SOC 204 Goldberg Ch 6 Week 3
This document discusses alcohol, including its pharmacology, effects on the brain and body, alcoholism, and impacts of alcohol use. Key points include: - Alcohol is metabolized in the liver and its effects include impaired judgment, reasoning, and motor skills as it acts on the cerebrum and limbic system. - Alcoholism is considered by some to be a disease, and is influenced by genetics, environment, and psychosocial factors. Withdrawal can cause severe symptoms. - Heavy alcohol use is associated with increased risks of accidents, violence, and health issues like liver disease and cancer, while moderate use may provide some heart benefits.

Editor's Notes
- #3 Fermentation = the production of alcohol from sugars through the action of yeasts Forms the basis of all alcoholic beverages Fruits + yeast = fermentation will begin Fruits naturally contain sugar Cereal grains contain starch, which must be converted to sugar by malt before fermentation can begin Yeast has a limited tolerance for alcohol When the concentration reaches a certain percentage (15% is possible, but standard for wine is about 12%) the yeast dies and fermentation ceases. Distillation = evaporation and condensing of alcohol vapors to produce beverages with alcohol content higher than 15 percent Perhaps first used in Arabia around AD 800 Introduced into Europe in about the 10th century In U.S., began on a large scale at the end of the 18th century Grain neutral spirits—clear, tasteless, nearly pure alcohol (190 proof) produced by distillation May be sold as Everclear or used in research Ethanol is used in commercial products as a gasoline additive, cleaner, solvent Used to make various beverages Gin: distillate filtered through juniper berries and then diluted with water Vodka: mixture of grain neutral spirits and water Contains relatively few congeners Whiskey = distillate of fermented malted barley Early U.S. distiller from Bourbon County, KY, gave beverage its name Distilled at a lower proof (160) and so contains more congeners and some flavor from the grain used Rye whiskey, corn whiskey (bourbon), blended whiskey Usually aged for at least two years Liqueurs or cordials Alcohol content 20 to 25 percent Originally made from brandy mixed with flavorings from herbs, berries, or nuts Now typically made from flavored, diluted grain neutral spirits Proof = alcohol content of a distilled beverage; twice the percentage of alcohol by weight 90-proof whiskey is 45 percent alcohol Beer Made by adding barley malt to other cereal grains Hops are added with yeast to give beer its distinctive flavor Lager—uses a type of yeast that settles to the bottom of the mash to ferment Most common type in United States Ale—uses a top-fermentation yeast, warmer fermentation temperature, more malt and hops Light beer—fermented longer at a cooler temperature More sugar is converted to alcohol, then water added Result is a beverage with similar alcohol content but less sugar (and fewer calories) than regular beer Most beer sold in the United States is mass-produced by the two largest brewers Imported beers and microbreweries are growing in popularity WINE Made from fermented grapes Produced by both small and large wineries Most wines contain about 12% alcohol Factors in quality include selection and cultivation of grapevines, good weather, timing of harvest, and careful monitoring of fermentation and aging Generics vs. varietals Determined by type of grapes and flavor Red vs. white Sweet vs. dry Sparkling wines Fortified wines Alcohol content near 20 percent
- #4 Absorption Some absorbed in the stomach, most in the small intestine Absorption is slower if there is food or water in the stomach Absorption is faster in the presence of carbonated beverages Factors that affect rate of absorption: Food in the stomach slows absorption Wine and beer absorbed slower than distilled spirits Carbonation increases absorption Strong emotions increase absorption Males absorb alcohols slowly and break it down quickly Women absorbs alcohol more quickly during the premenstrual phase Women who take birth control pills absorb alcohol more quickly Distribution Blood alcohol concentration (BAC) is a measure of the concentration of alcohol in blood, expressed as a percentage in terms of grams per 100 ml Alcohol is distributed throughout body fluids Alcohol is less distributed in fatty tissues, so a lean person will have a lower BAC than a fatter person of the same weight Metabolism: Liver metabolizes about 0.25 ounces of alcohol per hour If rate of intake = rate of metabolism, BAC is stable If rate of intake exceeds rate of metabolism, BAC climbs Standard drink has about 0.5 ounces of pure alcohol 12 ounces of beer 4 ounces of wine 1 ounce of 100-proof spirits Women tend to be more susceptible than men to the effects of alcohol after consuming the same amount Alcohol dehydrogenase (a stomach enzyme) is more active in men Women absorb a greater proportion of the alcohol they drink Women tend to weigh less and have a higher proportion of body fat “Tank” into which alcohol is added is smaller About 2 percent of alcohol is excreted unchanged About 90 percent is metabolized in the liver Exercise, coffee, and other strategies do not speed up the rate of metabolism Liver responds to chronic intake of alcohol by increasing enzyme activity Contributes to tolerance among heavy users Can result in cross-tolerance to other depressants MECHANISM OF ACTION Central nervous system depressant Used as anesthetic until the late 19th century Alcohol has many effects on the brain and the mechanisms are difficult to pin down Similar to barbiturates and benzodiazepines, it enhances the inhibitory effect of GABA at the GABA-A receptor At high doses, it blocks the effects of the excitatory transmitter glutamate It affects dopamine, serotonin, and acetylcholine neurons Alcohol in the body is transformed by the liver into acetaldehyde, then further broken down into acetate, then water and carbon dioxide Alcohol leaves the body at a rate of about 3/4 ounce per hour One ounce of distilled spirits, a bottle of beer, and a glass of wine all have about the same amount of alcohol Blood alcohol concentration (BAC): Percentage of alcohol in the bloodstream Rises when alcohol is consumed at a rate exceeding the rate at which it is metabolized or leaves the body As BAC increases, behavioral and subjective effects become more pronounced Drinking too much alcohol in a short time can be fatal
- #7 15% to 30% of nursing home patients are admitted because of permanent alcohol-induced brain damage Five to six drinks daily adversely affects cognitive functioning Time out from day-to-day expectations Driving under the influence Sexual behavior Blackouts Blood alcohol concentration determines effects At low effective blood levels: complex and abstract behaviors disrupted At higher blood levels: simpler behaviors also affected Mood changes can include euphoria, reduced anxieties, and reduced inhibitions Effects are greater when BAC is rising A higher BAC is needed to impair a chronic heavy drinker Expectations (placebo effects) explain many of the effects on social behavior Alcohol use serves as a social signal for a time-out from responsibilities, work, and seriousness Intoxicated individuals focus on the here and now, with little care for future consequences (alcohol myopia) DRIVING UNDER INFLUENCE Less than 40 percent of all traffic crash fatalities are linked to alcohol use Risk of a fatal crash is dose-related Single-vehicle fatalities are more likely to involve alcohol than are multiple-vehicle fatalities Alcohol-related fatalities are more likely to occur during dark hours and on weekends Men are more likely than women to be involved in an alcohol-related fatal crash Anyone who drinks and drives (not just problem drinkers) is a potential threat Current efforts Keep repeat offenders off the road Publicize the dangers of drinking and driving Target younger drinkers for special prevention efforts Sexual behavior Alcohol use enhances interest in sex but impairs physiological arousal Linked to unsafe sex Blackouts A danger sign of excessive alcohol use Crime and violence—alcohol use is statistically related to violence Homicide Assault, including family violence, sexual assault, and date rape Suicide Peripheral circulation: Dilation of peripheral blood vessels means that drinkers lose body heat but feel warm Fluid balance: Alcohol has a diuretic effect that can lower blood pressure in some people Hormonal effects: Chronic abusers of alcohol can develop a variety of hormone-related disorders Crime and violence Physiological Effects
- #11 An alcoholic is a problem drinker, but a problem drinker is not necessarily an alcoholic Alcoholics are dependent on alcohol – a problem drinker has interpersonal, financial, or social problems from drinking The problem drinker may drink infrequently, but has problems when consuming alcohol A common symptom of problem drinking is blackouts, characterized by temporary memory loss Common elements of alcoholism Alcoholics are unable to control their drinking Some physical, social, or psychological consequence will result from their drinking

- #32 HISTORY Alcoholic beverages have been consumed for thousands of years, at least as far back as 6400 BC (beer and berry wine) Grape wine has existed for over 2,000 years Mead may date back to the Paleolithic Age, around 8000 BC Beer was consumed by Native Americans at the time of Columbus’s landing Before American Revolution People drank more alcohol than water Drunkenness was viewed as misuse of positive product After American Revolution Alcohol itself viewed as the cause of serious problems, an active agent of evil Alcohol was first psychoactive substance to become demonized in American culture Benjamin Rush (1745-1813) Heavy drinking = health problems Alcohol use damages morality Alcohol addiction = a disease Temperance societies Initially promoted abstinence from distilled spirits and moderate consumption of beer and wine Later promoted total abstinence Became fashionable to “take the pledge” (see right) States began passing prohibition laws in 1851 By 1917, 64 percent of Americans lived in “dry” territory Laws reflected issues of class, ethnicity, religion, immigration, and politics People still drank illegally in speakeasies and private clubs and legally through purchase of patent medicines Federal prohibition 18th Amendment to the U.S. Constitution, banning the sale of alcohol, was ratified in January 1919 National prohibition went into effect in January 1920 People continued to buy and sell alcohol illegally, and enforcement was challenging and expensive Organized crime became more organized and profitable Alcohol dependence and alcohol-related deaths declined REPEALED Concerns that widespread disrespect for Prohibition laws encouraged a general sense of lawlessness Taxation: Alcohol taxes had been a major source of revenue Repealed by the 21st Amendment Ratified in 1933 Alcohol per capita sales and consumption increased slowly until after World War II, when they returned to pre-Prohibition levels Regulation after 1933 Some states remained dry after national prohibition ended, but most allowed at least beer sales Laws were slowly relaxed until the last dry state, Mississippi, became wet in 1966 Drinking ages were lowered in some states but raised again to 21 following concerns over increased drinking rates and alcohol-related traffic accidents Taxation Federal and state taxes and licensing fees = about half the price of an alcoholic beverage When taxes go up, consumption goes down, but not dramatically Colonial Times: Pilgrims anchored at Plymouth because their supply of beer and spirits was becoming depleted Attitudes of early settlers toward alcohol were positive Two important factors: sanitation and nutrition 1640: Dutch opened the first distillery on Staten Island Rum trade was New England’s most profitable business Consumption peaked during Jefferson’s presidency 1784: Dr. Benjamin Rush described harmful effects Early 1800s: movement to curb the escalating rate of alcohol use and abuse Alcohol was seen as a major cause of crime and violence Temperance movement sought to modify alcohol use, not to eliminate it 1808: independent organizations formed temperance groups 1826: American Society for the Promotion of Temperance 1830 to 1840, annual per capita use of alcohol declined from about 7 gallons per adult to about 3 gallons Following the Civil War, the temperance movement became strong again Three influential groups in alcohol reform: Women’s Christian Temperance Union (WCTU) Anti-Saloon League National Prohibition Party 1880 to 1889: 7 states passed prohibition laws 1907 to 1919: 34 states passed similar legislation 1920: U.S. Senate adopted the 18th Amendment (Volstead Act) which prohibited the manufacturing and sale of alcohol Problems: Illegal trade of alcohol Organized crime Enforcement problems Toxic adulterants in black market alcohol Home brewing was not illegal
- #33 Regional differences in the United States Stress index: Drinking rates higher in states where people experience a great deal of social stress and tension Drinking norms: Drinking rates higher in states where people tend to approve of the use of alcohol to relieve stress Gender differences: Males more likely to drink than females, and more likely to drink more Women’s drinking patterns: Women who are unemployed, looking for work, or employed part-time outside the home Women who are divorced, separated, or not married but living with a partner Heavy drinking after a health problem such as depression or reproductive difficulties Drinking among college students College students drink more than their nonstudent peers Many campuses have banned sale and advertising of alcohol, and many fraternities have banned keg parties Alcohol use and drinking behavior hasn’t changed significantly in response Today’s college students are less likely to drink and drive compared to students in the early 1980s Student drinking patterns: Australia: almost one-half of students drank to harmful or hazardous levels Germany: 80% of university students drank heavily and 20% displayed problem drinking 37% of college students binge drink 44% reported being drunk within the past 30 days Binge drinking: Consuming five or more drinks (men) or four (women) in a short period of time Typically starts at an early age and increases during adolescence Motivations change as people age Influenced by the perception of others’ use of alcohol The highest rate of alcohol consumption is in the West while the lowest rate of consumption is in the South Abstinence is increasing for men and women Rates of abstinence and heavy drinking are greater in rural areas The proportion of heavy drinkers in their 20s has increased slightly, along with problems related to alcohol dependency Variables correlated with drinking patterns: College students who are fraternity and sorority members have higher alcohol consumption rates Gay men and lesbians are more likely to drink heavily Binge drinking is more common in households with an annual income above $75,000 Adolescents who are victims of bullying are more likely to drink as a coping mechanism European adolescents living in rural areas binge drink more than urban adolescents People who engage in binge eating are more likely to engage in binge drinking Drinking patterns by ethnicity: Whites begin drinking at an earlier age than Blacks and Hispanics, and progress faster to alcohol dependence Alcohol-related mortality is greater for Black and Hispanic men than for White and Asian American men Mexican Americans had more alcohol-related problems than those of Puerto Rican or Cuban origin Drinking patterns are affected by acculturation Asian students resist social pressure to drink alcohol better than Caucasians Native Americans have the highest rates of alcohol-related deaths of all ethnicities in the US
- #34 Cultural influences on drinking—ethnic and social factors Trends in U.S. alcohol consumption Use peaked in 1981, followed by a decline, mirroring patterns of illicit drug use Decline particularly significant for distilled spirits About one-third of Americans abstain Average consumption among drinkers = about 3 drinks per day—but most drink far less Half of all alcohol consumed in the United States is consumed by about 10 percent of the drinkers Regional differences in the United States Stress index: Drinking rates higher in states where people experience a great deal of social stress and tension Drinking norms: Drinking rates higher in states where people tend to approve of the use of alcohol to relieve stress Most people who drink today are social drinkers who are able to abstain from alcohol at will People who cannot abstain and develop medical and social difficulties are called problem drinkers or alcoholics A person can abuse alcohol and not be an alcoholic Alcohol is a legal drug Leads to belief that effects are not negative or severe Belief that, if alcohol were bad, the government would limit its availability Parents and other role models consume alcohol as part of their lifestyle As costs increase, consumption levels decrease An increase in taxes on alcohol appears to reduce consumption, especially among underage drinkers A decline in alcohol drinking since the early 1980s has been reflected largely in less use of distilled spirits such as whiskey, vodka, gin, and rum
- #39 The definition of moderate drinking for men is no more than two alcoholic drinks per day – for women, no more than one alcoholic drink per day There is no standard definition of heavy drinking Binge drinking is consumption of five or more drinks at one sitting for men and four or more drinks for women
- #40 Alcohol overdose (poisoning) is common and dangerous If someone drinks enough to pass out Place her or him on side and monitor breathing or take to ER immediately Do not leave the person alone If someone drinks enough to vomit He or she should stop drinking Vomiting reflex indicates a rapidly rising BAC but is suppressed at BACs above 0.20 percent HANGOVER Symptoms: upset stomach, fatigue, headache, thirst, depression, anxiety, and general malaise Possible causes: alcohol withdrawal, exposure to congeners, cellular dehydration, gastric irritation, reduced blood sugar, and/or the accumulation of acetaldehyde Moderate drinking is the only way to avoid a hangover LONG TERM RISKS Brain tissue loss and intellectual impairment Liver disease: hepatitis, fatty liver, cirrhosis (see right) Heart disease: cardiomyopathy, heart attack, hypertension, stroke Alcohol’s effects on HDL may reduce heart attack risk among moderate drinkers Cancer Impaired immunity
- #42 FAS = a collection of physical and behavioral abnormalities caused by the presence of alcohol during fetal development Diagnostic criteria Growth retardation before and/or after birth Pattern of abnormal features of the face and head Evidence of central nervous system abnormality Fetal alcohol spectrum disorders (FASD): Various effects that occur as a result of women who drink alcohol while pregnant Effects can be behavioral, physical, and/or mental Leading known cause of mental retardation Fetus is especially vulnerable during the first trimester of pregnancy Smaller brain at birth, head and facial anomalies, retarded growth, central nervous system problems, and malformations of major organs, eye problems
- #45 Alcohol use is associated with neurotic and psychotic symptoms from depressive reactions to generalized anxiety disorders and panic attacks Wernicke-Korsakoff syndrome is a brain disorder due to thiamine (vitamin B1) deficiency. Causes Wernicke encephalopathy and Korsakoff syndrome are different conditions. Both are due to brain damage caused by a lack of vitamin B1. Lack of vitamin B1 is common in people with alcoholism. It is also common in persons whose bodies do not absorb food properly (malabsorption), as sometimes occurs with a chronic illness or after obesity (bariatric) surgery. Korsakoff syndrome, or Korsakoff psychosis, tends to develop as Wernicke symptoms go away. Wernicke encephalopathy causes brain damage in lower parts of the brain called the thalamus and hypothalamus. Korsakoff psychosis results from permanent damage to areas of the brain involved with memory. Symptoms Symptoms of Wernicke encephalopathy include: Confusion and loss of mental activity that can progress to coma and death Loss of muscle coordination (ataxia) that can cause leg tremor Vision changes such as abnormal eye movements (back and forth movements called nystagmus), double vision, eyelid drooping Alcohol withdrawal Symptoms of Korsakoff syndrome: Inability to form new memories Loss of memory, can be severe Making up stories (confabulation) Seeing or hearing things that are not really there (hallucinations) Exams and Tests Examination of the nervous/muscular system may show damage to many nerve systems: Abnormal eye movement Decreased or abnormal reflexes Fast pulse (heart rate) Low blood pressure Low body temperature Muscle weakness and atrophy (loss of tissue mass) Problems with walk (gait) and coordination The person may appear poorly nourished. The following tests are used to check a person's nutrition level: Serum albumin (relates to person's general nutrition) Serum vitamin B1 levels Transketolase activity in red blood cells (reduced in people with thiamine deficiency) Liver enzymes may be high in people with a history of long-term alcohol abuse. Other conditions that may cause vitamin B1 deficiency include: AIDS Cancers that have spread throughout the body Extreme nausea and vomiting during pregnancy (hyperemesis gravidarum) Heart failure (when treated with long-term diuretic therapy) Long periods of intravenous (IV) therapy without receiving thiamine supplements Long-term dialysis Very high thyroid hormone levels (thyrotoxicosis) A brain MRI may show changes in the tissue of the brain. But if Wernicke-Korsakoff syndrome is suspected, treatment should start immediately. Usually a brain MRI exam is not needed. Treatment The goals of treatment are to control symptoms and to prevent the disorder from getting worse. Some people may need to stay in the hospital early in the condition to help control symptoms. Monitoring and special care may be needed if the person is: Comatose Lethargic Unconscious Vitamin B1 may be given by injection into a vein or a muscle, or by mouth. It may improve symptoms of: Confusion or delirium Difficulties with vision and eye movement Lack of muscle coordination Vitamin B1 usually does not improve loss of memory and intellect that occur with Korsakoff psychosis. Stopping alcohol use can prevent more loss of brain function and damage to nerves. Eating a well-balanced, nourishing diet can help, but it is not a substitute for stopping alcohol use. Outlook (Prognosis) Without treatment, Wernicke-Korsakoff syndrome gets steadily worse, and can be life-threatening. With treatment, it is possible to control symptoms (such as uncoordinated movement and vision difficulties). This disorder can also be slowed or stopped. Some symptoms, especially the loss of memory and thinking skills, may be permanent. Other disorders related to alcohol use may also occur. http://www.nlm.nih.gov/medlineplus/ency/article/000771.htm
