DEFINITION

• Caffeinated foods and beverages are regularly consumed by more than 90% of adults and a high proportion of children and adolescents in the U.S.[1]
• Caffeine use disorder (CUD) refers to disruptive, problematic pattern of caffeine use leading to clinically significant impairment or distress. Common features of the disorder include failure to control use, continued use despite harm, and withdrawal and may include craving, tolerance and consuming more than intended.
• Caffeine use disorder is considered a condition for further study in DSM-5 (Section III)[2] and is not yet fully recognized by the DSM-5. The ICD-11 includes a closely related caffeine dependence syndrome that mirrors the proposed DSM-5 criteria. This addiction disorder is characterized by use of caffeine in patterns and amounts that lead to clinically significant disturbance or distress.
• Not discussed here are four additional DSM-5 caffeine-related disorders: caffeine intoxication, caffeine withdrawal, caffeine-induced anxiety disorder, and caffeine-induced sleep disorder[3].
