An anoxic brain injury occurs when a brain injury or certain kinds of disease processes deprive the brain of oxygen. When this oxygen deprivation occurs, brain cells can start to die within five minutes. This causes a whole host of problems, including impairment of electrochemical impulse transmission. When electrochemical impulse transmission is disrupted, chemical messengers called neurotransmitters are affected. Neurotransmitters control a wide variety of significant physiological, cognitive, and emotional processes, so any disruption in their activity can have profound effects on a person.
