What condition results from a stop in oxygen supply to the brain?

The condition characterized by a complete stop in the oxygen supply to the brain is referred to as anoxia. Anoxia indicates that the brain is not receiving any oxygen at all, which can lead to serious neurological damage or death if the oxygen deprivation lasts for a significant duration.

This definition highlights the critical nature of oxygen for brain health and function, as the brain is highly sensitive to oxygen deprivation. Without oxygen, brain cell function rapidly ceases, leading to cell death and subsequent neurological impairments.

Hypoxia, on the other hand, refers to a deficiency in the amount of oxygen reaching the tissues, where there may still be some oxygen present, albeit insufficient. Hydrocephalus involves an accumulation of cerebrospinal fluid in the brain, leading to increased intracranial pressure, and coup-contracoup describes brain injuries caused by an impact that leads to injury at both the site of impact and the opposite side of the brain. All these conditions differ significantly from anoxia in terms of their definitions and implications.
