Drawing Parallels Between the Harmful Effects of Chemotherapy and Aging on the Brain Aging is an accumulation of forms of cell and tissue damage, and a complex network of downstream consequences of that damage that interact with one another to accelerate further dysfunction. It should not be too surprising to find that other approaches to producing damage in a living individual resemble aging, at least superficially. This is the case in DNA repair deficiency conditions, and, as researchers note here, it is the case in the aggressive use of chemotherapy to treat cancer. While chemotherapy can be lifesaving, it also damages DNA and leads to cognitive issues known as "chemo brain." These effects resemble the memory and learning problems seen in older adults. There are several parallels in these two situations. In both, there is decreased blood flow […]
