Q

What is the pathophysiology or events (7) that take place with MS?

A
  1. immune response (to virus) triggers activation of immune cells
  2. cells activate autoantigens, producing cytotoxic effects within CNS “friendly fire”
  3. Phagocytic activity of macrophages may also contribute to demyelination
  4. demyelination slows neural transmission and causes nerve to fatigue rapidly
  5. Acute inflammatory event emerges (edema and infiltrates surround the acute lesion, can cause mass effect further interfering with nerve conduction)
  6. During early stages of MS, oligodendrocytes survive and can produce remyelination.
  7. Demyelinated areas become filled with fibrous astrocytes and undergoes gliosis. (this glial scare or plaque is a permanent change)

Q

What is gliosis?

A
  • proliferation of neuroglial tissue within the CNS resulting in glial scars (plaques)
  • axon itself becomes interrupted and undergoes neurodegeneration
  • this is the main cause of permanent disability

Q

What are the four major clinical subtypes of MS?

A
  • Relapsing-Remitting MS (about 85% of MS at diagnosis, lack of disease progression between periods of relapse)
  • Secondary-Progressive MS (begins with RRMS course, followed by steady irreversible decline)
  • Primary-Progressive MS (continuous worsening of disease, without discrete attacks)
  • Progressive-Relapsing MS (steady deterioration from onset with occasional acute attacks)

26
Q

T/F - both new damage and old damage to the CNS can be seen in the same MRI?

A

true - highly sensitive to plaques in while matter (new active inflammation with in 6 weeks are bright spots and long term disease is seen as black holes.

27
Q

Other than MRI’s what other laboratory test are use with MS patients and why (2)?

A
  • lumbar puncture for immunoglobulin (IgG) in CSF is a response to demyelination (PPMS have higher levels than RRMS)
  • evoked potentials (nerve conduction test) 90% of MS pt’s have abnormal EP (basically slowed nerve conduction)
28
Q

What drug(s) are used to manage acute relapse or episodes?
