c. days

Answer 2

a. minute

Question 3

A lady with a history of migraine, presenting with visual disturbances without other
problems. Her sister had breast carcinoma. The lady suddenly developed ataxia,
nystagmus, vertigo, wide gait and occipital headache while walking after exercise
last week:
a. MS
b. atherosclerotic cerebellar infarction
c. vertebral artery dissection
d. cerebellar metastases

Answer 3

b. atherosclerotic cerebellar infarction

Question 4

What is the most reliable way to distinguish peripheral vertigo from central vertigo?
a. horizontal nystagmus with rotator component
b. negative oculovestibular reflex in central vertigo

Answer 4

b. negative oculovestibular reflex in central vertigo

Question 5

Nystagmus resulting from vestibular dysfunction is characteristic during the DixHallpike manoeuvre:
a. is quickly exhausted
b. shall not be exhausted
c. is vertically oriented

Answer 5

a. is quickly exhausted

Because it’s peripherical

Question 6

What is the most common cause of paroxysmal positional vertigo?
a. Meniere’s disease
b. benign paroxysmal positional vertigo
c. vestibular neuronitis
d. the shvanom of the statoacusticus

Answer 6

b. benign paroxysmal positional vertigo

Question 7

How can we distinguish positional vertigo of central cause from peripheral cause
using the Dix-Hallpike manoeuvre?
a. no latency in central vertigo, nystagmus is not exhausted after repeated
testing
b. central vertigo has latency, nystagmus is exhausted after repeated testing
c. central vertigo has latency, nystagmus is not exhausted
d. no latency in central vertigo, nystagmus is exhausted

Answer 7

a. no latency in central vertigo, nystagmus is not exhausted after repeated
testing

Question 8

Nystagmus is not peripheral in origin if it is:
a. horizontally-rotating
b. skew deviation present
c. vertical
d. associated with a change in head position
e. more pronounced in gaze fixation

Answer 8

b. skew deviation present
e. more pronounced in gaze fixation

Question 9

The rapid component of nystagmus points towards:
a. intact peripheral vestibular apparatus
b. affected peripheral vestibular apparatus
c. cerebral hemispheres affected
d. unaffected cerebral hemispheres
e. unaffected cerebellar hemispheres

Answer 9

a. intact peripheral vestibular apparatus

Question 10

The characteristics of nystagmus in benign paroxysmal vertigo of peripheral origin are:
a. no latency and no exhaustion
b. has latency and is exhausted
c. has no latency and is exhausted
d. has latency and is not exhausted
e. none of the above

Answer 10

b. has latency and is exhausted

Question 11

Peripheral nystagmus is characterised by:
a. can be oriented vertically
b. associated with skew deviation
c. is constant
d. not associated with a change in head position
e. occurs in different directions

Answer 11

d. not associated with a change in head position
