One of Greta’s close friends from the Latvian club has a daughter who is a second year student nurse. Greta has asked if you can explain the pathophysiology of a Cerebrovascular Accident (stroke) and how it affects the central nervous system to her friend’s daughter, as she doesn’t understand and has an exam approaching. Greta has given her permission for you to use her as an example. Please explain the pathophysiology of a Cerebrovascular Accident (stroke) and how it affects the central nervous system using the correct medical and nursing terminology.
