Rutgers scientists say learning new cognitive skills can help reduce overwhelming negative thoughts

Meditation and aerobic exercise done together helps reduce depression, according to a new Rutgers study.

The study, published in Translational Psychiatry this month, found that this mind and body combination - done twice a week for only two months - reduced the symptoms for a group of students by 40 percent.

"We are excited by the findings because we saw such a meaningful improvement in both clinically depressed and non-depressed students," says Brandon Alderman, lead author of the research study. "It is the first time that both of these two behavioral therapies have been looked at together for dealing with depression."

Alderman, assistant professor in the Department of Exercise Science, and Tracey Shors, professor in the Department of Psychology and Center for Collaborative Neuroscience, both in the School of Arts and Sciences, discovered that a combination of mental and physical training (MAP) enabled students with major depressive disorder not to let problems or negative thoughts overwhelm them.

"Scientists have known for a while that both of these activities alone can help with depression," says Shors. "But this study suggests that when done together, there is a striking improvement in depressive symptoms along with increases in synchronized brain activity."

Rutgers researchers say those who participated in the study began with 30 minutes of focused attention meditation followed by 30 minutes of aerobic exercise. They were told that if their thoughts drifted to the past or the future they should refocus on their breathing - enabling those with depression to accept moment-to-moment changes in attention.

Shors, who studies the production of new brain cells in the hippocampus - the portion of the brain known to be necessary for some types of new learning--says even though neurogenesis cannot be monitored in humans, scientists have shown in animal models that aerobic exercise increases the number of new neurons and effortful learning keeps a significant number of those cells alive.

The idea for the human intervention came from her laboratory studies, she says, with the main goal of helping individuals acquire new skills so that they can learn to recover from stressful life events. By learning to focus their attention and exercise, people who are fighting depression can acquire new cognitive skills that can help them process information and reduce the overwhelming recollection of memories from the past, Shors says.
