Clinical manifestations of neonatal seizures

Thuy Nguyen et al. Pediatr Int. 2021 Jun.

Abstract

Neonatal seizures present a unique diagnostic challenge with clinical manifestations often subtle or absent to the bedside observer. Seizures can be overdiagnosed in newborns with unusual paroxysmal movements and underdiagnosed in newborns without clinical signs of seizures. Electroclinical "uncoupling" also adds to the diagnostic challenge. Reliable diagnosis requires additional tools; continuous electroencephalogram (EEG) monitoring is the gold standard for diagnosis of neonatal seizures. Certain high-risk neonatal populations with known brain injury, such as stroke or hypoxic-ischemic encephalopathy, are most likely to benefit from continuous EEG. Studies have shown that risk stratification for continuous EEG has positive impact on care, including rapid and accurate diagnosis and treatment of neonatal seizures, which leads to reduced use of antiseizure medicines and length of hospital stay. This review describes common clinical manifestations of neonatal seizures, and clinical situations in which EEG monitoring to screen for seizures should be considered.
