Aerobic exercise may prevent brain fog after chemotherapy for breast cancer

Question

Women undergoing chemotherapy for breast cancer, who also began an aerobic exercise program at the same time, reported significant improvements in both cognitive function and quality of life.

Answer 1

The author of this article continuously links direct sources which they present in their introduction. As for their actual backing of their claim, they use a study which was conducted by Jenifer Brunet, a professor at the University of Ottawa, and they summarize the main findings of the study, which were that there was no neuropsychological testing evidence that supported that aerobic exercise helped the brain. However, overall reports from participants showed that aerobic exercise decreased "brain fog". The reason why I believe that this article is not exaggerating is because of the use of the word "may" in their claim, as it does not give a guarantee that the claim is true, and they are genuine in the content of their findings. 

I was able to fine the Jenifer Brunet study on The American Cancer Study Journals website. It is a recent report and Brunet was one of the authors of the report.

Comments

I think the research you did really helped back the overall claim and your claim. It's important to trace the information back to its original source. I will say that listing multiple sources it always better to add to your evidence, but your evidence it still very strong. Also, I think addressing specific key words that adjust the connotation of the claim is a great way to look at the overall picture and what the message is.
