Brain Frailty Mediates the Lack of Endovascular Thrombectomy Benefit in Older Adults
Key Highlights
Medicine · Neurology
A new analysis from the RESILIENT trial reveals that baseline computed tomography markers of cerebral small vessel disease (cSVD), a surrogate for brain frailty, mediate the association between advanced age and poor functional outcomes after stroke. Researchers found that mechanical thrombectomy (MT) provided significant benefit only in patients under 70 with low cSVD burden, with no benefit observed in older patients or those with higher cSVD scores. For Dr. Viswanathan, this insight underscores the importance of assessing vascular frailty beyond chronological age—a concept directly transferable to diabetic populations where cerebrovascular disease and cognitive decline are major complications, potentially refining patient selection for interventions and advancing personalized care in India.
