Invisible Effects: Chemo Brain

Ah, chemo brain: the eater of thoughts. I should note that what I’m experiencing might not just be the effects of chemotherapy messing with my brain cells. This could also be influenced by the estradiol-blocking drug Tamoxifen that is forcing me into menopause before my natural time, or it could simply be the menopause “fog” that women complain about. So I don’t know exactly what it is, besides being infuriating.

I lose thoughts in an instant. Sometimes I actually “see” them disappear in the distance. It’s such a weirdly tangible sensation. I can try to grasp at their coattails and occasionally I’m successful in latching onto the thoughts and pulling them back. Other times I need to stop and walk back through my thought processes to retrieve them. And then sometimes they’re just gone. My desk at work is covered with post-it notes as a testament to what’s going on in my noggin. If there’s something I need to do I need to write it down NOW, and it’s not unusual for me to lose the thought as I’m in the process of getting something to write it down on!

I can juggle up to three things in my mind at a time if I keep repeating them over and over again and work to maintain focus. Any more than that and it quickly crosses into the realm of hopelessness — it’s like knowing how to juggle three balls but if someone tosses a fourth at you, they all crash to the ground.

Then there are those chunks of awareness that disappear. It may simply be distraction and losing focus, but it feels like a hiccup in time that I don’t notice until it’s happened. It’s that “huh?” feeling as I return to present time when I realize that I’ve been gone for a second or two.

More disconcerting is a strange myopia that prevents me from reacting normally in a familiar situation. For instance, several months ago I treated a red light like a stop sign, and this was a familiar traffic light in my neighborhood that I’d been through many times. I briefly stopped at it, then drove through it. It was a “T” intersection that’s not terribly busy, but I did get shocked back to reality by the angry honk of a car that had the green and was probably wondering WTF I was doing. 

The bottom line is that I’m distractable beyond belief. My train of thought gets derailed before it even leaves the station. The first time I noticed this, my oncologist ordered a brain MRI, way back in February. Nope, couldn’t blame it on a brain tumor — it’s just chemo brain.

This feels demoralizing, especially since my memory used to be so good. I lament losing all those awesome thoughts and ideas. And I know they were awesome because I remember having them — I just can’t recall exactly what they were. Yeah, there will be more, but I better have a notepad nearby to write them down. I even had a better ending for this post, but, you know…
