Alcohol dependence was earlier referred to as 'Alcoholism'. Alcohol dependence is more common among males.

It usually sets in during the latter part of the second decade or during the early part of the third decade of life.

The term 'Alcohol dependence' is usually used in reference to the mental, physical, or social damage that results from an excessive consumption of alcohol. Alcohol dependence is characterized by an increased preoccupation with the drug and reduced control over its intake.

Alcohol dependence is often a chronic, progressive disease, which, if left untreated, can prove to be fatal.

Alcohol dependence may also be contributed by genetic, psychological, and social factors.

Alcohol abuse is generally considered when a person engages in excessive drinking, resulting in health or social problems, but is not dependent on alcohol on a regular basis. Excess of alcohol affects the central nervous system and the functions of the brain.

It generally affects the perception, thinking, and coordination, impairing judgment, reducing inhibitions, and increasing the person’s aggressiveness.

Alcohol abusers are often more likely to be associated with high-risk, reckless, or violent behaviours than non-abusers.
