Alcoholism

Alcoholism is a term with multiple and sometimes conflicting definitions. In common and historic usage, alcoholism refers to any condition that results in the continued consumption of alcoholic beverages despite the health problems and negative social consequences it causes. Medical definitions describe alcoholism as a disease which results in a persistent use of alcohol despite negative consequences. Alcoholism may also refer to a preoccupation with or compulsion toward the consumption of alcohol and/or an impaired ability to recognize the negative effects of excessive alcohol consumption. Although not all of these definitions specify current and on-going use of alcohol as a qualifier, some do, as well as remarking on the long-term effects of consistent, heavy alcohol use, including dependence and symptoms of withdrawal.

While the ingestion of alcohol is, by definition, necessary to develop alcoholism, the use of alcohol does not predict the development of alcoholism. The quantity, frequency and regularity of alcohol consumption required to develop alcoholism varies greatly from person to person. In addition, although the biological mechanisms underpinning alcoholism are uncertain, some risk factors, including social environment, emotional health and genetic predisposition, have been identified.

Definitions and terminology

The definitions of alcoholism and related terminology vary significantly between the medical community, treatment programs, and the general public.

Medical definitions

The Journal of the American Medical Association defines alcoholism as "a primary, chronic disease characterized by impaired control over drinking, preoccupation with the drug alcohol, use of alcohol despite adverse consequences, and distortions in thinking."[1]

The DSM-IV (the standard for diagnosis in psychiatry and psychology) defines alcohol abuse as repeated use despite recurrent adverse consequences.[2] It further defines alcohol dependence as alcohol abuse combined with tolerance, withdrawal, and an uncontrollable drive to drink.[2] (See DSM diagnosis below.)

According to the APA Dictionary of Psychology, alcoholism is the popular term for alcohol dependence.[2] Note that there is debate whether dependence in this use is physical (characterised by withdrawal), psychological (based on reinforcement), or both.

Terminology

Many terms are applied to a drinker's relationship with alcohol. Use, misuse, heavy use, abuse, addiction, and dependence are all common labels used to describe drinking habits, but the actual meaning of these words can vary greatly depending upon the context in which they are used. Even within the medical field, the definition can vary between areas of specialization. The introduction of politics and religion further muddles the issue.

Use refers to simple use of a substance. An individual who drinks any alcoholic beverage is using alcohol. Misuse, problem use, and heavy use do not have standard definitions, but suggest consumption of alcohol beyond the point where it causes physical, social, or moral harm to the drinker. The definitions of social and moral harm are highly subjective and therefore differ from individual to individual.

Within politics, abuse is often used to refer to the illegal use of any substance. Within the broad field of medicine, abuse sometimes refers to use of prescription medications in excess of the prescribed dosage, sometimes refers to use of a prescription drug without a prescription, and sometimes refers to use that results in long-term health problems. Within religion, abuse can refer to any use of a poorly regarded substance. The term is often avoided because it can cause confusion with audiences that do not necessarily share a single definition.

Remission is often used to refer to a state where an alcoholic is no longer showing symptoms of alcoholism. The American Psychiatric Association considers remission to be a condition where the physical and mental symptoms of alcoholism are no longer evident, regardless of whether or not the person is still drinking. They further subdivide those in remission into early or sustained, and partial or full. Some groups, most notably Alcoholics Anonymous[citation needed], do not recognize remission. Instead, these groups use the term recovery to describe those who have completely stopped consumption of alcohol and are addressing underlying emotional and social factors.

Etymology

The term "alcoholism" was first used in 1849 by the physician Magnus Huss to describe the systematic adverse effects of alcohol.[citation needed]

In the United States, use of the word "alcoholism" was largely popularized by the inception and growth of Alcoholics Anonymous in 1939. Although lacking a specific definition for alcoholism, AA's "Big Book" compares alcoholism to an allergy and an illness.[3]

A 1960 study by E. Morton Jellinek is considered the foundation of the modern disease theory of alcoholism.[4] Jellinek's definition restricted the use of the word "alcoholism" to those showing a particular natural history. The modern medical definition of alcoholism has been revised numerous times since then. The American Medical Association currently uses the word alcoholism to refer to a particular chronic primary disease.[citation needed] A minority within the medical field, notably Herbert Fingarette and Stanton Peele, argue against the existence of this disease. However, critics of the disease model acknowledge that the word "alcoholism" refers to a disease, and use the term "heavy drinking" when discussing the negative effects of alcohol consumption.

Epidemiology

Substance use disorders are a major public health problem facing many countries. "The most common substance of abuse/dependence in patients presenting for treatment is alcohol."[5] In the United Kingdom, the number of 'dependent drinkers' was calculated as over 2.8 million in 2001.[6] The World Health Organization estimates that about 140 million people throughout the world suffer from alcohol dependence.[7][8]

Within the medical community, there is broad consensus regarding alcoholism as a disease state. Outside the medical community, there is considerable debate regarding the Disease Theory of Alcoholism. Proponents argue that any structural or functional disorder having a predictable course, or progression, should be classified as a disease. Opponents cite the inability to pin down the behavioral issues to a physical cause as a reason for avoiding classification.

A 2002 study by the National Institute on Alcohol Abuse and Alcoholism surveyed a group of 4,422 adult alcoholics and found that after one year some were no longer alcoholics,[9] with the breakdown as follows:

  • 25% still dependent
  • 27.3% in partial remission (some symptoms persist)
  • 11.8% asymptomatic drinkers (consumption increases chances of relapse)
  • 35.9% fully recovered — made up of 17.7% low-risk drinkers plus 18.2% abstainers.

Identification and diagnosis

Multiple tools are available to those wishing to conduct screening for alcoholism. Identification of alcoholism may be difficult because there is no detectable physiologic difference between a person who drinks frequently and a person with the condition. Identification involves an objective assessment regarding the damage that imbibing alcohol does to the drinker's life compared to the subjective benefits the drinker perceives from consuming alcohol. While there are many cases where an alcoholic's life has been significantly and obviously damaged, there are always borderline cases that can be difficult to classify.

Addiction Medicine specialists have extensive training with respect to diagnosing and treating patients with alcoholism.

Screening

Several tools may be used to detect a loss of control of alcohol use. These tools are mostly self reports in questionnaire form. Another common theme is a score or tally that sums up the general severity of alcohol use.

  • The CAGE questionnaire, named for its four questions, is one such example that may be used to screen patients quickly in a doctor's office.

Two "yes" responses indicate that the respondent should be investigated further. The questionnaire asks the following questions:

  1. Have you ever felt you needed to Cut down on your drinking?
  2. Have people Annoyed you by criticizing your drinking?
  3. Have you ever felt Guilty about drinking?
  4. Have you ever felt you needed a drink first thing in the morning (Eye-opener) to steady your nerves or to get rid of a hangover?[10][11]
The CAGE questionnaire, among others, has been extensively validated for use in identifying alcoholism. It is not valid for diagnosis of other substance use disorders, although somewhat modified versions of the CAGE are frequently implemented for such a purpose.
