My ex-husband was diagnosed at about age 53. Initially, he seemed enchanted by the diagnosis, but that dissipated. He seemed to like taking the medications; he was okay with talk therapy; he put very little effort into making behavior changes other than taking the medications. So I would say the diagnosis at best had a neutral effect and at worst, was negative. How about you? Feel free to respond whether you're a "non" or a person with ADHD. Thanks.
