Week 1 — Neurology Track Research

Companion to “Planning & Questions.md”. Same Week 1/2 framing, neurology lens.


What problem are we solving here?

We’re building an AI that prepares a neurologist for a patient visit — pulling together the prior chart, prior imaging, prior signals, and any longitudinal data into a single pre-visit briefing. The ambient AI scribe market (Abridge, DeepScribe, Nuance DAX) has shown that ambient AI works for note-taking. Our wedge is upstream of the scribe: the briefing the doctor sees before walking into the room.

The neurology version of this is harder than the general medical version because:

  1. The neuro exam is the longest structured exam in medicine (12 cranial nerves, 5 motor, 4 sensory, reflexes, coordination, gait). General scribes collapse it to “neuro exam: grossly intact.”
  2. Localization (symptoms → lesion → differential → workup) is the intellectual core. A normal scribe doesn’t capture it.
  3. Patients have longitudinal signal — MS relapses, Parkinson’s UPDRS drift, seizure frequency, migraine MIDAS — that needs to be trended, not re-typed each visit.
  4. Imaging, EEG, EMG, and labs arrive separately and need to be merged with the note. Scribes only see the transcript; they ignore the rest of the chart.

So the “pre-visit synthesis-for-neuro” wedge has to do three things general scribes don’t:

  • Capture the neuro exam as discrete data, not a paragraph.
  • Combine transcript + prior chart + imaging + EEG reports into one synthesis.
  • Track chronic disease trajectory (EDSS, UPDRS, seizure frequency, MIDAS) over time.

Competitors — AI scribes (overlap (general ambient AI market), but with neuro gaps)

Tier 1 — General scribes used by neurologists today, none of them neuro-specific:

  • DeepScribe — has a specialty module for neurology. Ambient, writes the note into the EHR. Around 500/provider/mo with EHR write-back. Strongest where it’s deployed at health-system scale. Gap: it doesn’t synthesize prior MRI/EEG, doesn’t track EDSS/UPDRS/MIDAS longitudinally.
  • Abridge — Epic-integrated, the de facto scribe at large academic systems. Pricing is contract-only, generally 300+/provider/mo. Gap: same — no imaging/EEG merge, no chronic-disease scoring.
  • Nuance DAX Copilot (Microsoft) — works natively inside Epic/Cerner/athena. ~600+/provider/mo by tier. Gap: even with full EHR access it does not produce a localization narrative; it’s a transcript-to-note engine.
  • Suki — voice-first, 399/provider/mo. Adds voice commands (“order MRI brain,” “schedule EEG”) but still doesn’t surface imaging findings inside the note.
  • Freed79/$119 per provider/mo (the lowest-friction general scribe). Self-serve, no hospital approval needed. Gap: no neuro templates at all — neuro exam collapses to a single sentence.
  • Nabla — free up to 30 encounters/mo, then Pro at $119/mo. Used by small/solo practices. Gap: not specialty-tuned.
  • Heidi Health — Free–$99/mo, multilingual, light templates. No neuro-specific support.
  • DeepCura — newest entrant, claims full neurology templates and model flexibility (lets you switch the underlying LLM per case). $129/mo. Closest direct competitor to a “neuro-specific” scribe — but it still only sees the transcript.

Tier 2 — Neuro-specific or procedure-specific scribes worth knowing about:

  • ScribePT / ScribeLink — niche PT/rehab, not relevant.
  • Medwriter — markets itself to neurologists specifically but is mostly a generic scribe with neuro marketing copy.

What they all share (the gap = our opportunity):

  • Transcript in → note out. They do not ingest the prior chart, prior imaging, prior EEG.
  • No localization reasoning document.
  • No chronic-disease scoring trend.
  • No procedure templates for EMG/NCS, EEG interpretation, lumbar puncture, botulinum toxin.

Competitors — Imaging AI for neuro (heavily more crowded than GI)

This is where neuro diverges from the general scribe market — there are deep, well-funded imaging AI companies already.

  • Viz.ai — LVO (large vessel occlusion) detection on CT/CTA, plus care coordination (notifies the neurointerventionalist on call). Used in 1,700+ hospitals. Recent ESOC data: RapidAI detected 33% more medium-vessel occlusions than Viz.ai — so accuracy gap exists, not just a marketing gap. Door-to-puncture reductions of 11–25 min reported. Pricing: enterprise/contract, no public per-provider number.
  • RapidAI — perfusion (CTP) + LVO detection. Stronger on MeVO and perfusion volumetrics than Viz.ai in head-to-head studies. Enterprise pricing.
  • Brainomix e-Stroke — best-in-class on automated ASPECTS scoring on non-contrast CT. Used in nationwide tenders (Hungary just deployed it across every stroke center). Enterprise pricing.
  • Aidoc — worklist triage + neurovascular algorithms (stroke, hemorrhage, c-spine fracture, aneurysm). Pricing is per-scan via AWS Marketplace: $6/scan for the Starter tier, with enterprise tiers on top. The only public pricing in this space.
  • RapidAI vs. Viz.ai vs. Aidoc vs. Brainomix — scoping review (Medicina, Mar 2026, 29 studies): all four show high LVO sensitivity (78–97%), but performance on distal/posterior circulation varies, and outputs are not interchangeable. 4 of 29 studies were industry-sponsored — bias risk flagged.

Tumor / volumetric AI:

  • Cortechs NeuroQuant + NeuroQuant MS + NeuroQuant Brain Tumor — FDA-cleared volumetric brain MRI. Industry standard for MS lesion/brain atrophy tracking and tumor volumetric reporting. Used in research and increasingly clinical.
  • Cercare Medical “Oncology Virtual Expert” — AI tumor segmentation, 510(k) cleared in 2025.

EEG AI:

  • Ceribell — point-of-care EEG headband + AI seizure detection in the ICU. Fast FDA-cleared deployment, used at Cleveland Clinic and others.
  • Natus autoSCORE AI — AI EEG review as an adjunct to human expert reading.
  • encevis (AIT) — automated EEG analysis (spike/seizure detection), used in European epilepsy centers.
  • Piramidal — newer, scanning a full 24-hour EEG in seconds; Cleveland Clinic collaboration announced 2025.
  • Neuro Event Labs Nelli — long-term ambulatory EEG with AI-assisted seizure detection.

Digital biomarkers / wearables (chronic disease):

  • Empatica EpiMonitor — FDA-cleared wrist-worn seizure detector (generalized tonic-clonic). 15.90–$17.40/mo subscription.
  • Rune Labs StrivePD — Apple Watch-based passive tremor/dyskinesia tracking for Parkinson’s, FDA 510(k) cleared (2023). Free for patients.
  • Multiple companies in MS — using smartphone-based passive tests (Floodlight, MS Performance Test, BeCare MS Link).

What they all share (the gap = our opportunity):

  • Imaging AI ends at the radiology report. It does not write the neuro visit note, does not know what the patient said today, does not surface findings in the encounter.
  • EEG AI is a separate workflow with its own UI. The neurologist still has to read the impression and merge it into the chart manually.
  • Wearables generate streams of biomarker data that nobody puts into the clinic note.

Competitors — Clinical documentation AI (reasoning layer)

  • OpenEvidence — physicians’ #1 most-used clinical AI. Literature-grounded Q&A. Used heavily by neuro for “what’s the latest on X?” but it does not write notes or merge with the chart.
  • UpToDate AI / Wolters Kluwer — guideline lookup, similar pattern.
  • AMBOSS LiSA — clinical reasoning, more accurate than general LLMs on clinical vignettes.
  • Glass Health — generates differential + workup plans from a clinical scenario, used by hospitalists.
  • ChatGPT, Claude, Grok, Perplexity — used informally for drafting patient comms, summarizing guidelines, brainstorming differentials. Physicians report using them weekly but they are not chart-integrated, not HIPAA, not audit-logged.

Pain points — neurologist-specific (from physician surveys and the literature)

The 2025 Physician Sentiment Survey (athenahealth) and the JAMA Network Open AI-summarization study both point the same direction:

  • 65% want documentation/scribing support (highest).
  • 48% want admin burden relief.
  • 43% want clinical decision support.

Neurology-specific amplifications:

  • Neurologic exam adds ~6.7 minutes per visit (study subgroup: pain visits) and is the most failure-prone part of general scribe output (it collapses).
  • MRI results take 1–2 weeks to return in non-academic settings — patients return to clinic with results no one has reviewed with them.
  • EEG impressions are dense, use epilepsy-specific vocab (FREQ, POLY, GTC, interictal discharges, HFO), and take neurologist time to read carefully.
  • Chronic disease scoring is repetitive: EDSS at every MS visit, UPDRS at every PD visit, seizure calendar at every epilepsy visit, MIDAS at every migraine visit — currently re-asked every visit.
  • Documentation is so heavy that neurologists report burnout above the physician-average baseline.

Possible product pathways (parallel to the general scribe product line)

  1. Transcript + scribe specialist — neuro-tuned ambient scribe. (This is what DeepCura and Medwriter are trying to do. Lowest barrier to entry, lowest defensibility.)
  2. Imaging + transcript synthesis — Viz/Aidoc/RapidAI detect the finding, our model writes the clinical correlation and the patient-facing explanation. High defensibility because the radiologist note and the clinic note are separate today.
  3. EEG + transcript synthesis — Ceribell/encevis give the impression, our model merges it with the encounter and proposes med changes. Newer wedge.
  4. Chronic-disease trajectory — ingest prior visits + wearable stream + structured scores, surface “EDSS has drifted +0.5 over 18 months” or “seizure frequency doubled since last visit” before the doctor even opens the chart. (StrivePD / Empatica own the device, but nobody owns the in-clinic surfacing.)
  5. Multimodal model: MRI + EEG + EHR + transcript → differential + workup — biggest defensibility, hardest to ship. This is the “pre-visit synthesis-for-neuro” big vision.

The most realistic Week 1 framing: pick pathway 2 (imaging merge) or pathway 5 (multimodal) as the Big Vision, and use pathway 1 (neuro scribe) as the Week 3 Label Studio demonstrator (it’s the easiest to label and the easiest to evaluate).


Imaging and signal analysis (the AI building blocks, in plain language)

For pictures (MRI, CT, PET):

  • CNNs are the default backbone. ResNets and U-Nets are the workhorses.
  • 3D CNNs and transformer-based U-Nets are the current state-of-the-art for brain tumor and stroke-lesion segmentation (handles volumetric MRI natively).
  • Grad-CAM is the cheapest explainability layer — overlays a heatmap on the MRI showing what the model looked at. Critical for radiologist trust.

For signals (EEG, EMG):

  • 1D CNNs + BiLSTM hybrid is the standard architecture (Frontiers in Neurology 2025 review).
  • CNN-RF hybrid and FCNLSTM show 95–99% accuracy on Bonn/CHB-MIT benchmarks but most haven’t been validated in clinical EEG (different preprocessing, different artifact profile).
  • Dynamic Graph Neural Networks are newer; 99.83% on Bonn single-channel.

For multimodal:

  • EEG + sMRI/fMRI fusion with attention mechanisms has reported up to ~99% diagnostic accuracy on Parkinson’s in some studies (MDPI 2024). Caution: most published numbers are on small datasets; generalization is the open question.
  • Visual Question Answering (VQA)-style multimodal networks are the closest published architecture to “ask the MRI a question and get an answer in natural language.” Worth tracking for the prototype.

For structured EHR data:

  • XGBoost / Random Forests on longitudinal EHR features for disease-conversion prediction (e.g., mild cognitive impairment → Alzheimer’s). Used in pharma-trial enrichment.

For wearables:

  • Apple Watch Movement Disorders API (tremor, dyskinesia) → StrivePD pipeline.
  • Empatica EDA + accelerometer → generalized tonic-clonic seizure classifier.

Strategy — where this puts us in the broader AI strategy landscape

The ambient AI scribe market’s Week 1 gaps (the parallel track the team is using for reference): competitor pricing is spread across 600, and no single vendor combines transcript + chart + imaging + signals into a pre-visit synthesis.

Neurology’s Week 1 gaps are sharper but the playbook is the same:

  • Scribe market is more crowded on price (down to $39/mo with Freed).
  • Imaging AI is more crowded and deeper (Viz/RapidAI/Brainomix/Aidoc all clinically deployed).
  • EEG AI is fragmented (Ceribell, Natus, encevis, Piramidal — none dominant).
  • Wearables are device-side only (StrivePD, EpiMonitor) — no one owns the in-clinic surfacing.

Our wedge = the missing layer between “transcript,” “prior chart,” “MRI/CT,” “EEG/EMG,” and “the actual visit note.” For neurology the modality surface is wider (imaging + signals + EHR + transcript), and the longitudinal chronic-disease trajectory is a unique layer that no scribe owns.


Open questions for week 2 (your three questions, neurology angle)

  1. Do we go after the neuro-scribe wedge (low risk, low defensibility) or the imaging-merge wedge (higher risk, much higher defensibility)? This determines which datasets we prioritize in Week 3.
  2. Is the deliverable a working prototype or a blueprint? For neuro, a blueprint is more realistic given the imaging/signal complexity.
  3. What “big vision” framing matches pre-visit synthesis’s? Candidates:
    • “The neuro consult, fully reconstructed from chart + imaging + EEG + transcript.”
    • “Localization, automated: symptoms → lesion → workup, drafted before the neurologist enters the room.”
    • “The chronic-neurology dashboard: MS, Parkinson’s, epilepsy, migraine — trended across every visit, surfaced in the note.”
