70% brain damage, not in a single area, due to lack of oxygen (caused by asphyxia), what are the chances to awaken and regain full consciousness?

70% brain damage, not in a single area, due to lack of oxygen (caused by asphyxia), what are the chances to awaken and regain full consciousness?

Unlikely: The extent of brain damage is not as important as the specific areas of the brain that are affected. So, if the pons or medulla were affected, you would be considered brain dead already. But, if you loose that much area, you will have significant mental status changes and impairments of motor function. This is not a good circumstance. ...Read more

Can you heal or reverse brain damage cause at birth from lack of blood and oxygen to the brain with healing foods or any break through medications?

I'm sorry: Please forgive my frankness. Charlatans prey on the desperation of handicapped people to make money. Anyone offering you "healing foods" or some magic supplement is trying to scam you.
