Neurology for the MCCQE Part I: Stroke, Seizures, Headache and Cord Emergencies

Weight and scope

Sixteen questions is about twenty-two minutes. The domain contains a small number of true emergencies (stroke, status epilepticus, meningitis, cord compression, subarachnoid hemorrhage), and these decide many marks. The remaining content is chronic disease, where the questions ask about diagnosis, drug choice, monitoring and counselling. Dementia and delirium also appear in geriatric and psychiatric stems, and head injury overlaps with trauma.

The MCC publishes no discipline weights. The 7% figure is our editorial estimate from the MCC Examination Objectives and clinical presentations, and the count is rounded because some items in each section are unscored. Questions from this domain are also spread across the four dimensions of care and the four physician activities.

What is tested

• Cerebrovascular disease. Ischemic stroke and TIA acute treatment and secondary prevention; intracerebral and subarachnoid hemorrhage.
• Seizures. Epilepsy classification, first seizure management, status epilepticus and driving advice.
• Headache. Migraine, cluster headache, giant cell arteritis and the signs of raised intracranial pressure.
• Infection. Meningitis and encephalitis, including the decision to treat before imaging or lumbar puncture.
• Chronic neurological disease. Parkinson disease and movement disorders, multiple sclerosis, motor neuron disease, myasthenia gravis and Guillain-Barre syndrome.
• Cognition. Dementia and delirium, and how to separate them from depression.
• Spine and nerves. Spinal cord compression, cauda equina syndrome, peripheral neuropathy and entrapment neuropathies.
• Structural and traumatic. Brain tumours, head injury, dizziness and vertigo, coma and brain death, and neurological examination with localization.

Canadian points to anchor your answers

• Time-critical stroke care. Learn the Canadian approach to the stroke patient: urgent imaging and the treatment decision within the time window. Take the time limits and drug criteria from the Canadian stroke guidance, because we do not state them here.
• Hypertension after stroke or TIA. Hypertension Canada favours an ACE inhibitor with a thiazide-like diuretic for secondary prevention.
• Dementia screening. The task force published guidance on cognitive impairment in 2024. Check the direction in the source.
• Brain death and consent. Capacity and substitute decision-making follow provincial law. The stem names the province when it matters.
• Driving. The duty to report an unfit driver is mandatory in some provinces and discretionary in others. Read the stem.
• Canadian CT Head Rule. The rule appears in the emergency domain. Use it as a named rule and state the inclusion criteria in your reasoning.

How the questions are framed

Neurology stems usually begin with a time course: sudden, over hours, over days, over months. The time course often decides the diagnosis. The examination findings localize the problem to the brain, the spinal cord, the nerve root, the peripheral nerve, the neuromuscular junction or the muscle. The question then asks for the most likely diagnosis, the next step or the treatment.

Management items favour the first safe action: protect the airway, check glucose, image the brain, treat reversible causes. Communication items include breaking the news of a progressive diagnosis, capacity in dementia and driving advice. Professional-behaviour items include substitute decision-making and end-of-life questions.

Three typical traps

1. Delaying treatment for an investigation in suspected bacterial meningitis. When the patient is unwell and delays are likely, the expected answer is to start empiric treatment promptly and arrange the diagnostic steps around it.
2. Missing the red-flag headache. Sudden severe onset, fever with neck stiffness, age over 50 with new headache and jaw claudication, or papilledema change the pathway. Read for the flag.
3. Confusing delirium with dementia or depression. Acute onset with fluctuating attention points to delirium and a search for a cause. Look for medications, infection and metabolic change.

How to revise it

1. Create a localization table with the signs for each level, from cortex to muscle.
2. Write a stroke pathway from recognition to secondary prevention, using the Canadian source for time limits.
3. List the neurological emergencies with the first action for each.
4. Practise delirium cases and the causes checklist.
5. Finish with timed blocks that include emergency and geriatric stems.

Pair this domain with the emergency and critical care, psychiatry and population health and ethics pages, where capacity, geriatrics and end-of-life decisions appear.

Subtopic checklist

Our blueprint lists these 15 subtopics for this domain. Tick each one only when you can state the presentation, the first investigation and the first management step without notes.

• Ischemic stroke and TIA: acute treatment and secondary prevention
• Intracerebral and subarachnoid hemorrhage
• Epilepsy and status epilepticus
• Headache: migraine, cluster, giant cell arteritis, raised intracranial pressure
• Meningitis and encephalitis
• Parkinson disease and movement disorders
• Multiple sclerosis
• Motor neuron disease, myasthenia gravis and Guillain-Barre syndrome
• Dementia and delirium
• Spinal cord compression and cauda equina syndrome
• Peripheral neuropathy and entrapment neuropathies
• Brain tumours and head injury
• Dizziness and vertigo
• Coma, altered level of consciousness and brain death
• Neurological examination and localization

How the four dimensions of care show up

Every question in this domain is classified under one dimension of care, so revise neurology in four ways, not one.

• Health promotion and illness prevention. Prevention: stroke risk reduction, blood pressure control, anticoagulation in atrial fibrillation and fall prevention.
• Acute care. Acute: stroke, status epilepticus, meningitis, subarachnoid hemorrhage and cord compression.
• Chronic care. Chronic: epilepsy care, Parkinson disease, multiple sclerosis, migraine prevention and dementia care.
• Psychosocial aspects. Psychosocial: caregiver strain, driving and work decisions, capacity, and living with a progressive disease.

When you review a wrong answer, note which dimension the question belonged to as well as the topic. A pattern, such as repeated errors on the prevention items, tells you more than a topic score.
