Medical Myths about Aging

Medical myths about aging are easy to debunk. Many people believe that it is inevitable that they become disabled as they age, their lives become unbearable, without passion, boring and full of pain. Some aspects of your health may decline with age, none of the myths discussed below is inevitably happening in everyone. Studies showed that a positive outlook on aging and life in general will help you to live longer and stay healthier.  Here I discuss 7 common myths about aging.

Myth 1: Everyone will experience physical deterioration

It is common for people to experience reduced muscle strength, increased blood pressure, excessive fat accumulation and osteoporosis. A study with 148 older patients showed that an expectation of reduced fitness in older age actually resulted in less physical activity when older age arrived.

But you can maintain good cardiovascular function and good muscle strength with a regular exercise program.  This study showed that men and women can reduce mortality by exercising regularly, even in older age.

Myth 2: Older adults cannot exercise

There are several reasons why older people stop exercising or are afraid to start exercising. People use the excuse of their arthritis getting worse from exercise. But studies showed the opposite: joint function improves and joint pains are getting better with exercise. Your muscles get stronger and you are less likely to fall. Your heart and lungs are improving their functions and your mentation improves. Exercise increases the HDL cholesterol, which reduces the risk for heart attacks and strokes.

Myth 3: As we age, we need less sleep

For many years there was the notion that older people need less sleep. What was not known then was that people above the age of 60 have no appreciable secretion of melatonin from the pineal gland. But when they replace their melatonin deficiency by taking a nighttime dose of 3 mg at bedtime, they will sleep better and longer. They may need a second dose of melatonin in the middle of the night. We need 7 to 8 hours of sleep at night for our diurnal hormone rhythm.

This will also slow down our aging clock.

Myth 4: Your brain slows as you age

Dementia is common when you get older. 13.9% have it at age 71 and older. 37.4% have dementia over the age of 90. But the majority, namely 86.1% in the 71+ age group and 62.6% above the age of 90 do not have dementia. A Mayo Clinic study showed that when the person engaged in artistic activities in midlife or later in life the risk for mild cognitive impairment (MCI) development was reduced by 73%, involvement in crafts reduced it by 45% and engagement in social activities by 55%. In a surprise finding the use of a computer late in life was associated with a 53% reduction in MCI development. These are very significant observations.

Physical activity reduces risk for dementia

Apart from stimulating your brain, physical activities also significantly reduce the risk for dementia. A synopsis of 11 such studies showed that dementia is reduced by 30% when physical activity is started in midlife and the person is aging compared to non-exercisers.

Myth 5: Osteoporosis occurs only in women

There is a serious misunderstanding about osteoporosis. Several factors work together that can cause osteoporosis. Women in menopause are more likely to develop it due to the missing ovarian hormones estrogen and progesterone. These hormones work together and stimulate vitamin D induced calcium deposition into bone as well as decreasing bone resorption.

Vitamin K2 also deposits calcium into the bone. In postmenopausal women who take bioidentical hormone replacement, vitamin D and K2 the bone density remains strong. Unfortunately, the opposite is true in postmenopausal women who take synthetic hormones. Synthetic hormones have side chains that do not fit the natural hormone receptors of a woman. This is why osteoporosis persist. And, yes, men get osteoporosis, but typically 10 years later. Typically, they get into andropause where testosterone production declines 10 years later.

Myth 6: People stop sex as they age

With age men can develop erectile dysfunction (ED) and women vaginal dryness, both of which can interfere with having sex. A large study showed that only 0.4% of men in the age group 18-29 had ED. In the age group of 60-69 there were 11.5% who suffered from ED. What this means though is that 88.5% of men age 60-69 did not suffer from ED. Fortunately for those who have ED drugs like Cialis and Viagra can correct their problem and they can have regular sex. What a change from 25 years ago when none of these drugs were available (approval of Viagra by FDA in 1998 and of Cialis in 2003).

Bioidentical hormone replacement beyond menopause and andropause preserves your normal sex drive as well. There are additional benefits of bioidentical hormones. They have positive effects on the heart, brain, bones and the muscle mass.

Myth 7: It is too late to stop smoking now

One of the myths that many older smokers like to say is that it would be too late to stop smoking. They think the damage to heart and lungs is permanent and quitting now is too late. Fact is that quitting smoking immediately improves your blood circulation and gives you more oxygen. In just 1 year the risk of getting a heart attack is cut into half. In 10 years, the risk of a heart attack or stroke is the same as that of non-smokers. There is a reduction of getting lung cancer by half.

Conclusion

There are all kinds of medical myths about aging. We may think that physical deterioration is inevitable. Or we believe that older people cannot exercise. And we cannot help it, but our brain slows down as we get older. And there is the question whether we need less sleep as we age. Osteoporosis is a disease of women, is it not? These older couples, they don’t have sex any more, do they? And is it too late to stop smoking now that I am 65 years old? All of these myths exist, but there is a need to debunk them.

The truth behind the medical myths about aging

I explained in detail what the medical truths are behind these questions. Many of these myths have developed in the past. But with regular exercise, balanced nutrition (Mediterranean diet) and a positive attitude much of these old myths can be overcome. Bioidentical hormone replacement when hormones are missing is another powerful tool. Yes, we all age. But we are still living and can enjoy life as long as it lasts.

Coffee, Tea, Vitamin C And E Prevent Stroke And Dementia

Elizabeth E. Devore, ScD, now with Brigham and Women’s and Harvard Medical School, did a long-term study involving 5,395 people aged 55 and older who were part of the long-term Rotterdam Study of medical conditions and other factors in older adults. Over the 14-year observation period 601 patients developed strokes and 599 patients developed dementia. Detailed dietary questionnaires were available from the study that helped the author to detect what the protective factors were in those who did not develop strokes or dementia. When all other factors were excluded (including tea and coffee consumption) and only anti-oxidant factors were looked at, it turned out that there was no difference in terms of stroke or dementia rates when the lowest and highest percentiles of antioxidant groups were compared. But when the lowest and highest percentiles of tea and coffee consumers were analyzed and compared, about 90% of strokes and of dementia disappeared meaning that tea and coffee consumption is protective for both.  Dr. Devore explained that other studies have shown that vitamin C helps prevent strokes and vitamin E helps to prevent dementia and that both vegetables and fruit as well as tea and coffee have been shown in other studies to help reduce both.

Here is another article that investigated the role that vitamin E plays in reducing brain aging and preventing dementia and Alzheimer’s.

In a long-term study (over 20 years) vitamin C was shown to help prevent hemorrhagic and embolic strokes.

Vitamin C and E are not the only beneficial vitamins for the brain. Vitamin D3 can help prevent thromboembolic strokes as the Honolulu study going on for 34 years showed.

What about coffee and tea? There is a 10-year study involving 32,600 women where 1 or two cups of coffee per day led to a 25-32% reduction of strokes compared to non-coffee or tea consuming controls.

Males also experience a reduction of thromboembolic strokes with tea or coffee consumption. There has been a Finnish study that consisted of 29,133 smokers (smoking 5 cigarettes a day) aged 50 to 69 who were stroke free when entering the study. It ended in 1993 and had lasted for at least 5 years. Drinking two cups of black tea or 8 cups of coffee reduced the stroke risk by 21 to 23%.

Fruit and vegetables contain a lot of vitamin B complex. As this link shows vitamin B can lower cysteine, a blood component that contributes to heart attacks and strokes.

So, what should you do to prevent strokes and dementia?

Stop smoking, if you do. Avoid alcohol and drugs as much as you can. Your brain cells have very sensitive mitochondria that give you energy, but they are very sensitive to toxins. Avoid brain injuries like concussions as they can accumulate and lead to dementia. Whatever you can do for your heart is good for stroke prevention such as weight loss (down to a body mass index of 22.0), exercise, and sensible food intake (complex carbs, cut out sugar, have lean meat, more chicken, turkey, lean pork, only occasional beef). Take multiple vitamins including B, C, D3, E and drink tea or coffee. Some health oriented people may not want to hear this latter point (tea, coffee), but the studies show it is brain and heart protective.

Survey Shows People Underestimate Lifestyle Factors As Cancer Causes

Roy Morgan Research Company and Gallup International have released an opinion poll study at the recent International Union Against Cancer’s World Cancer Congress in Geneva (August 27 to 31, 2008) that reveals significant differences among low-income countries and high-income countries. Cancer of the liver and other cancers can be caused by alcohol and throat and lung cancer as well as others are caused by carcinogens from cigarette smoking. These are medical facts that have been well established. But the opinion poll showed that there is ignorance and confusion in the public both in poor and wealthy nations. For instance in high-income countries 42% felt that there was no cancer risk from drinking alcohol and 8% were unsure, in low-income countries 15% were of the opinion that alcohol was not a cancer risk and 29% were unable to say. Other differences were that 62% of people in wealthier nations believed that cancer was one of the three top health issues in the country, while only 36% of people in poorer nations believed this. On the other hand with so much information about pollution in the press 76% to 78% of people living in middle and high income countries are of the opinion that this is an important cause of cancer while only 30% believe this in the poorer countries. The reality is that smoking and drinking of alcohol are more important in terms of cancer causation than pollution is.

David Hill, president-elect of the International Union Against Cancer, said that these opinion polls reveal data about attitudes and believes previously unknown. This kind of data can be used to formulate programs for cancer prevention so that the public is accurately informed about cancer facts and they learn in rich and poor countries alike that factors like smoking, drinking alcohol and a high body mass index are more significant cancer causes than pollution. Pollution is more difficult to control by the individual, but these life style factors can be modified, and people need to be empowered to make the right choices. People have the power to stop smoking, to cut down their alcohol consumption and to increase their exercise, which helps them to shed pounds.
