Hypoxic ischemic encephalopathy (HIE) is a term for brain damage caused by lack of oxygen and lack of blood flow to the brain. Damage can occur within minutes. Once brain damage occurs, it is irreversible.
Very often the injury occurs during birth, due to birth accidents such as uterine rupture, knot in the umbilical cord, cord wrapped around the baby's neck, breech birth or other difficult births. However, HIE can also be a result of stroke, drowning, hanging, or any other event which would cut off oxygen and blood flow to the brain. The damage can also occur in utero. In some instances of babies born with HIE, the cause is never determined.
Children who are diagnosed with HIE can range from mild to severe in the amount of damage that has occurred. EEGs, MRIs and CAT scans are used to determine the severity and location of the brain injury. Clinical definitions of the way that physicians diagnose HIE can be found at http://www.peds.umn.edu/divisions/neonat... . This site also lists the three types of HIE, mild, moderate and severe, and gives an explanation of each.
This damage can be an underlying cause of cerebral palsy, mental retardation, dysphagia, cortical vision impairment or blindness, hearing impairment or deafness, microcephaly, temperature instability, chronic lung disease, and seizures. Prognosis given is often bleak in terms of the child's future abilities or quality of life. However, just like any other child, a child with disabilities is unique in his or her strengths and needs.
There is no treatment for HIE per se. Treatment in the form of therapies can help with muscle tone and control, oral muscle development, and vision in the case of cortical vision impairment. Traditional therapies include physical therapy for gross motor control, occupational therapy for small muscle control, and speech and language therapy. Oral stimulation is a form of therapy that is done by either the OT or the SLT depending on their particular qualifications. There are many alternative therapies that can be attempted as well, although the benefits of these are not considered to be proven.
Very little is found on the web or anywhere else about this condition. Because it is an underlying condition of so many disabilities, specialists often know about their own specialty only and not the other needs that the child has. This makes it hard for the parent to coordinate care and be sure to adequately address all of the child's needs.

It depends on the area of the brain which is damaged. If the auditory or visual area is damaged, it is possible.
