Which term describes a vascular change that temporarily deprives part of the brain of oxygen but does not cause lasting deficits?

Which term describes a vascular change that temporarily deprives part of the brain of oxygen but does not cause lasting deficits?

• A. TIA
• B. Stroke
• C. CVA
• D. Transient Ischemic Attack

Answer: (A)

Transient ischemic attack is a brief interruption of blood flow to a brain region that causes stroke‑like symptoms but heals completely, leaving no lasting deficits. This means the symptoms—such as weakness, trouble speaking, numbness, or vision changes—appear suddenly and then resolve without permanent brain injury. Because TIAs look like a mini-stroke, they deserve urgent evaluation to identify risk factors and prevent a future, more damaging stroke. A stroke, or cerebrovascular accident, involves actual brain tissue damage from prolonged ischemia, leading to lasting deficits. The term Transient Ischemic Attack (TI A) and its abbreviation describe the same event, with TI A being the shorter form often used in practice.
