Which term stands for reversible ischemic neurological deficit?

• A. Reversible Ischemic Neurological Deficit
• B. Rapid Ischemic Neurological Disorder
• C. Residual Ischemic Neurological Deficit
• D. Recurrent Ischemic Neurological Delay

Answer: (A)

Reversible Ischemic Neurological Deficit describes a cerebral ischemic event where the neurological symptoms completely resolve after a period of time. It captures deficits caused by transient lack of blood flow that are not long enough to cause permanent brain damage, so function returns as soon as perfusion improves. This term sits conceptually between a transient ischemic attack, which is usually defined by symptoms lasting less than 24 hours, and a full stroke, which leaves lasting deficits from tissue infarction. The choice literally conveys reversibility of the deficit due to ischemia, which is why it’s the best match. The other phrases aren’t standard terms for this phenomenon and don’t convey the reversibility aspect: they imply residual, delayed, or recurrent issues that don’t inherently describe complete recovery.
