Key Brain Circuit Linked to Teen Anxiety Identified
Summary: Brain imaging in nearly 3,500 adolescents reveals that disrupted connectivity across a key subcortical-cerebellar circuit—connecting the amygdala, thalamus, and cerebellum, is directly associated with heightened anxiety. The alterations, already…
Adults With ADHD Face Higher Long-Term Dementia Risk
Summary: A massive study of more than 187,000 older adults enrolled in the NIH’s All of Us Research Program reveals that adults with attention-deficit/hyperactivity disorder (ADHD) face more than quadruple…
Daily Steps Tied to Lower Teen Depression
Summary: A longitudinal study tracking more than 5,500 American adolescents reveals that higher daily step counts directly correlate with fewer mental health issues one year later. Led by researchers at…
Inflexible Math Brain: How Neural Circuit Glitches Block Problem Solving
Summary: Stanford University researchers analyzing brain activity and behavioral metrics in 8- to 10-year-olds found that children with developmental dyscalculia struggle to switch between and optimize math problem-solving strategies. Distinct…
The Placenta May Decide Autism Vulnerability
Summary: A new study in mice reveals that maternal immune activation during a precise gestational window triggers autism-like developmental disruptions exclusively in male fetuses. Researchers traced this vulnerability to damaged…
Eye-Blink Rate Predicts Cognitive Flexibility in Preschoolers
Summary: Researchers have discovered that spontaneous eye-blink rate serves as a simple, noninvasive marker for tracking the development of executive function in early childhood. The study revealed that children aged…
Early Stress Heightens Adult Anxiety
Summary: Researchers uncovered a fundamental epigenetic mechanism explaining how early-life adversity permanently alters the brain’s stress response networks. The study identified that childhood trauma increases levels of the enzyme SETD7…
AI Models Analyze Children’s Speech to Predict Future Mental Health
Summary: Researchers demonstrated that natural language processing (NLP) models analyzing speech patterns in children aged 9 to 13 can predict the onset of mental health disorders six years later more…
Study Links Childhood Unpredictability to Mental Health
Summary: A study establishes childhood unpredictability as a distinct risk factor for youth mental health. Screening nearly 30,000 children across 19 pediatric clinics, the team found that inconsistent household routines…
