- 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

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
