Are smartphones damaging kids' brains? The link to cognitive decline, early dementia

SYDNEY: With concerns over smartphone use by children growing, experts are warning about its effects on developing brains. Studies reveal a troubling correlation between prolonged screen time and issues like diminished attention, memory problems, and even structural brain changes. Professor Mark Williams from Macquarie University stresses that screen addiction may be setting young minds on a path toward early cognitive decline. Some researchers are urging policymakers to fund deeper studies to better understand these impacts and explore safeguards.
Prolonged exposure to smartphones may also disrupt children's ability to process information effectively, affecting skills crucial for learning and social interaction. The addictive design of many apps triggers dopamine release, a “feel-good” chemical, conditioning young minds to crave more screen time. Experts fear this could stifle patience, reduce impulse control, and lead to dependency, with long-term consequences for mental health. Parents are encouraged to set firm screen limits, ensuring children engage in varied, real-world activities that support healthier cognitive development and social well-being.
