 Are such disorders the result of common physiopathological mechanisms, which precede the development of the epilepsy? The link between an underlying brain disorder and psychiatric comorbidities has emerged in recent literature, with evidence based on studies in adults, suggesting bidirectional relations between epilepsy and neurobehavioural comorbidities. Emotional regulation disorders can follow the onset of epilepsy, but they can also precede it, thus serving as a possible risk factor. The clinical implication of such a bidirectional association is that neurobehavioural comorbidities might be present at diagnosis and even before epilepsy onset. There is a need for greater understanding of the causes of these conditions in younger people.
