Conduct disorder — often characterized by aggression, theft, vandalism, violations of rules and lying — is one of the most prevalent and debilitating psychiatric disorders that emerges during childhood and adolescence.
There is a subgroup of those with conduct disorder who are more likely to engage in chronic violence and criminal behavior. These individuals display severe behavioral and personality symptoms, called callous-unemotional traits, that include callousness toward others, lack of empathy or guilt for their harmful behaviors, and shallow or diminished emotional ...

Given current events ranging from the ongoing pandemic to giant wildfires and powerful hurricanes, it’s not surprising that many people find their emotional reserves are depleted. Statistics from the Kaiser Family Foundation show that about 4 in 10 adults in the U.S. have reported symptoms of anxiety or depressive disorder during the COVID-19 pandemic, up from 1 in 10 adults who reported these symptoms in the first half of 2019.
Such trends are concerning. They also illustrate just how different individuals’ responses to stress ... Continue Reading →
Ruth Brown, Ph.D. is an Assistant Professor of Psychiatry at the Virginia Institute for Psychiatric and Behavioral Genetics at Virginia Commonwealth University. Dr. Brown studies psychometric properties and measure development in patients with intellectual and developmental disabilities (IDD). Additionally, she has a background in measurement of treatment processes and outcomes of psychosocial treatments. She first became involved in this field while completing the clinical portion of her Ph.D. at a residential center serving people with IDD. During this time, ... Continue Reading →

Katie Bountress, Ph.D. is an assistant professor in Virginia Institute for Psychiatric and Behavioral Genetics at VCU. Her interests in molecular and behavioral genetics are expanding daily, as her primary discipline is psychology. She recalls learning in a class while a Ph.D. student at Arizona State University that there is not a lot known about the underlying risk factors for peer deviance and substance use. Thus, she taught herself this literature while writing her (successful) F31 grant ... Continue Reading →
Hinxton, (Scicasts) — A study published today (March 2) in the American Journal of Psychiatry details the discovery of three additional genetic risk markers for depression, building on the discovery of two genetic risk factors in 2015.
Researchers at Virginia Commonwealth University, the European Bioinformatics Institute (EMBL-EBI) and Wellcome Sanger Institute have found that the contribution of genetic variations to depression may differ between people who have experienced serious adversities in their life and those who haven’t. By carrying out a genome-wide ... Continue Reading →
Mental illness affects one in six U.S. adults, but scientists’ sense of the underlying biology of most psychiatric disorders remains nebulous. That’s frustrating for physicians treating the diseases, who must also make diagnoses based on symptoms that may only appear sporadically. No laboratory blood test or brain scan can yet distinguish whether someone has depression or bipolar disorder, for example.
Now, however, a large-scale analysis of postmortem brains is revealing distinctive molecular traces in people with mental illness. This week, an ... Continue Reading →
Dr. B. Todd Webb, Ph.D. is an Assistant Professor at the Virginia Institute for Psychiatric and Behavioral Genetics at Virginia Commonwealth University. His interest in behavioral genetics developed gradually over his academic career. He majored in biology at VCU but always had an interest in genetics. Over time, he became passionate about how complex systems work and later obtained his Ph.D. in human genetics. This allowed him to hone his skills while providing him opportunities to ...

Dr. Judy Silberg, Ph.D. is an Associate Professor in the Department of Human and Molecular Genetics. A fortuitous meeting with Drs. Lindon Eaves, D.Sc., Nick Martin, and Andrew Heath while working on her PhD in Clinical Psychology at Virginia Commonwealth University led to her life-long involvement in the field of behavior genetics. Her initial research interest began with the influence of genetic and environmental factors on pre- and peri-menstrual disorders using data on female ... Continue Reading →
