Chemo brain

I often wonder how many brain cells chemo has killed. Seems lately I have ADHD. Can't seem to concentrate on one thing and many times go to do something like go to Google and think...what am I looking for?

I write things down constantly at work, becuase someone will tell me something, and they'll walk out of my office, and with them goes my memory of what they told me to do.

I don't know if it's reversable or if it gets better. I guess Ignorance is Bliss....
