Alcohol abuse is a previous psychiatric diagnosis in which there is recurring harmful use of ethanol despite its negative consequences.[1] In 2013 it was reclassified as alcohol use disorder (alcoholism) along with alcohol dependence.[2] There are two types of alcohol abuse, those who have anti-social and pleasure-seeking tendencies, and those who are anxiety-ridden people who are able to go without drinking for long periods of time but are unable to control themselves once they start.[3] Binge drinking is another form of alcohol abuse. According to surveys, the heaviest drinkers are the United Kingdom's adolescents.[4] In 2013, 139,000 deaths globally were directly due to alcohol abuse[5] and an additional 384,000 to cirrhosis from excess alcohol consumption.[5]

Definitions

Results of the ISCD 2010 study ranking the levels of damage caused by drugs, in the opinion of drug-harm experts in the UK. When harm to self and others is summed, alcohol was the most harmful of all drugs considered, scoring 72%.

Alcohol abuse is a pattern of drinking that results in harm to one’s health, interpersonal relationships, or ability to work. According to Gelder, Mayou & Geddes (2005) alcohol abuse is linked with suicide. They state the risk of suicide is high in older men who have a history of drinking, as well as those suffering from depression. Certain manifestations of alcohol abuse include failure to fulfill responsibilities at work, school, or home; drinking in dangerous situations, including the operation of a motor vehicle; legal concerns associated with alcohol use; and continued drinking despite problems that are caused or worsened by drinking. Alcohol abuse can lead to alcohol dependence.[6] In the diagnosis manual DSM-5 alcohol abuse is combined with alcohol dependence to create one unified disorder, alcohol use disorder (AUD),[7] that includes a graded clinical severity from moderate to severe with at least 2 criteria to make diagnoses. For adolescents, the DSM-5 proposes that diagnoses meeting 2 or 3 criteria would be similar to alcohol abuse while meeting over 4 criteria would be equivalent to alcohol dependence when compared to the DSM-IV.

Alcohol abuse has both short-term and long-term risks. If a person drives while drunk or regularly consuming binge drink (more than five standard drinks in one drinking session), they are considered to have been involved in alcohol abuse. Short-term abuses of alcohol include, but are not limited to, violence, injuries, unprotected sexual activities and, additionally, social and financial problems.[8]

The older adult population (over 65 years) is frequently overlooked when discussing alcohol abuse. A smaller volume of consumed alcohol has a greater impact on the older adult than it does on a younger individual. As a result the American Geriatrics Society recommends for an older adult with no known risk factors less than one drink a day or fewer than two drinks per occasion regardless of gender,[9][10][11] this is less than current recommendations of maximum alcohol consumption per week, for adults noted to be nine drinks for a male and seven for a female.[12]

Binge drinking

In the USA, binge drinking is defined as consuming more than five units in men and four units in women. It increases chances for vandalism, fights, violent behaviours, injuries, drunk driving, trouble with police, negative health, social, economic, or legal consequences to occur.[13] Binge drinking is also associated with neurocognitive deficits of frontal lobe processing and impaired working memory as well as delayed auditory and verbal memory deficits.[13]

Binge drinking combined with the stress of returning to work is a contributing factor to Monday deaths from heart attacks.[14] The chances of becoming dependent are increased greatly in men who have 15 or more drinks each week or women who have 12 or more drinks each week. This is known as alcohol dependency.[15]

It is believed that one way to prevent binge drinking is to raise the legal drinking age.[16]

Signs and symptoms

Individuals with an alcohol use disorder will often complain of difficulty with interpersonal relationships, problems at work or school, and legal problems. Additionally, people may complain of irritability and insomnia. Alcohol abuse is also an important cause of chronic fatigue.[17]

Signs of alcohol abuse are related to alcohol's effects on organ systems. However, while these findings are often present, they are not necessary to make a diagnosis of alcohol abuse. Signs of alcohol abuse show its drastic effects on the central nervous system, including inebriation and poor judgment; chronic anxiety, irritability, and insomnia. Alcohol's effects on the liver include elevated liver function tests (classically AST is at least twice as high as ALT). Prolonged use leads to cirrhosis and liver failure. With cirrhosis, patients develop an inability to process hormones and toxins. The skin of a patient with alcoholic cirrhosis can feature cherry angiomas, palmar erythema and — in acute liver failure — jaundice and ascites. The derangements of the endocrine system lead to the enlargement of the male breasts. The inability to process toxins leads to liver disease, such as hepatic encephalopathy.

Alcohol abuse can result in brain damage which causes impairments in executive functioning such as impairments to working memory, visuospatial skills, and can cause an abnormal personality as well as affective disorders to develop.[18][19] Binge drinking is associated with individuals reporting fair to poor health compared to non-binge drinking individuals and which may progressively worsen over time. Alcohol also causes impairment in a person's critical thinking. A person's ability to reason in stressful situations is compromised, and they seem very inattentive to what is going on around them.[13] Social skills are significantly impaired in people suffering from alcoholism due to the neurotoxic effects of alcohol on the brain, especially the prefrontal cortex area of the brain. The social skills that are impaired by alcohol abuse include impairments in perceiving facial emotions, difficulty with perceiving vocal emotions and theory of mind deficits; the ability to understand humour is also impaired in alcohol abusers.[20] Adolescent binge drinkers are most sensitive to damaging neurocognitive functions especially executive functions and memory.[21] People who abuse alcohol are less likely to survive critical illness with a higher risk for having sepsis and were more likely to die during hospitalization.[22]

Violence

Alcohol abuse is significantly associated with suicide and violence. Alcohol is the most significant health concern in Native American communities because of very high rates of alcohol dependence and abuse; up to 80 percent of suicides and 60 percent of violent acts are a result of alcohol abuse in Native American communities.[23]

Alcohol misuse costs the United Kingdom's National Health Service £3 billion per year. The cost to employers is 6.4 billion pounds sterling per year. These figures do not include the crime and social problems associated with alcohol misuse. The number of women regularly drinking alcohol has almost caught up with men.[66]

Also, according to studies of present and former alcoholic drinkers in Canada, 20% of them are aware that their drinking has negatively impacted their lives in various vital areas including finances, work and relationships.[65]

In the United States, many people are arrested for drinking and driving. Also, people under the influence of alcohol commit a large portion of various violent crimes, including child abuse, homicide and suicide. In addition, people of minority groups are affected by alcohol-related problems disproportionately, with the exception of Asian Americans.[64]

Alcohol abuse is associated with many accidents, fights, driving offenses and unprotected sex. Alcohol is responsible in the world for 1.8 million deaths and results in disability in approximately 58.3 million people. Approximately 40 percent of the 58.3 million people disabled through alcohol abuse are disabled due to alcohol-related neuropsychiatric disorders.[31] In South Africa, where HIV infection is epidemic, alcohol abusers exposed themselves to double the risk of this infection. Moreover, problems caused by alcohol abuse in Ireland cost about 3.7 billion euro in 2007.[63] Additionally, alcohol abuse increases the risk of individuals either experiencing or perpetrating sexual violence.[43]

Societal and economic costs

The introduction of alcopops, sweet and pleasantly flavoured alcoholic drinks, was responsible for half of the increase in alcohol abuse in 15-16-year-olds, according to one survey in Sweden. In the case of girls, the alcopops, which disguise the taste of alcohol, were responsible for two thirds of the increase. The introduction of alcopops to Sweden was a result of Sweden joining the European Union and adopting the entire European Union law.[61] Alcohol abuse is highly associated with adolescent suicide. Adolescents who abuse alcohol are 17 times more likely to commit suicide than adolescents who don't drink.[62]

Society and culture

College/university students who are heavy binge drinkers (three or more times in the past two weeks) are 19 times more likely to be diagnosed with alcohol dependence, and 13 times more likely to be diagnosed with alcohol abuse compared to non-heavy episodic drinkers, though the direction of causality remains unclear. Occasional binge drinkers (one or two times in past two weeks), were found to be four times more likely to be diagnosed with alcohol abuse or dependence compared to non-heavy episodic drinkers.[13]

Alcohol use disorders often cause a wide range of cognitive impairments that result in significant impairment of the effected individual. If alcohol-induced neurotoxicity has occurred a period of abstinence for on average a year is required for the cognitive deficits of alcohol abuse to reverse.[60]

Alcohol abuse during adolescence, especially early adolescence (i.e. before age 15), may lead to long-term changes in the brain which leaves them at increased risk of alcoholism in later years; genetic factors also influence age of onset of alcohol abuse and risk of alcoholism.[57] For example, about 40 percent of those who begin drinking alcohol before age 15 develop alcohol dependence in later life, whereas only 10 percent of those who did not begin drinking until 20 years or older developed an alcohol problem in later life.[58] It is not entirely clear whether this association is causal, and some researchers have been known to disagree with this view.[59]

Prognosis

Causes of alcohol abuse are complex and are likely the combination of many factors, from coping with stress to childhood development. The US Department of Health & Human Services identifies several factors influencing adolescent alcohol use, such as risk-taking, expectancies, sensitivity and tolerance, personality and psychiatric comorbidity, hereditary factors, and environmental aspects.[52] Studies show that child maltreatment such as neglect, physical, and/or sexual abuse,[47] as well as having parents with alcohol abuse problems,[53] increases the likelihood of that child developing alcohol use disorders later in life. According to Shin, Edwards, Heeren, & Amodeo (2009), underage drinking is more prevalent among teens that experienced multiple types of childhood maltreatment regardless of parental alcohol abuse, putting them at a greater risk for alcohol use disorders.[54] Genetic and environmental factors play a role in the development of alcohol use disorders, depending on age. The influence of genetic risk factors in developing alcohol use disorders increase with age[55] ranging from 28% in adolescence and 58% in adults.[56]

Alcohol abuse is said to be most common in people aged between 15 and 24 years, according to Moreira 2009.[31] However, this particular study of 7275 college students in England collected no comparative data from other age groups or countries.

Epidemiology

Mindfulness-based intervention programs (that encourage people to be aware of their own experiences in the present moment and of emotions that arise from thoughts) can reduce the consumption of alcohol.[50][51]

Some people who abuse alcohol may be able to reduce the amount they drink, also called "drinking in moderation." If this method does not work, the person may need to try abstinence.

Youth treatment and intervention should focus on eliminating or reducing the effects of adverse childhood experiences, like childhood maltreatment, since these are common risk factors contributing to the early development of alcohol abuse.[47] Approaches like contingency management and motivational interviewing have shown to be effective means of treating substance abuse in impulsive adolescents by focusing on positive rewards and redirecting them towards healthier goals.[48] Educating youth about what is considered heavy drinking along with helping them focus on their own drinking behaviors has been shown to effectively change their perceptions of drinking and could potentially help them to avoid alcohol abuse.[49] Completely stopping the use of alcohol, or "abstinence," is the ideal goal of treatment. A strong social network and family support maybe important in achieving this goal.

Treatment

An individual's need for alcohol can depend on their family's alcohol use history. For instance, if it is discovered that their family history with alcohol has a strong pattern, there might be a need for education to be set in place to reduce the likelihood of reoccurrence (Powers, 2007).[46] However, studies have established that those with alcohol abuse tend to have family members who try to provide help. In many of these occasions the family members would try to help the individual to change or to help improve the individual's lifestyle.

Withdrawal of alcohol leads to over-activity of neural function because the use of alcohol leads to the depression of the central nervous system. This results in hallucinations and seizures (Schreiber, 2001).[45]

According to European law, individuals who are suffering from alcohol abuse or other related problems cannot be given a license, or if in possession of a license cannot get it renewed. This is a way to prevent individuals driving under the influence of alcohol, but does not prevent alcohol abuse per se.[44]

Preventing or reducing the harm has been called for via increased taxation of alcohol, stricter regulation of alcohol advertising and the provision of brief Interventions. Brief Interventions for alcohol abuse reduce the incidence of unsafe sex, sexual violence, unplanned pregnancy and, likely, STD transmission.[43] Information and education on social norms and the harms associated with alcohol abuse delivered via the internet or face-to-face has been found to result in a decrease in harmful drinking behaviours in young people.[31]

The United States Navy provides informative, in-depth training on alcohol and drug abuse prevention to soldiers and supervisors.

Prevention

The CAGE questionnaire may be used to screen for alcohol misuse. The CAGE questionnaire consists of four questions: "Have you ever felt the need to cut down on drinking?", "Have you ever felt annoyed by criticism of drinking?", "Have you ever felt guilty about drinking?", and "Have you ever taken a drink first thing in the morning as an eye opener?".[42] If two or more of the questions are positive, alcohol abuse is considered.

Diagnosis

The brain goes through dynamic changes during adolescence as a result of advancing pubertal maturation, and alcohol can damage long- and short-term growth processes in teenagers.[41] The rapid effect of drugs releases the neurotransmitter dopamine which acts as reinforcement for the behavior.[3]

Until recently, the underlying mechanisms mediating the link between pubertal maturation and increased alcohol use in adolescence was poorly understood. Now research has suggested that sex steroid hormone levels may play a role in this interaction. When controlling for age, it was demonstrated that elevated estradiol and testosterone levels in male teenagers undergoing pubertal development was linked to increased alcohol consumption.[39] It has been suggested that sex hormones promote alcohol consumption behaviors in teens by stimulating areas in the male adolescent brain associated with reward processing. The same associations with hormone levels were not demonstrated in females undergoing pubertal development. It is hypothesized that sex steroid hormones, such as testosterone and estradiol, are stimulating areas in the male brain that function to promote sensation-seeking and status-seeking behaviors and result in increased alcohol usage.[39] Additionally, the enzyme TTTan aromatase, which functions in the male brain to convert testosterone to estradiols, has been linked to addictive and reward-seeking behaviors. Therefore, the increased activity of the enzyme may be influencing male adolescent alcohol-usage behaviors during pubertal development.[40] The underlying mechanisms for female alcohol consumption and abuse is still under examination, but is believed to be largely influenced by morphological, rather than hormonal, changes during puberty as well as the presence of deviant peer groups.[36]

Excessive alcohol use causes neuroinflammation and leads to myelin disruptions and white matter loss. The developing adolescent brain is at increased risk of brain damage and other long-lasting alterations to the brain.[38] Adolescents with an alcohol use disorder damage the hippocampal, prefrontal cortex, and temporal lobes.[29]

Mechanisms

Gender differences may affect drinking patterns and the risk for developing alcohol use disorders.[35] Sensation-seeking behaviors have been previously shown to be associated with advanced pubertal maturation, as well as the company of deviant peers.[28] Early pubertal maturation, as indicated by advanced morphological and hormonal development, has been linked to increased alcohol usage in both male and female individuals.[36] Additionally, when controlling for age, this association between advanced development and alcohol use still held true.[37]

Puberty

The numbing effects of alcohol and narcotics can become a coping strategy for traumatized people who are unable to dissociate themselves from the trauma. However, the altered or intoxicated state of the abuser prevents the full consciousness necessary for healing.[34]

A person misusing alcohol maybe doing so because they find alcohol's effects provide relief from a psychological problem, such as anxiety or depression. Often both the alcohol misuse and psychological problems need to be treated at the same time.

Mental illness

The cause of alcohol abuse is complex. Alcohol abuse is related to economic and biological origins and is associated with adverse health consequences.[4] Peer pressure influences individuals to abuse alcohol; however, most of the influence of peers is due to inaccurate perceptions of the risks of alcohol abuse.[31] According to Gelder, Mayou and Geddes (2005) easy accessibility of alcohol is one of the reasons people engage in alcohol abuse as this substance is easily obtained in shops. Another influencing factor among adolescents and college students are the perceptions of social norms for drinking; people will often drink more to keep up with their peers, as they believe their peers drink more than they actually do. They might also expect to drink more given the context (e.g. sporting event, fraternity party, etc.).[32] This perception of norms results in higher alcohol consumption than is normal. Alcohol abuse is also associated with acculturation, because social and cultural factors such as an ethnic group’s norms and attitudes can influence alcohol abuse.[33]

Causes

Alcohol abuse during adolescence greatly increases the risk of developing an alcohol use disorder in adulthood due to changes to neurocircuitry that alcohol abuse causes in the vulnerable adolescent brain.[29] Younger ages of initial consumption among males in recent studies has shown to be associated with increased rates of alcohol abuse within the general population.[30]

Adolescence and the onset of puberty have both a physiological and social impact on a developing person. About half of grade 12 students have been drunk, and a third binge drink. About 3% drink every day.[27] One of these social impacts is the increase in risk-taking behaviors, such as the emergence of alcohol use.[28] Children aged 16 and under who consume alcohol heavily display symptoms of conduct disorder. Its symptoms include troublesome behaviour in school, constantly lying, learning disabilities and social impairments.[4]
