The findings were published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

"This finding helps refine our understanding of how two types of known risk factors for depression, life events exposure and neural response to wins and losses, might interact to influence depression," said first author Katherine Luking, PhD, of Stony Brook University, New York. The link between brain response, impact of daily experiences, and depressive symptoms in the study indicates that brain function determines how life experiences contribute to risk for and protection against depressive symptoms.

Exposure - Life - Events - Risk - Depression

Exposure to negative life events in particular has been strongly linked to increased risk for depression. "This study is novel in that we go beyond negative events to investigate the unique effects of both positive and negative life events on depressive symptoms during a vulnerable time in development, early adolescence," said Dr. Luking.

Adolescent girls, 8-14 years old, performed a task in which they could win or lose money. Girls with a stronger brain response to winning showed a relationship between positive life events dependent on their behavior -- such as making a new friend -- and reduced depressive symptoms.
