Stroke

Stroke is also called cerebrovascular accident (CVA). It results from damage to the brain caused by sudden interruption of its blood supply. This deprives the brain of oxygen and nutrients, and also triggers a chain event of “emergency” responses. Some of those responses are clearly helpful – such as reduction of activity in the “penumbra”; but other physiological responses are clearly destructive – such as the derangement of inflammatory responses.
