The postnatal history is also significant. Neonatal seizures in infants with an uneventful antenatal history and delivery may result from a postnatal cause. A history of tremulousness may suggest drug withdrawal or neonatal hypocalcemia. Temperature and/or blood pressure instability may suggest an infection; a sepsis workup may be required.

A history of rubella or the absence of immunization against rubella may offer a diagnostic clue. In the United States, rubella immunization typically is given during the toddler years to both sexes and the degree of immunity is high. In countries where only teenage girls are immunized for rubella, neonatal seizures resulting from central nervous system (CNS) rubella involvement is a greater threat.
