The proof

Meet the next dizzy patient having already made this call — inner ear or stroke — hundreds of times.

Read the eyes, make the call, see the reasoning — on an endless supply of worked dizzy cases that lean on the signs you miss.

Head impulse · derived from the physics
Counterfactual twin
Generated live · answer derived from the physics

Two days of continuous dizziness, present now at rest and worse with any head movement. It began at rest, with nothing that set it off. Hearing is unchanged. No limb weakness, no numbness, no trouble speaking.

Two patients, the same story. Everything looks the same — until you flick the head. One eye makes a catch-up saccade; one does not. Which one is the central call — the stroke until proven otherwise?

Patient A
Patient B
Run the head impulse on both, then make your call.

Stylised teaching animation from a physics engine — not a real-patient recording, not a diagnosis.

The counterfactual twin. The head impulse on two patients with identical acute vestibular syndrome; the only parameter changed is the reflex gain, and the correct call is derived from the same kinematics that draw the eyes. Stylised teaching, exaggerated for visibility — not a recording of a patient, and not a diagnosis. After Kattah et al., 2009 (Stroke).

That pair was generated when this page loaded. Pro is the same engine, with no daily cap.

Evidence · cited in full

In acute vestibular syndrome, a trained examiner reading the eyes at the bedside can outperform early MRI: HINTS was 100% sensitive and 96% specific, while early MRI missed about 1 in 8 strokes in the first 48 hours (Kattah et al., 2009, Stroke). Those are the ceiling, not the average — the examiners were subspecialists. A later meta-analysis put HINTS at 96.7% sensitivity and 94.8% specificity when specialists ran it, and at 83.3% and 43.8% in the one cohort that was not all subspecialists (Ohle et al., 2020, Academic Emergency Medicine). That gap is what NeuroDash drills.
The claim is scoped to a trained examiner in acute vestibular syndrome — not a promise about any one reader, and never a diagnosis.

The offer

Two ways in. Every term on the table before you pay.

Pro is the subscription. The Mastery Pack beside it is the one-time way in for anyone who would rather not subscribe — the same track, bought once, never a charge on top of Pro. The daily case and every clinical tool stay free whichever you choose, or neither.

Mastery Pack

One payment$79once

A curated path through the cases that decide the dizzy call: gate the syndrome, read the three signs, make the call, and know whether to treat it or refer it.

What the payment buys

  • The six-module Mastery track, yours for good
  • The fluency drill with no daily cap — timed calls, generated fresh
  • The generative trainer with no daily cap
  • The full HINTS ladder and the full encounter
  • Your miss-map, ranked across every sign, and the spaced review built from it

Terms, before you pay

  • One payment of $79. It does not renew, and it is not a subscription. Lifetime access to the six-module Mastery track, including every improvement made to it.
  • Every change to what you bought is published on the What's new page with its date. Improvements reach you automatically — there is no upgrade price and no version you get left on. What is not promised is a cadence, new modules, or a roadmap: this is a commitment to show you every change, not a commitment to ship one every week.

If the price is the problem

Reading the eyes to catch this stroke should not depend on where you practice.

The free core is real, not a demo — the daily case, the eye-sign library, and every clinical tool stay free forever. And if you are a resident or student, or you train somewhere $79 is out of reach, write to us and we will set you up with an access code.
