Which term describes a stroke lasting longer than 24 hours with permanent damage?

Which term describes a stroke lasting longer than 24 hours with permanent damage?

• A. CVA (Cerebrovascular Attack)
• B. TIA (Transient Ischemic Attack)
• C. ICH (Intracerebral Hemorrhage)
• D. SAH (Subarachnoid Hemorrhage)

Answer: (A)

This question tests how to tell apart a transient ischemic attack from a stroke by duration and permanent damage. A Transient Ischemic Attack is a brief disruption of blood flow that resolves within 24 hours and does not cause permanent brain injury. When symptoms persist longer than 24 hours and leave permanent deficits, the event is described as a cerebrovascular accident. Historically, CVA denotes a stroke with irreversible brain injury. The other terms refer to bleeding-related strokes (intracerebral or subarachnoid hemorrhage), which are different categories of stroke, but the defining criterion here is duration with lasting damage, which fits CVA.
