Read the eyes.
Make the call.

Walk into the dizzy bay 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.

Two patients. One story. One finding apart.

A video shows you one patient. It cannot show you the same patient with a normal reflex instead of an abnormal one — that patient does not exist. Ours does: run the head impulse on both, make the call, then decide whether it is worth paying for.

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).

Generated live · answer derived from the physics

One day of continuous dizziness, present now at rest and worse with any head movement. There was no trigger and no head movement at onset. 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 stroke?

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.

Figure 1. Two patients, the same history, one HINTS finding apart. The correct call is derived from the same kinematics that draw the eyes, so the animation and the label cannot drift apart. Stylised teaching, exaggerated for visibility; not a recording of a patient. After Kattah et al., 2009 (Stroke).

That pair was generated when this page loaded. The Pack is the same engine, sequenced into six modules.

Who it is for

Built for the clinician who wants to get sharp at one decision: is this dizzy patient’s problem the inner ear or the brainstem? If you would rather drill that call than read another mnemonic, this is the path.

The contents

See exactly what you are buying.

A curated path through the cases that decide the dizzy call: gate the syndrome, read the three signs, make the call, and carry it to a disposition.

Figure 2 · Contents6 modules

  1. Reading the eye movements

    Learn what each bedside eye sign looks like and where it points — the vocabulary the rest of the track is built on.

  2. Posterior-canal BPPV

    Recognise the up-beating torsional burst of the commonest positional vertigo — and why HINTS does not belong here.

  3. Horizontal-canal BPPV

    Read the direction-changing horizontal beat of the supine roll test, and the maneuvers that are not the Epley.

  4. Anterior-canal and the central positional mimics

    Separate rare anterior- (superior-) canal BPPV — a benign canalithiasis repositioned with a non-Epley maneuver — and the central positional mimics from common posterior-canal BPPV. The central beats (pure downbeat, no latency, non-fatiguing) are the ones a repositioning maneuver must not be used on.

  5. Acute vestibular syndrome: HINTS

    Run HINTS on the patient dizzy right now — head impulse, nystagmus, skew — and read central from peripheral.

  6. Mixed mastery drills

    Put it together: unprompted mixed cases, then the ED call, where the disposition carries a consequence.

Figure 2. The Pack is a sequence over cases NeuroDash already teaches — no new content, just the order that builds from “what does this beat look like” to the call under time. Every module is worked in the trainer you can open now.

What you can do at the end of it

  • Gate the syndrome before you run HINTS
  • Read the head impulse for a corrective saccade
  • Tell central nystagmus from peripheral
  • Catch the skew that points to the brainstem
  • Make the central-versus-peripheral call under time
  • Carry the call to a disposition — image, admit, or send home

One payment of $79. It does not renew, and it is not a subscription. Lifetime access to the six-module Mastery track. 14-day money-back guarantee, no questions asked.

Your access is tied to the email you check out with. Pay with your email — no account to set up first — and access is sent to that address.

Pro already includes the Mastery track. The Pack is the one-time way in for anyone who would rather not subscribe — the same track, bought once, not a charge on top of Pro. See Pro.

Checkout is not open right now, so the Pack cannot be bought at the moment. If you bought it before, sign in with that email and it is still yours.

Why the Pack

One payment, not a subscription, and the track is yours for good. It is depth on a single call — is this dizzy patient’s problem the inner ear or the brainstem — not a broad course. It costs far less than an accredited CME course, and it is honest about being a different thing: not accredited, not CME credit, and not physician-reviewed. What you get is the practice, and a record of it — not a credential.

At the end

Your completion record

Finish all six modules and your completion record is issued here — a personal record of the practice you have done, not a credential.

A personal record of practice completed on this device. Education, not CME/CE credit, not a license, not board certification. It does not authorize independent clinical practice.

Disclosure
The Mastery track sequences NeuroDash's stylised teaching cases and eye-sign animations, based on the HINTS exam (Kattah 2009) and the AAO-HNS BPPV guideline (Bhattacharyya 2017). Authored in-house and not reviewed by an outside specialist. Educational only — not medical advice, not a diagnosis, and not a clinical credential.
