T116. CAFFEINE-INDUCED PSYCHIATRIC MANIFESTATIONS

BACKGROUND: The association between caffeine consumption and various psychiatric manifestations has long been observed. METHODS: We present two cases that show the ability of caffeine to induce psychotic and manic symptoms, and we also review the extant literature on caffeine-induced psychiatric manifestations. RESULTS: On the basis of our own and others’ findings, we suggest that caffeine may be related to not only de-novo psychotic or mood symptoms but also to aggravation of pre-existing psychotic or mood disorders. DISCUSSION: We therefore suggest that caffeine consumption among patients with mood or psychotic symptoms should be assessed carefully in clinical practice as part of routine psychiatric evaluations.
