Dizziness History Taking | OSCE Tips
Dizziness history taking Learn a structured dizziness history for OSCEs, including key questions, red flags, differentials and examination points for PA students..
1. 🧼 Opening the Consultation
- Wash or sanitise hands
- Introduce yourself: "Hi, my name is (Name), one of the physician associates"
- Confirm the patient's full name and date of birth
- Gain consent: "Would it be okay if I asked you some questions about the dizziness you've been experiencing?"
- Check that the patient feels safe sitting where they are, particularly if they are currently very dizzy or unsteady
2. ❓ Presenting Complaint
-
Start with an open question:
- "Can you tell me what's been happening?"
- "What do you mean when you say you feel dizzy?"
-
Clarify the sensation rather than assuming "dizziness" means vertigo:
- "Does it feel as though you or the room is spinning?"
- "Do you feel as though you might faint or pass out?"
- "Do you feel unsteady when walking?"
- "Or is it more of a vague light headed or floating feeling?"
-
If the patient says… You should consider… "The room spins" Vertigo - consider vestibular causes such as BPPV, vestibular neuritis, labyrinthitis, Ménière's disease or vestibular migraine "I feel like I'm going to faint" Presyncope - consider postural hypotension, vasovagal episodes, arrhythmia, dehydration or anaemia "I'm unsteady when I walk" Disequilibrium - consider neurological, vestibular, sensory or medication-related causes "It happens when I roll over in bed" BPPV "It happens when I stand up" Postural hypotension "I get dizzy with palpitations" Possible cardiac arrhythmia "It suddenly started and I can't walk properly" Acute vestibular syndrome - central causes including posterior circulation stroke must be considered
3. 🩺 History of Presenting Complaint
-
Onset: "When did the dizziness first start?"
Sudden onset raises concern for BPPV, acute vestibular disorders, cardiovascular causes and posterior circulation stroke. Gradual or recurrent symptoms may suggest medication effects, migraine or chronic vestibular disease.
-
What were you doing?: "What were you doing when it started?"
Turning in bed suggests BPPV. Standing suggests postural hypotension. Exertional symptoms raise concern for a cardiovascular cause.
-
Duration: "How long does each episode last?"
Duration is often more useful than a severity score when distinguishing causes of dizziness.
-
Continuous or episodic: "Are you dizzy all the time, or does it come in attacks?"
Brief triggered episodes favour BPPV. Persistent acute vertigo lasting hours to days suggests an acute vestibular syndrome and requires careful assessment for central causes.
-
Triggers: "Does anything bring the dizziness on?"
- Turning the head?
- Rolling over in bed?
- Looking upwards?
- Standing from sitting or lying?
- Exercise?
True positional triggering from an otherwise settled baseline supports BPPV. Movement simply making continuous vertigo worse does not automatically mean BPPV.
- Progression: "Is it getting better, worse or staying the same?"
-
Previous episodes: "Has anything like this happened before?"
Recurrent stereotyped attacks may suggest BPPV, vestibular migraine, Ménière's disease or an intermittent cardiovascular cause.
-
Functional severity:
- "Are you able to walk normally?"
- "Have you fallen or needed someone to support you?"
- "Are you able to carry out your normal activities?"
New severe gait unsteadiness is particularly important in sudden-onset dizziness and may suggest a central neurological cause.
| Pattern | You should consider… |
|---|---|
| Brief rotational vertigo triggered by rolling over, looking up or turning the head | BPPV |
| Acute persistent vertigo + nausea/vomiting + gait unsteadiness, without hearing loss | Vestibular neuritis, but posterior circulation stroke must be excluded where appropriate |
| Persistent vertigo + hearing loss/tinnitus following an infective illness | Labyrinthitis |
| Recurrent vertigo + fluctuating hearing loss + tinnitus/aural fullness | Ménière's disease |
| Episodes lasting minutes to hours with migraine history, headache, photophobia or phonophobia | Vestibular migraine |
| Light-headedness shortly after standing | Postural hypotension |
| Light-headedness + palpitations, chest symptoms or syncope | Cardiac arrhythmia or other cardiovascular cause |
| Sudden persistent vertigo + neurological deficit or marked gait disturbance | Posterior circulation stroke until adequately assessed |

10. 🧾 Summarise & Explain Next Steps
"So, you've been experiencing (spinning/light-headedness/unsteadiness) for (duration). It tends to occur when (trigger) and lasts around (duration). You have also noticed (associated symptoms), but you haven't had (important negatives/red flags)".
"I'd like to examine you and perform some targeted checks to help determine whether this is coming from the inner ear, blood pressure, heart or nervous system".
- Observations including pulse and blood pressure
- Capillary glucose where clinically indicated
- Lying and standing blood pressure if postural symptoms are suspected
- Ear examination and hearing assessment where indicated
- Neurological examination including gait, coordination and assessment of nystagmus
- Cardiovascular examination
- Hallpike manoeuvre if transient positional rotational vertigo suggests BPPV and the clinician is trained to perform it
- HINTS assessment only in appropriate acute vestibular syndrome and when performed by someone trained and experienced in its use
- 12-lead ECG if presyncope, syncope, palpitations or a cardiovascular cause is suspected
- Targeted blood tests where clinically indicated rather than routine screening
Sudden onset acute vestibular syndrome, focal neurological abnormalities, new severe gait disturbance or other features concerning for posterior circulation stroke require urgent assessment through the appropriate acute stroke pathway.
🎓 Present Back to Examiner (PA Format)
"This is a (age)-year-old (man/woman) presenting with a (duration) history of (episodic/continuous) dizziness described as (rotational vertigo/light headedness/unsteadiness). Episodes last approximately (duration) and are triggered by (trigger). Associated features include (relevant positives), with no (key neurological/cardiac red flags). Relevant background includes (PMH/medications). My leading differential is (diagnosis), with differentials including (diagnosis 2) and (diagnosis 3). I would perform observations, lying and standing blood pressure where indicated, a focused cardiovascular, neurological and ear examination and select further investigations according to the suspected cause".
