Neonatal encephalopathy (NE), previously known as neonatal hypoxic-ischemic encephalopathy (neonatal HIE or NHIE), is defined as a encephalopathy syndrome with signs and symptoms of abnormal neurological function, in the first few days of life in an infant born after 35 weeks of gestation.
Hypoxic ischemic encephalopathy has many causes and is defined essentially as the reduction in the supply of blood or oxygen to a baby's brain before, during, or even after birth. It is a major cause of death and disability, occurring in approximately 2–3 per 1000 births and causing around 20% of all cases of cerebral palsy. A 2013 Cochrane ...
Hypoxic ischemic encephalopathy (HIE) is a condition that occurs when the brain is deprived of an adequate oxygen supply, and is most commonly observed in newborn babies due to birth asphyxia. It is the leading cause of cerebral palsy, an irreversible neonatal brain injury that can result in long-term cognitive, motor, and visual impairments ...
Hypoxic ischemic encephalopathy (HIE) is a condition that occurs when the entire brain is deprived of an adequate oxygen supply, but the deprivation is not total. While HIE is associated in most cases with oxygen deprivation in the neonate due to birth asphyxia , it can occur in all age groups, and is often a complication of cardiac arrest .
Sarnat staging, Sarnat Classification or the Sarnat Grading Scale is a classification scale for hypoxic-ischaemic encephalopathy of the newborn (HIE), a syndrome caused by a lack of adequate oxygenation around the time of birth which manifests as altered consciousness, altered muscle tone, and seizures.

Infants who do give indications of stroke in the womb or shortly after birth commonly experience seizures. [3] When an infant has a seizure, they experience jerking in the face, legs, or arms, alongside delayed breathing. [4] Seizures are mostly caused by hypoxic-ischemic encephalopathy (HIE) or perinatal asphyxia. [34]
With hypoxic ischemic encephalopathy being the most common cause in full term infants and intraventricular hemorrhage as the most common cause in preterm infants. [4] According to the International League against Epilepsy (ILAE), seizures are defined as excessive or synchronous neuronal activity in the brain that is manifested as signs or ...
