Hormone May Explain Cognitive Decline in Adults Who Experienced Childhood Abuse

Feb 14 2019
Many people who experienced abuse as children also experience cognitive decline as adults. A new study has shown that the hormone interleukin-6 (IL-6) is commonly found in very high levels in these individuals. IL-6, which is involved in processes of swelling and inflammation, can be controlled with medication. Understanding the role of IL-6 may be an important new step to improve the lives of people who experience childhood abuse. For more information about this study, please visit the NIH website.

People with treatment-resistant depression had microbiomes that were less likely to contain serotonin- and dopamine-creating bacteria. Although more investigation is needed, this is a fascinating direction for future research. For more information on this study, please see this article in Forbes.

Brain Biomarkers, Structural Differences May Predict Severity of PTSD

Jan 30 2019
A new study examining the brain structure and activity of combat veterans with PTSD may help explain why some people experience symptoms of PTSD much more severely than others. Certain areas of the brain involved in learning and emotional response, most noticeably the amygdala, were meaningfully different in veterans with more severe symptoms. For more information about this study, please visit the NIH website.
