[Treatment of neonatal seizures]. / Tratamiento de las convulsiones neonatales.

ABSTRACT

Neonatal seizures are among the most dramatic manifestations of acute central nervous system dysfunction. The incidence is much higher in very low weight neonates than in full term infants (˜ 58 and 3.5 per 100 live births, respectively). Neonatal seizures represent the clinical manifestation of a non-specific cortical cerebral dysfunction which can lead to permanent brain injury. The etiology is multifactorial and requires a judicious assessment for each clinical scenario. The diagnosis is further complicated by the fact that most neonatal seizures are subclinical, that is, may display very subtle or no clinical changes and the diagnosis may just be based on EEG findings. The treatment depends on the etiology, but an early and opportune intervention prevents further brain damage, thus improving prognosis. Although early identification and treatment are critical, the diagnosis of neonatal seizures is complicated by several factors such as different clinical presentations, possible etiologies and several treatment options. Nevertheless, research studies and clinical evidence have shown that early treatment with anti-seizure medications can change the outcome.
