Neuroimaging in neonatal seizures.

Area of Science:

• Neonatal Neurology
• Pediatric Neuroimaging
• Clinical Neuroscience

Background:

• Seizures are the most frequent neurological dysfunction in full-term neonates.
• Neonatal seizures indicate severe brain injury, leading to high mortality and morbidity.
• Accurate diagnosis of underlying brain lesions is essential for prognosis.

Purpose of the Study:

• To review the spectrum of neuroimaging findings in full-term newborns with seizures.
• To categorize findings based on underlying etiologies.
• To present a standard neonatal MRI protocol.

Main Methods:

• Review of existing literature on neuroimaging in neonatal seizures.
• Categorization of MRI findings by underlying causes (e.g., hypoxic-ischemic encephalopathy, stroke, metabolic disorders).
• Description of a standardized MRI protocol for neonatal seizure evaluation.

Main Results:

• Limited data exists on neuroimaging in neonatal seizures.
• Most studies focus on specific etiologies rather than a broad spectrum.
• Neuroimaging findings vary significantly depending on the cause of seizures.

Conclusions:

• Neuroimaging, particularly MRI, is vital for diagnosing the cause of neonatal seizures.
• Understanding the range of neuroimaging findings aids in identifying underlying brain pathologies.
• A standardized MRI protocol can improve diagnostic consistency.
