1st one in April 2004, 2nd one September 2004,
I believe that stress brought my relapses on, my dad died 1 month to the day that my 1st relapse started, and in September we had a celebration of his life party, in my parents yard, tent, tables, caterer the whole 9 yards and that was a a HUGE undertaking with my mother becoming the most demanding person that we have ever seen!

and that is when my 2nd relapse came to visit.
Since then my life has changed alot, I don't work any more, I take an antidepressant, gone thru counseling to deal with the stress and depression and now all I do is take care of me, my house, my husband and 2 cats and shlepp my mother to her dr's appts, she has Lupus, actually my neuro said with her having Lupus, that it is not uncommon for another family member to get an immune disorder aka me and The MS
I think that PMS and even menopause, can bring relapse like feelings, I have had those feelings for about a month and finally feel better, I woke up today and instead of getting into my recliner, I read the paper, and puttered around the house. It felt good!
So to answer your question, a pattern of attacks, it did when I was stressed.
