Differential Diagnosis for Convulsions in Newborn

Single Most Likely Diagnosis

  • Hypoxic-Ischemic Encephalopathy (HIE): This condition is a common cause of seizures in newborns, resulting from lack of oxygen and blood flow to the brain, often due to complications during delivery.

Other Likely Diagnoses

  • Infection (Meningitis, Sepsis): Newborns are susceptible to infections, which can cause seizures. Early diagnosis and treatment are crucial.
  • Metabolic Disorders (Hypoglycemia, Hypocalcemia): Abnormal levels of glucose, calcium, or other electrolytes can lead to seizures in newborns.
  • Congenital Malformations or Structural Brain Abnormalities: Anomalies in brain development can cause seizures, and some may be detected prenatally or shortly after birth.

Do Not Miss Diagnoses

  • Intracranial Hemorrhage: Bleeding within the brain can cause seizures and is critical to diagnose promptly due to the potential for severe outcomes.
  • Pyridoxine-Dependent Epilepsy: A rare condition where seizures are resistant to conventional antiepileptic drugs but respond to pyridoxine (vitamin B6), making it crucial for early diagnosis.
  • Herpes Simplex Virus (HSV) Infection: Neonatal HSV can present with seizures among other symptoms, and early antiviral treatment is essential to prevent severe neurological damage.

Rare Diagnoses

  • Tuberous Sclerosis Complex: A genetic disorder that can cause seizures, skin lesions, and other systemic manifestations.
  • Mitochondrial Disorders: A group of conditions affecting the mitochondria, which can lead to seizures among a wide range of other symptoms.
  • Kernicterus: A condition caused by severe jaundice leading to brain damage and potentially seizures, though rare due to modern management of neonatal jaundice.
