I was diagnosed about 5 years ago. Although programming isn't my primary job anymore, I still do it occasionally and did so for at least a couple of years acceptably. The main thing I noticed is that the ability to focus on complex logic or chains of events went seriously downhill so I had to do a better job of sketching out my algorithm before I started to code and making lists and diagrams for myself. I could no longer hold it all in my mind. Medication (Sinemet) does help somewhat with the ability to focus. Also finding times each day when you are clear from distractions -- this can be accomplished by setting aside time to deal with the distractions and time when you will not deal with them. I find I can focus for maybe an hour at most now, and then I need a break. This is manageable when you know about it and plan around it. As I've moved to more managerial type tasks, it actually works out ok. If you intend to stick to strict programming, I advocate being as organized as possible. I used to have an excellent memory and it's just not there anymore, but I mostly do just fine because I've learned to be diligent about creating a task for myself for everything I need to do and not relying on myself to remember it. Good luck!
