[Neonatal seizures: evaluation, diagnosis, and treatment]

Seizures have a high incidence in the neonatal stage, being the main manifestation of neurological dysfunction. Certain physiological conditions of the neonatal brain facilitate its appearance. Its diagnosis can be a challenging because its semiology is not as clear as in older children, furthermore, confirmation by either EEG or aEEG is necessary. Its timely recognition is very important for adequate treatment and thus avoid a negative impact on the long-term outcome. In the following review, we recapitulate the pathophysiology, causes, and classification of neonatal seizures, as well as their correct approach and the best therapeutic options for their treatment depending on the cause.
