Febrile seizures (FS) are usually self-limiting and cause no morbidity. Nevertheless they represent very traumatic events for families. There is a need to identify key messages that reassure carers and help to prevent inappropriate, anxiety-driven behaviors associated with “fever phobia.” No recommendations have been proposed to date regarding the content of such messages. Using a Delphi process, we have established a consensus regarding the information to be shared with families following a FS. Twenty physicians (child neurologists and pediatricians) from five European countries participated in a three-step Delphi process between May 2018 and October 2019. In the first step, each expert was asked to give 10 to 15 free statements about FS. In the second and third steps, statements were scored and selected according to the expert ranking of importance. A list of key messages for families has emerged from this process, which offer reassurance about FS based on epidemiology, underlying mechanisms, and the emergency management of FS should they recur. Interestingly, there was a high level of agreement between child neurologists and general pediatricians. Conclusion: We propose key messages to be communicated with families in the post-FS clinic setting. What is Known: • Febrile seizures (FS) are traumatic events for families. • No guidelines exist on what information to share with parents following a FS. What is New: • A Delphi process involving child neurologists and pediatricians provides consensual statement about information to deliver after a febrile seizure. • We propose key messages to be communicated with families in the post-FS clinic setting.

Introduction: Epilepsy is more frequent in individuals with Autism Spectrum Disorder (ASD) than in the general population; however, its diagnosis is frequently challenging. Areas Covered: We report the current diagnostic criteria for both ASD and epilepsy. We describe the incidence, prevalence, and risk factors for epilepsy in patients with ASD. We then focus on the electro-clinical approach, including the clinical evaluation of cognitive regression. Expert Opinion: A diagnosis of epilepsy should be made based on the International League Against Epilepsy (ILAE) definition. A diagnosis of epilepsy should be established based on a single seizure with electroencephalography (EEG) abnormalities. Considering the high prevalence of EEG abnormalities in children with ASD without epilepsy, EEG should only be performed at epilepsy onset, and more precisely when a clinical interview has confirmed that repetitive paroxysmal events could be seizures. There are still many gaps in our understanding of epilepsy in patients with ASD. It would be of interest to further understand the links, if any, between EEG abnormalities and ASD phenotype. The identification of epilepsy syndromes in ASD would help analyze the possible underlying etiologies, for the administration of more appropriate antiepileptic drugs (AED), and to explain the prognosis to caregivers.
