Questions to Ask a Neurology Expert Witness at Deposition (2026 Guide)

By John Mahoney · Updated 2026-09-01 · 18 questions in 4 concession chains

You are about to cross-examine someone with two decades of training you don't have, on their home turf, about the thing they do every day. That asymmetry is the defining problem of medical-expert depositions — and it gets worse in multi-defendant malpractice cases, where two to four different specialties can be in play in a single case and you have to be conversant in all of them by deposition day.

Neurology experts appear in stroke cases, missed-deficit cases, and as causation witnesses on permanent neurological injury. Stroke litigation is fundamentally about time, and the profession’s own "time is brain" teaching is a concession no neurologist can walk away from.

The answer to the asymmetry is not to learn neurology — it is structure. A concession funnel asks the expert to agree, one fact at a time, to propositions so orthodox that refusing them costs more credibility than granting them. The questions below are a generic-case-safe starting bank, organized into the four chains that structure works through.

How to use these questions

Every question below follows three rules of expert cross-examination: it is leading (it states a fact and asks for agreement), it contains one fact (no compounds — a compound question lets the witness answer the easy half), and it belongs to a concession chain (each answer narrows the room the next answer can live in). Ask them in order. When you get the concession, stop — do not ask the "why" question that lets the expert explain it away.

Chain 1 — Qualifications, retention & scope

Goal: establish on the record that this is a paid, retained witness who never touched the patient, and fix the boundaries of what they actually practice.

Doctor, you were retained by opposing counsel in this case, correct?
You are being compensated for your time reviewing this case and for your testimony today, correct?
You never examined or treated the patient in this case, correct?
Everything you know about this case comes from the materials counsel selected and sent to you, correct?
You agree that the treatment of acute stroke has changed substantially over your career — and that currency in that literature matters for opinions about it, correct?

Chain 2 — Bases-of-opinion lockdown

Goal: freeze the universe. After this chain, any new document, new basis, or new opinion at trial is impeachment material.

You have now told us every document and material you reviewed in forming your opinions, correct?
You are not relying on anything outside that file for the opinions you will give in this case, correct?
You have told us every opinion you intend to offer at trial, correct?
You agree that an opinion you cannot state to a reasonable degree of medical probability is speculation, correct?

Chain 3 — Substantive concessions: stroke timing and the neurological exam

The chain below establishes the two pillars of most neurology cases: acute stroke care is time-critical, and neurological deficits are found by examining the patient. Every question is orthodox neurology.

In ischemic stroke, earlier treatment is associated with better outcomes, correct?
Some treatments for ischemic stroke are only available within a limited time window, correct?
That is why the time a stroke is recognized matters, correct?
A neurological examination is how deficits are identified and tracked, correct?
New or worsening neurological deficits require prompt evaluation, correct?
The imaging in this case is objective data, correct?

Chain 4 — Closing the doors

Goal: end with the record sealed. These questions convert silence into a commitment that nothing new is coming at trial.

You are not offering any opinions in this case beyond the ones we have discussed today, correct?
You have not held back any opinion or criticism that you intend to offer at trial, correct?
You are not offering any opinion about the emergency-department triage process in this case, correct?

These are the generic questions. Your case isn't generic.

Where lawyers get burned deposing neurology experts

Letting the expert time-shift symptom onset

Everything in a stroke case hangs on the onset clock. Experts move it — "the deficit likely began earlier than charted" — to close the treatment window. Lock every documented time and every source for it before any discussion of eligibility for treatment. Make the expert choose their timeline under oath, once.

Accepting "the outcome would have been the same" without a committed timeline

Causation opinions in stroke cases are only as good as the timeline they assume. An expert who has not committed to specific times is free to assume whatever defeats causation. Timeline first; only then ask the would-it-have-mattered questions.

Conflating a completed stroke with an evolving one

Defense experts describe the injury as complete on arrival. Separate the questions: what was the deficit at each documented exam, and what changed between exams. Documented worsening between exams is the evolving process the defense theme denies.

FAQ

What questions should I ask a neurology expert witness at deposition?

Work in four concession chains: (1) qualifications, retention, and scope — establish the expert was retained, is compensated, never treated the patient, and what they do and do not practice; (2) bases-of-opinion lockdown — pin every document reviewed and every opinion they intend to offer; (3) the neurology-specific substantive chain — well-established propositions such as "In ischemic stroke, earlier treatment is associated with better outcomes"; and (4) closing the doors — confirm on the record that no undisclosed opinions remain. Every question should be leading, contain one fact, and build on the prior answer.

How do I cross-examine a medical expert when I never went to medical school?

You don't out-doctor the doctor — you build concession chains from propositions so well-established that a credible neurology expert cannot refuse them, then apply those concessions to the facts in the chart. The expert's medical training becomes your asset: the more orthodox the proposition, the more it costs them to fight it. The asymmetry problem is real — especially in multi-defendant cases with two to four specialties — which is why the questions are organized as funnels rather than as debates.

What are the biggest traps when deposing a neurology expert witness?

The classic traps are letting the expert shift the symptom-onset clock to close the treatment window, accepting a "same outcome anyway" causation opinion before the expert has committed to a specific timeline, and letting a documented evolving deficit be described as a completed stroke.
