does multiple sclerosis skips a generation?

Answer 1

anybody could have a preexposed gene of any disease out there but it depends on the factors that trigger it. For example, M.S. could be triggered by stress or any stressfull factor or condition that plays a major role in a persons life.

Answer 2

The exact triggers for multiple sclerosis are not yet known. While there seems to be a genetic predisposition, studies have shown that even if one identical twin has the disease the other twin will not necessarily get it. Suggested triggers range from head trauma to viral infection.

My mother, her sister, and the sister's daughter have all been diagnosed with MS, so it does not necessarily "skip" a generation.

The site below is a great source of info about MS.

Answer 3

It depends on what you mean by 'skips a generation'.
Some people take this to mean that if your mother had it then you won't but your kid will. This is not true.
On the other hand, if your mother had it and you don't then your kid is still at slightly higher risk than the background.
It can skip a generation, but it doesn't strictly alternate generations. This is basically what the first responder was saying in more technical language.

Answer 4

It depends how much of multiple sclerosis the first person had. It can be generation after generation, but yes, usually skips a generation.

Answer 5

A MUST READ IF YOU HAVE MS, HIV/AIDS, CANCER, AUTOIMMUNE DISEASES,
AUTISM AND/OR CENTRAL NERVOUS SYSTEM DISORDERS:
When I was diagnosed with Multiple Sclerosis, I thought my life was
over. When they told me I had to take shots for the rest of my life, I
wanted my life to be over.
Then I found out about Low Dose Naltrexone! (LDN) No more shots! I
have my life back! I feel great!

one of the diseases listed above. If you love or know someone who has
MS, Please visit any of these free sites for more information.

Answer 6

The short answer to your question is no.

The longer answer: The average person in the US has about a 1 in 750 chance of developing MS. If you have a first-degree relative (parent, sibling, etc) who has MS, then your likelihood of developing MS drops to anywhere between one in 100 to one in 40. The likelihood of getting MS would actually get less the farther away (in degrees) you get from the person who has MS. For example, if you have a second-degree relative (a grandparent or aunt or uncle) who has MS, you have a lower likelihood of developing MS than if you have a first-degree (parent or sibling) relative who has MS. Therefore, the notion of "skipping a generation" is not supported by the statistics.
