Alcoholism

Withdrawal develops because the brain has physically adapted to the presence of alcohol and cannot function adequately in the absence of the drug. Symptoms of withdrawal may include elevated temperature, increased blood pressure, rapid heart rate, restlessness, anxiety, psychosis, seizures, and rarely even death.

There is no known common cause of alcoholism. However, several factors may play a role in its development. A person who has an alcoholic parent is more likely to become an alcoholic than a person without alcoholism in the immediate family. Research suggests that certain genes may increase the risk of alcoholism but which genes or how they exert their influence is controversial. Psychological factors may include a need for relief of anxiety, ongoing depression, unresolved conflict within relationships, or low self-esteem. Social factors include availability of alcohol, social acceptance of the use of alcohol, peer pressure, and stressful lifestyles.

The incidence of alcohol intake and related problems is increasing. Data from many sources indicate that about 15% of the population in the United States are problem drinkers, and approximately 5% to 10% of male drinkers and 3% to 5% of female drinkers could be diagnosed as alcohol dependent (12.5million people).
