MULTIPLE SCLEROSIS
1. Question:
Which of the following is the most common presenting symptom of multiple sclerosis (MS)?
A. Seizures
B. Cognitive impairment
C. Optic neuritis
D. Muscle wasting
✅ Correct Answer: C. Optic neuritis
📝 Explanation:
Optic neuritis—characterized by painful vision loss—is a common early symptom of MS due to
demyelination of the optic nerve. Though other symptoms may appear later, optic neuritis often
triggers the initial diagnosis.
2. Question:
Which MRI finding is most specific for diagnosing MS?
A. Lesions in the cerebellum only
B. Ring-enhancing lesions
C. Dawson’s fingers
D. Periventricular hemorrhage
✅ Correct Answer: C. Dawson’s fingers
📝 Explanation:
Dawson’s fingers are ovoid lesions perpendicular to the ventricles, seen on MRI, and are highly
characteristic of MS, indicating perivenular demyelination.
3. Question:
Which of the following disease-modifying therapies (DMTs) is administered via subcutaneous
injection?
A. Natalizumab
B. Glatiramer acetate
,C. Fingolimod
D. Ocrelizumab
✅ Correct Answer: B. Glatiramer acetate
📝 Explanation:
Glatiramer acetate (Copaxone) is administered subcutaneously and is used for relapsing-
remitting MS. Natalizumab and ocrelizumab are IV infusions; fingolimod is oral.
4. Question:
Which of the following is a primary progressive form of multiple sclerosis?
A. One that begins with relapses and remissions
B. One that never remits and gradually worsens from the start
C. One that follows an infection
D. One associated only with sensory deficits
✅ Correct Answer: B. One that never remits and gradually worsens from the start
📝 Explanation:
Primary Progressive MS (PPMS) is defined by gradual neurologic decline without distinct
relapses or remissions.
5. Question:
Which of the following lab findings is most suggestive of MS in cerebrospinal fluid (CSF)?
A. Low glucose
B. High neutrophils
C. Oligoclonal bands
D. Elevated lactate
✅ Correct Answer: C. Oligoclonal bands
📝 Explanation:
Oligoclonal bands (OCBs) in the CSF indicate immune activity within the CNS, found in
about 85–95% of MS patients, and are a key diagnostic criterion.
6. Question:
What is Uhthoff’s phenomenon?
, A. Inflammation of the spinal cord
B. Pain with eye movement
C. Worsening of symptoms with heat or exercise
D. A type of seizure in MS
✅ Correct Answer: C. Worsening of symptoms with heat or exercise
📝 Explanation:
Uhthoff’s phenomenon refers to temporary worsening of MS symptoms with increased
body temperature, such as during exercise, fever, or hot weather.
7. Question:
What is the main mechanism of action of fingolimod?
A. Blocking B-cell activation
B. Stimulating remyelination
C. Sequestering lymphocytes in lymph nodes
D. Inhibiting TNF-alpha
✅ Correct Answer: C. Sequestering lymphocytes in lymph nodes
📝 Explanation:
Fingolimod (Gilenya) is a S1P receptor modulator that prevents lymphocytes from leaving
lymph nodes, thus reducing immune attack on the CNS.
8. Question:
Which test is used to evaluate visual pathway involvement in MS?
A. EEG
B. Visual evoked potential (VEP)
C. CT scan
D. Spinal tap
✅ Correct Answer: B. Visual evoked potential (VEP)
📝 Explanation:
VEP testing measures slowed conduction in the visual pathways, often present in MS even
when optic neuritis is subclinical.
9. Question:
