The ABPN Neurocritical Care subspecialty exam is 270 one-best-answer MCQs in five 54-question sections, with 320 minutes of scheduled testing time plus up to 40 minutes of optional pooled breaks, at Pearson VUE. It is offered every other year in even-numbered years (2026 exam Oct 5-9; next in 2028). The ABPN Content Specifications define five domains: Principles of neurocritical care (42-48%), Diagnostic studies and procedural skills (13-17%), Neurocritical care diseases (27-33%), Neurosurgical and perioperative complications (3-7%), and Ethics, research, and practice-based learning (3-7%). The exam fee is $1,900 (+$500 if late). It requires primary ABMS certification plus, after the 2026 administration, either 1 year of critical care fellowship plus 1 year of NCC fellowship, or 2 years of NCC fellowship (the practice pathway covered only the 2021-2026 exams). ABPN reports 91% (2021), 94% (2022), and 96% (2024) first-time pass rates for ABPN examinees, and states there is currently no limit on the number of times an applicant may apply.

Sample ABPN Neurocritical Care Practice Questions

Try these sample questions to review concepts for the ABPN Neurocritical Care exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1According to the Brain Trauma Foundation 4th edition guidelines, what intracranial pressure (ICP) threshold should trigger treatment in adults with severe traumatic brain injury?
A.ICP > 15 mm Hg
B.ICP > 20 mm Hg
C.ICP > 22 mm Hg
D.ICP > 30 mm Hg
Explanation: The BTF 4th edition (2016) raised the ICP treatment threshold from >20 to >22 mm Hg based on observational data showing increased mortality above this level. Sustained ICP >22 mm Hg requires escalating tiered therapy (sedation, hyperosmolar therapy, CSF drainage, decompressive craniectomy).
2What is the recommended cerebral perfusion pressure (CPP) target range in severe TBI per the Brain Trauma Foundation guidelines?
A.40-50 mm Hg
B.50-60 mm Hg
C.60-70 mm Hg
D.80-90 mm Hg
Explanation: BTF recommends CPP 60-70 mm Hg. CPP <60 risks ischemia; CPP >70 maintained with vasopressors increases ARDS risk. CPP = MAP − ICP, so CPP optimization requires both MAP support and ICP control.
3A 55-year-old man with severe TBI has ICP of 28 mm Hg despite head-of-bed elevation, sedation, and analgesia. Which next-tier intervention is most appropriate?
A.IV mannitol 0.25-1 g/kg or 3% saline 250 mL bolus
B.IV dexamethasone 10 mg
C.IV furosemide 40 mg
D.Hyperventilation to PaCO2 of 25 mm Hg sustained
Explanation: After initial measures fail, hyperosmolar therapy (mannitol or hypertonic saline) is the next step. Steroids are CONTRAINDICATED in TBI (CRASH 2004 — increased mortality). Aggressive hyperventilation (PaCO2 <30) causes excessive vasoconstriction and ischemia and should be avoided as a sustained therapy.
4Which serum laboratory threshold should prompt holding additional mannitol doses to prevent acute kidney injury and osmolar gap toxicity?
A.Serum osmolality > 280 mOsm/kg
B.Serum osmolality > 320 mOsm/kg or osmolar gap > 20
C.Serum sodium > 140 mEq/L
D.Serum creatinine > 1.5 mg/dL
Explanation: Mannitol is held when serum osmolality exceeds 320 mOsm/kg or the osmolar gap exceeds 20 mOsm/kg, since further dosing risks AKI from intratubular accumulation and indicates tissue saturation.
5A patient with severe TBI develops refractory ICP elevation despite Tier 2 measures. The RESCUEicp trial (2016) demonstrated which outcome with secondary decompressive craniectomy?
A.Reduced 6-month mortality but increased proportion of vegetative or severely disabled survivors
B.Reduced mortality and improved functional outcome
C.No difference in mortality or function
D.Increased mortality
Explanation: RESCUEicp (Hutchinson et al., NEJM 2016) showed that decompressive craniectomy for refractory raised ICP reduced 6-month mortality but at the cost of more vegetative state and severe disability among survivors. DECRA (2011) earlier showed no benefit and possible harm with EARLY bifrontal decompression.
6What is the recommended PaCO2 range for brief therapeutic hyperventilation as a bridging measure for acutely elevated ICP?
A.PaCO2 25-30 mm Hg
B.PaCO2 30-35 mm Hg
C.PaCO2 35-40 mm Hg
D.PaCO2 40-45 mm Hg
Explanation: Brief hyperventilation to PaCO2 30-35 mm Hg can transiently reduce ICP via cerebral vasoconstriction. PaCO2 <30 risks excessive vasoconstriction and ischemia, especially in the early hours after TBI when CBF is already reduced.
7Severe TBI with GCS ≤8 and which CT finding should prompt invasive ICP monitoring per BTF guidelines?
A.Any abnormal CT finding (hematoma, contusion, swelling, herniation, compressed cisterns)
B.Only midline shift > 5 mm
C.Only basal cistern effacement
D.Only diffuse axonal injury
Explanation: BTF recommends ICP monitoring in all salvageable patients with severe TBI (GCS 3-8 after resuscitation) and an abnormal CT scan, including hematoma, contusion, swelling, herniation, or compressed basal cisterns.
8Which type of intracranial pressure monitor permits both continuous ICP measurement AND therapeutic CSF drainage?
A.Intraparenchymal probe (Camino, Codman)
B.External ventricular drain (EVD/ventriculostomy)
C.Subdural bolt
D.Epidural fiberoptic probe
Explanation: An external ventricular drain placed in the lateral ventricle allows continuous ICP monitoring AND can drain CSF to lower ICP. It can also be re-zeroed externally. Intraparenchymal probes provide accurate measurement but cannot drain CSF and cannot be re-zeroed once placed.
9In a patient with malignant MCA infarction and midline shift, decompressive hemicraniectomy demonstrates the greatest mortality and functional benefit when performed within what time window?
A.Within 6 hours
B.Within 24 hours
C.Within 48 hours
D.Within 72 hours
Explanation: Pooled analysis of DESTINY, HAMLET, and DECIMAL showed decompressive hemicraniectomy within 48 hours of stroke onset reduced mortality (NNT 2) and improved functional outcome (NNT 4 for mRS ≤4) in malignant MCA infarction, particularly in patients <60 years old.
10What is the correct dose of IV alteplase for acute ischemic stroke within 4.5 hours of last known well?
A.0.6 mg/kg, max 60 mg
B.0.9 mg/kg, max 90 mg (10% bolus, 90% over 60 min)
C.1.0 mg/kg, max 100 mg over 30 min
D.0.25 mg/kg single bolus
Explanation: Standard IV alteplase for ischemic stroke is 0.9 mg/kg (max 90 mg) given as 10% bolus over 1 minute and the remaining 90% as an infusion over 60 minutes. Tenecteplase 0.25 mg/kg as a single bolus is increasingly used as an alternative.

About the ABPN Neurocritical Care Exam

The ABPN Neurocritical Care Subspecialty Certification Examination is jointly developed by ABA, ABEM, ABIM, ABNS, and ABPN, and administered by ABPN in five 54-question sections (270 questions total) at Pearson VUE to eligible diplomates of all five boards at the same sitting. The subspecialty was ABMS-approved in 2018 (UCNS has offered a separate, non-ABMS NCC certification since 2007); the first ABPN-administered exam was given in 2021, and it is now offered every other year in even-numbered years (2026 exam Oct 5-9; next in 2028). Candidates need primary ABMS certification (Neurology, Neurosurgery, Anesthesiology, Internal Medicine, or Emergency Medicine); after the 2026 administration, most candidates need either 1 year of general ACGME-accredited critical care fellowship plus 1 year of ACGME-accredited neurocritical care fellowship, or 2 years of ACGME-accredited neurocritical care fellowship (the practice pathway covered only the 2021-2026 exams). The exam covers acute ischemic stroke and reperfusion therapy, large vessel occlusion endovascular thrombectomy, spontaneous and traumatic intracranial hemorrhage, aneurysmal subarachnoid hemorrhage and delayed cerebral ischemia, traumatic brain injury and Brain Trauma Foundation 4th-edition guidelines, intracranial pressure and cerebral perfusion pressure management, refractory and super-refractory status epilepticus (ESETT staged algorithm), brain death determination per the AAN/AAP/CNS/SCCM 2023 consensus, multimodal neuromonitoring (ICP, EEG, PbtO2, microdialysis), targeted temperature management and post-cardiac arrest neuroprognostication, neuromuscular respiratory failure (myasthenic crisis, GBS), neurosurgical and spinal cord emergencies, and sedation/analgesia/pharmacology in the NeuroICU.

ABPN Neurocritical Care: Suggested Study Strategy

1ICP/CPP targets (Brain Trauma Foundation 4th ed): Treat ICP >22 mm Hg. Maintain CPP 60-70 mm Hg — avoid CPP <60 (worsens ischemia) AND avoid CPP >70 with vasopressors (causes ARDS). Tiered escalation: head-of-bed 30°, normothermia, sedation → 3% saline 250 mL bolus or mannitol 0.25-1 g/kg (monitor sodium, renal function, and the osmolar gap; NCS 2020 finds no evidence for fixed 320 mOsm/kg or gap-20 cutoffs) → CSF drainage via EVD → brief hyperventilation PaCO2 30-35 (bridging only — vasoconstriction reduces CBF) → decompressive craniectomy (RESCUEicp 2016: survival benefit but more vegetative outcomes; DECRA 2011 negative for early bifrontal). Avoid steroids (CRASH 2004: increased TBI mortality) and hypotonic fluids.
2ESETT-staged status epilepticus (AES 2016 phases): Initial therapy (5-20 min) — IV lorazepam 0.1 mg/kg (max 4 mg) or IM midazolam 10 mg if no IV (RAMPART). Second therapy (20-40 min, established SE) — IV fosphenytoin 20 mg PE/kg, levetiracetam 60 mg/kg (max 4500), or valproate 40 mg/kg (max 3000) — ESETT 2019 showed all three roughly equipotent (~46% efficacy). Third therapy (40-60 min, refractory SE) — continuous midazolam (0.2 mg/kg load then 0.05-2 mg/kg/h), propofol (watch PRIS >4 mg/kg/h or >48 h), or pentobarbital titrated by cEEG to seizure suppression or burst suppression. Super-refractory SE (>24 h) — ketamine, inhaled anesthetics, hypothermia, immunotherapy if NORSE/FIRES.
3AAN/AAP/CNS/SCCM 2023 brain death determination: Prerequisites — irreversible catastrophic injury with known etiology, core temp ≥36 °C, SBP ≥100 mm Hg and MAP ≥75 mm Hg (adults), no sedatives/paralytics/severe metabolic-endocrine confounders. Exam — coma, absent brainstem reflexes (pupils, corneal, oculocephalic, oculovestibular cold caloric, gag, cough), no motor response (spinal reflexes allowed). Apnea test — the guideline requires ALL THREE of: no respirations occur, arterial pH <7.30, AND PaCO2 ≥60 mm Hg AND ≥20 mm Hg above the patient's preapnea baseline (not 'either/or'). Ancillary testing only if the exam or apnea test cannot be completed: 4-vessel catheter angiography, radionuclide perfusion scintigraphy, or TCD (adults only); EEG, evoked potentials, CTA, and MRA are not acceptable (2023 guideline). 2023 update: ONE exam in adults; pediatrics still requires TWO exams with age-based interval.
4Aneurysmal SAH management pearls: Secure the aneurysm as early as feasible, preferably within 24 hours (2023 AHA/ASA, COR 1), by coiling or clipping (ISAT 2002 — coiling better at 1 yr in amenable lesions). Nimodipine 60 mg PO q4h × 21 days improves outcome by preventing DCI — neuroprotective effect, NOT prevention of angiographic vasospasm. Vasospasm peaks days 4-14. Monitor with TCD: mean MCA velocity >120 cm/s suspicious, >200 cm/s severe; Lindegaard ratio MCA/ICA >3 distinguishes vasospasm from hyperemia. Treat symptomatic DCI with PERMISSIVE/induced hypertension (triple-H abandoned), intra-arterial vasodilators, balloon angioplasty. EVD for acute hydrocephalus. Hyponatremia: distinguish cerebral salt wasting (hypovolemic) from SIADH (euvolemic), but avoid fluid restriction after aSAH in either case; maintain euvolemia and use hypertonic saline or fludrocortisone as needed.
5Post-cardiac arrest care and neuroprognostication: TTM2 (2021) — targeting 33 °C did not reduce 6-month mortality versus normothermia with early fever treatment (≤37.5 °C) in OHCA of presumed cardiac or unknown cause, across initial rhythms. The 2025 AHA post-cardiac arrest guideline recommends a target temperature of 32-37.5 °C (Class 1), maintained for at least 36 hours (Class 2a), with strict fever avoidance. Multimodal neuroprognostication ≥72 h after ROSC (or ≥72 h after rewarming) — combine MULTIPLE indicators: bilaterally absent N20 SSEP, absent pupillary/corneal reflexes at 72 h, status myoclonus <72 h, NSE >60 mcg/L at 48-72 h, malignant EEG (suppression, burst-suppression with identical bursts, status on flat background), diffuse cortical/deep gray DWI restriction, loss of gray-white on CT. NEVER prognosticate <72 h or with confounders (sedation, hypothermia, paralytics).

Frequently Asked Questions

What is the ABPN Neurocritical Care Subspecialty Examination?

The ABPN Neurocritical Care Subspecialty Certification Examination is jointly developed by ABA, ABEM, ABIM, ABNS, and ABPN, and administered by ABPN at Pearson VUE test centers to eligible diplomates of all five boards at the same sitting. It certifies expertise in the management of critically ill patients with primary or secondary neurologic injury — including acute ischemic and hemorrhagic stroke, aneurysmal subarachnoid hemorrhage, traumatic brain injury, status epilepticus, brain death determination, post-cardiac arrest care, neuromuscular respiratory failure, and multimodal neuromonitoring. UCNS has certified NCC physicians since 2007 as a separate, non-ABMS credential; ABMS approved the ABPN-administered subspecialty in 2018, and the first ABPN-administered exam was given in 2021.

Who is eligible to sit for the Neurocritical Care subspecialty exam?

Candidates must hold primary ABMS certification in Neurology, Neurosurgery, Anesthesiology, Internal Medicine, or Emergency Medicine, and hold a valid unrestricted medical license at the time of examination. For the 2021-2026 exams, a temporary practice pathway (UCNS/CAST certification, a qualifying fellowship, or attested NCC clinical practice) was open to neurology/child neurology candidates. After the 2026 administration, most candidates need either 1 year of ACGME-accredited general critical care fellowship plus 1 year of ACGME-accredited neurocritical care fellowship, or 2 years of ACGME-accredited neurocritical care fellowship; neurosurgery candidates need 1 year of ACGME-accredited NCC fellowship, and internal medicine candidates need ABIM Critical Care Medicine certification plus 1 year of ACGME-accredited NCC fellowship. Application is submitted through the ABPN website (or the candidate's own board, for ABA/ABEM/ABIM/ABNS diplomates) during the designated application window.

What is the format of the exam?

The exam is delivered at Pearson VUE test centers in five 54-question sections (270 one-best-answer multiple-choice items total), with 320 minutes of scheduled testing time (5 min NDA/tutorial, 310 min for the questions, 5 min survey) plus up to 40 minutes of optional pooled breaks between sections. Questions frequently include clinical vignettes with neuroimaging (non-contrast CT for ICH/SAH/herniation, CTA for aneurysm or LVO, CT perfusion, DWI/FLAIR MRI), invasive monitoring waveforms (ICP, EVD), continuous EEG patterns (status epilepticus, burst suppression, malignant post-arrest), and decision algorithms for ICP escalation, brain death determination, and post-arrest neuroprognostication.

How much does the 2026 ABPN Neurocritical Care exam cost?

The 2026 Initial Subspecialty Certification Examination Fee is $1,900, plus a $500 late application fee if applicable. Cancellation and refund policies follow the ABPN schedule with decreasing refunds as the exam date approaches. ABPN states there is currently no limit on the number of times an applicant may apply to take the initial certification exam; each attempt requires full re-registration and fee payment. Enrollment in the ABPN Continuing Certification (MOC) program includes annual activities and associated fees.

What are the highest-yield topics?

Highest-yield topics include: Brain Trauma Foundation thresholds (ICP >22 mm Hg, CPP 60-70 mm Hg) and tiered ICP management (hyperosmolar therapy with 3% saline or mannitol, EVD CSF drainage, decompressive craniectomy per RESCUEicp); aneurysmal SAH management (aneurysm securement as early as feasible, preferably within 24 h [2023 AHA/ASA], nimodipine 60 mg q4h × 21 days, TCD vasospasm monitoring, induced hypertension for symptomatic DCI); ESETT-staged status epilepticus algorithm (lorazepam → fosphenytoin/levetiracetam/valproate → continuous midazolam/propofol/pentobarbital); AAN/AAP/CNS/SCCM 2023 brain death determination prerequisites and the apnea test (requires ALL of no respirations, pH <7.30, AND PaCO2 ≥60 mm Hg and ≥20 mm Hg above baseline); the 2025 AHA post-cardiac arrest target temperature of 32-37.5 °C for ≥36 h and post-cardiac arrest neuroprognostication ≥72 h (N20 SSEP, NSE, EEG, DWI); 20/30/40 rule for neuromuscular respiratory failure; the 2022 AHA/ASA ICH guideline (SBP 150-220 → target 140, maintain 130-150 [COR 2b]; <130 potentially harmful); and propofol infusion syndrome thresholds.

How should I study for the Neurocritical Care boards?

Plan 300-500 hours over 9-15 months during and after fellowship. Core resources include the Neurocritical Care Society Practice Update materials, Continuum Lifelong Learning in Neurology — Neurocritical Care issues, Brain Trauma Foundation 4th edition guidelines, the 2022 AHA/ASA spontaneous ICH guideline and 2026 AHA/ASA acute ischemic stroke guideline, the AAN/AAP/CNS/SCCM 2023 brain death consensus update, NCS status epilepticus guidelines, and the ABPN Neurocritical Care Content Specifications. Drill high-volume MCQs with timed sets, master trial acronyms (DAWN, DEFUSE-3, SELECT2, ATTENTION, ESETT, RESCUEicp, DECRA, TTM2, BOOST-3, INTERACT3, ATACH-2, ISAT, RAMPART, STASCIS), and complete 2-3 full-length (270-question) timed mock exams.

When is the 2026 exam administered?

The Neurocritical Care exam is offered by ABPN every other year, in even-numbered years. The 2026 exam is scheduled for October 5-9, 2026, with the next administration in 2028. Applications open months before the exam with a submission deadline prior to the testing window, after which candidates schedule specific Pearson VUE appointments.

How is the exam scored?

ABPN uses a criterion-referenced scaled scoring system with a passing standard set by subject-matter experts. A candidate's pass/fail result depends on performance relative to the fixed cut-score rather than on other test-takers. Score reports include subdomain performance to guide future learning. Score reports are typically provided within 10-12 weeks after the testing window closes, per ABPN/Pearson VUE.
