University of Iowa researchers want to discover the cause of a medical phenomenon called "chemo brain."Despite chemo brain's prevalence, doctors do not know what exactly causes the mental fog.That's why Dr. Sneha Phadke is spearheading two new clinical trials. The first is trying to establish criteria for how to officially diagnose chemo brain.The second study looks at a potential treatment through a type of therapy. It's a novel approach to treatment with a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain.Phadke hopes the studies will lead to data that will make a difference for people experiencing the post-chemotherapy cognitive impairment."It's been hard when patients say to me, 'Do I have chemo brain?' and I can't tell them. So, what I think that it'll mean to me, is that I will be able to provide some reassurance and comfort to patients that are struggling after chemo," said Dr. Sneha Phadke, breast medical oncologist.Researchers hope to have both studies enrolled by the end of 2022.Click here or here for more information on the studies.
