ABPN Neurocritical Care study guide
ABPN Neurocritical Care · Work through your exam, one topic at a time.
The ABPN Neurocritical Care examination is a subspecialty certification exam for physicians who have completed neurology training and advanced fellowship training in neurocritical care, and who manage critically ill patients with primary neurologic disease as well as neurologic complications of systemic illness. The exam samples broadly across the field: neurophysiology and intracranial dynamics, ischemic and hemorrhagic stroke including neurointerventional care, traumatic brain and spinal cord injury, status epilepticus and continuous EEG, neuromuscular and neuroinfectious emergencies, postoperative neurosurgical care, multisystem organ support, neuroimaging and neuromonitoring including brain death determination, ethics and prognostication, and neuropharmacology and toxicology. The ABPN Neurocritical Care study guide has 10 sections and about 2,458 words.
01Neurocritical Care Fundamentals and Neurophysiology
Monro-Kellie doctrine governs everything intracranial: brain, blood, and CSF share a fixed volume, so any added volume (edema, hematoma, hydrocephalus) must displace another or raise ICP. Understand the pressure-volume curve - compliance falls steeply as ICP rises, so small volume changes near the steep portion cause large ICP swings.
301 words, about 2 min02Cerebrovascular Disease and Neurointerventional Critical Care
Master the distinction between ischemic and hemorrhagic stroke management. For ischemic stroke, the time-critical question is reperfusion: IV thrombolysis window (≤4.5 h with select exceptions) and mechanical thrombectomy for large-vessel occlusion (extended windows with perfusion imaging).
265 words, about 1 min03Traumatic Brain Injury and Spinal Cord Injury
Separate primary from secondary injury. Primary injury is immediate and untreatable; secondary injury (hypoxia, hypotension, hyperthermia, hyperglycemia, seizures) is the target of ICU care.
268 words, about 1 min04Status Epilepticus, Seizures, and EEG Monitoring
Status epilepticus is continuous seizure activity ≥5 min or recurrent seizures without recovery. Treat time-critically: benzodiazepines first (lorazepam, midazolam), then a second-line antiseizure medication (levetiracetam, fosphenytoin, valproate), then anesthetic agents (midazolam, propofol, pentobarbital) for refractory disease.
227 words, about 1 min05Neuromuscular and Neuroinfectious Disease in the ICU
Recognize the "can't breathe" neuromuscular disorders: Guillain-Barré syndrome (GBS), myasthenia gravis (MG) crisis, and critical illness weakness. In GBS, monitor vital capacity and negative inspiratory force - respiratory failure can be precipitous; autonomic instability is common.
256 words, about 1 min06Neurosurgical and Postoperative Critical Care
After craniotomy or spine surgery, the ICU focuses on detecting complications: hemorrhage, edema, seizures, hydrocephalus, and CSF leak. Neurologic checks are the most sensitive monitor - a declining exam often precedes imaging changes.
225 words, about 1 min07Multisystem Critical Care and Organ Support
Neurocritical patients often have multiorgan failure. Master the interaction between brain injury and systemic physiology: hypotension and hypoxia worsen brain injury, and fever, hyperglycemia, and anemia are modifiable harms.
221 words, about 1 min08Neuroimaging, Neuromonitoring, and Brain Death
Know when to use CT (hemorrhage, herniation, hydrocephalus), MRI (ischemia, infection, demyelination), and vascular imaging (CTA/MRA/DSA). Understand the significance of midline shift, herniation signs (effaced cisterns, uncal herniation), and the limitations of early CT in ischemia.
251 words, about 1 min09Ethics, Prognostication, and End-of-Life Care
Prognostication after severe brain injury is uncertain and should be multimodal and delayed - avoid early self-fulfilling prophecies from premature withdrawal. Use clinical exam, imaging, EEG, and biomarkers, and communicate uncertainty honestly.
229 words, about 1 min10Pharmacology and Toxicology in Neurocritical Care
Know the neurocritical drugs and their pitfalls: osmotic agents (mannitol vs hypertonic saline), antiseizure medications, sedatives (propofol, midazolam, dexmedetomidine), vasopressors, and anticoagulants/reversal agents. Understand pharmacokinetics in critically ill patients (altered volume of distribution, organ dysfunction) and drug interactions.
