Cancer Survivors Finally Have Proof That Chemo Brain Is Real. Here’s What Researchers Are Saying…

But now researchers are putting this symptom, which has been presented mainly in the form of anecdotal evidence up until now, up to rigorous scientific testing – and what they’ve found is that patients aren’t exaggerating: “chemo brain” is very much a real thing.

Study Details

The study, published in the journal Clinical Neurophysiology and funded by the Canadian Breast Cancer Foundation, took place at the University of British Columbia in Vancouver, Canada.

Breast cancer survivors were tasked with completing a series of simple activities, while researchers monitored their brain activity. To their surprise, they found that people with “chemo brain” were indeed incapable of sustaining focused thought(2).

Healthy Brains Versus Chemo Brains

Healthy brains function in a cyclical fashion – people alternate between being focused and engaged in the task at hand, and letting their mind wander once the task is completed.

But the University of British Columbia researchers found that those suffering from “chemo brain” tended to stay in a disengaged state, unable to maintain sustained focus on a task at hand. This was true even when the cancer survivors thought they were focusing on a task.

“A healthy brain spends some time wandering and some time engaged,” said Todd Handy, a professor of psychology at UBC. “We found that chemo brain is a chronically wandering brain, they’re essentially stuck in a shut out mode.”

Interestingly, the brain activity of patients suffering from “chemo brain” tended to more closely resemble the brain activity of healthy patients when they were asked to relax and let their minds wander, indicating that “chemo brain” patients may be more focused on their inner world than on external tasks.
