Key result
Targeting insulin resistance improves stroke outcomes over glycemic control alone in preclinical diabetes.

Answers are grounded in this paper and cite their sources.
In a mouse model of type 2 diabetes, normalizing insulin resistance prior to stroke improves functional outcomes more than normalizing hyperglycemia.
Hyperglycemia and insulin resistance independently correlate with poor stroke outcomes in type 2 diabetes, although their causative role is unclear. The aim of this study was to determine experimentally whether normalizing insulin resistance rather than hyperglycemia before stroke improves stroke outcomes in type 2 diabetes. To answer this question, we specifically normalized either hyperglycemia or insulin resistance in obese, type 2 diabetic mice before inducing stroke. We show that targeting insulin resistance, rather than hyperglycemia, before stroke in type 2 diabetes is crucial to improving stroke outcomes.

Vercalsteren et al. (2026) studied Type 2 diabetes and stroke. Normalizing insulin resistance vs. Normalizing hyperglycemia was evaluated on Stroke outcomes. Targeting insulin resistance, rather than hyperglycemia, before stroke in a mouse model of type 2 diabetes improved stroke outcomes.
