WEEK 2: Dizziness and Vertigo [Doc Salonga] NOT INCLUDED YET Flashcards
A sensation of lightheadedness, faintness, or unsteadiness; does not involve a rotational component.
Dizziness
The perception of movement or whirling, either of the self or surrounding objects.
Vertigo
Unsteadiness, imbalance, or loss of equilibrium, often accompanied by disorientation
Disequilibrium
A sensation of not knowing where one’s body is in relation to the vertical or horizontal planes
Spatial Disorientation
Lesion in the posterior fossa, anong test ang gagawin? CT or MRI?
MRI kasi nahahaharangan siya doon pag posterior fossa.
T or F? Dizziness does not involve a rotational
component.
T
have patient lie back on
examining table so that head hangs over edge at 30° below
horizontal. Do not move patient into this position too quickly.
Then have patient look straight ahead and watch for 30
seconds. If nystagmus and vertigo develop, note directions of
fast and slow phases and ask patient to describe sensations
Nylen-Barany Maneuver
in nylen barani, If vertigo
lasts longer than 60 seconds in this position, it is
called
persistent positional vertigo. if not, then, transient positional vertigo
if there is a positive sign in head thrust test, with a saccade back to the target, what does it indicate?
ipsilateral vestibular lesion
in head shaking test, where is the nystagmus if there is a bilateral vestibular loss?
NONE. no nystagmus
Unilateral vestibular neuritis or acoustic neuroma, where is the location of the nystagmus?
basta always going towards the better ear.
First phase nystagmus- where is the location of the nystagmus?
the nystagmus will be away from
the lesion.
If it is a problem with the connection of the vestibular system
with the cerebellum, then the nystagmus will be
bidirectional.
Down beat nystagmus- not associated with vestibular lesions. T or F?
T
if it persists and is not episodic then that is not considered as BPPV T or F?
T
rapid phase nystagmus what direction? slow pahse? environment? romberg’s sign?
rapid is away
slow phase is toward
environment is spinning away from lesion
Romberg’s sign toward the lesion
give some of the red flags in patients with vertigo
double vision headache weakness diff speaking diff waking up or staying awake diff walking inapp actions diff controlling arms or legs abnormal eye movements
describes symptoms of dizziness and/or disequilibrium that arise from neck pain and issues that include cervical trauma, cervical arthritis, and other causes.

Cholesteatoma
caused by exposure to certain drugs or chemicals (e.g., intra-venous aminoglycoside antibiotics) that damage the inner-ear nerve hair cells or the vestibulo-cochlear nerve.
Ototoxicity
inflammations caused by a viral infection that can result in damage to hearing and vestibular function
Labyrinthitis; vestibular neuritis
is a sensation of rocking or movement that persists after a cruise or other form of travel.
Mal de débarquement
primary endo-lymphatic hydrops, involves abnormal-ities in quantity, composition, or pressure of the endolymph (one of the fluids within the inner ear). It is a progressive condition.
Meniere’s Disease
may be characterized by head pain with symptoms associated with vestibular impairment such as dizziness, motion intolerance, spontaneous vertigo, sensitivity to light and sound, tinnitus, imbalance, and spatial disorientation.
Migraine associated vertigo
