Epidemiology of MS
Cause of MS is Unknown
• Inflammatory, demyelinating and
degenerative disease of the CNS
• About 350,000 people in the US, 2.5
million worldwide
• Incidence is rising
• MS is the leading cause of chronic
neurologic disability in young adults
(1:1000)
• Female : male ratio is 2:1
• Average age of diagnosis is 32, but can
occur at any age (generally 20-40);
increasingly recognized in children
Genetic

Sources of Inflammation in MS
• Immune mechanisms most likely start in the
periphery, rather than in the CNS
• Myelin-specific immune response in T cells
involves
– T and B Lymphocytes, NK cells, Macrophages,
Neutrophils, mast cells
• Immune cells gain entry to the CNS via several
mechanisms involving
– integrins, adhesion molecules, chemokines
– dynamic changes in the blood brain barrier
• Activation of microglia, astrocytes and production
of their inflammatory mediators also occur

Summary
• MS is an inflammatory, demyelinating and degenerative
disease of the CNS
– Incidence rising; leading cause of chronic neurologic disability in
young adults
DIAGNOSIS OF MULTIPLE SCLEROSIS: SYMPTOMS, MRI & PARACLINICAL FINDINGS
– Cause is unknown
• Genetic predisposition + environmental trigger  autoimmune response
– Autoimmune response
• T-cells and demyelinating antibodies from systemic circulation
enter CNS
• Release proinflammatory cytokines, stimulate other
proinflammatory mediators, trigger enhanced immune attack of
myelin
• Results in loss of myelin (demyelination) and damaged axons
(poor transmission of action potentials)
3
Clinically Isolated Syndrome
Common Symptoms of MS
• Sensory disturbances
• Most common presentations as the very first event
– Optic Neuritis
• Usually unilateral ocular/orbital pain; Blurred or total loss
of vision; Central scotoma; RAPD; Dyschromatopsia
– Myelitis
• Sensory disturbance involving affected dermatome(s);
paralysis may develop if motor pathways involved;
spasticity with abnormal reflexes; gait affected; sphincter
control difficulties may occur
• Vision impairment
• Cognitive problems
• Sexual dysfunction
• Vertigo & dizziness
• Speech problems
• Spasticity
• Fatigue
• Muscular weakness
• Bladder & bowel
problems
• Tremor
• Gait & balance
problems
– Brain Stem/Cerebellar Syndrome
• Double vision; nystagmus; ophthalmoplegia; facial
numbness and/or facial weakness; dysarthria;
dysphagia; ataxia.
• Ambulation difficulties

How is MS Diagnosed?
Mimics of MS
• Multiple Sclerosis is a clinical diagnosis
•
•
•
•
•
•
– Signs and symptoms
– Medical history
– Laboratory tests
• Requires dissemination in space and time
– Space: evidence of plaques in at least two different
locations in the CNS
– Time: evidence that plaques occurred at different
points in time
• There is no other explanation for the symptoms
Neuromyelitis optica
Acute disseminated encephalomyelitis (ADEM)
Systemic Lupus Erythematosus
Lyme disease
Neurosarcoidosis
Adrenoleukodystrophy and metachromatic
dystrophy
– Differential diagnosis to rule out other diseases and
radiographic mimics.

Coyle PK. Adv Stud Med. 2006;6(7D):s681‐s686.
Confirming the Diagnosis
Magnetic Resonance Imaging • What tests are used?
– Magnetic Resonance Imaging (MRI)
• Approximately 10% of MS cases show a normal MRI upon first presentation in
the clinic
– Visual evoked potentials (VEPs)
– Lumbar puncture (CSF)
• Clinically Isolated Syndrome (CIS) or Clinically Definite Multiple
Sclerosis (CDMS)?
– With single clinical episode and minimal MRI changes the condition is likely
to be called CIS
– CIS may also be diagnosed if there is a single clinical episode and
characteristic VEP or CSF findings (ie, presence of oligocloncal bands in
the CSF but not the serum)
– More than one episode of neurological dysfunction, “disseminated in space
and time” define Clinically Definite Multiple Sclerosis (CDMS)

Cerebrospinal Fluid (CSF) Tap
Visual Evoked Potentials (VEPs)
• CSF testing can provide evidence of chronic
CNS inflammation
– The CSF is tested for oligoclonal bands
found in 90% to 95% of patients with definite
MS
• VEPs can be used to reveal otherwise
asymptomatic demyelination
– The brain of a person with MS often responds
less actively to stimulation of the optic and
sensory nerves
• Combined with MRI and clinical data, the
presence of oligoclonal bands in the CSF but
not the serum helps facilitate a diagnosis of MS
• In conjunction with other tests, VEPs can
help elucidate the overall nerve
involvement required for a definitive
diagnosis of MS

Diagnostic Criteria
for Clinically Definite MS
2010 Revised McDonald Diagnostic Criteria
• The criteria for a diagnosis of MS have evolved over
time
• Poser criteria (19831)
– 2 attacks and evidence of separate lesions
• McDonald criteria (2001, 20052, 20103)
– Incorporated MRI, neurological history, examination,
and paraclinical laboratory examinations into
diagnosis
• Over time, changes in diagnostic criteria have
incorporated clinical advances and improvements in
imaging technology to allow for earlier diagnosis and
treatment

Summary
• Multiple Sclerosis is a clinical diagnosis
• Confirming diagnosis
– Magnetic Resonance Imaging (MRI)
– Visual evoked potentials (VEPs) used to reveal otherwise
asymptomatic demyelination
TREATMENT STRATEGIES
– Lumbar puncture (oligoclonal bands in CSF)
• 2010 Revised McDonald Diagnostic Criteria
– Requires dissemination in space and time
• Progressive disease over time
– Relapsing-remitting (RRMS)  Secondary-progressive (SPMS)
– Increasing disability (EDSS)
– Episodic inflammation
Acute MS Exacerbations (MS Relapse)
What are the Treatment Strategies?
• New neurologic symptom that last >24 hours in the absence
of a fever or infection
• Worsening of a neurologic symptom that had previously been
stable for ≥30 days
• Exacerbations can last days, weeks, or months
• At least 80% of patients with MS have an acute exacerbation
during the course of the disease
• Average acute exacerbation rate of 0.5 to 1.0 per year in the
US
• Incomplete remission from an exacerbation may result in
permanent neurologic deficit
1. Treatment of relapses (aka exacerbations,
flare-ups, attacks—that last at least 24 hours)
2. Symptom management
3. Disease modification
4. Rehabilitation (maintain/improve function)
5. Psychosocial support

Disease Modifying Therapy
General Secondary Symptoms
Treatment Recommendations for Physicians
“Initiation of treatment with an interferon beta
medication or glatiramer acetate should be
considered as soon as possible following a definite
diagnosis of MS with active, relapsing disease, and may
also be considered for selected patients with a first
attack who are at high risk of MS.”
• Prevention and Management
–
–
–
–
meclizine
Vitamin D3
Cease smoking
Involvement in physical activities
Support Groups
• Overall fewer patients with advanced disability
—National Clinical Advisory Board of the National Multiple Sclerosis Society (NMSS),
Treatment Recommendations for Physicians, Disease Management Consensus
Statement, 2008.
– Wheel-chair bound  bed ridden (EDSS 7.0 – 9.5)
• Skin care and usual DVT prophylaxis indicated in these
cases.

Patient Cases
• MS is a common neurological disorder with approximately 200 new
cases diagnosed each week
• Diagnosis of MS involves assessment of neurological symptoms, MRI
evidence, and/or laboratory tests
• Over time, diagnostic criteria have evolved to allow for earlier
diagnosis and treatment
• Because it is impossible to predict how any individual MS patient will
progress over time, initiation of treatment with an approved first-line
therapy should be considered as soon as possible following a
definitive diagnosis of MS
• Treatment response should be assessed regularly – both clinically and
radiologically
• Awareness of suboptimal response and treatment failure signs is
paramount for optimal management of MS patients
• New DMTs, including oral, are emerging. Safety considerations remain
very important in choosing DMT strategy

Case 1
• 33-year-old woman, housewife and mother of 2 children ages
4 years and 14 months, was previously healthy until June
2011 when she experienced Optic Neuritis affecting the right
eye (blurred vision, right ocular and frontal pain). She was
seen by an ophthalmologist. Symptoms dissipated gradually
without treatment in about 3 weeks.
• Since the uneventful birth of her second child in
March 2012, she has experienced unusual and
persistent overwhelming fatigue. Patient denied
bladder, bowel or sexual dysfunction.
• She was worked in by her Family Physician
(PCP) to be seen next morning. Blood work was
performed and referred immediately to a
neurologist in the same building .
• In June 2012 she acutely developed a “strange” feeling
around the neck and tingling of the legs. Although she felt a
little unsteady while walking, there was no overt motor
weakness of the lower extremities. There was no fever,
malaise or any other associated symptom.

Case 1 – Question 2
?
Case 1 Cont’d
•
How should this patient be treated for this
acute relapse?
•
•
•
1. Epidural methylprednisolone acetate suspension
injections in upper neck
2. The patient should simply be observed (no Rx)
3. Intravenous methylprednisolone pulses (1000 mg
each) for three days with or without oral taper with
methylprednisolone or prednisone
4. Oral low-dose chemotherapy
5. Extensive physical therapy without medications
Case 1 – Question 3
•
The patient has no cardiac, liver, or laboratory
abnormalities that are concerns for treatment of
her MS with chronic therapy.
The patient plans to quit smoking.
She is not sure if she will have more children.
She expressed substantial phobia to needles
and would decline injectable therapies.
?
Case 2
• 45-year-old male, trial lawyer, single. Was diagnosed
with Relapsing/Remitting MS at age 39 after he had an
episode of vertigo, double vision and ataxia. Brain MRI
showed 9 T2 lesions at that time, some enhancing after
intravenous contrast. CSF showed 3 Oligoclonal Bands.
VEP was normal. After IV steroids he was initiated on
interferon beta 1-a high dose with poor tolerance due to
persistent side effects (flu-like symptoms) leading to lack
of adherence.
Which of the treatment options is most
appropriate for the patient at this time?
1. She is a good candidate for oral fingolimod
2. Traditionally a SC interferon should be tried first
3. Occasional intramuscular injections of interferon could
be considered until the fear to needles is overcome
4. Once a month Intravenous natalizumab could be
offered as alternative
5. The patient can wait until next attack then use
glatiramer acetate
• He had a relapse at age 41 with significant leg weakness
and residual spastic gait (EDSS 3.5). His daily activities
have been substantially affected since. MRI showed
more lesions in brain and 2 in the thoracic spinal cord.
He received intravenous steroids and was switched to
glatiramer acetate daily injections.
Case 2
Last MRI Study ‐ EDSS 4.5
• Despite treatment with glatiramer acetate and
adequate adherence, the patient has continued
to have relapses about one per year with
increasing EDSS (4.5) and MRI burden of
disease. His neurologist suggests natalizumab
as second line therapy. JC Virus antibody test
ordered. The patient never has been exposed to
immunosuppressive agents.
Gd-enhancing
T2-hyperintense
Increased burden of disease
Active lesions
JC=John Cunningham virus

Case 2 Continued
Case 2 Continued
• Social: Voluntary work with the NMSS
• Habits: None
• PE:
– BP 130/78 mm Hg Wt.178 lbs. Height 5’9 (BMI=26.3)
– Normal mental status and speech.
– Mild horizontal nystagmus without diplopia. Spastic
paraparesis 4/5 with abnormal gait. Exaggerated reflexes
and bilateral Babinski signs. Decreased vibration sense
in toes.
• Labs: Periodic CBC and general chemistry with liver
function tests = normal. JC Virus Antibody test = positive.
• Medical History: Unremarkable. He had a
concussion playing football in College.
Vitamin D level was low in two separate
occasions.
• Medications: Glatiramer acetate 20 mg SC
daily; Baclofen 10 mg tid for spasticity;
Fampridine 10 mg bid for walking;
Vitamin D3 2000 IU daily.
Case 2 – Question 1

?
Case 2 – Question 2
The patient is considered for natalizumab
therapy. All of the following are reasons to
use natlizumab for second line (rescue)
therapy except:
The patient is considered for natalizumab therapy. He never
received chemotherapy but he is JCV antibody positive.
The discussion regarding risk for Progressive
Multifocal Encephalopathy (PML) should include:
1.
2.
3.
4.
Failure to tolerate a first line therapy
Failure to respond to a first line therapy
Persistent relapsing disease
Increasing disability and burden of disease
by worsening MRI
5. Absence of JCV antibodies
Case 2 – Question 3
?
1.
2.
3.
4.
Risk of > 100/1000
Risk of <1/1000
Natalizumab is generally contraindicated in this setting
The patient can be treated but therapy should be for
less than a year then resume glatiramer acetate
5. Natalizumab could be added to glatiramer acetate as
combination therapy
?
Outcomes Question #1
Which of the following criteria are required
for a diagnosis of MS?
The patient is considered for natalizumab therapy. He
never received chemotherapy but he is JCV
positive. The discussion regarding PML risk should
include which of the following?
1. A single clinical episode and characteristic visual
evoked potential (VEP) findings
2. A single clinical episode and evidence of a
plaque anywhere in the CNS
3. Evidence of plaques in at least two different
locations in the CNS and evidence that plaques
occurred at different points in time
4. Evidence of plaques in at least two different
locations in the CNS regardless of when they
developed
1. Risk increases after 25 infusions therefore closer
follow-ups and MRIs are in order
2. Current predictive data is not reliable
3. Natalizumab is the only MAB that causes PML
4. Natalizumab beneficial effects last 24 months

Outcomes Question #3
When should disease-modifying MS
therapies be initiated?
Which of the following signs indicate MS
disease progression and/or the need to
adjust disease-modifying therapy?
1. After a first attack
2. At definite diagnosis of MS with active,
relapsing disease
3. For acute exacerbations
4. For incomplete remission from acute
exacerbations
1. New T2 lesions on MRI
2. Gadolinium-negative lesions on MRI
3. No improvement in Expanded Disability
Status Scale (EDSS)
4. No decrease in frequency of relapse
