The Screen Habits Rewiring Our Kids’ Brains [with Dr Mark Williams]

Your child’s brain is being shaped right now — and screens may be changing it faster than most parents realise.

In this confronting but deeply practical conversation, neuroscientist Professor Mark Williams joins Dr Justin Coulson to unpack what excessive screen use is actually doing to developing brains. From dopamine loops and gaming addiction to social disconnection, emotional health, and the alarming changes researchers are seeing in children’s brains, this episode explains why so many parents feel like they’re losing their kids to devices — and what they can do about it.

You’ll hear the simple question Mark asks his own son to check whether gaming is becoming a problem, why “educational apps” may not be as educational as parents think, and the small changes that make the biggest difference.

If you’ve ever wondered whether screens are really affecting your child… this episode will stay with you.
