There are many different types of brain injuries, including: anoxic injuries, contusions, concussions, and infections.
Anoxia is a serious medical condition characterized by a lack of oxygen being delivered to an organ or tissue in the body.
Some anoxic brain injury causes include stroke, cardiac arrest, low blood pressure, carbon monoxide poisoning, and choking.
Anoxic brain injury can occur when oxygen isn't able to reach the brain. Hyperbaric oxygen therapy could help treat an anoxic brain injury.
