By about 11 or 12 years old, a child's brain is nearly as large as it will ever be, but its development is far from finished. From early adolescence until the mid-20s, the dramatic reshaping of connections between brain cells sculpts regions involved in planning, organization, and many other cognitive functions that we associate with "growing up." This may make teens more vulnerable to psychiatric disorders that often arise during adolescence, such as schizophrenia, but it may also present an exciting chance to shape the brain long-term. What do we know about these risks and opportunities? And how can discoveries about the teen brain inform how we parent and educate our children?
