Vertigo and Dizziness Flashcards
angular accelaration by
semicircular canals
linear acceleration
utricle and saccule
categories of dizziness
true vertigo, syncope/presyncope, gait disturbance, lightheadedness/woozy
eyes drift towards which ear
fast beat towards
sick ear
normal ear
BPPV nystagmus
rotary and vertical towards the groun
Syncope/presycope signs
lightheaded, BL vision loss, diaphoresis, nausea
orthostasis
presyncopal on standing
nystagmus difference in peripheral versus central
peripheral-mixed horizontal and vertical - abnormal head impluse test Central -vertical nystagmus - pure horizontal - gaze-evoked
cold water to right ear
means left side active (nystagmus to left)
warm water in right ear
nystagmus to the right
Gait disturbance what you see with each:
- corticospinal
- extrapyramidal
- proprioceptive
- cerebllar
- lower motor neuron
- gait apraxia
- multi-sensory deficit syndrome
- corticospinal (UMN)
- extrapyramidal (parkinsons like)
- propropceptive (sensory ataxia dont know where legs are)
- cerebellar (wide based gait)
- LMN (muscle issue)
Time frame for vertigo
- BPPV
- Menieres disease
- TIA
- vestibular neuronitis/stroke/MS/migraine
BPPV- seconds
menieres- hours
TIA- minutes
MS/vestibular neuronitis- days
difference between vestibular neuronitis and labrinthitis
labrinthitis has hearing loss
BPPV
short onset of vertigo symptoms which are positional
meniere’s disease
tinnitus, hearing loss and vertigo (20min to 4 hours)
