Which are true regarding drugs for multiple sclerosis? (Select all that apply.)

Question

1. Drugs can cure the symptoms of MS.
2. Drugs can reverse the progressive nature of MS.
3. Drugs can reduce the inflammation of the MS attacks.
4. Drugs can prevent MS attacks on the immune system.
5. Drugs can repair the damaged axons.

Answer 1

3, 4

Rationale 1:Drugs cannot cure the symptoms of MS. Drugs treat unfavorable symptoms of the disease.
Rationale 2:Drugs cannot reverse the progressive nature of the disease. Drugs can slow the progression but not cure MS.
Rationale 3:Drugs for MS reduce immune attacks in the brain and treat unfavorable symptoms.
Rationale 4:MS drugs reduce inflammation and prevent attacks on the nervous system.
Rationale 5: MS drugs cannot repair the damaged axons. Once damaged, the axons cannot be repaired. The goal is to reduce the inflammation associated with the damaged axons.

Global Rationale: Multiple sclerosis is a disorder characterized by damaged myelin located within the CNS. Antibodies produced by the clientslowly target and destroy myelin, axonal membranes, and supporting cells of the CNS. As axons are destroyed, the ability of nerves to conduct electrical impulses is impaired. Inflammation accompanies damaged tissue, and multiple filamentous plaques called scleroses are formed. Drugs for MS reduce immune attacks in the brain and treat unfavorable symptoms. The drugs reduce inflammation and prevent attacks on the nervous system.
