Adolescence is a sensitive period for brain development and mental health, though the connection between the two is not fully understood. New research published in Imaging Neuroscience identifies a link between specific brain circuits and anxiety, which could become the targets of precision interventions to improve mental health outcomes in youth.

Millions of Americans use cannabis products as sleep aids, but a new Northwestern Medicine study suggests marijuana may not improve sleep the way many people believe it does.

The study reveals that small changes in the gene MECP2 on the X chromosome might help explain part of this difference.

A new randomized study found that children who participated in a community-based intervention targeting sugary drinks had greater improvements in BMI measures over 12 months compared with children in comparison sites. The intervention consisted of interactive activities, health education, and youth engagement to promote healthier beverage choices.
