Benign neonatal seizure syndromes can be characterized by familial or idiopathic seizures. Benign familial neonatal seizures typically occur in the first 48-72 hours of life; the seizures disappear by age 2-6 months. A family history of seizures is usual. Development is typically normal in these infants.

Benign idiopathic neonatal seizures typically present at day 5 of life (ie, fifth day fits), with the vast majority presenting between days 4 and 6 of life. Seizures are often multifocal. Cerebrospinal fluid (CSF) analysis is usually unremarkable.
