Women undergoing chemotherapy for breast cancer have long complained of lingering cognitive impairments after treatment. These effects are referred to as “chemobrain,” a feeling of mental fogginess. A new study from the University of Illinois reports long-lasting cognitive impairments in mice when they are administered a chemotherapy regimen used to treat breast cancer in humans.
The results are published in the journal Behavioural Brain Research.
“Cancer survival rates have increased substantially and continue to improve due to both earlier detection and better medical treatments,” said Catarina Rendeiro, a postdoctoral scholar at the Beckman Institute for Advanced Science and Technology. The study’s lead author, Rendeiro collaborated with an interdisciplinary group at Illinois, including Justin Rhodes, a professor of psychology and a Beckman Institute affiliate; and William Helferich, a professor of nutrition in the department of food science and human nutrition.
“Quality of life after chemotherapy is critically important, and chemobrain is significant in these survivors,” Helferich said.
Patient complaints and clinical observations after chemotherapy spurred an interest in chemobrain. While many researchers have examined these effects in humans as well as animals, most such studies do not assess long-term effects. The physical toll of chemotherapy is great and accounts for the short-term cognitive impairments, Rhodes said.
