Very interesting. I was diagnosed a year ago this Saturday. My mother was diagnosed 2 months before I was and she is 23 years older than me. My neuro told me that unfortunately I hit the mother lode. 1) genetic risk since my mother has MS 2) vitamin D deficiency 3) grew up in a cold climate 4) a severe case of mono a year and a half before my diagnosis (viral trigger perhaps). Sigh.....

If there was a study I would try to have my mother sign up with me to assist with genetic research.
