Your teenager NEEDS YOU to listen to this podcast ... Hayden chats with David Gillespie, author of the book - Teen brain. Learn how the teen brain actually works, the dangers of addictions and in particular addiction to screens and the problems caused by addiction including anxiety, depression and possible self harm among other things. The world is continually evolving but the chemicals of the brain will always be the same. We owe it to our children or any young adults we care for to learn more to help us strap in for the ride that comes with a developing brain.
