Why is it important to learn about MS
❖ As of 2010 prevalence of MS in US is the highest ever reported, with 727,344 reported cases. (1)
❖ Primary care providers or other subspecialty providers are often the first physician that MS patients present to.
❖ Early diagnosis is important as early initiation of treatment may prevent disability (2).

Defining Multiple sclerosis
❖ MS : Immune mediated chronic disease of central nervous system which causes multiple attacks on CNS separated by time and space.
❖ Clinical attack/relapse/exacerbation/CIS (when it is first relapse) : Patient reported new symptoms or objectively observed signs typical of an acute inflammatory demyelinating event in the CNS, current or historical, with duration of at least 24 hours in absence of fever or infection, with complete or partial recovery of symptoms.
❖ Pseudo exacerbation: Recurrence of symptoms experienced before in setting of infection, stress, physical exortion or heat exposure.
❖ Silent attack : appreciated on MRI

Symptoms: other phenotypes of MS
❖ Clinically Isolated syndrome: One demyelinating event
• 60-70% of CIS patients develop MS in 20 years(1)

Why is it important to learn about management of MS
1. Disease modifying therapies has side effects and compliance issues.
2. Symptom management is utmost important from patient’s perspective, which requires multidisciplinary approach.
3. Important role of vitamin D in treatment of MS.
4. Role of smoking in progression of MS.
5. Importance of treating medical comorbidities in MS patients.
6. Social and financial issues.

Treatment of MS relapse
❖ First identify if it is relapse (typically a new symptom) or pseudo relapse (recurrence of old symptom in setting of infection or stress).
❖ Rule out infection and metabolic causes first. UTI is common mimicker of MS relapse.
❖ High dose IV steroid (1gm methylprednisonlone daily) for 3-5 days (1,2)
❖ Can consider equivalent dose of oral steroid (1250 mg prednisone per day) for 3-5 days (3, 4)
❖ IV IG and Plasma Exchange if no response to steroid

❖ Smoking is a significant risk for development of MS with overall odds ratio of 1.25-1.51.
❖ Cessation of smoking at the diagnosis of MS can delay conversion to secondary progressive stage.
