This could lead to new therapies for neurological disorders, but will likely take several decades to do so.” candidate at Dartmouth College, added that modification “appears to be a highly regulated process which scientists could manipulate by developing drugs to target it. Epigenetics, meaning “attached to the DNA”, is the study of such modifications.Īlthough the authors could not explain how this modification occurs, Nicholas Warren, a Ph.D. Environmental factors can cause DNA to be temporarily modified, without changing the sequence, to alter how it is read. The interplay between DNA and the environment is what makes each person unique. How exactly are genetics, stress, and mental illness related? DNA, serves as instructions for cells and is broken up into functional units called genes. ![]() Modifications were most associated with genes related to a variety of mental illnesses, such as depression, autism spectrum disorder, and schizophrenia. ![]() A first link between chronic stress, genetics, and mental illness has recently observed in mice. Researchers have discovered that the genes of mice exposed to chronic stress change over time. ![]()
