Find a fundraising idea and donate the funds to research. Or purchase something on Amazon.com through this page and part of every sale automatically gets donated back to dysautonomia research (it doesn't cost you a penny extra, Amazon donates their share of the sale!)
There is lots happening online as well. Check out Facebook.com/DysautonomiaInternational for a daily dysautonomia factoid. I have learned SO many things I didn't know. There's also a live Tweet-A-Thon happening on October 23rd.
