Study links stress to change in brain size Sarah Fulton
Staff Writer sarah.fulton@drake.edu
A recent study released by Yale University linked chronic anxiety and Major Depressive Disorder to a reduction in brain size. Despite studies finding decreased brain sizes for years, the new study, published in the journal “Nature Medicine,” is the first to prove a direct connection between Chronic Anxiety, the appearance of MDD and a decrease in the size of parts of the brain. Brian Sanders, a professor of psychology at Drake University, believes that any time a new “direct connection” is made, the findings are important. “Any time you can find a better idea about the precise mechanisms that are involved in the human neuropsychiatric conditions, it allows us to better understand the condition,” Sanders said. “We always want to try and understand not just that things are related, but (have) a better understanding of what is really the cause.” The study tested genes in live mice and the postmortem brains of humans both with and without depression. According to the study, the “decreased expression” of certain genes found in people with MDD is caused

by “chronic stress exposure.” Sanders said the brain is made up of cells that make connections called synapses that are responsible for certain functions. The death of these synapses is what causes the volume of the brain to shrink. “The (stress hormone) comes from the adrenal gland, and when it gets released, it goes in the blood, through the body including the brain. There are receptors in the brain for that hormone,” Sanders said. “When high levels of that (stress hormone) damage the brain, you find that receptors stop working, and that is when the brain shrinks…The (stress hormone) over long periods of time damages the brain tissue.” Kirk Bragg, a counselor at the Drake University Counseling Center, sees the correlation between anxiety and depression in the students he sees. “It would be relatively rare to have someone with significant depression who was not also anxious,” Bragg said. “I think usually it starts with anxiety. Anxiety tends to come first and depression sometimes follows.” Bragg believes that depression is the most prominent reason students come into the UCC. However, many
who are suffering from depression do not want to categorize their symptoms as such. “Sometimes students will phrase it as they are ‘stressed out’…they will not phrase it as depression, but it becomes clear that is what we are talking about,” Bragg said. According to the Yale study, MDD is seen in 17 percent of people and is “predicted to be the number two cause of illness worldwide by the year 2020.” Bragg said a true percent is “hard to pin down”, but the general statistic is that 10 percent suffer from depression, and the number is likely high in students. “I would guess that the percentage is higher here because…it is an uncertain time so the anxiety is higher,” Bragg said. “I do not think Drake’s problem is any greater than anywhere else, but certainly, the overall trend is that depression is growing.” Assistant Director of Wellness Johanna Determann believes that stress is not always negative, but many students do suffer from stress because of being overextended. “There is this pressure to always to succeed and to be

OIT hosts ‘Jubilee’ to engage students, technology Hannah Armentrout
Staff Writer hannah. armentrout@drake.edu
The Office of Information and Technology is branching out of Carnegie Hall to host its first ever “Tech Jubilee.” The technology fair will be held on Sept. 25 in Olmsted Center. The goal of the fair is to expose faculty and students to innovative ways in which technology is used in the world. The event is free and open to all members of the Drake community. The Jubilee will inform attendees about the technologies being used, free food and prizes. “I will be attending the Technology Jubilee. I think it would be interesting because there are still things I could learn about technol-
ogy,” said first-year open journalism major Delanie Downey. “The Technology Jubilee might help me as a student, because I could learn how to use technology for my betterment while having fun.” The theme for the event is “Be Curious.” The theme was inspired by the events the Mars rover, and the technological innovations involved with the success of that project. Specifically, OIT hopes to generate curiosity concerning technology. “Curiosity is what put us on Mars, and we had to develop the technology. If we weren’t curious we wouldn’t develop the technology,” said Jerome Hilscher, the learning technology specialist at Drake OIT. “Hopefully there’s
a Drake student or faculty whose curiosity is sparked at the Jubilee who will create something new.” The keynote speech by Erik Van Ommeren, the director of innovation for USA Vision, Inspiration, Navigation and Trends, which is Sogeti’s international research institute. “All three of these gentlemen (speaker) are agents for change. They’re trying to point out how things need to change. And I think that’s key,” Hilscher said. “The message is that everybody, regardless of whatever field you’re in, has to be aware of technology. You need to know what’s happening with technology because it’s go-
