How to make my husband accept that he is suffering from ADHD?

Hey all,

We got married less than a year and we have a baby boy, 2 months old now. And we are under divorce process for all the problems and challenges that are described in ADHD marriages. I already knew that he was suffering from hyperactivity when he was young and few days ago, i came into an article about ADHD and was illuminated because it was describing exactly it all. But he refuse to accept or can i convince him just to be opened to this idea and not look as "nagging" plz.
