Had Chemo and Can't Find Your Words? You're Not Alone.

You know it's just on the tip of your tongue. It's a word that has a "ka" sound in the beginning and a "tah" sound somewhere at the end. And you can almost see it, but then darn, it's gone. Perhaps later, when you're rushing to slap dinner on the table, that stupid word, so maddeningly elusive just hours before will pop right into your head, as if it were all just some silly misunderstanding between you and your brain.

I'm guessing that if you've had chemo and have experienced the fog that often follows, then you know what I'm talking about, right? It's not that you can't comprehend language, it's that you can't retrieve it. It's like the arcade game where you maneuver levers to grab a prize. You just can't get the prongs low enough or tight enough around that plastic key chain before it slips away.

In a 2006 study of the side effects experienced by 26 women undergoing chemotherapy for breast cancer, language (including fluency, verbal repetition, reading, and writing to dictation) was the most severely affected cognitive function, followed by memory. (Source: F. Downie, Psycho-Oncology 15 -2006: 921-930). That's not entirely surprising considering that chemotherapy not only may affect language but the speed in which we process information.

One woman I interviewed for "Your Brain After Chemo" had this to say: "It is painful when people look at me with confusion while I am trying to talk. I know that I'm not making sense, and I don't know how else to talk. When it happens I die a million deaths and feel very dumb."

Have you experienced word retrieval problems during or following chemotherapy? Have you found ways to compensate? If so, please share what has worked for you.
