Alcohol dependence
Summary
Alcohol dependence is a previous (DSM-IV and ICD-10) psychiatric diagnosis in which an individual is physically or psychologically dependent upon alcohol (also chemically known as ethanol).
In 2013, it was reclassified as alcohol use disorder in DSM-5, which combined alcohol dependence and alcohol abuse into this diagnosis.
Alcohol abuse#Diagnosis and Alcoholism#Diagnosis
According to the DSM-IV criteria for alcohol dependence, at least three out of seven of the following criteria must be manifest during a 12-month period:
Tolerance
Withdrawal symptoms or clinically defined alcohol withdrawal syndrome
Use in larger amounts or for longer periods than intended
Persistent desire or unsuccessful efforts to cut down on alcohol use
Time is spent obtaining alcohol or recovering from effects
Social, occupational and recreational pursuits are given up or reduced because of alcohol use
Use is continued despite knowledge of alcohol-related harm (physical or psychological)
Because only 3 of the 7 DSM-IV criteria for alcohol dependence are required, not all patients meet the same criteria and therefore not all have the same symptoms and problems related to drinking. Not everyone with alcohol dependence, therefore, experiences physiological dependence. Alcohol dependence is differentiated from alcohol abuse by the presence of symptoms such as tolerance and withdrawal. Both alcohol dependence and alcohol abuse are sometimes referred to by the less specific term alcoholism. However, many definitions of alcoholism exist, and only some are compatible with alcohol abuse. There are two major differences between alcohol dependence and alcoholism as generally accepted by the medical community.
Alcohol dependence refers to an entity in which only alcohol is the involved addictive agent. Alcoholism refers to an entity in which alcohol or any cross-tolerant addictive agent is involved.
In alcohol dependence, reduction of alcohol, as defined within DSM-IV, can be attained by learning to control the use of alcohol.

Physical dependence
Physical dependence is a physical condition caused by chronic use of a tolerance-forming drug, in which abrupt or gradual drug withdrawal causes unpleasant physical symptoms. Physical dependence can develop from low-dose therapeutic use of certain medications such as benzodiazepines, opioids, antiepileptics and antidepressants, as well as the recreational misuse of drugs such as alcohol, opioids and benzodiazepines. The higher the dose used, the greater the duration of use, and the earlier age use began are predictive of worsened physical dependence and thus more severe withdrawal syndromes.
Long-term effects of alcohol
The long-term heavy consumption of alcohol (alcohol use disorder) can cause severe detrimental effects. Health effects associated with alcohol intake in large amounts include an increased risk of developing an alcohol use disorder, malnutrition, chronic pancreatitis, erectile dysfunction, heart failure, atrial fibrillation, gastritis, stomach ulcers, alcoholic liver disease, certain types of dementia, and several types of cancer. In addition, damage to the central nervous system and peripheral nervous system (e.
Alcohol (drug)
Alcohol, sometimes referred to by the chemical name ethanol, is a depressant drug that is the active ingredient in drinks such as beer, wine, and distilled spirits (hard liquor). It is one of the oldest and most commonly consumed recreational drugs, causing the characteristic effects of alcohol intoxication ("drunkenness"). Among other effects, alcohol produces happiness and euphoria, decreased anxiety, increased sociability, sedation, impairment of cognitive, memory, motor, and sensory function, and generalized depression of central nervous system (CNS) function.
