Quiz: Multiple Sclerosis

Multiple sclerosis (MS) is a disease of the central nervous system. Symptoms can affect nearly every part of the body and mind. There is no cure, but through research we can better understand the disease.

Before taking the quiz, you can brush up on your MS knowledge here and here.

1. What type of imaging is usually used to see inflammation and damaged areas in the brain?

PET scan
MRI scan
CAT scan
X-ray
Inflamed or damaged areas in the brain are called lesions.

2. Approximately how many people have MS in the United States?

40,000
200,000
1 million
4,000
MS affects nearly 1 million people in the United States alone.

3. True or False? MS is the same for all people with the disease.

True
False
How quickly or slowly the disease progresses and when relapses occur can be unpredictable.

4. At what age is MS most commonly diagnosed?

20-40 years old
30-50 years old
40-60 years old
10-20 years old
MS is a leading cause of non-traumatic disability in young people.

5. True or False? If a person with MS does not experience symptoms, their disease is under control and not progressing.

True
False
Even in the absence of obvious symptoms, disease activity and damage to the brain and nervous system may continue in some people with MS.

6. Which symptom do nearly all people with MS experience during the course of their disease?

Tremor
Depression
Fatigue
Blurred vision
Up to 90% of all people with MS experience fatigue.

7. Inflammation and damage to what part of the body causes MS symptoms?

Muscles
Myelin
Lungs
Bones
The body’s immune system attacks myelin, the support and insulation around nerve cells, and causes inflammation and damage.

8. What usually prevents immune cells from entering the brain in healthy individuals?

The blood-brain barrier
The immune-brain barrier
Immune cells are never near the brain
The skull
The blood-brain barrier is compromised in people with MS, which allows immune cells like B and T cells from circulating blood into the brain.

9. What part of the body is not part of the central nervous system?

Spinal cord
Brain
Optic nerves
Nerves in your legs
The central nervous system (CNS) is made up of the brain, spinal cord, and optic nerves.

10. What is the most common type of MS?

Secondary progressive MS (SPMS)
Relapsing-remitting MS (RRMS)
Primary progressive MS (PPMS)
Primary relapsing MS (PRMS)
85% of people with MS are diagnosed with RRMS.
