'How Teens Tick' What's Happening in a Teenager's Brain? Massive developmental changes are taking place in teenagers' brains as they rewire for adulthood. This process is so amazing that it can last from the age of about ten until the late twenties. There are some important ways that we can support young people during this stage of development, and we can also be more helpful, understanding and emphatic when we know what is happening inside their head. Discover how to help them build trust, assess risk, and make good choices. Karen Holford, a family therapist who has also studied leadership and psychology, currently works as a Family Ministries director at the Trans European Division. This webinar is part of the Youth Alive series.
