ABPN Brain Injury Medicine study guide
ABPN Brain Injury Medicine · Work through your exam, one topic at a time.
Brain Injury Medicine is an ABPN subspecialty certification for physicians who already hold a primary neurology or physical medicine and rehabilitation certification and who want formal recognition of expertise in acquired brain injury. It is aimed at clinicians who evaluate and manage patients across the continuum - from acute and critical care through inpatient rehabilitation, community reintegration, and long-term outpatient follow-up. The ABPN Brain Injury Medicine study guide has 8 sections and about 1,976 words.
01Basic Neuroscience and Neuropathology of Brain Injury
Know the primary versus secondary injury distinction: primary injury is the mechanical event (contusion, diffuse axonal injury, hematoma, penetrating injury); secondary injury is the downstream biochemical cascade (excitotoxicity, calcium influx, mitochondrial failure, oxidative stress, neuroinflammation, edema). Candidates must understand diffuse axonal injury (DAI) - shearing at gray-white junctions from angular acceleration, with axonal swelling and impaired axonal transport; classic locations are the corpus callosum, dorsolateral brainstem, and subcortical white matter.
277 words, about 1 min02Epidemiology, Prevention, and Mechanisms of Brain Injury
Understand population-level patterns of traumatic brain injury (TBI) : incidence peaks in young adults (motor vehicle crashes, sports) and older adults (falls), with males overrepresented except in older fall cohorts. Know that falls are the leading cause of TBI-related hospitalization in older adults; motor vehicle crashes and firearm injury dominate severe TBI and mortality.
284 words, about 1 min03Clinical Assessment and Diagnosis of Brain Injury
Master the Glasgow Coma Scale (GCS) - eye, verbal, motor - and its severity bands (mild 13–15, moderate 9–12, severe ≤8). Know that the motor component is the strongest prognostic subscale.
257 words, about 1 min04Acute and Critical Care Management of Brain Injury
Understand the Monro-Kellie doctrine and intracranial pressure (ICP) management: head-of-bed elevation, sedation, osmotic therapy (hypertonic saline, mannitol), CSF diversion, and decompressive surgery for refractory elevation. Know cerebral perfusion pressure (CPP) = MAP − ICP and the rationale for blood pressure targets.
241 words, about 1 min05Neurorehabilitation and Recovery
Understand neuroplasticity - activity-dependent reorganization, critical periods, and the principle that task-specific, intensive, repetitive practice drives recovery. Know the multidisciplinary team (physiatry, PT, OT, speech, neuropsychology, nursing, social work).
225 words, about 1 min06Neuropsychiatric, Cognitive, and Behavioral Sequelae
Know the cognitive domains affected after TBI: attention/processing speed, executive function, memory, and social cognition, with frontal lobe vulnerability. Understand post-traumatic amnesia (PTA) as a marker of severity and its assessment (e.g., orientation questions).
226 words, about 1 min07Medical Complications and Comorbidity Management
Know the common complications after brain injury: seizures (early vs late post-traumatic epilepsy), hydrocephalus (communicating after subarachnoid blood), heterotopic ossification , spasticity/contractures , venous thromboembolism (prophylaxis is essential), dysphagia and aspiration , pressure injuries , neuroendocrine dysfunction (hypopituitarism after TBI), and autonomic dysfunction/paroxysmal sympathetic hyperactivity (tachycardia, hypertension, diaphoresis, posturing). Understand sleep-wake disorders and their effect on cognition and mood.
226 words, about 1 min08Ethics, Legal, and Systems of Care
Understand informed consent and decision-making capacity - capacity is task-specific, not global; assess understanding, appreciation, reasoning, and choice. Know surrogate decision-making hierarchies and advance directives.
