Brain Scan Study Finds Evidence of ‘Chemo Brain’

Women who survive breast cancer after undergoing chemotherapy may also have to contend with impairments in attention, memory and planning skills, U.S. researchers said Monday. The research study reported that women who had undergone chemotherapy for breast cancer had significantly less activity in parts of the brain responsible for executive functioning tasks compared with breast cancer patients who were not treated with chemotherapy. Among those treated with chemotherapy, the study also found a strong correlation between women who complained they were having trouble with memory and thinking skills and actual deficits in these regions of the brain. This study may help explain why many breast cancer patients complain of “chemo brain” — a term used to describe foggy thinking and memory lapses following treatment with chemotherapy. “This is a huge validation for these women who are telling their doctors ‘something is wrong with me’,” said Shelli Kesler of Stanford University School of Medicine in California, whose study appears in the Archives of Neurology. “This shows that when a patient reports she’s struggling with these types of problems, there’s a good chance there has been a brain change,” Kesler said. Her study involved 25 breast cancer patients who had been treated with chemotherapy, 19 breast cancer patients who had surgery and other treatments, and 18 healthy women. While a finding in 25 women seems small, Kesler said it is large for a brain scan study and points to a need to start identifying, which women who undergo chemotherapy are, most vulnerable to these types of deficits.
