Caffeine-induced psychiatric manifestations: a review

Area of Science:

• Psychiatry
• Neuroscience
• Clinical Psychology

Background:

• Caffeine is a widely consumed psychoactive substance.
• Its association with psychiatric symptoms is recognized.
• Existing literature suggests a link between caffeine and mental health.

Observation:

• Two cases illustrate caffeine's potential to induce psychotic and manic symptoms.
• A review of existing literature supports these observations.
• Caffeine's impact on psychiatric manifestations is examined.

Findings:

• Caffeine may cause new-onset psychotic or mood symptoms.
• It can also exacerbate pre-existing psychotic or mood disorders.
• The dose-response relationship and individual susceptibility warrant further investigation.

Implications:

• Routine psychiatric evaluations should include caffeine consumption assessment.
• Understanding caffeine's role can improve patient management.
• Further research is needed to elucidate the mechanisms of caffeine-induced psychiatric effects.
