1. What are abnormal findings for Cranial Nerve I (Olfactory)?
Correct Answer: Loss of smell (anosmia)
1. Anosmia can result from head trauma, nasal obstruction, neurodegenerative disease (Parkinson,
Alzheimer), or COVID-19.
2. Unilateral loss is more concerning than bilateral for mass lesions (olfactory groove
meningioma).
2. What are abnormal findings for Cranial Nerve II (Optic)?
Correct Answer: Visual field defect, blurred vision, blindness
1. CN II assessment includes visual acuity, visual fields by confrontation, and funduscopic exam.
2. Abnormal findings may indicate optic neuritis, glaucoma, retinal disease, or brain lesions
affecting optic pathways.
3. What are abnormal findings for Cranial Nerve III (Oculomotor)?
Correct Answer: Ptosis, anisocoria (unequal pupil size), diplopia, dilated pupil, inability to move eye
in certain directions
1. CN III controls most EOMs (superior, medial, inferior recti; inferior oblique), pupil
constriction, and eyelid elevation.
2. CN III palsy causes "down and out" eye position, ptosis, and dilated pupil (if compressive
lesion).
4. What are abnormal findings for Cranial Nerve IV (Trochlear)?
Correct Answer: Vertical diplopia, difficulty looking downward and inward (double vision)
1. CN IV innervates the superior oblique muscle which depresses and intorts the eye.
2. Patients with CN IV palsy may tilt their head away from the affected side to compensate for
diplopia.
5. What are abnormal findings for Cranial Nerve V (Trigeminal)?
Correct Answer: Loss of face sensation, facial pain (trigeminal neuralgia), difficulty chewing
1. CN V has sensory (face) and motor (masseter, temporalis) components.
2. Trigeminal neuralgia causes severe, lancinating facial pain triggered by touch or chewing.
, 6. What are abnormal findings for Cranial Nerve VI (Abducens)?
Correct Answer: Cannot abduct eye laterally (double vision)
1. CN VI innervates the lateral rectus muscle. Isolated CN VI palsy is common in increased ICP,
diabetes, or microvascular disease.
2. Vision is binocular horizontal diplopia worse when looking toward the affected side.
7. What are abnormal findings for Cranial Nerve VII (Facial)?
Correct Answer: Facial droop, cannot close eye, loss of taste (anterior 2/3 tongue), decreased saliva
1. Peripheral CN VII palsy (Bell's palsy) affects entire half of face including forehead.
2. Central (upper motor neuron) lesion spares forehead due to bilateral innervation.
8. What are abnormal findings for Cranial Nerve VIII (Acoustic/Vestibulocochlear)?
Correct Answer: Hearing loss, tinnitus, balance issues
1. Rinne and Weber tests distinguish conductive from sensorineural hearing loss.
2. Unilateral sensorineural loss with tinnitus may indicate acoustic neuroma.
9. What are abnormal findings for Cranial Nerve IX (Glossopharyngeal)?
Correct Answer: Decreased gag reflex, loss of taste (posterior 1/3 tongue), trouble swallowing
1. CN IX is tested with gag reflex and swallowing assessment.
2. Isolated CN IX palsy is rare; usually tested with CN X together.
10. What are abnormal findings for Cranial Nerve X (Vagus)?
Correct Answer: Hoarse voice, dysphagia, uvula deviates away from lesion
1. CN X damage causes ipsilateral vocal cord paralysis, dysphagia, and palatal droop.
2. Uvula deviates away from the affected side.
11. What are abnormal findings for Cranial Nerve XI (Spinal Accessory)?
Correct Answer: Weak shoulder elevation (trapezius) and head turning (sternocleidomastoid)
1. Assess CN XI by asking patient to shrug shoulders (trapezius) and turn head against resistance
(SCM).
2. Weakness suggests peripheral nerve injury or central lesion.
12. What are abnormal findings for Cranial Nerve XII (Hypoglossal)?
Correct Answer: Dysarthria (trouble speaking), tongue atrophy, deviation of tongue to one side
1. Tongue deviates toward the side of the lesion.
2. Assess by asking patient to stick out tongue and move side to side.
