Hypoxia means a lack of oxygen to any tissue or organ in the body. Cerebral hypoxia refers to a decrease of oxygen supply to the cerebrum in the brain, even if there is normal blood flow.

Symptoms of mild cerebral hypoxia include inattentiveness, poor judgment, memory loss, and a decrease in motor coordination. Prolonged hypoxia can cause coma, seizures, and even brain death.

Hypoxia is a possible secondary complication that can develop over a period of hours to days after the initial TBI.
