Dementia From Excessive Alcohol Abuse

A new study from France documented dementia from excessive alcohol abuse. One million patients who needed admission to hospitals in France for early dementia took part in that study. This was based on this publication. Dementia is a clinical syndrome, where the cognitive ability deteriorates progressively.

The study from France regarding dementia from excessive alcohol abuse

According to the French National Hospital Discharge database it was especially relevant that alcohol use disorders were present in 16.5% of the men and 4% of the women with dementia. Those who did not have the diagnosis of dementia had only half the amount of alcohol abuse disorders in both sexes.

There are other diseases that can lead to dementia like Parkinson’s disease and Huntington’s disease. These cases were not part of this study.

The association with alcohol abuse was particularly evident in early dementia cases at an age below 65.

Furthermore, alcoholics also have a shorter life expectancy.

Several mechanisms responsible for dementia development

Alcohol can cause dementia in several ways.

  • First of all, alcohol and the metabolic by-product acetaldehyde have toxic effects on the brain. They cause long-term toxic effects and functional brain damage is the result.
  • Furthermore, heavy alcohol abuse leads to liver damage with resulting changes in metabolism. Ammonia production from the cirrhotic liver causes brain damage in a condition called hepatic encephalopathy.
  • In addition, heavy drinking is a strong vascular risk factor. This leads to diabetes, high blood pressure, heart attacks and strokes.
  • Often it is the population group that is uneducated, people who smoke and people with depression who suffer from the effects of alcohol abuse.
  • Finally, heavy drinking is more frequent in men than in women. In men the dementia risk was 4.7-fold, in women 4.3-fold.
  • Obesity, smoking and high blood pressure are also risk factors for dementia. If these cases were not part of the study, heavy alcohol abuse caused an increase in dementia in both sexes by a factor of 3-fold.

Possible biases of the study

Dr. Kostas Lyketsos, a neuropsychiatry professor and director of the John Hopkins Memory and Alzheimer’s Treatment Center did not take part in the study and its investigation. A non- biased observer, Dr. Kostas Lyketsos stated that there is a problem with precision of the data the larger the study population is. In this case there were more than 1 million participants, so a number of biases can influence the outcome of the study. For instance, one problem is that these patients with mild cognitive impairment were inpatients in a hospital. Normally such patients would not be in a hospital. Another fact was that none of the participants had received questionnaires of the amount of alcoholic drinks they consumed, and as a result it is difficult to knows exactly how high the amount of alcohol was that caused the damage to the brain.

Country bias

The large sample size was from only one country, France. This means that we do not know whether there would be ethnic differences between countries. Nevertheless the findings of this study are important. In a 2014 review by the WHO the average person in France consumed 12.2 liters of pure alcohol per year. In contrast the average person in the US consumed only 9.2 liters of pure alcohol in this year. Apart from these concerns it is important to realize that alcohol has toxic effects on the brain. This can also result in dementia.

Other studies regarding alcohol abuse and dementia

The media has praised alcohol for preventing heart attacks. On the other hand, there are other articles in which we hear about alcoholic hepatitis and liver cirrhosis, both of which can be killer diseases. To get some clarification, let us examine the various facts.

Dr. Finnel mentioned that 7.9% of all emergency room visits in the US are due conditions which have an association to alcohol(Ref.1). When the causes of deaths  that are a consequence to alcohol are listed, they are: cancer of the mouth and pharynx, alcohol abuse disorders, coronary heart disease causing heart attacks, cirrhosis of the liver, traffic accidents, poisonings, falls and intentional injuries. You don’t get that from the news. Instead you read about the one glass of red wine per day that is good for women and up to two glasses of red wine that is good for men to prevent heart attacks and strokes.

Bioflavonoids

It is the bioflavonoids and among those in particular resveratrol, that are the active ingredient responsible for heart health.

Resveratrol is a powerful antioxidant that protects against ischemia-reperfusion injuries.  It is responsible for the cardio protective properties of red wine known as the “French paradox” (Ref.2). According to this reference resveratrol contributes to at least 3 processes that stabilize the metabolism.

Toxicity of alcohol

According to the WHO 5.9% of all deaths worldwide is a consequence of alcohol overconsumption.  In 2012 the WHO recorded that 7.6% of deaths in males, but only 4% of female deaths were due to alcohol. Toxicity comes from the breakdown product acetaldehyde, which all cells can convert from alcohol. Liver cells are especially able to do that. According to Ref. 3 alcohol diffuses easily through all of the cell membranes and reaches every organ in the body. The toxicity of acetaldehyde is shutting down the mitochondria, which affects the energy metabolism and causes cell death. The immune system reacts with inflammation, when it attempts to repair the damage.

So, what are the major damages which alcohol can cause? First there is fat accumulation (steatosis), next chronic inflammation followed by necrosis (dying of cells) and finally fibrosis. An example of fibrosis is liver cirrhosis, where non-functioning connective tissue replaces liver cells.

Different tissue sensitivity to alcohol

Certain tissues are more susceptible to alcohol toxicity than others. As the concentration of alcohol is highest in tissues that are in direct contact with alcoholic drinks, cancers related to alcohol consumption develop in the oral cavity, pharynx, larynx, esophagus, and in the colon and rectum. The pancreas is particularly vulnerable to inflammation and fibrotic changes with degeneration into cancer of the pancreas. The heart tissue and the arteries are very sensitive to alcohol.  Hypertension, heart attacks, stroke, cardiomyopathy and myocarditis as well as irregular heart beats (arrhythmias) can develop. The brain is very sensitive to toxic effects of alcohol as well. This causes major depression, personality changes with violent behavior, car accidents and injuries.

Other toxic effects of alcohol on organs

Kidney disease (alcoholic nephropathy) is another illness due to too much alcohol. Five percent  of breast cancers in northern Europe and North America are a direct consequence to the toxic effects of alcohol (Ref.3). Finally, the liver being so active in detoxifying alcohol, will be not functioning and finally develops liver cirrhosis, as described before. This accounts for a lot of premature deaths at a relatively young age (typically in the mid to late 50’s).

Ref. 3 goes on to say that literature exists which claims that 1 to 2 drinks per day would be useful for prevention of heart disease. But the observation of the authors is that people will not discipline themselves to stick to these limits and very quickly enter into the zone of alcohol toxicity. The authors further noted that with regard to causing any kind of cancer there is no safe lower limit; the risk is directly proportional to the amount of alcohol consumed and the risk starts right above the zero point.

The pathologist has the last word

When I studied medicine at the University of Tübingen, Germany I attended lectures in the pathology department where Professor A. Bohle, M.D. demonstrated pathology findings of deceased patients. Dr. Bohle had a special interest in Mallory bodies. These are alcohol inclusion cysts within liver cells that can be stained with a bright red dye.

Histological documentation of toxic effects in livers of corpses

I will never forget when Prof. Bohle pointed out that the livers of this most diverse population, whose bodies we had the privilege as medical students to study, had a rate of 25% positive Mallory bodies. He wanted to impress on us as medical students to watch out for the alcoholics that are usually missed in general practice. Obviously 25% of the pathology population was affected by the consumption of alcohol. It was Prof. Bohle’s hope that we could perhaps interfere on the primary care level before things went out of control. Many of these corpses were the sad results of traffic accidents that could have been prevented. (In 2018 things have changed: seat belts and alcohol limits are standard, in 1968 in Germany they were not).

Alcohol as an aging substance

Consistent use of alcohol on a regular basis will slow down cell metabolism and hormone production significantly. The major effect of alcohol leads to poisoning of the mitochondria in multiple organs, which translates into faster aging and a shortened life expectancy. This in turn results in a change of appearance. An older person who has abused alcohol for a number of years may look 5 to 10 years older than their chronological age.

50% of people above the age of 65 drink daily (Ref.4). Some more statistics: alcohol abuse in elderly men is 4-times higher than in elderly women. 5% to 10% of all dementia cases are related to alcohol abuse. About 15% of older adults are experiencing health risks from abusing alcohol. And about 90% of older adults are using medications. Close to 100% of medications can adversely interact with alcohol (Ref.4).

Social pressure

These are the scientific facts, and then there is social pressure, when you are invited to a party.

When you are young and believe that you are invincible, do you care what the science says? You want to have a “good time” and not worry about consequences. The data about long-term exposure and a slowly increasing cancer risk is there. The wine industry will remind you that 1 drink for women and two drinks for men will protect you from heart attacks. They will withhold the cancer information from you, as they don’t really want to hear about that (yes, it’s bad for their business!).

Resisting social pressure and doing what is good for you

Can you have a good time at a party without drinking alcohol? Yes, you can. You can talk and you can listen; you are probably more with it than those who had too much to drink. I like mineral water and hold on to a glass of that.

I explained in a blog before how I was convinced by three speakers at an A4M conference to join those who abstain from alcohol.

Socializing without alcohol is doable. You may at times miss it, but you can warm up even to a crowd that had a few drinks too much. It is about choice: we can choose what we want out of life.

 

Dementia From Excessive Alcohol Abuse

Dementia From Excessive Alcohol Abuse

Conclusion

Alcohol is a cell and nerve poison. The medical need for “one glass of wine for women and two glasses of wine for men to prevent heart attacks and strokes” has been vastly exaggerated. Fact is that resveratrol and other antioxidants like vitamin C and vitamin E can also prevent cardiovascular disease. They are alcohol-free! The risk of dementia development as a long-term result of alcohol exposure is something that is only now getting attention by the medical profession. We live longer these days, and this makes alcohol exposure over the decades a real threat to our mental wellbeing. Consumption of alcohol needs to be re-evaluated by every one of us. What risks are we willing to take? Is the stress-relieving effect of alcohol worth the risk of losing our mind to Alzheimer’s disease? If we care about our future the answer should be clear!

What Alcohol Does To You

What Alcohol Does To You

Conclusion

I have attempted to show you the toxic effects of alcohol. Although alcohol has played an important role in the social lives of millions over the centuries, it is becoming more apparent that alcohol is a cell poison and shortens our lives. The beneficial effect of the 1 or 2 drinks marketed by the beer and wine industry and some cardiologists does nothing to counter the threat in terms of a whole array of cancers at much smaller amounts of alcohol. Fortunately, resveratrol and omega-3 fatty acids as supplements as well as exercise will more than make up for the 1 or 2 drinks that you do not really need. And neither exercise, omega-3 fatty acids, or resveratrol are cell poisons. The choice is yours!

Early Alcohol Use Will Result In Memory Loss Later In Life

Researchers found that heavy alcohol use in males during midlife paves the way to memory loss from dementia later in life.

I thought that this would be a good topic to review the effect of alcohol in general. Alcohol is a known cell poison, yet cardiologists keep on referring to the beneficial effects of that 1 glass of wine per day that will prolong your life. I will attempt to explain these diverse effects, where small amounts are supposed to be good for you while high amounts can be very damaging.

Review of the effects of alcohol

50% of the world population drinks alcohol, 10% to 20% have chronic alcoholism (Ref.1).  Just recently a Guardian news study was released showing that an astounding 25% of Russian men die before reaching the age of 55, compared to only 7% of men in the United kingdom and less than 1% of men in the US. The study looked at the effects of consuming large amounts of vodka.  There are about 10 million chronic alcoholics in the US. Chronic alcohol consumption leads to 100,000 deaths every year in the US. More than 50% of these deaths are from traffic accidents, the rest from medical problems caused by alcohol (Ref.1). Most of the alcohol gets detoxified through the liver cells and is metabolized into acetaldehyde. This involves the cytochrome P-450 system. That means that when a person also takes narcotics, sedatives or psychoactive drugs that are also metabolized through this liver enzyme system drugs and alcohol are taking much longer to be metabolized. This can lead to lethal overdoses that we hear about on TV all the time, hence the warning that you must not mix alcohol with drugs.

Early Alcohol Use Will Result In Memory Loss Later In Life

Early Alcohol Use Will Result In Memory Loss Later In Life

Alcohol is a cell and nerve poison. The most vulnerable organs in the body are the liver, brain, heart, pancreas, bone marrow and stomach. So, here are a number of conditions caused by drinking alcohol:

a)    Anemia: When a person drinks heavily and regularly anemia shows up in a blood test. Alcohol has a toxic effect on the bone marrow, which interferes with the production of red blood cells. But certain vitamins required by the bone marrow to manufacture red blood cells are often also missing in the diet of an alcoholic, which contributes to anemia as well.

b)    Cirrhosis of the liver develops in 10% to 20% of heavy drinkers. With cirrhosis part of the liver cells get replaced by fibrotic tissue and in advanced cases this can lead to a hepatic coma and death. Others are developing alcoholic hepatitis. This is an inflammation of the liver with fever and jaundice where the skin and eyeballs turn yellow. It is associated with severe abdominal pain.

c)    Gastritis: Alcoholic gastritis is common, but often undetected. The affected individual may just have stomach pains for a few days, or vomit food and/or blood in addition. With continued use of alcohol it may turn chronic. Alcoholic gastritis can turn into gastric ulcers with massive bleeding that often lead to death.

d)    Pancreatitis: The pancreas is a particularly vulnerable glandular tissue, which gets damaged by regular alcohol intake and with chronic alcohol intake gets partially replaced by fibrotic tissue causing the feared and painful chronic pancreatitis. This is a condition with vomiting and severe abdominal pains that can be unrelenting.

e)    High blood pressure, seizures, dementia, depression, heart irregularities and nerve damage:

You may ask yourself how all of these conditions would be reasonably under one heading. The heading for this is “nerve damage”. Let me explain: The sympathetic nerve is very sensitive to alcohol toxicity and when the sympathetic nerve fibers are damaged, you will develop high blood pressure. You see your physician, get blood pressure medication, but the pressure is difficult to control, if you continue to drink alcoholic beverages. It does not make sense to just add blood pressure pills and hope that this will cure your problem. Seizures are due to direct nerve damage in the more sensitive parts of the brain, which will cause these areas to produce extra electrical activities, which we call seizures. Again, just treating with anti-seizure medications is not the solution. Avoidance of alcohol is the other part of the treatment schedule. Dementia from heavy alcohol use is due to direct nerve atrophy in the brain. Our brain shrinks normally 1.9% to 2.8% per decade, depending on which research papers you read. But in the presence of heavy drinking the frontal lobe of the brain is particularly vulnerable to brain shrinkage.

As this publication shows, mild and moderate drinkers did not suffer more frontal lobe shrinkage than abstainers, but heavy drinkers had a 1.8-fold higher risk of frontal lobe shrinkage on average when compared to abstainers. It was calculated that alcohol had contributed 11.3% to that frontal lobe shrinkage.

The rest of the toxic effect on the nerve tissue explains why depression would develop. The frontal brain contains most of the serotonin producing nerve cells. When serotonin-producing nerve fibers get damaged, the body does not produce enough serotonin to prevent depression from setting in; GABA producing cells often also get damaged, which causes anxiety. It’s not good enough to just prescribe anxiolytic drugs to which the patient will get addicted. The whole person needs to be treated, and abstinence from alcohol has to be part of the program.

Heart irregularities (atrial fibrillation, ventricular fibrillation) can be life-threatening complications due to the toxic effect of alcohol on the nerve fibers within the heart muscle. Emergency physicians are aware of the connection of these conditions to alcohol consumption. Some people’s hearts are more sensitive to the effects of alcohol than others. The most common cause of temporary atrial fibrillation is excessive alcohol intake (holiday heart) according to Ref. 2.

Finally there is the effect of alcohol on nerves in the body. This explains that heavy alcohol consumers can come down with painful pins-and-needles sensations in their hands and feet or with numbness or loss of muscle strength. When the parasympathetic nervous system is affected embarrassing incontinence or constipation can result. Erectile dysfunction in men is also very common. Viagra and continuing to drink is not the solution.

f)      Gout: This painful formation of uric acid crystals in joints can be precipitated in sensitive individuals by consuming alcohol in combination with eating large helpings of beef. There may be a history of gout in the family. Treatment for this is to refrain from alcohol and avoid foods that are leading to uric acid production when ingested.

g)    Cancer: When the body detoxifies alcohol in the liver, the breakdown product is acetaldehyde, which is a known cancer producing substance. A whole array of cancers are known, which come from heavy, chronic alcohol consumption: cancers in the mouth, larynx, esophagus, stomach, pancreas, liver and colorectal cancer have all been linked to excessive alcohol intake.

h)    Cardiovascular disease: heart attacks and strokes can be caused particularly by binging; it is thought that binging makes platelets from the blood more sticky so they clump together and cause blood clots, which in turn leads to heart attacks and strokes.

i)      Infections: Alcohol weakens the immune system, which is another effect on the bone marrow similar to causing anemia, except that this is the toxic effect on the white blood cells and lymphocytes. Heavy alcohol consumers are more prone to pneumonia, to HIV, sexually transmitted diseases, and tuberculosis.

Cardiology view of preventative alcohol

Despite all of these hair raising toxic effects cardiologists have painted the rosy picture that 1 glass of wine for women and 2 glasses of wine for men per day will prevent heart disease. What is the true story here?

Ref.2 points out that there are about 100 prospective studies that confirm that there is an inverse relationship between mild to moderate alcohol consumption and “heart attack, ischemic stroke, peripheral vascular disease, sudden cardiac death, and death from all cardiovascular causes”. It describes further that the reduction of risk in these various studies was persistent and consisted of a 20% to 45% risk reduction. Using blood tests investigators have found that this is because of an increase of HDL cholesterol, reducing blood clotting, making platelets less sticky and reducing inflammation as evidenced by a reduction of the C-reactive protein. Further research has pinpointed that it is the phenols and resveratrol that are contained in alcoholic beverages that are responsible for the beneficial effects. The bad news is that three glasses of wine or more do the opposite, so does binge drinking. Unless you are extremely disciplined and never increase your allowed limit (1 drink for women, 2 drinks for men) you will CAUSE heart disease rather than PREVENT it (Ref.2). Some people have a family history of breast cancer or colon cancer and they should avoid alcohol altogether; also people coming from alcoholic families should avoid alcohol.

Conclusion

Where does this leave us with regard to prevention of heart attacks, strokes and hardening of the arteries in the legs (peripheral vascular disease)? If you are disciplined and stick to the limits, you could prevent 20% to 45% of cardiovascular risk. The brain study mentioned in the beginning of the blog would also confirm that there was no difference between dementia or brain shrinkage when mild to moderate drinkers were compared to abstainers over 10 years. What is not told by the wine industry is that the same effects that prevent cardiovascular disease in mild to moderate drinkers can also be achieved by natural means: exercising regularly will raise your protective HDL cholesterol; taking ginkgo biloba, flax seed and omega-3 fatty acids thins your blood and the platelets are getting less sticky; omega-3 reduces inflammation and resveratrol elongates telomeres making you live longer. At the A4M conference in Las Vegas in December 2011 there were three speakers who pointed out that even small amounts of alcohol will poison mitochondria of your cells and interfere with normal hormone action. This was enough to make me join those who abstain alcohol completely. One thing has not yet been investigated in long-term studies, namely how small effects of alcohol may affect the body over several decades and over an entire lifetime. Despite all the promises of interest groups that red wine is a trendy drink for those interested in heart health, the fundamental long-term studies are missing. What does a guy do with a healthy heart and a brain that is not functioning too well? I just do not want to be the guinea pig in that worldwide study.

Forget The Glass Of Red Wine For Good Health

We have been hearing for over 10 years that 1 glass of red wine per day for women and 2 glasses of red wine per day for men would be recommended in order to prevent a heart attack or a stroke. Now we are confronted with new research from Boston showing that even small amounts of alcohol are bad for you as alcohol is a carcinogen (=cancer producing substance). Misinformation like this occurs when science concentrates only on one angle of health, such as cardiovascular disease prevention and the other part of the equation, the cancer producing (carcinogenic) effect of alcohol, is disregarded.

In 1996 this Australian study followed 1236 men and 1569 women 60 years and over for more than 5 years and studied their mortality rates as a function of alcoholic drink intake. The authors found that there was a short-term protective effect with regard to cardiovascular/stroke mortality. But due to the fact that mortality was the end point for both cardiovascular disease and for cancer, the study was mostly taken as evidence that alcoholic beverages would protect to a certain degree from strokes and heart attacks. The authors were aware that alcohol was cancer causing as they stated, “Those taking any alcohol exhibited an increased proportion of deaths due to cancer at the expense of a reduced proportion of CHD and stroke deaths”. But this part was not mentioned in the popular press or in future alcohol/cardio-protective recommendations. The authors also were aware that the observation time of 5 years was on the short side. We know from other studies that alcohol toxicity requires a longer observation time such as 15 to 20 years or longer to show significance in a multitude of cancers.

Forget The Glass Of Red Wine For Good Health

Forget The Glass Of Red Wine For Good Health

As already mentioned above, recently a new survey of alcohol-caused cancer was published and went through the popular press. Dr. Timothy S. Naimi from Boston University Medical Center was the main investigator of an international team of scientists. The study found that every year 18,200 to 21,300 cancer deaths in the US (that is 3.2% to 3.7% of all US cancer deaths) are directly caused from alcohol consumption. The authors of the study determined that every person who dies from alcohol related causes lost on average approximately 18 years of his/her life (scientists call this “years of potential life lost”).  51% of women developed breast cancer from alcohol exposure, 62% of men came down with upper airway and esophageal cancers. Less than 1.5 drinks per day caused between 26% and 35% of alcohol-related cancer deaths. There was no safe lower margin. The authors concluded, “Reducing alcohol consumption is an important and underemphasized cancer prevention strategy”.

Interestingly, in 2006 other research looked at alcohol caused cancer cases in the world based on WHO data and came to the conclusion that with the increased worldwide consumption, particularly in East Asia, preventative steps by eliminating or replacing alcoholic drinks would be wise.

A recent study in 2012 where cancer rates in the US were compared between Hispanics and Caucasians showed that Hispanics had higher rates of stomach cancer, liver cancer, uterine/cervix cancer and gallbladder cancer. The authors concluded that Hispanics need more screening done such as Pap tests and that effective vaccines (like Gardasil) should be used. In addition effective interventions should be applied to reduce obesity, curtail alcohol consumption and reduce tobacco use.

Studies have shown that there is no safe level of alcohol consumption, not even the famous 1 drink for women and 2 drinks for men (with regard to heart attack prevention), because cancer incidence increases with increasing alcohol consumption in a linear relationship.

What does alcohol do in the body that it is so dangerous to your cells? Many cancer researchers have researched this question in detail. Essentially, alcohol is by itself a toxin for your cells (the targets being sub particles in your cells called microsomes and mitochondria). Your liver metabolizes alcohol into acetaldehyde, your kidneys excrete it and your lungs exhale it (this is how a breathalyzer can detect how much you have been drinking). All of these chemical changes in your cells release free radicals, which in turn attack other cells. This sets up a chronic inflammatory process, which breaks down your immune system, leads to cell mutations and finally to cancer.

What protects you from cancer?  It is the antioxidants that stabilize the above-mentioned processes: vitamin C, glutathione, vitamin D 3, curcumin, multiple vitamins, magnesium, flavonoid foods, cruciferous foods (like broccoli), exercise and soluble fiber.

So, if you were serious about cancer prevention, you may want to stop any alcohol intake and take the above supplements instead. The heart attack and stroke protection will be achieved by flavonoid foods (perhaps specifically adding resveratrol 250 mg per day as well) and exercise.

If you were less conscientious about cancer prevention, at least reduce your alcohol consumption perhaps to the occasional glass of wine or beer, but avoid high percentage spirits and remember, the less the better! You may be toasting to ill health with that glass of wine. Say no to false advertising of the wine industry! Your body will thank you for it.
