exam 2 -vetsibular issue Flashcards
what is a vestibular issue
peri, central, or a combine vetsibular issue
is there a certain population vestibular issue are seen in
no seen in all population
what causes vestibualr issue
brain - cere, vest nuclei, BS
SSC
disorder of the otolith
peri vestibular issue sym presentations
o Dizziness with positional chnages
o Spinning
o Poor balance
o Vomiting
o Nausea
o Headache (seen more commonly in central issues)
o Ear issues
There may be hearing loss
Tinnitus
o Head movement during gait
what is oscillopsia
a vision problem in which still objects seem to jump, jiggle, or vibrate due to a misalignment of the eyes or systems controlling balance
is all dizziness vestibular
no I can be caused
medication
DM
POTS
thryroid conditions
renal failure
TIA
migraines
is upbeating nys central or peri
it can be either
is down beating nys central or peri
central - go see a neurologist
what are test of the cere
didiadokikinesia - rapid alternaing movement
alternative feet tapping
finger nose
what is included in the eye assesment
pupil size
pupil sym
facial nerve sym
what are signs that you should refer back to a physician
UMN signs
swallowing issues
change in sensation that is not explained by premorbid condition
having the worst headache of their life
LOC
eye change that would sign to refer back to a doctor
change in pupil size or ptosis that is not explained by a prior medical condition
falls and refferal to doctor
repeated unexplained falls
balance issue that should be referred to a docctor
sensation of being pushed off balance - may be a BS issue
ear issue that should be referred
fluctuating hearing loss
unilateral hearing loss
eye issue to referred
VF loss
memory and referred
memory loss
how long until you referrer back to the doctor
the pt status has not improved and you have seen the pt for 2-3 months of 3-5 visits
is is better to see vestibular pt is quick time period
no it is better to space out these patients
do we normally see straight or torsion nys with peri issue
torsional and vertical mixxed
do we normally see straight or torsion nys with central issue
straight/vertical
is vertigo common with central issue
uncommon
is vertigo common with peri issue
more common
do we see issue with saccades and smooth pursuits with central or peri issue more
central
is a report of LOC every a vestibular issue
no
what is positional dizziness assocciated with vertigo normallu caused by
free floating otoconia - it is a mechanical issue
how to test for hearing loss
rub your finger near the pt ears
is there a test for tinnitus
no
what should you test if you thing someone has a vest issue
o Hearing loss
o Tinnitus
o Gait analysis
o Balance test
o Positional testing
o Dizziness handicap inventory
what does DGI stand for
dynamic gait assessment
dizziness handicap index number
40 - BPPV
50 or higher - long term issues
when do we get imagine for the pt
risk factors for stroke
new onset of headaches with vertigo
neuro signs
vertigo that does resolve for 48 hours
do people always report that they have fallen
no this is why we need to ask specific questions
what is the clinically important change in gait speed for those with UVL
.2 –> .34
this lead to a large difference in self previeced balance and dizziness
tullio phenomanon
eye movement hat are inducced by loud noises
associated with an inner ear issue
hennebert sign
eye movements due to pressure in the external audiotory canal
valsalva manuever
bearing down, glottic pressure, cough, sneeze can elicit vestibular signs
who are surgical cadiates for Superior canal dehiscence
Debilitating Auditory and vestibular symptoms
physical finding - tuillo, hennebert
audiometric findings - low conductive hearing loss, intact stapes reflex
CT finding > canal dehisence
what does vestibular loss look like in children
increase poor balance
1/2 have vestibular abnormalities with vest testing
disequillibrum without vertigo possible causes
parkisons
neuropathy
senile gait
cere disorders
dementia - multi infract
normal pressure hyrocephalus
cenrtal issues and eye changes
pupil changes
ptosis
throat and central changes
diffuculty swallowing
causes of recurrent dizziness
mirgrain
VBI
panic disorder
causes of non-recurrent dizziness
concussion
BS stroke
cerebellar hemorrhage
MS
chiair malformation
multi-sensory disequilibrium
what is a Chiari malformations
structural defects where the lower part of your brain presses on and through an opening in the base of the skull and cerebellum into the spinal cana
physchatric dizziness
panic disorders
agoraphoria
hyperventilation syndrome
agoraphoria
A person with agoraphobia is afraid to leave environments they know or consider to be safe
what is PPPD
this is a a functional movement disorder
these individuals have a vest issue that they have a hard time recovering from
what is the cause of the presentation of PPPD
difference in their grey matter
so when there is a vestibular issue they are maladpative
recurrent attacks of vertigo - neuro signs
MS or VBI
recurrent attacks of vertigo - hearing loss
meniere’s
autoimmune disease
syphillis
recurrent attacks of vertigo - normal audiogram
meniere’s
mirgraines
VBI
what is vestibular mirgaine often confused with
sinus headache
benign paroxysmal vertigo of a child - vertigo
5 episode of serve vertigowith no warning
benign paroxysmal vertigo of a child - recovery
resolves spontaneously within min to hours
benign paroxysmal vertigo of a child - vets testing
when no symptomatic vest testing is normal
benign paroxysmal vertigo of a child - migrianes
consider as a precusor of migraines in adulthood
vest migraine and BPPV - presentation
vets migraine may demostrate positional vertigo
vest migraine and nys
persistant positional nys
is dizzines ever normal
no it does not matter the age of the pt
if you see gait ataxia is this most likely a central or a peri issue
central dysfunctionn
aminoglycosides - vertigo
cause vertigo and disequillibrum
what does pure vertical eye nys normally tell us
usually indicates cere atrophy, MS, cere tumor, Chiari malformation
Central spontaneous nys indicates
cere ectopia (abnormal positioning), degeneration, or ischemia (inadequate blood supply)
Down beating nys indicates
Chiari malformation, bilat BS lesion, bilat floccular lesion, vestibulocerebellum lesion
what could be the cause of post traumtic dizziness
perilymphatic dizziness
temporal bone fracture
post conccussion syndrome
labyrinthine concussion
BS hemorrhage
what is Valsalva
a forceful attempt at expiration when the airway is closed at some point
what is - Barotrauma
physical tissue damage caused by a pressure difference between an unvented space inside the body and surrounding gas or fluid
