How are the different types of anoxic brain injuries classified?

Dr. Jeanne Morrison, PhD
Family Practitioner

An anoxic brain injury can be classified into one of four categories based on what caused the oxygen deprivation. The most common is stagnant anoxia, which occurs when an internal condition blocks an adequate supply of oxygen-rich blood from entering the brain. If the anoxic brain injury is caused by an insufficient supply of oxygen in the air, it's classified as anoxic anoxia. When the anoxic brain injury is caused by toxins or metabolites interfering with the ability to process oxygen normally, it's called toxic anoxia. Anemic anoxia occurs when there are not adequate levels of blood or hemoglobin to carry oxygen to your brain.
