The Lancet December 2025:Neurobehavioural links from infant screen time to anxiety

This research explores how early exposure to digital media impacts the long-term mental health of children by tracing a specific neurodevelopmental pathway from infancy to adolescence. By monitoring brain growth over several years, scientists discovered that excessive screen time during the first two years of life leads to an accelerated maturation of brain networks responsible for vision and cognitive control. This premature structural change eventually manifests as impaired decision-making speeds, which serves as a critical bridge to increased anxiety symptoms by age thirteen. Ultimately, the study reveals that the sensory overstimulation provided by screens may disrupt healthy brain integration, offering a new biological explanation for why limiting early childhood screen use is vital for emotional stability later in life.
