The Broken Brain on-line “docuseries” is running now.

I would encourage everyone to watch this series of daily interviews and discussions on lifestyle and brain health. This was organized and produced by Mark Hyman MD, director of the Functional Medicine Clinic at Cleveland Clinic, well known author, speaker and physician, Discussions cover many topics including environmental toxins (such as heavy metals and Roundup), nutrition, exercise, sleep, stress reduction, gut bacteria, and more with specific reference to the effects on your brain and risk for dreaded conditions such as Alzheimer’s and other forms of dementia, Parkinson’s disease, multiple sclerosis, etc. These conditions can be prevented and when present, they can be treated with interventions not usually employed by modern medicine, unless you are fortunate enough to be working with a Functional Medicine practitioner.

You can sign up to receive a daily email with a link to the on-line video. Each video in the series is available for 24 hours starting at 3 PM PST, 6 PM EST.

Here is the link to get started with the third episode in this series.

Cartoon humor: A Prescription for Health!

 

prescription-for-exercise-cropped

Hat tip to Tommy Wood MD, PhD for introducing me to this great cartoon.

So what would happen if your doctor prescribed this? Would you be shocked? Would you follow the advice? Sadly few doctors make such recommendations as explicitly as this cartoon and fewer patients follow the advice.

How important are the elements in this advice?

They are essential. We too often focus on dietary concerns at the expense of ignoring other important low hanging fruit. Early morning  outdoor exercise with exposure to natural light in a green space, even on a cloudy or rainy day, is essential for health. Why? There are many reasons. Click the link above to read fitness expert Darryl Edward’s discussion with references. In fact outdoor exercise in a greenspace is more beneficial than the same exercise indoors. The reasons are many, including but not limited to Vitamin D production.

Early daytime exposure to natural outdoor light helps to maintain our Circadian rhythm and align the biologic clock in all of our cells and organs with the central biological Circadian clock in our brain. Most folks do not know that we have a biologic clock deep within our brain and that all the organs and cells of our body also have clocks. They all need to be synchronized with each other and with the sun for optimal health. When they are not synchronized bad things happen. Night shift workers and other folks with disturbed sleep have higher rates of cancer , depressionhypertension, heart attack and stroke.

Maintaining our circadian rhythm is vital to achieving adequate high quality restorative sleep. In turn, obtaining adequate restorative sleep contributes to lower cardiovascular disease risk in addition to four traditional lifestyle risk factors.

Exposure to artificial light at night disrupts our circadian rhythm and impairs the onset of sleep.

In medical school I learned that our retina has two cell types, rods and cones. But advances in science have revealed a  third cell type called retinal ganglionic cells. 

These cells are  particularly sensitive to blue light and directly connected to our central biological clock . Exposure to artificial light, especially from TV screens, computers, cell phones and other electronic devices after sunset disrupts our sleep cycle and delays the onset of sleep. That is why wearing blue light filtering glasses in the evening helps many folks to improve their sleep quality and duration.

Sleep deprivation for even one night causes elevation in interleukin 6 levels the following day. Interleukin 6 suppresses immune function and excessive levels cause bone and tissue damage (especially cardiovascular). Sleep deprivation  increases  Stress hormones (cortisol, adrenalin), decreases prolactin and Growth hormone , and decreases the nightly production of ATP .

Melatonin , often called the sleep hormone, is produced most abundantly during restorative sleep and essential for tissue healing, immune function, cancer prevention, and defense against tissue oxidation. These are just a few of the roles melatonin and sleep cycles play in determining our health..

So exercise outdoors in a green space daily to help synchronize your biologic clock with the sun, dim the lights in the evening and if you must watch TV or work on electronic devices before bed wear Blue Light filter glasses .

Of course eating an abundance of colorful fresh organic vegetables and fruits, and practicing some stress reduction techniques every day are equally important and essential to health and functional status.

Finally, not mentioned in the cartoon above is another healthy lifestyle choice, intermittent fasting (IF). IF will be discussed in the next post.

Until then, sleep well, exercise regularly out doors in a green space environment, eat clean, learn and practice some regular stress reduction techniques and read the next post about IF.

Functional Medicine: Getting to the Root Causes of Illness, A cure for Alzheimer’s

Today I watched a great TED talk by Dr. Rangan Chaterjee discussing his own journey in the discovery and implementation of a functional medicine approach to caring for his patients. The concept of using basic science and clinical science to diagnose and treat the root causes of illness, rather than treating symptoms, has been around for more than two decades.  This approach has recently started to attract more attention, especially within the community of younger physicians who have become more dissatisfied with the frustrations of traditional allopathic medicine.

Here is the talk. Dr. Chatterjee covers lots of ground in a passionate and informative talk.

Enjoy this talk. If you would like to learn about how a functional medicine approach can CURE ALZHEIMER’S DISEASE then watch this video of Dr. Bredesen who gave this lecture at a meeting of the American College of Nutrition.

Doctor Bredesen, an acclaimed neuroscientist, researcher, and more recently a brilliant clinician, has been criticized by the academic research community for implementing a clinical research protocol that addresses more than one variable at a time! Unfortunately, medical science has been handcuffed by the drug-model of clinical research wherein only one variable (drug vs. placebo for example) is studied. But if an illness has many potential contributing root causes, changing only one variable is doomed to failure, as Dr. Bredesen explains in this lecture.

Sleep well, eat clean, get outdoors every morning to help keep your circadian rhythm and biological clock in order.

Nutrition Journals and the influence of the food industry

Ever wonder why the public is so confused about nutrition recommendations? Just follow the money and you will understand that most of the professional societies that publish nutrition articles are funded by big food companies that are trying to sell more sugar, refined carbs and junk food. I recently read an excellent post about this topic here:

The Vilest Villain: American Society of Nutrition

This theme is repeated by medical journals that are “The Official Journal of the Society of >>>>>>” Just fill in the blanks for just about any medical society. Funding comes from big pharmaceutical companies the same way that funding in the nutrition Journals comes from large (junk) “food” manufacturers.

Don’t get me wrong, there are plenty of very valuable, life-saving drugs out there.

But most chronic human disease in developed societies is generated by various combinations of poor nutrition, lack of exercise, disruption of circadian rhythm, inadequate restorative sleep, stress and lack of social support systems.

The obesity and diabetes epidemics continue to worsen yet the failed dietary advise of major health organizations is slow to respond to the data. Excess refined carbs (especially in the form of “food” made with flour) and added sugar (especially in the form of HFCS) are the major driving forces for obesity, diabetes and cardiovascular disease. Red meat is not the culprit, provided the meat is properly sourced (hormone and antibiotic free, grass fed) and cooked in a manner that does not create carcinogens and inflammatory mediators (cook with slow, low, moist heat, high temperature grilling and smoking cause problems, but that topic  is for another post).

Americans consume an average 130 pounds per year of added sugar and 140 pounds per year of refined flour. Those are averages so there are many people who consume more. The added sugar is not the white stuff people put in their coffee. It comes in all sorts of forms but is found in energy drinks, soda, lattes and mochas, salad dressing,  ketchup, canned soups, canned vegetables, white AND whole grain breads, pasta (even “whole grain”), crackers, breakfast cereal,  just about any packaged food that has more than one ingredient on the label. These foods represent 70% of the American diet. The problems created by this situation are enormous and will bankrupt our “healthcare system”. This is a cultural and economic problem.

The solutions are simple but largely ignored in our society. We are creatures of habit and convenience.

Eat whole foods, nothing from a package that has more than one ingredient. Eat meat, seafood, poultry, fresh organic vegetables (6-9 servings per day), fresh organic fruits, and nuts. Meat should be hormone and antibiotic free (free range, grass fed). Seafood should be wild. Poultry should be free range and the eggs should come from free range chickens, ducks, geese.

Do not worry about eating fat as long as it comes from healthy animals and sources such as coconut oil, extra-virgin olive oil, avocado oil and clarified butter (ghee).

Do not use any “vegetable” oils (corn, soy, and other oils from grains or seeds) The vegetable oils are highly refined and inflammatory. They contain easily oxidized omega 6 fats that feed the production of inflammatory mediators in your body and create oxidized LDL leading to atherosclerosis.

Exercise daily, preferably outside in a green space. Twice per week spend 20-30 minutes  doing resistance training (lift weights, work against the resistance of bands, use your own body weight doing pushups, pull-ups etc)

Reduce stress with mediation, yoga, tai chi, dancing, engaging in fun sports and social activities. Walk on the beach, by a lake, river or stream, in the woods, listen to music.

Get some sunshine regularly especially during the morning to get your circadian rhythm in order and to produce adequate amounts of vitamin D.

Spend time with family, friends and colleagues who are supportive and fun to be around.

Sleep in the dark.

Get at least 7 hours of sleep per night. Avoid TV, computer screens and other electronic devices for at least 2 hours before bedtime.

Unplug from the internet, email, etc on a regular basis.

We evolved as hunter-gatherers.

Chronic Pain: How does it occur and what can be done about it?

I have discussed the effects of nutrition, stress-reduction, sleep, and circadian rhythm on pain in previous posts . I have not yet discussed the theory of how chronic pain develops and persists. This post discusses some of the mechanisms involved in chronic pain as well as therapeutic approaches that have proven to be effective in addressing the root causes of chronic pain and suffering.

THE CENTRAL NERVOUS SYSTEM (BRAIN AND SPINAL CORD) CAN INDEPENDENTLY CAUSE PAIN AND OTHER PHYSICAL SYMPTOMS THROUGH THE DEVELOPMENT OF LEARNED NERVE PATHWAYS. THESE PATHWAYS INCLUDE CIRCUITS WITHIN THE BRAIN AND CIRCUITS CONNECTING THE SPINAL CORD TO VARIOUS PARTS OF THE BRAIN. THEY CAN PRODUCE PAIN EVEN IN THE ABSENCE OF ONGOING TISSUE DAMAGE.

THESE LEARNED NERVE PATHWAYS CAN DEVELOP AS A RESULT OF SEVERAL WEEKS OR MONTHS OF CONTINUOUS PAIN CAUSED BY AN INJURY OR DEGENERATIVE-INFLAMMATORY DISEASE. IF WE EXPERIENCE RELENTLESS PAINFUL IMPULSES COURSING THROUGH THE BODY THESE BOMBARD THE SPINAL CORD AND BRAIN WITH PAINFUL MESSAGES AND OUR BRAIN AND SPINAL CORD EXPERIENCE A CHANGE SIMILAR TO THE CHANGES THAT CAN OCCUR WITH PTSD CAUSED BY ONE OR MORE TRAUMATIC EVENTS.

THESE LEARNED NERVOUS SYSTEM PATHWAYS REPRESENT “NEUROPLASTICITY” MEANING CHANGES IN THE NERVOUS SYSTEM BROUGHT ABOUT BY EVENTS SUCH AS TRAUMA AND STRESS. THEY REPRESENT A “MEMORY” OF THE PAIN, TRAUMA AND STRESS IMPRINTED ON THE NERVOUS SYSTEM. THIS “MEMORY” INCLUDES NEWLY (AND OFTEN PERMANENTLY) FORMED CIRCUITS THAT OFTEN CONNECT VARIOUS PARTS OF THE BRAIN ASSOCIATED WITH PAIN, ANXIETY, DEPRESSION AND ANGER TO PARTS OF THE BRAIN AND SPINAL CORD THAT MEDIATE SENSATIONS OF LIGHT TOUCH AND PRESSURE. THESE CONNECTIONS PRODUCE “ALLODYNIA” WHICH IS A PAINFUL RESPONSE TO A STIMULUS WHICH IS USUALLY NOT PAINFUL. WE CAN ALSO EXPERIENCE “HYPERALGESIA” WHICH IS AN EXAGGERATED PAIN EXPERIENCE, OUT OF PROPORTION TO THE PAINFUL STIMULUS.

THE NERVOUS SYSTEM HAS A BUILT IN “MUFFLER” DESIGNED TO DAMPEN DOWN PAIN MESSAGES BUT IN CHRONIC PAIN THIS MUFFLER BECOMES AN AMPLIFIER THAT NOT ONLY AMPLIFIES THE TRANSMISSION OF PAIN BUT ALSO CONNECTS THIS AMPLIFIED PAIN SYSTEM TO PARTS OF THE BRAIN ASSOCIATED WITH ANXIETY, ANGER, AND DEPRESSION.

ONCE THESE CIRCUITS OR PATHWAYS ARE IN PLACE (“LEARNED”) THEY CAN NOT BE ELIMINATED (“UNLEARNED”). EFFECTIVE PAIN REDUCTION REQUIRES ACTIVATING ON A REGULAR BASIS ALTERNATIVE PATHWAYS THAT ALREADY EXIST SUCH AS THOSE ASSOCIATED WITH PLAY, MUSIC, DANCE, HUMOR, LAUGHING. ACTIVATING OTHER PATHWAYS CAN ALLOW THE PAIN PATHWAYS TO BE “TURNED OFF” OR MUFFLED. AS CHILDREN WE LEARN TO PLAY AND THOSE LEARNED PATHWAYS STAY WITH US FOR LIFE. WITH PRACTICE WE CAN REGULARLY ACTIVATE THOSE BRAIN PATHWAYS AND MAKE THEM AND OTHER PATHWAYS THE PREDOMINANT PATHWAYS OF OUR BRAIN ACTIVITY.

BUT BEFORE WE CAN UTILIZE THE PLEASANT ALREADY-LEARNED PATHWAYS IN THE BRAIN TO CIRCUMVENT THE PAINFUL-ANXIOUS PATHWAYS WE MUST FIRST DEAL WITH OUR ANGER. DEALING WITH OUR NATURAL AND JUSTIFIABLE ANGER REQUIRES FORGIVENESS. UNTIL THE ANGER IS RELEASED AND FORGIVENESS ACHIEVED WE CANNOT MAKE USE OF THE THERAPIES AND STRATEGIES AVAILABLE TO DECREASE AND MANAGE OUR PAIN. ANGER BLOCKS THE PATH TO HEALING AND PAIN REDUCTION.

The brain processes an emotional insult in exactly the same way that the brain processes a physical insult. Stressful life events and our emotional reactions to them may cause pain that is severe. This is why chronic pain becomes worse when we experience a stressful event. Vicious cycles develop as multiple circuits connecting pain pathways to areas of the brain associated with anxiety and depression become activated and stay activated.

COGNITIVE BEHAVIORAL THERAPY: Over the course of months and years, our reaction to chronic pain often includes repetitive negative thoughts. Cognitive behavioral therapy helps us learn techniques to avoid repetitive negative thoughts.

Mindfulness Based Stress Reduction is another technique that can help mitigate the suffering associated with pain. Mindful Meditation practiced 30 minutes per day produces measurable changes in brain activity that can be seen on Functional MRI scans of the brain within 90 days. These changes demonstrate decreased brain activity in areas associated with pain, depression, anxiety and anger. Scientific studies have also demonstrated that MBSR produces improved immune function, reduces blood pressure, reduces heart rate, improves sleep and provides other beneficial physiologic changes associated with healing and wellness. Yoga and meditation are essential components of an MBSR program.

SLEEP: Pain cannot be managed or successfully treated unless an individual gets 8-9 hours of restorative sleep per night. Sleep hygiene recommendations are an essential part of the path to wellness. Daily exposure to sunlight outdoors and restoring normal circadian rhythm are essential for pain management. Going to bed at the same time every evening and sticking to a regular schedule is the most important part of improving sleep. Daytime exposure to sunlight and dimming the lights in the evening are also required. Regular exercise (daily walking) is essential. Wearing blue-light blocking glasses for 2-3 hours before bedtime can facilitate sleep. When blue light wavelengths (light bulbs, computer screens, TV screens) hit the retina of the eye a message is immediately relayed to the “internal clock” of the brain that tells the brain there is still daylight. This inhibits the production of melatonin (the “sleep hormone”). Avoiding bright light (especially from TV or computer screens) for 2-3 hours before bedtime is important. If you must watch TV or work on the computer in the evening that blue light blocking glasses or goggles are a must. There are free software programs that will eliminate the blue light from your computer screen as an alternative to blue light blockers.

NUTRITION: Pain involves inflammatory pathways. An anti-inflammatory diet is essential for treating pain and providing the nutritional components necessary for healing tissue and establishing better brain chemistry. Paleo Diet removes potential sources of inflammation from the diet. If a patient suffers from an auto-immune disorder the more restrictive Autoimmune Protocol version of the Paleo-diet can help put the disease into remission and decrease the inflammation associated with the auto-immune process.

OBESITY AND OVERWEIGHT: Extra fat around the belly and internal organs causes chronic inflammation throughout the body. The fat cells around internal organs and the immune cells that reside alongside the fat cells both produce a steady stream of chemicals that circulate throughout the body stimulating inflammation everywhere. These circulating chemicals are called cytokines and chemokines. Certain cytokines and chemokines cause fatigue, brain fog, and sensitize the nerves, increasing pain. They also interfere with sleep. Weight loss is an essential component to pain reduction for overweight and obese patients. The best nutritional approach to weight loss includes a Paleo Diet with carbohydrate restriction (low carbohydrate, high-healthy-fat whole food diet). Adding medically supervised intermittent fasting (such as an 18- 24 hour fast every 1-2 weeks, consuming only water for 18-24 hours) can also be effective especially combined with a carbohydrate restricted Paleo Diet and lifestyle.

Exercise and Physical Conditioning: Chronic pain causes sedentary behavior which results in physical de-conditioning. This process involves loss of muscle, decreased bone density, shortening of ligaments and tendons and shrinkage of the tissues that envelope muscle. This leads to more pain when physical activity is increased and a vicious cycle is created. This cycle must be broken with a graduated daily exercise and physical conditioning program. If you follow a medically prescribed exercise program you will not damage your body even though it may be painful during the first several days. Exercise also helps to convert the “amplifier” back to a “muffler” in the nervous system.
