Alcohol withdrawal is a syndrome arising after a reduction or cessation of sustained alcohol exposure in a physiologically adapted person. Symptoms reflect altered regulation of neural activity and can range from tremor and autonomic activation to seizures or delirium tremens.

Alcohol withdrawal is distinct from current alcohol intoxication. The timing of exposure and its reduction matters when interpreting apparently similar changes in behavior or awareness.^[ref]

A substance use disorder involves a pattern of substance use associated with impaired control, harmful consequences or disruption of everyday functioning. It can vary in severity and can coexist with other mental disorders.^[ref]

Drug tolerance and Drug withdrawal are physiological concepts that may be relevant, but neither should be used alone as a complete account of the disorder. The pattern of use and its effects on a person's life are separate parts of the assessment.
