[Seizures in the neonatal period]
OBJECTIVE: To characterize and differentiate neonatal seizures from those that occur at different ages, based on a critical assessment of the available literature and also on the authorś clinical experience. SOURCES: Literature review, including up-to-date and classical studies that helped us to better understand clinical, neurophysiological and physiopathological aspects related to seizures in the newborn. SUMMARY OF THE FINDINGS: The authors present clinical and electroencephalographic characteristics of neonatal seizures, discuss their classification, treatment and prognosis. CONCLUSIONS: Neonatal seizures have a distinct clinical pattern, which justifies the necessity of an appropriate classification. The etiology is predominantly symptomatic and multifactorial; the treatment should follow a routine protocol, and the prognosis seems to be closely related to etiology.
