LANDMARK TRIALS

  • Know the studies that changed when—and where—we operate
  • THE EVIDENCE TIMELINE
  • 2006 — GPi dystonia — Sham-controlled: significant motor improvement
  • 2008–10 — CSP 468 / COMPARE — STN vs GPi: target-specific trade-offs
  • 2013 — EARLYSTIM — Earlier STN DBS improved QoL vs medical therapy
  • 2016 — NSTAPS 3-y — STN: greater off-motor improvement; more medication reduction
  • 2019 — VIM long-term — Benefit persists, but habituation / disease progression matter
  • 2024 — VIM vs PSA RCT — Comparable tremor reduction; PSA lower intensity + selected advantages
  • Teaching point: trials define probabilities and trade-offs; they do not replace phenotype-based target selection.

Central message

The value of DBS expertise is not memorizing targets. It is making the right decision for the right patient at the right time.

Expanded study material

Cases, evidence and pearls

Supplementary material written around the immutable original slides 46–50.

Interactive case

Case 1 — the perfect lead that didn't work

Vote first, discuss second. The vote is the teaching device, not an examination.

Audience vote — Case 1

What do you check first?

Programming problem or anatomy problem?

If the lead is well positioned

  • Contact selection
  • Amplitude
  • Pulse width
  • Frequency
  • Configuration
  • Directional steering
  • Medication interaction

If the lead is poorly positioned

  • Available therapeutic field
  • Adjacent structures
  • Alternative contacts
  • Realistic programming limits
  • Revision only if appropriate

Localize before you revise.

Interactive case

Case 2 — STN or GPi?

A target-selection case in which the stated goals do the work.

Audience vote — Case 2

STN or GPi? Defend your choice in one sentence.

Interactive case

Case 3 — tremor: VIM or PSA?

Nucleus and pathway are complementary concepts, not competing brands.

VIM — established

  • Long clinical experience
  • Strong evidence base
  • Familiar surgical target
  • Established programming framework
  • Considerations: speech, paresthesia, gait, habituation

PSA / DRTT — pathway-aware

  • Pathway-based targeting
  • Lower stimulation intensity in selected studies
  • Selected head tremor / QoL advantages in some data
  • Challenges: anatomical variability, trajectory precision, smaller long-term evidence base

  2. 02SUPERIOR CEREBELLAR PEDUNCLE
  3. 03DECUSSATION
  4. 04DRTT
  5. 05THALAMIC REGION
  6. 06MOTOR NETWORK

Place the lead, the modelled field and the pathway together and ask: where is the therapeutic contact relative to the DRTT? Tractography renders a model of probable pathways — it does not visualize axons.

The best target is not the most fashionable target. It is the target that best matches the patient, anatomy, pathway and therapeutic objective.

Master simulator

The DBS decision simulator

Ten steps around a fictional patient. Every step asks what information would change the decision.

What information changes your decision?

Is the diagnosis secure, and what would change it?

Atypical features, an unusual course or an unconvincing medication history all reopen the diagnosis before any target is discussed.

The simulator teaches reasoning, not right and wrong answers. The patient is fictional; no real clinical data are used.

Landmark evidence library

The evidence wall

Each trial is read as population, target, question, outcome, limitation and clinical implication. Trials are not interchangeable.

Population
Selected patients with primary generalized or segmental dystonia
Target
GPi
Question
Does GPi stimulation produce genuine benefit beyond sham / placebo effects?
Main finding
Significant motor improvement, including in a sham-controlled design
Key limitation
Selected dystonia populations; benefit varies by aetiology and phenotype
Clinical takeaway
GPi DBS is a recognized option in appropriately selected primary dystonia — not in all dystonia.

Trials inform the decision. The surgeon still has to make the decision.

DBS — from coordinates to precision neuromodulation

50 SLIDES · 10 MODULES · 1 CONTINUOUS DBS JOURNEY

PATIENT → TARGET → TRAJECTORY → LEAD → FIELD → PROGRAMMING → NETWORK → FOLLOW-UP → OUTCOME

DBS is not a device implant. It is a long-term clinical system.

The operation is implantation. The treatment is lifelong.

Precision neuromodulation, delivered through a lifetime of decisions.

Deep study material

Expanded study material

DBS is effective in appropriately selected patients with Parkinson disease, essential tremor and dystonia

ESTABLISHED

Randomized evidence supports motor benefit and quality-of-life benefit in defined populations. Selection and target choice remain clinical decisions.

STN and GPi both produce motor benefit with target-specific trade-offs

ESTABLISHED

Randomized comparisons describe differences in medication reduction, dyskinesia strategy and composite cognitive, mood and behavioural measures rather than one universally superior nucleus.

Lead localization matters in unexplained poor response

SUPPORTED

Registration of postoperative imaging to preoperative MRI with reconstruction of the implanted lead is the accepted way to establish where the lead actually is before revision is discussed.

Pathway-aware tremor targeting

SUPPORTED

PSA / DRTT-oriented targeting can achieve tremor control at lower stimulation intensity in selected studies; the evidence base remains smaller than for VIM and does not replace it.

Model-based failure analysis

EMERGING

Combined lead reconstruction, VTA modelling and connectomic analysis of DBS outcome is an active research area rather than routine care.

Automated target recommendation and individualized outcome prediction

EXPERIMENTAL

RESEARCH DIRECTION — not clinical practice, and not a substitute for the clinical decision.

DBS IS A SYSTEM, NOT A PROCEDURE.

Clinical pearls

  • Selection is the first operation.
  • The target follows the phenotype.
  • The coordinate is not the biological target.
  • Trajectory planning is target planning.
  • MER confirms physiology; it does not replace anatomy.
  • Reconstruct the implanted lead.
  • Program for the therapeutic window, not maximal effect.
  • Directional DBS shapes the field.
  • Poor response requires localization before revision.
  • DBS is a lifelong treatment journey.

Common errors

  • Treating “good postoperative coordinates” as proof of a good therapeutic lead.
  • Reprogramming repeatedly instead of localizing the failure.
  • Reading EARLYSTIM as an instruction to operate early on everyone.
  • Declaring STN universally superior — or GPi universally safer.
  • Converting a small crossover trial into “PSA is better than VIM”.
  • Quoting a trial result without its population, outcome measure and limitation.
  • Choosing a target before the therapeutic goal has been agreed.
  • Presenting tractography as visualization of axons.
  • Using revision as a troubleshooting step rather than a diagnostic conclusion.
  • Ending care at the programming session instead of planning the lifelong journey.

Case discussion

Cases

Case discussion

CASE 1 — “The perfect lead that didn't work”

Patient profile

Teaching case as presented on original slide 46. No real patient data are used.

Clinical phenotype

62 years · STN DBS · excellent initial imaging · minimal benefit.

Surgical plan

Audience vote — what do you check first? A programming · B lead reconstruction · C diagnosis / phenotype · D medication response · E hardware integrity.

Outcome

THIS IS A LOCALIZATION PROBLEM. Work the sequence: diagnosis → phenotype → lead → hardware → programming → medication → disease progression.

Audience vote

WHAT DO YOU CHECK FIRST?

  • AA — Programming settings
  • BB — Lead reconstruction
  • CC — Diagnosis / phenotype
  • DD — Medication response
  • EE — Hardware integrity

Lessons

  • Do not assume good postoperative coordinates equal a good therapeutic lead.
  • Reconstruct, localize and troubleshoot before revision.
  • Revision follows a localizable, correctable problem — never a frustration.

Case discussion

CASE 2 — STN or GPi?

Patient profile

Teaching case as presented on original slide 48. No real patient data are used.

Clinical phenotype

Parkinson disease · motor fluctuations · troublesome dyskinesia · cognitive concern · medication reduction not the main goal.

Surgical plan

Audience vote — STN or GPi? Defend your choice in one sentence.

Outcome

GPi MAY be favored by the stated goals and concerns, but the final decision remains individualized. Target follows phenotype and therapeutic goal.

Target options
  • STN
  • GPi

Audience vote

STN or GPi?

  • ASTN
  • BGPi

Lessons

  • Name the therapeutic goal before naming the nucleus.
  • Cognitive concern is a consideration, not an automatic exclusion.
  • Ask what information would flip the decision — that is the examination.

Case discussion

CASE 3 — Tremor: VIM or PSA?

Patient profile

Teaching case as presented on original slide 49. No real patient data are used.

Clinical phenotype

Medication-refractory severe tremor + head tremor + speech concern.

Surgical plan

Where is the therapeutic contact relative to the DRTT?

Outcome

The best target is the one that best matches the patient, anatomy, pathway and therapeutic objective — not the most fashionable one.

Target options
  • VIM
  • PSA / DRTT

Audience vote

VIM or PSA / DRTT?

  • AVIM
  • BPSA / DRTT

Lessons

  • VIM is a nucleus; DRTT is a pathway concept. Keep them distinct.
  • Comparable tremor reduction at lower intensity is not the same as superiority.
  • Speech concern belongs in the targeting decision.

Case discussion

FINAL CASE — What would you do?

Patient profile

Integrated teaching case. No real patient data are used.

Clinical phenotype

Parkinson disease · motor fluctuations · dyskinesia · cognitive concern · medication reduction not the primary goal.

Surgical plan

Ten questions: STN or GPi? What imaging would you review? What trajectory constraints matter? Would you use MER? How would you verify final lead position? What would you program first? What would make you suspect a poor lead? When would you revise? What would you monitor longitudinally? What is the patient's actual treatment goal?

Outcome

There is no single correct answer. The faculty framework is the answer: goal → phenotype → target → trajectory → physiology → verification → field → programming → follow-up.

Lessons

  • Every question is answerable only in relation to the stated therapeutic goal.
  • Verification and follow-up are part of the surgical plan, not aftercare.
  • A defensible reasoning chain matters more than a preferred nucleus.

Take-home message

The operation is implantation. The treatment is lifelong.Trials inform the decision. The surgeon still has to make the decision.
