|
the quick oscillation; the shaking of the eyeballs |
Nystagmus |
|
The exact etiology of MS is |
Unknown (idiopathic) |
|
MS Hallmark: |
plaque formation in MRI |
|

Dec vitamin D level |
|
Multiple sclerosis risk factor: |
• F>M • 20-40years old • High SES (temperatecountries) • Dec vitamin D level • Smoking • Family History |
|
Multiple sclerosis etiology: |
1. The exact etiology is Unknown (idiopathic) 2. Viral, autoimmune 3. Mixed histocompatibility complex (MHC/HLA-6) region of chromosome 6 |
|
Multiple sclerosis chromosome |
chromosome 6 |
|
Multiple sclerosis risk factor: race |
white population northern america northern europe scandinavian countries (sweden, denver) new zealand southern australia southern canada |
|
Multiple sclerosis aka |
the great crippler of young adult |
|
a chronic inflammation, demyelinating disease of the CNS characterized by the segmental demyelination, inflammation & gliosis |
Multiple sclerosis |
|
plaque formation (hallmark) |
gliosis |
|
Multiple sclerosis accepted theories: |
1. autoimmune disease induced by a viral or other infections aent a. herpes viruses (type 1,2,6) b. familial? pneumonia 2. genetics |
|
demyelination of the PNS |
GBS |
|
proliferation of the neuroglial cell or tissue within the CNS & results in glial scars (plaque) |
gliosis |
|
best diagnosis for MS: |
MRI |
|
best diagnosis for TBI: |
CT scan |
|
demyelinated areas eventually become filled with fibrous astrocytes (most abundant glial cell) & undergo a process called gliosis |
Multiple sclerosis |
|
demyelinating lesion in the white matter of the CNS |
Multiple sclerosis |
|
Plaque locations in Multiple sclerosis; |
POBCCCC Periventricular white matter Optic Nerve (CN 1) Brainstem Cerebral cortex/cortex CST Cerebellum (cerebellar peduncle) Cervical spinal cord (posterior white column)

Four Major Clinical Subtypes of MS |
1. Relapsing-Remitting MS (RRMS) 2. Secondary-Progressive MS (SPMS) 3. Primary-Progressive MS (PPMS) 4. Progressive-Relapsing MS (PRMS) |
|
Characterized by discrete attacks of neurological deficits (relapse) with either full or partial recovery (remission) in subsequent weeks to months. |
Relapsing-Remitting MS (RRMS) |
|
Affects approximately 85% of patients with MS at diagnosis |
Relapsing-Remitting MS (RRMS) |
|
MC MS type: |
Relapsing-Remitting MS (RRMS) |
|
Characterized by an initial relapsing-remitting course, followed by a change in clinical course with progression to steady and irreversible decline with or without continued acute attacks |
Secondary-Progressive MS (SPMS) |
|
The majority cf patients with RRMS progressed to SPMS |
Secondary-Progressive MS (SPMS) |
|
>50% of type of MS: |
Secondary-Progressive MS (SPMS) |
|
20% out of the 85% of RRMS |
Secondary-Progressive MS (SPMS) |
|
Characterized by disease progression and steady functional decline from onset |
Primary-Progressive MS (PPMS) |
|
Patients may experience modest fluctuations in neurological disability but discrete attacks do not occur (without acute attacks) |
Primary-Progressive MS (PPMS) |
|
is associated with later onset (mean age 40 years)and more equal gender distribution |
Primary-Progressive MS (PPMS) |
|
Affects approximately 10% of patients with MS |
Primary-Progressive MS (PPMS) |
|
type of MS that is associated with later onset (40 y.o) |
Primary-Progressive MS (PPMS) |
|
type/s of MS that has bad prognosis: |
Secondary-Progressive MS (SPMS) Primary-Progressive MS (PPMS) |
|
type/s of MS that has good prognosis: |
Relapsing-Remitting MS (RRMS) |
|
types of MS according to severity: |
benign MS malignant MS |
|
disease in which the pt. remains fully functional in all neurological system 15 years after onset |
benign MS |
|
aka "marburg's disease" |
malignant MS |
|
rapid onset & almost continual progression leading to significant disability or death with a relatively short time period after onset |
malignant MS |
|
• Characterized by a steady deterioratiorn in disease from onset (similar to PPMS) but with occasional acute attacks |
Progressive-Relapsing MS (PRMS) |
|
Intervals between attacks are characterized by continuing disease progression |
Progressive-Relapsing MS (PRMS) |
|
• Affects approximately 5% of patients with MS |
Progressive-Relapsing MS (PRMS) |
|
least common type of MS |
Progressive-Relapsing MS (PRMS) |
