think about the health benefits of golf some time ago, but I grew more interested during a few rounds of the game with my son. As you know, I have proposed and studied five major domains to my brain health lifestyle: these include socialization, mental stimulation (brain fitness, brain games), physical activity, spirituality, and nutrition. Golf certainly includes four of the five components and may include all five.

Golf is a game that is social. In fact, one typically plays the game with another partner and sometimes three other partners. An even more brain healthy opportunity arises when one plays the game alone and is matched with strangers to play the round. This forces a “complex and novel” environment on you that promotes brain health.

Golf is a game that certainly involves physical activity, particularly if you walk and do not ride in a cart. As 25% of the blood from each heartbeat goes to the brain there can be tremendous blood perfusion to the brain during a game of golf. This simply considers the walking and not the swinging and body motion mechanics of the golf swing.

Golf involves mental stimulation in the forms of conversation and story telling with your partners, arithmetic calculations while keeping score which can involve three digits, keeping track of your shots which demands memory, and probably trying to keep track of your partner’s shots so there is no funny business going on. There is also planning, strategy and decision making, judgment, and estimation of distance and space skills involved.

Golf can be a spiritual experience to reduce stress, have fun, slow down, and enjoy nature. Golf courses tend to provide nice scenery and a pleasant surrounding. Golf provides you an opportunity to reflect and to set priorities.

Finally, Golf can include good nutrition if the proper foods and beverages are selected before, during, and after the game. Fruits, vegetables, and fish are always great items in a brain health diet.

I believe golf is a natural activity that provides many aspects of the brain health lifestyle I have discussed and written about. So long as one does not let a poor shot or poor score raise his or her stress level too much!

Life Expectancy in the United States

Leave a reply

child.jpgRecent data indicates Americans are living longer than ever before as life expectancy hit 78.1 years in 2006. Rates for 14 of the top 15 causes of death fell in 2006 according the US Centers for Disease Control and Prevention. The most significant decline in cause of death was attributed to influenza and pneumonia that fell nearly 13% from the previous year.

Life expectancy of 78.1 is up from 77.8 years in 2005 representing a continued rise over the past decades. Women have a life expectancy of 80.7 years while men remain somewhat behind at 75.4 years. Racial disparities also exist with white women’s life expectancy at 81 years compared to 76.9 for black women. White men’s life expectancy was 76 years and black men at 70.

The top two causes of death include heart disease and cancer followed by stroke, chronic lower respiratory diseases such as emphysema and then accidents. Alzheimer’s disease, the most common form of dementia, is now the sixth leading cause of death in the U.S.

Gains made in life expectancy represent an opportunity for continued years of quality of life. Getting started earlier in life with a proactive lifestyle (physical activity, brain fitness, brain games etc.) including that designed for the heart and brain can help to maximize the quality with the increased quantity of life.

Rhythms, Nature and Brain Health

Leave a reply

waterfall.jpgThe first sound we may perceive as a budding human being on planet earth is the heart beat of our mother. Our brain appreciates rhythm and harmony for stress tends to be limited in such situations. Breathing in a rhythmical manner is taught to reduce stress. Scuba divers describe the peace of being under water when they can hear their breathing in an otherwise quiet environment. Humans continue to migrate to the oceans as a form of vacation where waves provide a rhythm. Others venture to the woods where there is little to distract an inner peace.

These are a few examples of how nature provides our brains with environments that promote rhythm and perhaps stabilize the symmetry of our two brain hemispheres. Our typical daily life takes us out of rhythm and hence causes a stressful disequilibrium in our brain. Research on animals indicates that an environment that is too stimulating leads to slowed brain development. Our challenge is to be conscious of our own daily behavior and the types of environments we expose our brains.

Make it a goal to seek out environments that promote peace and rhythms for your brain. This will help to reduce stress by reducing the amount of stimulation that is not healthy. A walk in the woods, a stroll on the beach, or even witness to a sunset can be more health promoting than you might imagine. Anytime you become conscious of your breathing and surrounding in a safe environment is typically a healthy moment.

The Importance of Sleep for the Brain

1 Reply

Sleep is a highly active time for brain development and brain function. There are four primary stages of sleep including Rapid Eye Movement (REM) when we dream and deep sleep or stage four sleep. It is thought that deep sleep and REM tend to decline with advanced age and these are perhaps the parts of sleep when consolidation of information takes place. As such sleep quantity and quality have a major role in what and how well we process and remember information.

REM sleep occupies about 25% of our total sleep and it is during REM that we dream. We tend to be paralyzed during this part of our sleep so we cannot act out our dreams. Without REM and deep sleep we can become lethargic, depressed, and make mistakes. Significant sleep disorders affect more than 35 million Americans and many more around the world. Sudden sleep is known as narcolepsy and can occur while driving which leads to a high number of fatal car accidents. Sleep Apnea, the first phase of narcolepsy, occurs because of a blockage of the airway and results in sudden gasps for air while sleeping. Apnea is most common in middle age, obese and hypertense males.

When considering lifestyle changes for brain health (e.g. brain fitness, brain games), one of the most important aspects of life is sleep. We tend to not get enough sleep and our brains run on fatigue much of the time. Napping is a lost art and we do not rest enough. As a result, our brains are over-stimulated, stressed, and tired. Consider this blog a permission slip to get a good night sleep and to take a nap sometime this week.

Wine Consumption and Health

2 Replies

A recent study has supported a relationship between an important ingredient in red wine and retardation of the aging process. Resveratrol, an ingredient of some red wines may have some life extending effects in mice and maybe in humans. The mechanism in play is switching the body’s resources from fertility to tissue maintenance. The improved tissue maintenance appears to extend life by reducing the degenerative diseases of aging.

Scientists believe this switching mechanism can be induced by a faminelike diet, known as caloric restriction that extends the life of  rodents by up to 30 percent, but similar effects in humans are not conclusive. Resveratrol has been shown to increase strength, endurance, and speed of lab mice. Findings from studies suggest resveratrol may be effective in mice and humans in smaller doses than previously known. Studies suggest a significant positive effect on aging in mice with dosages that mimic 4-5ounces of wine daily. Researchers believe resveratrol can mimic many of the effects of caloric restriction at doses that can be easily achieved by humans.

So….if you are not predisposed to alcoholism and your doctor has not restricted you from alcohol, one 4-5 ounce glass of red wine a day may indeed promote a healthier aging process.

Social Status and Brain Health

1 Reply

The Washington Post reported on a recent study out of the National Institute of Mental Health. The study found that different brain areas are activated when a person moves up or down in social status or sees people who are socially superior or inferior. The brain seemed to activate in a similar manner to winning money.

The scientists indicate that our position in social hierarchies affects motivation as well as physical and mental health. Past research has supported the relationship between social rank and health. For example, persons with a lower social status had a higher risk of developing cardiovascular disease and to die early. Psychological effects to include loss of control over one’s environment may be one trigger for the relationship to poor health.

The brain seems to have a hard wiring for hierarchical information and that this information is important to us. Our desire to compete, play to win, and to be motivated are directly linked to brain circuitry.

This most likely explains our civilization’s interest in sports, gaming, and competition. Our own individual struggle to reach our specific potential in areas of school, work, or skill development also fit into this model. It may not be such a stretch to suggest that our drive to personal health, including brain health involves such brain circuitry and that computerized mental exercises that provide explicit feedback on our performance is one tangible example of competitive health behavior.
