Which characteristic or symptom identifies a person suffering from alcoholism?

A person suffering from alcoholism often exhibits both physical and psychological dependence on alcohol. Physical dependence refers to the body's adaptation to alcohol, which can result in withdrawal symptoms when consumption is reduced or stopped. This could manifest as tremors, anxiety, or even severe complications in extreme cases.

Psychological dependence, on the other hand, involves an emotional or mental reliance on alcohol. Individuals may feel compelled to drink to cope with stress, anxiety, or other emotional issues, leading to compulsive drinking behavior despite negative consequences.

When both forms of dependence are present, it solidifies the diagnosis of alcoholism, as the individual struggles to control their drinking due to both the physiological effects and the psychological cravings associated with alcohol consumption.

Infrequent consumption does not characterize a person suffering from alcoholism, as it contradicts the very nature of the disorder, which involves a habitual and often excessive intake of alcohol.
