Alcoholism
Physical dependence on alcohol to the extent that stopping alcohol use will bring on withdrawal symptoms. In popular and therapeutic parlance, the term may also be used to refer to ingrained drinking habits that cause health or social problems. Treatment requires first ending the physical dependence, then making lifestyle changes that help the individual avoid relapse. In some cases, medication or hospitalization are needed. Alcohol dependence can have many serious effects on the brain, liver, and other organs of the body.

n.
the syndrome due to physical dependence on alcohol, such that sudden deprivation may cause withdrawal symptoms - tremor, anxiety, hallucinations, and delusions (see delirium tremens). The risk of alcoholism for an individual and its incidence in a society depend on the amount drunk. Countries such as France, where heavy drinking is socially acceptable, have the highest incidence. Usually several years' heavy drinking is needed for addiction to develop, but the range is from one to 40 years. Alcoholism impairs intellectual function, physical skills, memory, and judgment: social skills, such as conversation, are preserved until a late stage. Heavy consumption of alcohol also causes cardiomyopathy, peripheral neuritis, cirrhosis of the liver, and enteritis. Treatment is usually given in a psychiatric hospital, where the alcoholic is first 'dried out' and then helped to understand the psychological pressures that led to his heavy drinking. Drugs such as disulfiram (Antabuse), which cause vomiting if alcohol is taken, may help in treatment.
