Differential Diagnosis Flashcards
room spins when turning in bed
BPPV
oscillopsia, constant imbalance
Bilateral vestibular hypofunction
turning head or turning around in standing
Unilateral vestibular hypofunction
feeling “off” with negative vestibular signs
Cervicogenic dizziness, psychologic
dizzy/lightheaded standing up first thing in morning
Orthostatic hypotension
visual motion sensitivity
Concussion, TBI, central dysfunction
Disequilibrium, spontaneous nystagmus, nausea, hearing unaffected, vertigo present when still, no UMN signs
Vestibular neuritis
Tinnitus, hearing loss, severe acute vertigo duration >30min, nausea/vomiting, sensation of fullness in ear
Meniere’s disease
Vertigo, possible history of head trauma, exacerbated by changes in air pressure (eg. Flying at altitude, ascending elevator), sensitive hearing/hearing loss, sense of ear fullness, tinnitus, no UMN signs
Perilymph fistula
Central vestibular disorder
mild vertigo with nausea and vomiting lasting >3 days, sensorimotor loss, diplopia, dysarthria (eg. Vertebrobasilar ischemia, brainstem tumor, MS, arnold-chiari malformation, etc)
Vertigo provoked with head movement, lasts few seconds up to a minute, general imbalance with walking and standing, nystagmus has short latency and fatigues with repetition
BPPV- repositioning maneuver, vestibular therapy for persistent imbalance, surgery for refractory cases (rare)
Vertigo provoked with head movement, lasts few seconds up to a minute, general imbalance with walking and standing, nystagmus has short latency and fatigues with repetition
BPPV- repositioning maneuver, vestibular therapy for persistent imbalance, surgery for refractory cases (rare)
Acute onset, Persistent constant rotational vertigo, postural imbalance, nystagmus, nausea, no hearing loss- lasts 24-72hours
- horizontal nystagmus (away from affected ear), significant postural instability
Vestibular neuritis
Acute unilateral vestibulopathy
- vestibular suppressants, corticosteroids
chronic varying degrees of dizziness or imbalance with head movement
- unilateral head thrust test may be positive
- reduce caloric response unilateral
- audiogram negative for hearing loss
Vestibular neuritis - chronic
- vestibular therapy to improve gaze stability, postural control, decrease residual feelings of dizziness
Acute onset, Persistent constant rotational vertigo, postural imbalance, nystagmus, nausea, hearing loss, tinnitus- lasts 24-72hours
- horizontal nystagmus (away from affected ear), significant postural instability
- associated with otitis media (bacterial or viral)
- audiogram positive for sensorineural hearing loss
Labyrinthitis - acute
- treat underlying cause (bacteria, viral)
- vestibular suppressants, steroids, antiviral medical
