Which is the COMMONEST type of seizure in newborn?
Essentials of Diagnosis & Typical Features of Neonatal seizures: Usual onset at 12-48 hours. Seizure types include subtle (characterized by variable findings), tonic, and multifocal clonic. Most common causes include hypoxic-ischemic encephalopathy, intracranial bleeds, and infection. Most common type of seizures is newborn are subtle seizures and they constitute 50% of all seizures. Subtle seizures are usually mild paroxysmal alterations in motor behaviour or autonomic function that are not clearly clonic, tonic or myoclonic. Newborns rarely have well-organized tonic-clonic seizures because of their incomplete coical organization and a preponderance of inhibitory synapses. The most common type of seizure is characterized by a constellation of findings, including horizontal detion of the eyes with or without jerking; eyelid blinking or fluttering; sucking, smacking, drooling, and other oral-buccal movements; swimming, rowing, or paddling movements; and apneic spells.
