Hypoxic Ischemic Encephalopathy: An Ayurvedic Review and Treatment: A Case Study
Abstract: One of the most severe and potentially fatal conditions of the infant brain that can develop before or during delivery is HIE. Common definitions of HIE include HYPOXIC (insufficient oxygen), ISCHEMIC (insufficient blood flow), and ENCEPHALOPATHY (brain disease). It is a terrible disease that can leave children with severe neurologic deficits or even kill them. HIE happens when a baby's brain receives insufficient oxygen and blood (perinatal hypoxia), which results …
