Theobromine Toxicity and Central Nervous System Effects

Overview

• Theobromine is a methylxanthine alkaloid found in cocoa, chocolate, and tea.
• Excessive intake can lead to acute or chronic toxicity, particularly in animals, but occasionally in humans.

Central Nervous System Impact

• Stimulant properties: Theobromine acts as a competitive non-selective phosphodiesterase inhibitor and adenosine receptor antagonist.
• Neurological symptoms: Toxicity frequently manifests as overstimulation of the central nervous system.
• Reported effects include:
• Restlessness and nervousness
• Tremors and muscle twitching
• Hyperreflexia
• Agitation and anxiety
• Seizures in severe overdose cases

Conclusion

• While theobromine toxicity primarily affects the cardiovascular and gastrointestinal systems first, it can indeed cause significant central nervous system excitation and damage when consumed in toxic amounts.
