A new study by AIIMS Delhi has raised concerns about digital screen exposure in infants. Researchers found that children exposed to screens very early in life may show autism-like signs by the age of three. Experts now strongly advise avoiding screens before 18 months, and ideally keeping children screen-free until age three to support healthy brain development. Doctors clarified that screen use does not directly cause clinical autism, but it may increase the risk of what specialists call “virtual autism” developmental delays linked to excessive digital exposure. What is Autism? Autism, or Autism Spectrum Disorder (ASD), is a neurodevelopmental condition that affects how a child communicates, interacts, and behaves. It is called a “spectrum” because symptoms vary widely. Some children need extra support in daily activities, while others live independently with mild challenges. Early brain development plays a major role in how autism appears. What the AIIMS study found? The study involved 250 children aged 3–6 years, including 150 with autism and 100 with typical development. Researchers observed that children with autism had: The findings support earlier global research. A 2022 JAMA Paediatrics study of over 84,000 mother-child pairs also linked longer screen exposure at age one with higher chances of ASD by age three. Why early screen exposure matters According to Dr. Sheffali Gulati from AIIMS Delhi, early screen exposure may affect brain chemistry and behavior. Researchers suggest future studies should examine biological changes involving melatonin and dopamine, which influence sleep and attention. Autism risk is influenced by genetic and environmental factors, including pollution, parental age, lifestyle habits, and excessive digital exposure. Early intervention works best because the brain develops fastest during the first three years of life. Autism rates are increasing worldwide. The World Health Organization estimates about 1 in 100 children is affected. Experts stress that early identification and balanced digital habits can make a meaningful difference in a child’s development.
