What is the main pathophysiological theory for multiple sclerosis? -
ANSWERS IS- It's an autoimmune/neurodegenerative disease:
-inflammation
-demyelination/remyelination
-permanent axonal damage

Oligodendrocytes
What do T-Helper cell types 1 & 17 do? - ANSWERS IS- Pro-inflammatory
What does T-Helper cell type 2 do? - ANSWERS IS- Anti-inflammatory
What is the pathophysiology of Multple Sclerosis? - ANSWERS IS- 1.
Autoreactive T cells express Very Late Antegen-4 (VLA-4, aka α4-integrin)
on their cell surface and secrete Matrix Metalloproteinases (MMP).
2. VLA-4 binds to Vascular Cell Adhesion Molecule (VCAM) receptors on the
blood brain barrier (BBB) and MMP results in dysregulation of the BBB,
allowing cell entry into the CNS.
3. Once in the CNS, pro-inflammatory cytokines (TNF-α, INF-γ, and
Osteopontin [OP])
are secreted resulting in inflammation and further T cell entry into the CNS.
4. T cells in the CNS interact with microglia, astrocytes, and macrophages
to produce reactive oxygen species and nitric oxide causing CNS damage.
5. B cells acts as ACPs, enter the CNS, and produce myelin-specific
antibodies that form membrane attack complexes with complement
causing cell lysis.
Which disease presents in the following way:
**Visual changes, optic neuritis (Often the 1st sign/symptom)
LUMBAR PUNCTURE TEST:

Symbol Digit Modalities Test (SDMT)
What is the primary diagnostic test for MS? - ANSWERS IS- MRI with or
without contrast
What is the most common type of MS, which is involves episodes of acute
worsening with some recovery and no progression in between
exacerbations? - ANSWERS IS- Relapsing Remitting MS (RRMS)
What type of MS can develop from RRMS, have a steady progression of the
disease in between exacerbations, and present with more black holes and
brain atrophy? - ANSWERS IS- Secondary Progressive MS (SPMS)
What type of MS is the least common, it doesn't develop from RRMS and is
the progressive worsening of the disease from the start, lacking recovery
times? - ANSWERS IS- Primary Progressive MS (PPMS)
