What's inside
Three things that make NeuroScan different.
Most camera-based screeners check static asymmetry — which fails the moment a person is already mid-stroke. We rebuilt the approach from the ground up.
A five-phase guided test
Rest, smile, close eyes, open eyes wide, smile again. Each step is grounded in the cranial-nerve anatomy used by ER doctors today.

We measure how each side responds to a command — not how it looks at rest. That makes the test robust even when the baseline is already affected.
