Clinical note · The bedside eye exam
Read the eyes.
Make the call.
Unidirectional horizontal · abnormal head impulse · damped by fixation
Inner ear, or the brain?
Make the call — then see the reasoning. No sign-up.
The dizzy patient you cannot afford to misread is the one whose inner-ear story is hiding a stroke. The eyes are what tell them apart. Make that call here first, on a new patient every time.

Only here
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: generated from the physics, the answer derived from the same math that draws the eyes.
Three 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 double vision, no weakness, no slurred speech.
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?
Stylised teaching animation from a physics engine — not a real-patient recording, not a diagnosis.
The drill
Reading about the exam is not the same as making the call.
NeuroDash gives you the reps: a new dizzy patient every time, generated live. You decide inner ear or stroke, then see the reasoning — case after case, not a fixed set of clips to watch once.
- 01
Gate the syndrome
HINTS applies only to the acute vestibular syndrome — dizzy right now, continuously. The gate comes first, on the TiTrATE framework (Newman-Toker & Edlow, 2015).
- 02
Read the eyes
Head impulse, nystagmus, test of skew — rendered from parameters, not filmed. Read the finding the way you would at the bedside.
- 03
Make the call
Inner ear or stroke. You commit before the rationale — retrieval practice, cited on the trust page, not a passive re-read.
- 04
See the reasoning
The INFARCT logic, laid against the finding you just read. Then the next patient, weighted toward the signs you miss.
Why the eyes
Why this call is worth drilling.
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.

Pro checkout is unavailable right now
The daily case stays free either way, and every free allowance above is unchanged.
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 the Mastery Pack — checkout is not open right now, so neither can be bought at the moment.
Disclosure
It supports your judgment. It never replaces it.
Cited, not asserted
Every answer names the guideline it comes from. Kattah 2009 for HINTS, the Bárány Society and AAO-HNS for the rest.
Stylised teaching
The animations are rendered from physics and exaggerated for visibility. Never a recording of a real patient, and never diagnostic.
