Overview
Alcohol abuse encompasses a spectrum of unhealthy drinking behaviors, ranging from binge drinking and alcohol dependence (type 2 alcoholism) to addiction resulting in physical withdrawal symptoms ("the shakes," etc.) when abruptly stopping the intake of alcohol for more than 24 hours (type 1 alcoholism).
Alcohol abuse was a psychiatric diagnosis in the DSM-IV, and has been merged with alcohol dependence into alcohol use disorder in the DSM-5.
Globally, excessive alcohol consumption is the seventh leading risk factor for both death and the burden of disease and injury, representing 5.1% of the total global burden of disease and injury, measured in disability-adjusted life years (DALYs). In short, except for tobacco, alcohol accounts for a higher burden of disease than any other drug. Alcohol use is a major cause of preventable liver disease worldwide, and alcoholic liver disease is the main alcohol-related chronic medical illness. Millions of people of all ages, from adolescents to the elderly, engage in unhealthy drinking. Alcohol use disorder can affect people from all walks of life. There are many factors that play a role in causing someone to have an alcohol use disorder: genetics, psychiatric conditions, trauma, environmental issues, and even parental drinking habits.
