Both Parties with ADHD...Has anyone survived?


I'm new and am thrilled to have found a site with so many helpful resources and such valuable information!  Please forgive my newbiness if this isn't the correct place to ask ... but most of the information I've seen so far relates to relationships between a person with ADHD and one without ADHD.  Are there simply not very many relationships where both partners have ADHD or were there simply no survivors?
