Reflex epilepsies can be defined as epilepsies in which all or a significant part of seizures can be regularly provoked by a given triggering factor, most often a sensory stimulus. Sometimes it may be unexpected, such as, reading or decision-making. We report an unusual epilepsy in which seizures occurred when the patient lied.As unpleasant as it is for the real subject, this sounds like a comedic premise.
As in Collodi's tale, in which lies made Pinocchio's nose grow, our patient's lies became so obvious for his interlocutors. As he was a "eurocrat", using lies to evoke the truth in adversarial EEC negoations, it is thanks to carbamazepine [an anticonvulsant and mood-stabilizer] that he has been able to work again.
