Summary
A preceding transient ischemic attack (TIA) may offer neuroprotection in acute ischemic stroke (AIS) patients undergoing endovascular therapy (EVT). This TIA benefit, observed within 96 hours, is linked to improved functional independence and is partially mediated by the immune-inflammation index.
Area of Science:
- Neurology
- Stroke Medicine
- Immunology
Background:
- The neuroprotective effect of transient ischemic attack (TIA) preceding acute ischemic stroke (AIS) is not well understood.
- Investigating this association is crucial for understanding stroke recovery and treatment optimization.
Purpose of the Study:
- To determine if a preceding TIA within 96 hours of AIS improves functional outcomes in patients treated with endovascular therapy (EVT).
- To explore the role of the systemic immune-inflammation index (SII) in mediating the potential benefits of TIA.
Main Methods:
- Retrospective analysis of 887 AIS patients undergoing EVT.
- Propensity score matching (PSM) to balance groups with and without preceding TIA (within 96 hours).
- Evaluation of stroke severity at onset and functional independence at 3 months, including SII assessment.
Main Results:
- After PSM, 73 patients with TIA and 217 without TIA were compared.
- No significant difference in onset stroke severity was found between groups.
- Preceding TIA was associated with significantly improved 3-month functional independence (aOR 2.852) and was partially mediated by lower SII.
Conclusions:
- Preceding TIA within 96 hours is linked to better functional independence in AIS patients treated with EVT.
- The neuroprotective effect of TIA may be partly explained by its modulation of the systemic immune-inflammation index.
- Further research is warranted to elucidate the mechanisms and clinical implications of TIA-induced neuroprotection.

01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
