1
Q

CN 1 Olfactory (+) test =

A

(+) = anosmia (inability to detect smells)

2
Q

Cn II visual fields (+) test =

A

(+) = Monocular visual loss (visual field deficits)

3
Q

CN II (afferent)/III (efferent) Pupillary response (+) test =

A

(+) = Absence of pupillary response and/or presence of unequal pupils (anisocoria)

4
Q

CN III/IV/VI EOMS, Pursuit Eye movements (+) test =
Gaze palsy = (UMN/LMN)
Deconjugate gaze = (UMN/LMN)

A

(+) = presence of 2 or more saccades, strabismus, impaired eye movements, double vision
Gaze palsy = both eyes limited in same direction
-central or UMN lesions
Deconjugate gaze = one eye or both eyes limited in different directions
-LMN lesion or problem at NMJ

5
Q

If Trochlear (IV) deficit you will see

A
  • Palsy - downward or torsional movement weakness
  • Affected eye will drift up at rest
  • Double vision with downward smooth pursuits
  • Present at rest with head tilted to one side and chin tucked
6
Q

If Abducens (VI) deficit you will see

A
  • Palsy - lack of complete lateral eye movement

- At rest, eye will cross inwards toward nose (astropia)

7
Q

CN V Sensation (motor mastication/sensation face) (+) test =

A
  • motor mastication + test = Weakness/deviation of jaw to ipsilateral side when opened
  • sensation face (+) test = Loss of facial sensation of numbness
8
Q

CN VII Facial Symmetry and Expression (+) test =
If just muscles of lower face (UMN/LMN?)
If muscles of entire face (UMN/LMN?)

A

(+) test = presence of weakness or paralysis
If just muscles of lower face = UMN
If muscles of entire face = LMN

9
Q

How to CN VIII 1st Test =

A

Test for hearing loss with finger rub next to ear

10
Q

If abnormalities in 1st Test CN VIII do -
Normal =
Conductive hearing loss =
Sensorineaural hearing loss =

A

Weber test - lateralization of sound
Normal = hear tuning fork placed on top of head in both ears
Conductive hearing loss = sound heard louder in affected ear
Sensorineaural hearing loss = sound heard louder in unaffected ear

11
Q

If Weber test positive, do -
Normal =
Conductive hearing loss =
Sensorineaural hearing loss =

A

Rinne Test - tuning fork on mastoid process, and then move to ear
Normal = hearing sound longer through air than the bone
Conductive hearing loss = sound heard through bone equal to or longer than air
Sensorineaural hearing loss = unable to hear when tuning fork is on the mastoid

12
Q

CN IX/X Palatal and Pharynx Control (+) test =

A

(+) = deviation of palate and uvula to uninvolved side

13
Q

CN X Gag reflex (+) =

A

(+) = absence of gag reflex

14
Q

CN XI Neck motor function (+) test =

A

(+) = weakness on same side of lesion

15
Q

CM XII Tongue Movement (+) test =
LMN
UMN

A

(+) LMN = Tongue deviation towards weak side with atrophy or fasciculations
(-) UMN = Tongue deviation towards strong side
