Seizures in fetal alcohol spectrum disorders: evaluation of clinical, electroencephalographic, and neuroradiologic features in a pediatric case series.

Seizures are observed with a frequency of 3-21% in children with fetal alcohol spectrum disorders (FASD). However, clinical, neuroradiologic, and electroencephalography (EEG) features are poorly described. In this study, 13 patients with FASD and epilepsy or seizures were identified retrospectively from the databases of seven Italian pediatric neurology divisions. Eleven children were affected by epilepsy, and two had at least one documented seizure. Both generalized and focal seizures were observed. EEG showed diffuse or focal epileptic activity; two children developed electric status epilepticus during sleep (ESES). Structural brain anomalies, including polymicrogyria, nodular heterotopia, atrophy, and Arnold-Chiari type 1 malformation, were discovered in almost 50% of patients. Control of seizures was not difficult to obtain in 11 cases; one patient showed pharmacoresistant epilepsy. EEG and clinical follow-up are recommended in children with FASD and epilepsy, since severe conditions requiring aggressive treatment, such as in ESES, may develop. Neuroradiological evaluation is warranted because several types of brain anomalies could be associated with maternal alcohol consumption during pregnancy.
