Examining the etiology and types of neonatal seizure (A review)
Journal Title: International Journal of Medical and Health Research - Year 2018, Vol 4, Issue 5
Abstract
Introduction: There are five main types of neonatal seizures: minor subunit seizures, clonic seizures, tonic seizures, spasms, focal clonic or tonic seizures, and myoclonic seizures associated with aligotr graphic disorder (epileptic seizures). While kinetic automatisms, septic seizures, clonic tonic and multifocal myoclonic seizures are not usually associated with EEG discharges, therefore, these seizures are considered to be more indicative of the phenomenon of release; these disorders are abnormal movements caused by brain damage rather than actual epileptic seizures. Methods: Searches were conducted by two independent researchers in international (PubMed, Web of science, Scopus and Google scholar) and national (SID, Magiran) databases for related studies from the inception of the databases to September 2017 (without time limitation) in English and Persian languages. To ensure literature saturation, the reference lists of included studies or relevant reviews identifed through the search were scanned. Discussion: With a frequency of 50-60%, hypoxic ischemic encephalopathy is the most common cause of neonatal seizures. Seizures resulting from this encephalopathy occur within the first 12 hours of birth. vascular events include intracranial and ischemic hemorrhage, accounting for 10 to 20 percent of cases of seizure. Bacterial and non-bacterial infections account for 5 to 10% of cases of neonatal seizures and Brain malformations cause 5 to 10 percent of cases of neonatal seizures.
