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.
A neonatal seizure is a seizure in a baby younger than age 4-weeks that is identifiable by an electrical recording of the brain. [1] It is an occurrence of abnormal, paroxysmal, and persistent ictal rhythm with an amplitude of 2 microvolts in the electroencephalogram,. [2]
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 .
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 ...
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.

When Ferriero was appointed assistant professor at UCSF, she began working with Roger P. Simon, a neurologist who had created a model of adult hypoxic-ischemic encephalopathy (HIE). Together they created a rodent model of neonatal HIE. [3] This allowed Ferriero to study oxidative stress following asphyxia in a developing brain.
Finland handed the defending champion United States its first loss at the 2025 world junior hockey championship as Tuomas Uronen scored in overtime for a 4-3 win on Sunday afternoon.
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]
