Increasingly, evidence is suggesting that inflammation may drive some depressive symptoms, such as low mood, loss of appetite and reduced ability to sleep.
What the new study set out to investigate was whether inflammation is a driver of clinical depressionindependent of other physical illness.
The PET scans showed significant inflammation in the brains of the people with depression, and the inflammation was most severe among the participants with the most severe depression. The brains of people who were experiencing clinical depression exhibited an inflammatory increase of 30%.
