Structural differences in the brain may explain why siblings differ in risk of developing conduct disorder

Structural differences in the area of the brain responsible for decision making could explain why two siblings living in the same family might differ in their risk of developing the condition conduct disorder. Psychologists and neuroscientists have long puzzled over why siblings with seemingly the same upbringing and genetic makeup might differ so significantly in […]

Study identifies nearly 600 genetic loci associated with anti-social behavior, alcohol use, opioid addiction and more

An analysis of data from 1.5 million people has identified 579 locations in the genome associated with a predisposition to different behaviors and disorders related to self-regulation, including addiction and child behavioral problems. With these findings, researchers have constructed a genetic risk score—a number reflecting a person’s overall genetic propensity based on how many risk […]

Ethnic diversity in genetic study of glycemic traits yields better results

By including multi-ethnic participants, a largescale genetic study has identified more regions of the genome linked to type 2 diabetes-related traits than if the research had been conducted in Europeans alone. The international MAGIC collaboration, made up of more than 400 global academics, conducted a genome-wide association meta-analysis led by the University of Exeter. Now […]

Scientists identify molecular mechanism behind weight gain in patients taking antipsychotics

Scientists with UT Southwestern's Peter O'Donnell Jr. Brain Institute have identified the molecular mechanism that can cause weight gain for those using a common antipsychotic medication. The findings, published in the Journal of Experimental Medicine, suggest new ways to counteract the weight gain, including a drug recently approved to treat genetic obesity, according to the […]
