Alcohol misuse

Definition

Alcohol misuse, abuse or alcoholism are catch-all terms for use of alcohol despite negative consequences. Alcohol dependence is specifically defined as physical dependence on alcohol.

Epidemiology

The prevalence of alcohol dependence is 5% in England and Wales (8% men, 2% women). As of 2001, 27% of men and 15% of women over 16 drunk more than their weekly recommended limit. The same is true for 39% of men's and 22% of women's daily limit.

Pathophysiology

There are a variety of genetic, psychological, social and environmental factors which contribute to alcohol misuse.

Risk Factors

• High-Risk Occupations:
  • Publicans
  • Doctors
  • Journalists
  • Shipping And Travel Industries
• Unskilled Worker
• Unemployed
• Lower Social Class

Clinical Features

The recommended alcohol intake is 3-4 units for men and 2-3 units for women per day. Many people will drink more alcohol than this and it could be argued that this is alcohol misuse. However, the following categories are the important complications of alcohol misuse which need to be identified:

• Alcohol Dependence Syndrome
• Alcohol Withdrawal And Delirium
• Wernicke's Encephalopathy - caused by Thiamine/B1 deficiency
• Korsakoff's Psychosis
