What can be dangerous for the central nervous system of blood supply disturbances caused by trauma or hemorrhage?

The brain is the main consumer of energy and oxygen in the body. This organ controls the work of all other systems and therefore especially needs nutrition and oxygen. In case of disturbances in blood supply, blood will not flow to the brain and nerves (or it will flow with difficulty), as a result, the nervous system will feel a lack of oxygen. Hypoxia (oxygen starvation) will set in, and the cells will begin to die off. An example of such a disorder is a stroke, after which some patients lose the ability to control some parts of the body.
