Hi Leilasmom - yes, absolutely. In fact, I posted a question about this same thing, but it's buried deep in another thread.
My very first attack was preceded by a huge emotional event and I have always felt there's a connection. It involved a broken heart, feeling unable to love or be loved, and a lot of fear. I could say terror, actually.
I think it's important to recognize that every emotion we feel releases chemicals - neurotransmitters and hormones and such - into our systems that affect the entire body. Although we tend to discount it and try to stay in control all the time, emotion is vital information about who we really are.
We can't help how we feel - we don't choose our feelings, we just get them, and there is always a good reason for the way we feel. It may not be a rational reason, but it is real for us.
For me, opening my heart to love is part of dealing with SCLS. Whether it ever effects my body physically or not, it is worth the struggle.
I guess I'm saying I think the emotion effects the body, rather than SCLS causing the emotion. I don't know if this provides you any insight, but I do hope it helps and wish you and Leila the best of luck :-)
