Chemotherapy and its influence on the brain

Chemotherapy, when some individuals are being subjected to chemotherapy, usually over time notice changes in memory, concentration, and the way they think.

The first such cases were observed in women with breast cancer who had undergone treatment chemotherapy, for many years, many patients were concerned, joking and frustrated by these "mental haze" that came with what they called "chemo-brain". For the first time, scientists were able to show that the "chemo-brain" had real consequences.

Study published in the journalClinical Neurophysiologyhas revealed that people who have experienced such a "kemo-brain" state lack the ability to maintain the focus of their own thoughts. "A healthy brain spends some time on wandering, but it is also fully involved for a while.

We've found that chemo-brain is chronically wandering, he's actually constantly excluded, "said Todd Handy, a professor of psychology at British Columbia University.

Scientists have found that those with "kemo-brain" tend to stay in such a state.

This is why 50% of patients who thought they would be affected by this situation felt the need to constantly write down and perform just the simplest possible tasks.

During the study, scientists used electroencephalogram (EEG) to monitor the cerebral activity of patients suffering from crayfish breastfeeding while performing a series of tasks. They found that the patients were cured of breast cancer had a less probability of keeping on-going attention than healthy people - even up to three years after treatment.

What is even worse is the fact that when women thought they were concentrated, the EEG showed that a large part of their brain was actually turned off and their mind wandered.

The study also showed that their brains were more active than the brains of healthy women even when they were asked to relax. Scientists hope that these results can help doctors measure the effect that chemotherapy it's on the brain of patients.

Current tests to assess the cognitive ability of patients receiving chemotherapy have been developed for other cognitive disorders, such as Alzheimer's disease or various brain injuries. They proved to be ineffective because cancer patients were often able to complete these tests without any problems.

"Physicians now acknowledge that the effects of cancer chemotherapy treatment are visible for a long time after their completion, and can really have a major impact on the life of a person. These results could offer a new way to test the 'hemo-brain' in the patient, and monitor their condition, "said Kristin Campbell, lead author of the study.
