ADHD in Middle and Senior years

I've not been able to read the entire collection of comments on this site. So I will, first, apologize if my topic is a redundant one. I'm looking for information on managing ADHD in the senior years. We both have concerns about the side effects and risks associated with medicating. My husband did not want to work with Adderall due to risks and the side effects experienced when he tried it at age 40. His diagnosis was "Moderate ADHD". Does someone have experience with managing ADHD in the senior years? I think it is fair to expect that things may only grow worse for us as we face the challenges of aging along with the problems ADHD creates. Thanks for any advice.
