Another potential cause is disruption of adenosine triphosphate (ATP) ̶ dependent resting membrane potentials, which cause sodium to flow into the neuron and potassium to flow out of the neuron. Hypoxic-ischemic encephalopathy disrupts the ATP-dependent sodium-potassium pump and appears to cause excessive depolarization. It is an important cause of neonatal seizures. [1, 4]

Seizures resulting from hypoxic-ischemic encephalopathy may be seen in term and premature infants. They frequently present within the first 72 hours of life. Seizures may include subtle, clonic, or generalized seizures.
