One thing I was not really aware of when I was diagnosed with breast cancer a little over thirteen months ago was the phenomenon patients call “chemo brain.” Even if I had been, I probably would not have put it very high on the list to worry about, compared to other symptoms and side effects. But it turned out to be a protracted, annoyingly lingering effect even after the end of chemotherapy.
It was, of course, at its peak during that treatment. The strangest thing was that I completely lost my sense of elapsed time. I am normally pretty good at estimating how much time has passed in a given subjective period, whether it’s on the scale of minutes or months. But during chemotherapy, I completely lost this ability; the feeling of time simply vanished. Everything was compressed into yesterday, today, tomorrow.
Things gradually returned to normal on this front in the months after I was done with chemo, but other symptoms continued: poor concentration, memory lapses, short attention span, inability to accomplish more than one task at a time, and this only by focusing hard. Given that I normally revel in efficiency and method, this was quite frustrating.
For the last six weeks or so, however, my powers of concentration, my mental acuity and energy have improved dramatically. I’m not back to peak performance yet, but it’s a sharp contrast with the mental sluggishness of previous months. Today I had jotted down twenty tasks on my to-do list and I have accomplished sixteen of them! Just a couple of months ago, it was a big deal to get one thing done in a day. This feels so much better, so encouraging!
