DEFINITION

• Caffienated foods and beverages are regularly consumed by more than 85% of adults and children in the U.S.[1]
• Caffeine use disorder refers to disruptive, problematic pattern of caffeine use leading to clinically significant impairment or distress. Common features of the disorder include overuse, inability to quit, withdrawal symptoms, craving, tolerance, and continuing to use despite problems.
• Caffeine use disorder is considered a condition for further study in DSM-5. The closely related caffeine dependence syndrome is a recognized disorder in ICD-10. 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[2].
