- The UCNS Neurocritical Care Certification exam has exactly two content areas, each weighted at 50%.
- You must achieve a passing score in both content areas; strength in one cannot offset weakness in the other.
- The official outline has eight lettered subcategories under neurological disease states and twelve under general critical care.
- The initial exam has 200 multiple-choice questions with five hours allowed; the exam is offered biennially in odd-numbered years.
The Two Content Areas at a Glance
Neurocritical Care Certification (NCC), administered by the United Council for Neurologic Subspecialties (UCNS), is built on a deceptively simple blueprint: two content areas, split evenly. That symmetry is the single most important structural fact about the exam, and it should drive how you allocate every hour of preparation. If you are still orienting yourself to the credential itself, start with our explainer on what NCC certification is and then return here for the domain-level detail.
| Content Area | Weight | Lettered Subcategories in Official Outline |
|---|---|---|
| Neurological Disease States | 50% | 8 (A through H) |
| General Medical Critical Care | 50% | 12 (A through L) |
Notice the asymmetry hiding inside the symmetry. The two domains carry equal weight, yet the general critical care outline has half again as many subcategories. That means the general domain is broader and shallower in places, while the neurological domain is narrower but demands deep, integrated reasoning. Candidates who come from a neurology or neurosurgery background often find the second domain is where their preparation gaps live; candidates from medicine or anesthesiology critical care backgrounds frequently face the opposite problem.
For a broader view of how the whole preparation effort fits together, see our NCC study guide for passing on the first attempt.
The Pass-Both Rule and Why It Shapes Your Plan
The UCNS requires a passing score for both content areas to pass the certification examination. This is not a single blended percentage. A candidate who performs superbly on neurological disease states but falls short on general critical care does not pass, and the reverse is equally true.
An exact numeric passing threshold and a current cohort pass rate have not been verified from public sources, so be skeptical of any site quoting a precise cut score. We cover what is and is not known on our NCC passing score page and our NCC pass rate analysis. What you can rely on is the structural rule: clear both areas.
Domain 1: Neurological Disease States (50%)
The official detailed heading for this area is Neurological Disease States: Pathology, Pathophysiology and Therapy. It contains eight lettered subcategories. The outline lists topics but does not assign separate weights to subcategories or nested items, so the following walk-through is organized by the outline's own structure, not by invented percentages.
A. Cerebrovascular Diseases
Cerebrovascular Diseases
This is the densest subcategory in the domain, spanning ischemia, hemorrhage, malformations, and venous and arterial wall pathology.
- Infarction and ischemia: massive hemispheric infarction, basilar artery occlusion and stenosis, carotid occlusion and stenosis, crescendo TIAs, occlusive vasculopathies such as Moya-Moya and sickle cell disease, and spinal cord infarction.
- Intracranial hemorrhage: supratentorial, cerebellar, brainstem, and intraventricular locations.
- Subarachnoid hemorrhage: aneurysmal and other causes.
- Vascular malformations: arteriovenous malformations, AV fistulas, cavernous angiomas, and venous angiomas.
- Other entities: dural sinus thrombosis, carotid-cavernous fistulae, and cervical and cerebral arterial dissections.
B. Neurotrauma
Traumatic brain injury is broken into diffuse axonal injury, epidural and subdural hematoma, skull fracture, contusions and lacerations, penetrating craniocerebral injuries, and traumatic subarachnoid hemorrhage. Spinal cord injury covers traumatic injury (transection, contusion, concussion) as well as vertebral fracture and ligamentous instability.
C. Disorders, Diseases, Seizures and Epilepsy
Despite the slightly awkward heading, this is a broad grab-bag subcategory with six clusters:
- Seizures and epilepsy: status epilepticus in convulsive, non-convulsive, and myoclonic forms.
- Neuromuscular diseases: myasthenia gravis, Guillain-Barre syndrome, ALS, rhabdomyolysis and toxic myopathies, and critical illness myopathy and neuropathy.
- Infections: encephalitis and meningitis (viral, bacterial, parasitic) and brain and spinal epidural abscess.
- Toxic-metabolic disorders: neuroleptic malignant syndrome and malignant hyperthermia, serotonin syndrome, drug overdose and withdrawal (barbiturates, narcotics, alcohol, cocaine, acetaminophen), and temperature-related injuries.
- Inflammatory and demyelinating diseases: multiple sclerosis (including Marburg variant and transverse myelitis), neurosarcoidosis, ADEM, CNS vasculitis, chemical or sterile meningitis, central pontine myelinolysis, and others.
- Neuroendocrine disorders: pituitary apoplexy, diabetes insipidus, panhypopituitarism, and thyroid storm and coma.
D through H: Oncology, Encephalopathies, Syndromes, Perioperative Care, Pharmacotherapeutics
Remaining Neurological Subcategories
Each of these is shorter in the outline but equally testable.
- D. Neuro-oncology: brain tumors and metastases, spinal cord tumors and metastases, carcinomatous meningitis, and paraneoplastic syndromes.
- E. Encephalopathies: eclampsia including HELLP syndrome, hypertensive, hepatic, uremic, hypoxic-ischemic and anoxic encephalopathy, and MELAS.
- F. Clinical syndromes: coma; herniation syndromes with ICP monitoring; elevated intracranial pressure and intracranial hypotension; hydrocephalus; cord compression; death by neurologic criteria, end-of-life issues, and organ donation; vegetative state; dysautonomia; reversible posterior leukoencephalopathy; and psychiatric emergencies.
- G. Perioperative neurosurgical care
- H. Pharmacotherapeutics
Subcategories G and H are listed without nested detail, which makes them easy to underestimate. Because they cut across every disease state above, expect pharmacologic and perioperative reasoning to surface inside questions that are nominally about stroke, trauma, or seizures. Our NCC cheat sheet condenses many of these high-yield associations onto one page.
Domain 2: General Medical Critical Care (50%)
The percentage table calls this area General Medical Critical Care. The detailed outline heading, General Critical Care: Pathology, Pathophysiology and Therapy, drops the word "Medical." Either way, this half of the exam asks you to function as a competent intensivist for the non-neurological organ systems, because neurocritical patients rarely have only a neurological problem. It has twelve lettered subcategories.
A through C: Cardiovascular, Respiratory, Renal
Cardiovascular (A)
Covers shock and its complications (vasodilatory and cardiogenic), myocardial infarction and unstable coronary syndromes, neurogenic cardiac disturbances such as ECG changes and stunned myocardium, rhythm and conduction disturbances with antiarrhythmics and pacemakers, pulmonary embolism, cardiogenic versus noncardiogenic (including neurogenic) pulmonary edema, aortic and peripheral vascular emergencies, hypertensive emergencies and urgencies, and calculation of derived parameters including systemic and pulmonary vascular resistance, alveolar-arterial gradients, and oxygen transport and consumption.
Respiratory (B)
Includes hypoxemic respiratory failure (including ARDS), hypercapnic and neuromuscular respiratory failure, aspiration, bronchopulmonary infections, upper airway obstruction, COPD and status asthmaticus, neurogenic breathing patterns, and an extensive mechanical ventilation section: positive pressure ventilation, PEEP, CPAP, pressure support, pressure control, negative pressure ventilation, barotrauma, permissive hypercapnia, and weaning criteria and techniques. It also lists pleural diseases, pulmonary hemorrhage, chest X-ray interpretation, end tidal CO2 monitoring, sleep apnea, and control of breathing.
Renal (C)
Fluid, water, and electrolyte regulation; prerenal, renal, and postrenal failure; osmolality and electrolyte derangements; acid-base disorders; renal replacement therapy principles; oliguria and polyuria evaluation; drug dosing in renal failure; rhabdomyolysis management; and neurogenic disorders of sodium and water regulation, namely cerebral salt wasting and SIADH.
D through H: Systemic, Infectious, Hematologic, GI/GU, Immunology
- D. Systemic effects of critical illness: enteral and parenteral nutrition, endocrinology (thyroid storm, myxedema coma, sick euthyroid syndrome, adrenal crisis, ketotic and hyperosmolar coma, hypoglycemia, calcium and magnesium), SIRS, fever and cooling techniques, sedation management, and cognitive and neuropsychiatric outcomes.
- E. Infectious disease: antibacterial, antifungal, antituberculosis, antiviral, and antiparasitic agents; infection control and resistance; tetanus and botulism; hospital-acquired and opportunistic infections; AIDS; ICU fever evaluation; central fever; and interpretation of antibiotic concentrations and sensitivities.
- F. Acute hematologic disorders: thrombocytopenia, DIC, acute hemorrhage, iatrogenic coagulopathies, anticoagulation and fibrinolytic therapy, blood component therapy, hemostatic agents (vitamin K, aminocaproic acid, protamine, factor VIIa), thromboembolism prophylaxis, and prothrombotic states.
- G. Acute GI and GU disorders: GI bleeding, acute and fulminant hepatic failure, ileus and toxic megacolon, perforation, mesenteric ischemia, obstruction, pancreatitis, obstructive uropathy, and urinary tract bleeding.
- H. Immunology and transplantation: principles of transplantation including brain death, organ donation, procurement, and donor maintenance, plus neurotoxicity of immunosuppressants.
I through L: Trauma, Monitoring, Administration, Ethics
The Often-Neglected Final Four
Candidates who study only clinical medicine tend to skip these, yet they are part of the official scope.
- I. General trauma and burns: multisystem trauma approach, skeletal trauma including spine and pelvis, blunt and penetrating chest and abdominal trauma, burns and electrical injury.
- J. Monitoring: neuromonitoring, prognostic and severity scores, ECG monitoring, invasive and noninvasive hemodynamics, respiratory monitoring, metabolic monitoring (oxygen consumption, carbon dioxide production, respiratory quotient), and computer-based multimodality monitoring.
- K. Administrative and management principles: unit organization and staffing, multidisciplinary rounds, prehospital emergency systems, performance improvement, triage and resource allocation, and medical economics.
- L. Ethical and legal aspects: death and dying, forgoing life-sustaining treatment and DNR orders, patient rights, advance directives, terminal extubation and palliative care, rationing, emotional management of patients and families, and futility.
A Wording Quirk in the Official Outline
If you cross-reference the percentage table against the detailed outline, you will notice the second domain is named slightly differently in each place: "General Medical Critical Care" in the weighting table, and "General Critical Care" in the detailed heading. This is a source wording distinction, not a sign of two different content areas. Treat them as one domain. We mention it because candidates sometimes assume the discrepancy means a hidden third area or a revised outline. It does not. The currently linked official outline was reviewed with no verifiable revision or effective date, so avoid claims that the blueprint was freshly overhauled for the next cycle.
You may also see the outline's numbering contain a repeated item under cerebrovascular diseases, where two entries carry the same number. That is simply how the source is formatted.
Where the Two Domains Overlap
The clean 50/50 split on paper masks real overlap in practice. Several topics sit on the boundary, and recognizing them lets you study once and score twice.
- Brain death and organ donation: appears under neurological clinical syndromes (death by neurologic criteria) and again under immunology and transplantation (donor maintenance, procurement).
- Sodium disorders: diabetes insipidus belongs to the neuroendocrine cluster, while cerebral salt wasting and SIADH sit in the renal subcategory. They are tested as a differential family.
- Fever: central fever and dysautonomia appear in the neurological domain; fever evaluation, thermoregulation, and cooling appear in the general domain.
- Neurogenic cardiopulmonary effects: stunned myocardium, ECG changes, and neurogenic pulmonary edema live in the cardiovascular subcategory but are caused by neurological insults.
- Thyroid storm: listed under neuroendocrine disorders and again under systemic endocrinology.
- Neuromuscular respiratory failure: bridges Guillain-Barre and myasthenia gravis with ventilator management and weaning criteria.
Exam Format and Scheduling Facts
The initial certification examination contains 200 multiple-choice questions and permits five hours. Since January 1, 2025, it has been available at testing centers or through virtual live proctoring. UCNS describes the exam as biennial, offered in odd-numbered years. The issuer page currently lists the next examination week as November 15-19, 2027, with applications opening February 1, 2027. Always verify future scheduling directly with the issuer, since dates can shift. Our NCC exam dates guide tracks the windows and deadlines in more detail.
Because the blueprint is evenly split, a rough mental model is that around half the questions come from each content area, though the issuer does not publish a per-subcategory item count. Our difficulty guide discusses why the breadth of the general critical care outline, rather than any single topic, is what most often makes the exam feel hard.
For eligibility questions, see NCC requirements and prerequisites, and for fees, the NCC certification cost breakdown. Those pages cover the application mechanics that this domain-focused article deliberately leaves aside.
Sequencing Your Preparation by Domain
Generic scheduling advice is less useful than a domain-aware sequence. The logic below is tied to the structure of the outline: start with whichever half is your weaker, then interleave overlap topics, and reserve time for the administrative and ethics subcategories that candidates habitually postpone.
Diagnose your weaker domain
- Take a diagnostic practice set from our practice test site and score the two content areas separately.
- Identify which lettered subcategories drive your misses.
Attack the weaker domain first
- If general critical care is weaker, begin with respiratory, cardiovascular, and renal subcategories, which carry heavy calculation and physiology content.
- If neurological disease states is weaker, begin with cerebrovascular disease and clinical syndromes such as ICP and herniation.
Cover the second domain and the bridge topics
- Work through the remaining domain in outline order.
- Build your overlap notes: sodium disorders, fever, brain death, neurogenic cardiopulmonary effects.
Sweep the neglected subcategories
- Review monitoring, trauma and burns, administration, and ethics and legal topics.
- Return to mixed-domain practice and recheck both domain scores.
Practice material from any provider, including ours, is original supplemental education. It is not actual examination content, is not endorsed by the issuer, and cannot guarantee a pass. Use it to find gaps, then return to the official outline to confirm scope.
What This Credential Is Not
The acronym "NCC" is shared by several unrelated credentials, so it is worth being precise. The exam discussed here is the UCNS Neurocritical Care Certification. It is not the separate UCNS Neonatal Neurocritical Care credential, and it is not an ABPN certification. UCNS explicitly continues its own NCC certification examination, including its practice track, separately from ABPN certification, and UCNS certification does not automatically transfer to ABPN, which requires its own examination. Do not apply another body's outline, weights, or scoring to this exam.
Once certified, UCNS annual continuous certification (C-cert) replaces a high-stakes recertification examination when annual requirements are met. That is distinct from the initial exam described in this article. If you are weighing the career side, our pages on whether the certification is worth it, earnings, and NCC jobs take that up directly, and the topic lists here describe examination scope only, not patient-specific treatment instructions.
Frequently Asked Questions
Two. Neurological Disease States and General Medical Critical Care each account for 50% of the exam, and you must pass both content areas to pass the certification examination.
No. The official outline gives only the 50/50 split between the two content areas. Subcategories and nested topics have no separately published weights, so any finer breakdown you see elsewhere is an editorial estimate rather than an official figure.
No. Passing requires a passing score in each content area. An exact numeric passing threshold has not been verified from public sources, so be cautious of anyone advertising a single aggregate cut score.
The initial certification examination has 200 multiple-choice questions and allows five hours. It is available at testing centers or through virtual live proctoring, and UCNS describes it as biennial in odd-numbered years. Confirm current dates with the issuer.
Start with whichever you score lower on in a diagnostic, since you must clear both. Then use bridge topics such as sodium disorders, fever, brain death, and neurogenic cardiopulmonary effects to reinforce both areas at once. For a fuller plan, see the NCC study guide.
