Multiple sclerosis (MS) is not caused by a "bad nervous system" - rather, it's a condition where the immune system attacks the protective coating (myelin) around nerve fibers in the central nervous system. This causes lesions to form on nerve cells, which affects how they relay information to the brain. Regarding heredity Show Full Answer

Multiple sclerosis (MS) is not caused by a "bad nervous system" - rather, it's a condition where the immune system attacks the protective coating (myelin) around nerve fibers in the central nervous system. This causes lesions to form on nerve cells, which affects how they relay information to the brain. Regarding heredity, MS does appear to have some genetic components. Research suggests that certain genetic risk factors can be inherited from parents. However, having these genetic factors doesn't guarantee someone will develop MS - it's believed that both genetic and environmental factors play roles in its development.

There is no MS gene, that much is known. However, as detailed by @A MyMSTeam Member, if in the family, chances of getting MS are far greater than the general population.
Identical Twin risk is notable. If one twin has MS the other has a 15 to 30% chance of getting MS too.

The general population risk is 1 in 750 to 1000.

Fraternal twins have the same probability as gen pop.

No direct inheritance. But the increased probability in families is interesting and scientists are always trying to find out why.

This is the AI answer if MS is hereditary: Multiple Sclerosis (MS) is not directly hereditary, meaning it isn't passed predictably from parent to child. However, having a first-degree relative with MS, like a parent, does increase the risk compared to the general population.

For context:

In the general population, the lifetime risk of developing MS is about 1 in 330.

If a parent has MS, the risk for their child increases to approximately 1 in 672.

This suggests that while your sons' risk is higher than average, it is still relatively low. Environmental factors, lifestyle, and other genetic components also play a role in MS development.
