Virginia stroke window period expert witnesses assess whether stroke symptoms were recognized and treated within evidence-based thrombolysis and thrombectomy timeframes. They commonly come from vascular neurology, emergency medicine, neuroradiology, and EMS leadership. In Virginia, they often draw on practices seen at VCU Health and other regional stroke centers serving rural-to-urban transfers. They evaluate door-to-needle metrics, imaging interpretation, handoff delays, and eligibility decisions.
