Relapse Remitting Multiple Sclerosis (RRMS)
Periods of acute worsening of neurologic function, with some degree of recovery. There is o
progression in between. About 85% individuals are dx with RRMS initially
How often can remissions occur in RRMS?
Remissions can be months to years with no new signs of disease activity. Deficits suffered during
attacks or exacerbation may totally resolve or result in ongoing deficits.
Secondary Progressive (SPMS)
Following an initial relapse remitting course, the disease transitions in many people to a steadily
progressive form with increased loss of function. OF the 85% who start with RRMS, more than 50%
will develop SPMA within 10 years and 90% within 25 years.
Primary Progressive Multiple Sclerosis (PPMS)
Continuing worsening of disease from onset, without distinct relapses. Approximately 10% of people
are dx with PPMS.
Progressive-Relapsing Multiple Sclerosis (PPMS)
Progressive neurologic decline with occasional acute relapses. About 5% of people appear to have
PRMS at diagnosis.
Benign MS
Patients who have rare attacks and are minimally disables 20 years after being diagnose with MS.
About 10% of MS patients experience a "benign course" of MS.
Radiologically Isolated Syndrome (RIS)
Radiologically isolated syndrome (RIS) is another early indicator of demyelination but with no
symptoms. RIS is usually detected incidentally in healthy people who have an MRI that shows typical
MS lesions. These people may remain asymptomatic (have no symptoms), or go on to develop CIS or
MS. Therefore, RIS may represent the earliest indicator of MS before symptoms appear.
Clinically Isolated Syndrome (CIS)
A term that describes a first clinical episode with features suggestive of multiple sclerosis. Usually
occurs in young adults and affects optic nerves, brainstem, or the spinal cord. They usually recover
from their presenting episode. It is often the first manifestation of MS.
Advanced Disease
Pediatric MS
, 5% of all patients with MS develop the disease before age of 18, 1% before the age of 10 years. Data
suggests IFN Beta and glatiramer acetate are safe, effective, and well tolerated I the pediatric
population.
10 year outlook for individuals with MS
(How many utilize a cane to ambulate? What percentage require a wheelchair? How man convert to
secondary progressive phase of the disease?
1/2 of patients use a cane to ambulate
15% require a wheelchair
Approximately 1/2 of patients convert to SPMS
Multiple Sclerosis Definition
The most common immune-mediated inflammatory demyelinating disease of the central nervous
system (CNS) - the brain, spinal cord, and optic nerves- and is a leading cause of disability in young
adults. It is thought that the immune system attacks theCNS.
Myelin
Coating that surrounds the nerve fibers
Axons
Carry impulses away from the cell body
Nerve Fibers
How does MS get its name?
Damaged myelin (demyelination) forms scar tissue (sclerosis) in multiple sites in the CNS.
Immune system and how it related to cause of MS
It may be the result of abnormal immune response to some infectious or environmental trigger in a
genetically susceptible individual.
The pathologic process in MS begins in MS beginning with the activation of __________in the
periphery after they are presented with a possible virus.
CD4+ T cells
What combination of cells produce an inflammatory response and subsequent myelin damage
through multiple mechanisms.
Activated CD4+ T Cells along with B Cells, macrophages, and CD 8+ T cells interact to produce an
inflammatory response.
innate immunity
Immune response to certain pathogens, which occurs in all healthy individuals and does not require
prior exposure to the pathogen. Immediate destruction of some pathogen by phagocytic cells such
as macrophage and neutrophils.
adaptive immunity
