The advantages of metaphorical representation are pointed out in many fields of clinical research (e.g. cancer, HIV, psychogenic nonepileptic seizures). This study aimed at offering a novel contribution showing how children with epilepsy describe the symptomatology of their seizure experiences by means of particular kinds of cognitive metaphors. Twenty-three children with idiopathic generalized epilepsy and thirty-one healthy children were recruited for this study and interviewed with a multiple-choice questionnaire asking them to describe their epileptic seizures by means of suitable metaphors. A psychologist blinded to medical diagnosis assessed and categorized all metaphors.By considering the 89 metaphors produced by the children with epilepsy and the 147 ones by the healthy controls, Agent/Force was the primary metaphor assessed by children with epilepsy, followed by Event/Situation as the second preference. Moreover, comparing the results of the control group with those of the subjects with epilepsy, it was found that controls were oriented towards selecting exogenous forces, while subjects with epilepsy tended to select endogenous forces. In particular, children with epilepsy showed a peculiar preference for an endogenous force resembling the waggle metaphor, which is similar to the effect of a quake's shaking (earthquake or seaquake). The metaphors identified by this research are a useful resource to better understand the seizure experiences of patients with epilepsy, helping to improve clinical treatment.
