People with alcohol dependence, the most severe alcohol disorder, usually experience tolerance and withdrawal. Tolerance is a need for markedly increased amounts of alcohol to achieve intoxication or the desired effect. Withdrawal occurs when alcohol is discontinued or intake is decreased. Alcohol dependents spend a great deal of time drinking alcohol, and obtaining it.

Alcohol abusers are "problem drinkers", that is, they may have legal problems, such as drinking and driving, or binge drinking (drinking 6 or more drinks on one occasion). People who are dependent on or abuse alcohol return to its use despite evidence of physical or psychological problems. Those with dependence have more severe problems and a greater compulsion to drink.

Alternative Names:
Alcohol dependence; Alcohol abuse
Causes, incidence, and risk factors:

Alcoholism is a type of drug addiction. There is both physical and psychological dependence with this addiction. Physical dependence reveals itself by withdrawal symptoms when alcohol intake is interrupted, tolerance to the effects of alcohol, and evidence of alcohol-associated illnesses.

Alcohol affects the central nervous system as a depressant, resulting in a decrease of activity, anxiety, tension, and inhibitions. Even a few drinks can result in behavioral changes, a slowing in motor performance, and a decrease in the ability to think clearly. Concentration and judgment become impaired. In excessive amounts, intoxication may result.

Alcohol also affects other body systems. Irritation of the gastrointestinal tract can occur with erosion of the lining of the esophagus and stomach causing nausea and vomiting, and possibly bleeding. Vitamins are not absorbed properly, which can lead to nutritional deficiencies with the long-term use of alcohol. Liver disease, called alcoholic hepatitis, may also develop and can progress to cirrhosis. The heart muscle may be affected. Sexual dysfunction may also occur, causing problems with erections in men and cessation of menstruation in women.
