How to Take a Neurological History — OSCE Guide

Why Neurology History Taking Is High-Stakes

Neurology stations are feared by medical students because the clinical presentations are diverse and the differentials complex. However, the history framework is actually highly structured — and once you've mastered it, neurology becomes one of your most reliable OSCE stations.

The key is localisation: which part of the nervous system is affected? Your history questions should be directed at answering this anatomical question.

The Core Neurological Framework

For any neurological presentation, work through:

1. 1SOCRATES for the primary symptom
2. 2Neurological screen (functional impact + associated neurological symptoms)
3. 3Red flag screen
4. 4Systematic review (PMH, DHx, FHx, SHx)

Headache — The High-Risk Station

Headache is the most common neurology OSCE station and the highest-stakes because of the red flags.

SOCRATES for Headache

Headache Red Flags (SNOOP)

Differentiating Headache Types

Weakness — Localising the Lesion

When a patient presents with weakness, your history should answer: Upper or lower motor neurone? Which territory?

SOCRATES Plus Specific Questions

• "Which parts of your body feel weak?"
• "Did it come on suddenly or gradually?" (sudden = vascular; gradual = demyelinating/tumour)
• "Is it affecting one side or both?"
• "Upper body, lower body, or one limb?"
• "Any problems walking or climbing stairs?"

Associated Symptoms — Ask Systematically

• Sensory symptoms: "Any numbness, tingling, or pins and needles alongside the weakness?"
• Speech: "Any difficulty speaking or finding words?"
• Vision: "Any double vision, blurred vision, or visual loss?"
• Bladder/bowel: "Any problems passing urine or opening your bowels?" (spinal cord involvement)
• Dysphagia: "Any difficulty swallowing?"
• Diurnal variation: "Is the weakness worse at the end of the day?" (myasthenia gravis)

Seizures — Essential Questions

A seizure history requires four phases:

Pre-Ictal

• "Did you have any warning before it happened — a feeling, smell, visual change, or déjà vu?" (aura = focal onset)
• "Were you fully conscious in the minutes before?"
• "Had you been drinking alcohol or taken any new medications?"

Ictal (from witness account)

• "Did anyone see it happen? What did they describe?"
• "Did your whole body shake, or just one part?"
• "Did you fall? Did your eyes deviate?"
• "Were you conscious during it or did you lose awareness?"
• "How long did it last?"

Post-Ictal

• "How did you feel afterwards? Any confusion, headache, or weakness in one limb?" (Todd's paresis = focal onset)
• "Any tongue biting or urinary incontinence during?"
• "How long before you felt completely back to normal?"

Between Episodes

• "Have you had any previous episodes like this?"
• "Any history of childhood febrile convulsions?"
• "Any recent head injury or illness?"
• "Any family history of epilepsy?"
• Drug history: "Are you on any medications? Do you use recreational drugs or alcohol?"

Dizziness — Vertigo vs Presyncope

Dizziness is one of the most challenging histories because patients use the same word to mean very different things. Clarify first:

"When you say dizzy, can you describe what you mean? Is it a spinning sensation, or more like you might faint or black out?"

For vertigo:

• "Does it last seconds, minutes, or hours?" (BPPV = seconds; Ménière's = hours; vestibular neuritis = days)
• "Is it brought on by head movement?" (BPPV = yes)
• "Any hearing loss or tinnitus?" (Ménière's disease)
• "Any headache or neurological symptoms?" (posterior fossa stroke)

Systematic Review for Neurology

Always close with:

• Past neurological history (previous strokes, MS, epilepsy, migraines)
• Drug history — especially anticoagulants, antiepileptics, immunosuppressants
• Family history — MS, migraines, hereditary neuropathies, Huntington's
• Social history — smoking (stroke risk), alcohol (Wernicke's, peripheral neuropathy), occupation
