Multiple Sclerosis Flashcards

1
Q
What is MS?
A
- MS is a chronic (long-lasting) autoimmune disease where the body’s immune system mistakenly attacks its own cells.
- It specifically damages the myelin, a protective coating around nerve fibers in the central nervous system (CNS).
- This loss of myelin (called demyelination) makes it hard for nerve signals to travel quickly and accurately.
2
Q
Who is affected?
A
- MS is more common in females than in males.
- Many factors, like genetics (over 200 genes) and lack of vitamin D during pregnancy, can increase the risk of MS.
3
Q
What happens in MS?
A
- Over time, the axon (the long part of the neuron) can become permanently damaged.
- This damage leads to loss of myelin and permanent symptoms, which get worse over time.
4
Q
What is the progression of the disease?
A
- MS progresses over a long period (around 20 years or more), often leading to permanent disability.
- Symptoms might come and go, meaning there can be times when the disease appears to be gone (this is called remission), but it often returns.

A
- vision problems
- difficulty walking or keeping balance
- difficulty thinking clearly
- numbness or weakness especially in the arms and legs
- muscle stiffness
