Caffeine-induced mania in a patient with caffeine use disorder: A case report

BACKGROUND, OBJECTIVES AND METHODS: Here, we report a case of a patient who reported using high dose caffeine and was observed with multiple episodes of caffeine-induced mania with psychotic features and met criteria for caffeine use disorder. RESULTS: To our knowledge, this is the first reported case of caffeine-induced mania in a patient that also specifically met criteria for caffeine use disorder. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: This case supports evidence that caffeine use disorder should be considered for inclusion in future diagnostic manuals as a potential drug of abuse pending additional research.
