Neonatal status epilepticus II: Electroencephalographic aspects.

G Olmos-Garcia de Alba, E Udaeta Mora, J Malagon Valdez

    Clinical EEG (Electroencephalography)
    |October 1, 1984
    PubMed
    Summary

    Neonatal seizures (NS) can be electrical only, without clinical signs. This study found that 11 of 15 newborns had electrical-only neonatal seizures (ENSE), while 4 had both electrical and clinical seizures (ECNSE).

    Area of Science:

    • Neonatal neurology
    • Clinical neurophysiology

    Background:

    • Neonatal seizures (NS) are a critical concern in newborns.
    • Distinguishing clinical seizures from subclinical events is challenging.

    Purpose of the Study:

    • To characterize the presentation of neonatal seizures in a prospective cohort.
    • To differentiate between electrical-only neonatal seizures (ENSE) and those with clinical manifestations (ECNSE).

    Main Methods:

    • Prospective identification of 15 newborns with neonatal seizures.
    • Clinical assessment for seizure manifestations.
    • Electroencephalogram (EEG) monitoring to detect electrical discharges.

    Main Results:

    • 15 newborns were identified with neonatal seizures.

    Related Experiment Videos

  • 11 cases (73%) exhibited electrical discharges without observable clinical signs (ENSE).
  • 4 cases (27%) presented with simultaneous clinical seizures and electrical discharges (ECNSE).

    • Conclusions:

    • A significant proportion of neonatal seizures may be subclinical, presenting as electrical-only events (ENSE).
    • Clinical observation alone may underestimate the incidence of neonatal seizures.
    • Further research is needed to understand the implications of ENSE.
