Which of the following is the cause of neural damage following a cerebrovascular accident
A)reduced CO₂ and increased glucose delivery to the region of the brain deprived of its blood supply
B)toxic release of glutamate from damaged brain cells, which overexcites and subsequently destroys surrounding brain cells
C)a loss of the blood-brain barrier in the affected area of the brain as a result of rupture or occlusion of a cerebral vessel
D)decreased production of ATP in the absence of oxygen

The toxic release of glutamate from damaged brain cells is a major cause of neural damage following a cerebrovascular accident. Glutamate overexcites and subsequently destroys surrounding brain cells through a process known as excitotoxicity. This can lead to further damage to the brain and worsen the outcome of the stroke.
