Parent’s Depression May Impact Teens’ Risk-Taking Via Brain Changes

New research suggests that parental depression influences greater brain activity in areas linked to risk-taking in adolescents.

The enhanced brain activity is likely to lead to more risk-taking and rule-breaking behaviors.

While previous research has found associations between clinically depressed parents and their teenagers’ risk-taking, the new study is the first to find corresponding changes in the adolescents’ brains.

“This is the first empirical evidence to show that parental depression influences children’s behavior through the change in the adolescent’s brain,” said University of Illinois (UI) graduate student Yang Qu, who led the study with UI psychology professor Dr. Eva Telzer.

The study appears in the journal Social Cognitive and Affective Neuroscience.

“There are a lot of changes happening in the teen years, especially when we are thinking about risk-taking behaviors,” Telzer said.

For the study, researchers followed a group of 23 adolescents, 15 to 17 years old, with cognitive testing and brain imaging at the beginning and end of the 18-month study.

Investigators used functional magnetic resonance imaging to measure changes in blood oxygen levels in the brain while the study subjects clicked a button to inflate a computerized balloon.

The goal was to inflate the balloon as much as possible without popping it. More clicks earned the teens a greater monetary reward, but if it popped, they earned nothing.

“The more risky they are in real life, the more risky they are on the task as well,” Telzer said.

The researchers also collected information on the adolescents’ rule-breaking behaviors, such as sneaking out without parental permission, substance abuse, and partying.

Parental depression was measured by collecting data from parents on their own depressive symptoms. Parents were asked to respond to statements such as “I couldn’t shake off the blues” and “Everything I did was an effort.”

Telzer and Qu measured these symptoms in parents who were not currently being treated for clinical depression.

The researchers found that adolescents whose parents had greater depressive symptoms increased their risk-taking over the course of the study. The investigative team also saw changes in how the teens’ brains responded to risk-taking.

“At the neural level, they show increases over time in activation in the ventral striatum,” Telzer said. “The ventral striatum is a key brain region involved in risk-taking, and it has also been linked in some studies to depression.”

These new findings help to explain the relationship between parental depression and an adolescent’s risky behaviors, Qu said.

“Even if you are not clinically depressed and seeking out help, your teen is probably picking up on the negative emotions that you may be experiencing,” Telzer said.

This unconscious awareness can influence teens’ risk-taking behaviors and also shape the way their brains respond to risky situations.
