Cerebral hypoxia is a form of hypoxia (reduced supply of oxygen), specifically involving the brain; when the brain is completely deprived of oxygen, it is called cerebral anoxia. There are four categories of cerebral hypoxia; they are, in order of increasing severity: diffuse cerebral hypoxia (DCH), focal cerebral ischemia , cerebral infarction ...
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Hypoxia can be due to external causes, when the breathing gas is hypoxic, or internal causes, such as reduced effectiveness of gas transfer in the lungs, reduced capacity of the blood to carry oxygen, compromised general or local perfusion, or inability of the affected tissues to extract oxygen from, or metabolically process, an adequate supply ...

If you decide to go for a jog in humid, 95-degree weather this summer, your body and brain could start to have some strange reactions.
Hypoxic conditions in severely anemic individuals may cause brain damage resulting in cognitive impairment. [32] When iron levels in the brain are disrupted neurophysiological mechanisms and cognition are affected, potentially resulting in long-term behavioral changes and may affect attention span, intelligence, sensory perception functions ...
The brain can be deprived of oxygen with as little as 4.4 pounds of pressure and can cause loss of consciousness in just ten seconds. When hypoxia begins, permanent brain damage can occur within ...
A man with brain damage and trapped in a coma-like state for six years was brought back to consciousness in 2003 by doctors who planted electrodes deep inside his brain. The method, called deep brain stimulation (DBS), successfully roused communication, complex movement and eating ability in the man with a traumatic brain injury.
