Multiple Sclerosis - Summary

Multiple Sclerosis (MS) is an autoimmune-mediated neurodegenerative disease of the central nervous system
 • Inflammatory demyelination with axonal transection.  
 • Results in physical disability, cognitive impairment, decreased quality of life

Multiple Sclerosis Epidemiology:
 • Female to male sex distribution of nearly 3:1
 • MS typically presents in young adults (mean age of onset, 20-30 years)

Presentation - Young adults aged 20 to 30 years with:
 • Unilateral optic neuritis
 • Partial myelitis
 • Sensory disturbances
 • Or brainstem syndromes such as internuclear ophthalmoplegia

Atypical Fulminant Forms of MS:
 • Tumor-like large multifocal demyelinating lesions:
 • Tumefactive demyelination
  • Balo’s concentric Sclerosis
  • Marburg Variant

Examination:
 • UMN signs (Hyperreflexia, Clonus, Babinski’s sign)
 • Uhthoff’s phenomena
 • Lhermitte’s sign
 • Internuclear ophthalmoplegia
 • Afferent pupillary defect

SIGNS/SYMPTOMS:
 • CENTRAL: Fatigue, Depression, Cognitive impairment, Mood disorder
 • MUSCULOSKELETAL:, Spasm, Cramping, Weakness, Ataxia
 • GU: Frequent urination, Incontinence
 • VISUAL: Nystagmus, Optic neuritis, Diplopia
 • MOUTH: Slurring/Stuttering speech, Dysphagia
 • GI: Constipation, Diarrhea, incontinence
 • SENSES: Tingling, Burning, Paresthesias, Sensitivity to pain, Trigeminal neuralgia

Multiple Sclerosis Diagnosis - Based on a combination of:
1. Signs and symptoms
2. Radiographic findings (eg, magnetic resonance imaging [MRI] T2 lesions) McDonald diagnostic criteria for MS
3. Laboratory findings (eg, cerebrospinal fluid-specific oligoclonal bands)
   - Oligoclonal bands are found in up to 95% of patients with clinically definite MS
4. VEP’s: EEG of visual stimulation

Clinical Course of Multiple Sclerosis:
 • Relapsing-remitting MS (FLARE) (85% of pts)
	→ Enter a period of progressive decline
	→ Secondary Progressive MS
 • Primary Progressive MS (Spinal cord predominant) (15% of pts)
	→ Steady decline without flares

Multiple Sclerosis Treatment:
 • Functionally disabling symptoms with objective evidence of neurologic impairment (Loss of vision, Diplopia, Weakness, and/or cerebellar symptoms)
 • Acute: 
	- IV methylprednisolone 500 to 1000 mg daily 3-5 days
	- Oral prednisone (1000 mg to 1250 mg) without an oral taper 3-7 days
	- Short course of intramuscular adrenocorticotropin hormone gel
 • Refractory Relapse: Plasma exchange (PLEX) or IVIg
