What sort of disorder is a cerebral vascular accident?

Brain vessel block. A cerebral vascular accident (cva) occurs when a clot lodges in a brain vessel and blocks it off, or when a vessels leaks and obstructs brain circulation and may result from an obstructing tumor. The part of the brain with vessel blocked off will lose its function leaving the patient with some dysfunction like one sided paralysis, or unable to speak, or many other problems.
