One neuroscience expert claims Kiwi kids who spend too much time on their devices have developed behaviours that mimic ADHD. 

This comes as teachers are forced to adapt their teaching methods as children display behavioural issues as a result of excess screentime.

Educational psychologist and neuroscience trainer Kathryn Berkett says these kids are unable to concentrate or sit still - which are behaviours experts use to diagnose ADHD.

"We're never letting our kids spend time without external stimulation into their brains."
