With regard to the human brain we can provide general advice about how to promote brain health across the lifespan. When we were cavemen and cavewomen we ate one good fat for every bad fat. Today, we eat about 15 bad fats for every good fat. This is important because our brains are composed of about 60% fat and the lipid substance helps to facilitate information processing.
Thinking live a cave person might be a good exercise when thinking about what to eat. We should try and eat plants/vegetables, nuts, beans, fruit, fish, and lean game such as chicken. We should try to reduce processed foods, red meat, trans fatty acids, soda and foods high in sugar. We should strive to eat less than more and use utensils more often as it might help to less consumption of food and a healthier consumption of foods.
It is also important to realize that foods are supposed to be pleasurable and that an occasional piece of cake, pie, ice cream, etc will not cause major damage to the system. This is particularly true when one follows some of the general advice above.
I personally have begun a study of my own diet with increased intake of fruits and vegetables, reduction in processed fats, removal of soda from the diet, and increased fish and lean chicken. It is not uncommon for me to now have fruit in the am and day with a salad (olive oil and vinegar are good for the brain), and a piece of fish or chicken at night. I have been relatively consistent though I fail now and then. I am observing change in body mass and in psychology including energy and mental alertness.
Stay tuned and I will provide you an update in the near future!
Recent 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.

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.
A recent report from the National Alzheimer’s Disease Association estimates nearly 10 million to 14 million of the baby boom generation (76 million strong) will be at risk for developing Alzheimer’s disease (AD). These numbers may actually underestimate the overall prevalence of boomers who will develop AD in their lifetime. This estimate places a heavy emotional, family and economic burden on the U.S. States given our current approach and over all understanding of the caregiver demands posed by AD. There is no reason to believe that similar nations across the world will be any different.
One method to begin addressing the rising epidemic of dementia is to establish a national or world priority on the human brain and dementia. Citizens of the great planet Earth need to have a basic understanding of their brain, something that is completely missing even in 2008. We cannot expect citizens to care for their brain if they do not understand it or the importance of a proactive healthy lifestyle across their lifespan. One idea is to include basics of brain and brain health in every elementary curriculum in the world.
National policy also has to prioritize research on treatment and prevention of dementia in ways we have not yet. Research is needed on how the brain functions, how diseases begin, new treatments for dementia, and innovation in the area of prevention. Health insurance companies should begin to incentivize lifestyles that promote brain health including lifelong learning, diets, meditation, and physical exercise. Those who continue to work or remain involved in society may be rewarded with some type of tax break. We need to think in terms of a Brain Enlightened Society.
Nearly everyone experiences the inability to recall a name or to struggle trying to find the correct word. These moments are referred to “tip of the tongue” phenomena and can be quite frustrating. The good news is that word finding problems is not necessarily a sign of pathology or disease, and indeed likely represents changes that occur with the normal aging process.
Around the age of 50 our brains begin to change structurally and functionally. We lose brain cells over the lifespan with a disproportionate number of cells lost in the frontal lobes. These are normal changes and the functional change associated with aging is also considered normal. We tend not to freely recall information, our information processing speed slows, and we may struggle with word finding. Once again, these are typically considered normal changes with aging and it is most common to experience such changes around age 50.
I believe that brain exercise, particularly in the cognitive areas listed above, can help to keep these functions relatively sharp and maintained. Passivity certainly will not help the brain and indeed it may exacerbate the changes in our cognitive processes.
