Personal Contemplation Triggers Increased Brain Activity during Depressive Episodes

Peter Kinderman, head of the University’s Institute of Psychology, Health, and Society, said, “We found that participants who were experiencing depressed mood chose significantly fewer positive words and more negative and neutral words to describe themselves, in comparison to participants who were not depressed. That’s not too surprising, but the brain scans also revealed significantly greater blood oxygen levels in the medial superior frontal cortex when the depressed participants were making judgments about themselves. This research leads the way for further studies into the psychological and neural processes that accompany depressed mood. Understanding more about how people evaluate themselves when they are depressed, and how neural processes are involved could lead to improved understanding and care.”

Dr. May Sarsam, from the Mersey Care NHS (National Health Service) Trust (UK), said, “This study explored the difference in medical and psychological theories of depression. It showed that brain activity only differed when depressed people thought about themselves, not when they thought about the Queen or when they made other types of judgments, which fits very well with the current psychological theory. Thought and neurochemistry should be considered as equally important in our understanding of mental health difficulties such as depression.”

The study’s findings were published October 30, 2013, in the journal PLoS ONE.
