After chemo I had some pretty drastic cognitive and memory impairment. I started with crosswords, (very helpful) and also did logic puzzles. Even things like Where’s Waldo type activities helped with focus and control. I got Games magazine every month, and sometimes just figuring out how to do the things was challenging. I like crosswords the best, but I still do all those other things from time to time. Back then, doing those things helped bring me back. I’ll never recover my full mental capabilities, but it’s so much better than my post-chemo fog!
