WebHypoxic-ischemic encephalopathy is the most common cause of neonatal seizures in both full-term and premature infants accounting for close to one-half of the causes (see Chapters 16 and 18). The EEG tracings could be analyzed in 31 newborns, including 15 who received therapeutic hypothermia and 16 who did not receive therapeutic hypothermia. Encephalopathy from head injuries, toxins, cardiac arrest, or lack of oxygen to the brain causes physical damage to the brain that is usually permanent. Ischemia = decreased blood flow.
