Hi Emily,
I wondered the same question, and quite frankly, I was getting a little worried because I didn't return back to work until about 5 months post-op. I tried returning back to work sooner, but I just couldn't. My blood pressure shot up like crazy, and my head hurt!

I read how others (like Irene

) who had her surgery around the same time as me returned to work much sooner, and I got a little worried why I couldn't. I realized that we are all different. We had different surgeries, and we all have different medical histories. I have other medical challenges besides moyamoya which also played a big role in my recovery and the challenges I faced.
I'm now 6 months post-op and feeling better each day. I do feel a lot better since returning to work though. It keeps me busy. (As you can see, I rarely have time to come to this wonderful site!

) By the way, I didn't return to my old job. I started a new one, which made me a little worried because they know nothing about my situation and recent double bypass STA-MCA! I was (still) a little scared about trying to learn a bunch of new things that come with a new job too...but things are working out great.
Truthfully, I think I have short-term memory loss and am a little slower than I used to be. My neuro feels that I'll feel better after I stop taking Dilantin. (I'm now taking Zonegran).
Anyway, Emily, you'll know when it's the right time to return to work. For now, let your body heal...take it easy. I've learned that we're all different and so many things come in to play throughout this whole process. One thing that you've definitely got is a positive attitude...and that is a big plus! Keep it up, girl!

Hope this helps...
Take care,
Shan
