RIND
Pronunciation: rind
Also written as: RIND — Reversible Ischemic Neurological Deficit
Reversible Ischemic Neurological Deficit, describing neurological symptoms that resolve within 24 hours but with residual imaging changes.
Full Definition
RIND (Reversible Ischemic Neurological Deficit) is a clinical term describing transient neurological symptoms lasting longer than a TIA (>24 hours) but with complete clinical recovery, often accompanied by permanent imaging changes on MRI or CT. Unlike TIA, RIND typically shows tissue damage on diffusion-weighted MRI, making imaging correlation crucial for accurate diagnosis. This term is important in vascular imaging reports as it helps distinguish between different categories of cerebrovascular events and guides treatment decisions. Editors must understand that RIND represents an intermediate category between TIA and completed stroke, and the term has evolved with improved imaging capabilities. Some modern classifications have moved away from time-based definitions in favor of tissue-based criteria.
Usage
Usage note: Capitalize when abbreviated; some institutions prefer tissue-based over time-based stroke classifications.
In Context
- "The patient's symptoms suggested RIND with corresponding DWI changes on MRI." — Stroke evaluation report
- "Despite clinical recovery, imaging confirmed tissue injury consistent with RIND rather than TIA." — Neurovascular assessment
