Vertigo Flashcards
A 68 year old woman presents feeling dizzy and vomiting. She reports intermittent episodes of “the world spinning” over the last 4 days made worse by movement. She is currently vomiting profusely and unable to stand or walk. How would you assess and manage her?
Impression
This woman’’s presentation is vertiginous in nature, there are a number of causes of vertigo to be considered;
DDx
- Central: posterior/brainstem stroke, SOL, vestibular migraine, demyelinating condition
- Peripheral: Vestibular neuritis, BPPV, Menieres disease, seizure
- Syncope/Pre-syncope causes (alternative diagnosis)
Vertigo - History
History
- PC: timing, onset of symptoms. Clarify if world spinning, or just sensation of ‘dizziness’ vs other. Timing - acute + persistent is more likely central vs peripheral.
- assoc: raised ICP (early morning vomiting, etc)
- Menieres: tinnitus + hearing loss + vertigo
- vestibular neuritis: preceding viral illness
- migraine: aura, history of migraines, etc
- Stroke: other neurological signs (FAST), weakness, CVD risk factors
- PMHx, medications (recent ototoxic ABx’s)
- Psychosocial - home environment, falls risk
- SNAP
Vertigo - Examination
Examination
- General appearance + vitals
- Neurological exam: focal neurological deficits, cerebellar testing (DANISH R, gait)
- HINTS exam (if suspecting central cause)
o Head impulse (if absent then likely central)
o Nystagmus: central = vertical or bidirectional
o Test of skew: vertical corrections = central
- Dix-Hallpike: if thinking BPPV
o can also perform Epley’s manoeuvre for therapeutically
Vertigo - Investigations
Investigations Vertigo is mostly a clinical diagnosis. - Bedside: audiometry - Bloods: EUC, CRP/ESR - Imaging: MRI Brain if suspicious of central cause
Vertigo - Management
Management Supportive - Fluids/electrlytes - analgesia - antiemetics - antivertigo meds: antihistamines + benzodiazepines - patient education (especially if BPPV)
Definitive - depends on underlying cause
- BPPV: referral to physio for therapeutic maneouvres and further patient education - modified employ manoeuvre for posterior canal crystals. Repeat treatment 3x daily until symptom free for 24 hours
- Meniere’s disease:
o salt restriction, limit caffeine intake
o pharmacological: Hydrochlorothiazide +/- amiloride
o antiemetics in acute attack
- Vestibular neuritis: counselling that symptoms will improve over time
