What is Multiple Sclerosis?

An autoimmune disease where genetic and environmental factors may play a role in its cause.

What happens to the myelin sheath in Multiple Sclerosis?

Myelin undergoes demyelination → multiple areas harden into plaques → interfere w/ signal propagation.

The myelin sheath undergoes demyelination, with multiple areas hardening into plaques, which interferes with signal propagation.

The myelin sheath undergoes demyelination, with multiple areas hardening into plaques, which interferes with signal propagation.

How does Multiple Sclerosis affect the myelin sheath?

Cytotoxic T cells attack the myelin, leading to the formation of plaques and disrupting normal nerve signal transmission.

What are the common symptoms of Multiple Sclerosis?

Symptoms include blurred vision, muscle weakness, ataxia (lack of muscle coordination), and fatigue.

What treatments are used for Multiple Sclerosis?

Immunosuppressant drugs, such as interferons, are commonly used to manage the disease.
