Studies show early and prolonged exposure to screens may be associated with higher autism spectrum disorder symptoms in children

New Delhi, May 1, 2026 — Excessive screen time during early childhood could be linked to a higher risk of autism spectrum disorder (ASD), a leading expert from the All India Institute of Medical Sciences (AIIMS), New Delhi, has cautioned, citing emerging research and global guidelines.

Dr. Shefali Gulati, Professor in the Department of Paediatrics at AIIMS New Delhi, said multiple studies and meta-analyses indicate a strong correlation between early exposure to screens and increased prevalence of autism-related symptoms in young children.

“Research and several studies have shown that children who had higher screen time at a younger age were more likely to show autism spectrum symptoms by the age of three. Meta-analyses suggest that the earlier the exposure and the longer the duration of screen time, the stronger the correlation with autism,” Dr. Gulati said, while speaking to the media.

Autism spectrum disorder is a neurodevelopmental condition that affects communication, behaviour, and social interaction. While its exact causes remain complex and multifactorial, experts are increasingly examining environmental and behavioural factors, including digital exposure in early childhood.

Dr. Gulati pointed out that hospital-based observations also support these findings. “When we compared children diagnosed with autism to other children, we observed that screen exposure had started earlier in those with autism and the duration was significantly higher. Their screen dependency or addiction scores were also higher,” she noted.

She emphasised that while screen time alone may not directly cause autism, excessive exposure during critical developmental stages could aggravate or be associated with developmental concerns.

Highlighting the importance of early intervention, Dr. Gulati stressed the need to regulate children’s exposure to digital devices. “It is very important to reduce screen time. We have clear guidelines from global and national bodies,” she said.

According to recommendations by the American Academy of Paediatrics, the Indian Academy of Paediatrics, and government advisories, children below 18 months should not be exposed to screens at all. For children between 18 months and six years, screen time should be limited to no more than one hour per day, and even that should be passive and supervised.

“Many countries are now moving towards stricter controls. Some have even banned screen exposure for very young children. The focus should be on increasing human interaction rather than digital engagement,” Dr. Gulati added.

Experts underline that early childhood is a critical period for brain development, especially for language acquisition and social skills. Excessive reliance on screens, particularly passive consumption through apps or videos, may limit real-world interactions that are essential for cognitive and emotional growth.

“Technology use in itself is not the issue, but the nature of engagement matters. Passive screen use cannot replace human interaction, which is crucial for language development and social communication,” Dr. Gulati explained.

She urged parents to prioritise direct engagement with children through conversation, play, and other interactive activities. “The more we interact with children individually, the better it is for their development. That human connection is irreplaceable,” she said.

With digital devices becoming increasingly ubiquitous, concerns about their impact on children’s health are growing worldwide. Experts advise that parents and caregivers adopt mindful usage practices, ensuring that technology does not replace essential developmental experiences.

The warning comes amid rising cases of developmental disorders and increasing dependence on digital devices among young children, particularly in urban settings.

Health professionals stress that while technology can be a useful tool when used appropriately, unregulated and excessive exposure during formative years may carry long-term consequences.

As awareness grows, experts say that balancing technology use with meaningful human interaction will be key to safeguarding children’s developmental health.
