Although the causes and existence of post-chemotherapy cognitive impairment have been a subject of debate, recent studies have confirmed that post-chemotherapy cognitive impairment is a real, measurable side effect of chemotherapy that appears in some patients.[2] While any cancer patient may experience temporary cognitive impairment while undergoing chemotherapy, patients with PCCI continue to experience these symptoms long after chemotherapy has been completed. PCCI is often seen in patients treated for breast cancer, ovarian cancer, prostate cancer, and other reproductive cancers,[2] as well as other types of cancers requiring aggressive treatment with chemotherapy.[4][5]
