How it works
The DRAGON score estimates functional independence after IV thrombolysis for ischemic stroke using CT findings, demographics, glucose, NIHSS, and treatment delay.
Limits
Derived before modern endovascular era; discuss risk/benefit of thrombolysis and EVT with neurology—does not replace shared decision-making.
Educational tool only—not for diagnosis or treatment decisions.
