Multiple substance use disorders may share inherited genetic signature

A new study suggests that a common genetic signature may increase a person’s risk of developing substance use disorders, regardless of whether the addiction is to alcohol, tobacco, cannabis or opioids. The research, led by Washington University School of Medicine in St. Louis, eventually could lead to universal therapies to treat multiple substance use disorders […]

Problems persist for kids exposed to cannabis in the womb

Children who were exposed to cannabis in the womb continue to show elevated rates of symptoms of psychopathology — depression, anxiety and other psychiatric conditions — even as, at ages 11 and 12, they head toward adolescence, according to research from the Department of Psychological & Brain Sciences’ BRAIN Lab, led by Ryan Bogdan, PhD, associate […]

SSRI use during pregnancy not related to childhood depression

In one of the first studies to look at the association between selective serotonin reuptake inhibitors (SSRI) medications and brain development in young children, research from the Behavioral Research and Imaging Neurogenetics (BRAIN)Lab at Washington University in St. Louis found no association between children’s exposure to the drugs in the womb and later childhood depression.  The study […]

Ryan Bogdan, PhD, ​associate professor of psychological and brain sciences in Arts & Sciences at Washington University in St. Louis, has been selected as a 2022 American Psychological Association (APA) Fellow. In his research, Bogdan investigates genomic and environmental factors associated with the risks of psychopathology, as well as their biological correlates. To be named […]

Prenatal, early-life influences on child brain development focus of new study

Researchers at Washington University School of Medicine in St. Louis are joining scientists at 24 other sites around the country to conduct a comprehensive study aimed at understanding how prenatal factors and early life experiences influence brain development and behavior in infants and young children. With more than $37 million in funding from several institutes […]

Cannabis use disorder: another COVID risk factor

Should doctors take particular care to talk to patients about the potential dangers of COVID-19 if those patients have a problematic relationship with pot? New research from Washington University in St. Louis suggests perhaps they should. Diabetes, obesity and a history of smoking cigarettes are all considered risk factors for poorer COVID-19 outcomes. Warnings and […]

Prenatal cannabis exposure associated with adverse outcomes during middle childhood

While cannabis use during pregnancy is on the rise, researchers at Washington University in St. Louis have found evidence that the resulting children are more likely to have psychopathology in middle childhood. The team’s analysis are the first steps in studying the effects of cannabis on children as attitudes surrounding its use change rapidly — […]

Which came first: brain size or drinking propensity?

For years, researchers have observed that alcohol consumption is associated with reduced brain volume and concluded that drinking can literally shrink the brain. But new research turns that theory on its head, suggesting that reduced brain volume may represent a genetically-conferred predispositional risk factor for heavier alcohol consumption. “Our results suggest that associations between alcohol […]

Bogdan awarded $265K from NIH

Ryan Bogdan, associate professor of psychological and brain sciences in Arts & Sciences, received a two-year, $264,938 grant from the National Institutes of Health (NIH) to study the effects of alcohol on the maturing brain. The study will look at genome-wide association studies to longitudinal neuroimaging studies of adolescents and young adults in order to […]

Researchers receive $3 million to study how adversity affects offspring’s health

Washington University in St. Louis psychology researchers Ryan Bogdan and Thomas Oltmanns received a federal grant totaling more than $3 million to study how adversity may perpetuate racial health disparities and health outcomes within families. The National Institutes of Health (NIH)’s National Institute on Aging is providing the funding, spread over five years. Despite growing evidence […]

Cannabis during pregnancy bumps psychosis risk in offspring

Pregnant women who use cannabis may slightly increase the risk their unborn child will develop psychosis later in life, suggests new research from Washington University in St. Louis. Fine “Our research shows that prenatal marijuana exposure after maternal knowledge of pregnancy is associated with a small increase in psychosis proneness during middle childhood or about […]
