“I’ve become a different kid!” What’s going on in the teenage brain?
When a child slams the door, throws a tantrum and refuses to listen, or pretends not to hear what the parent says, parents start to get nervous.
It seems like the 'puberty' we've only heard about has begun, but parents of teenagers are worried about whether they should be strict with their children to prevent them from getting distracted during this important academic period, or if they should just leave them alone and not bother them.

According to brain science, surprisingly, the 'weird' behaviors of teenagers are evidence that the child is developing well.
Adolescence is a time when cognitive and emotional abilities are at their peak.
Just as babies between the ages of 0 and 3 develop at an incredible rate to walk, crawl, run, speak, and communicate in complete sentences, the teenage brain also develops at an incredible rate to develop cognition, emotions, and social skills.
Because the range of development is so wide, the inner confusion and feelings that they experience for the first time are expressed as negative emotions, feelings, and behavioral responses, which can appear as symptoms similar to 'middle school syndrome'.
So, while the teenage brain may seem unstable, it is a time of tremendous opportunity for the brain to mature.


Knowing what's going on in your child's head gives you more room to accept their behavior.
Just as no parent would scold a baby who falls while learning to walk, we must be prepared to accept the 'strange brain' of our children who are developing 'humanly' and 'adultly'.

"Why is my child so weird?" You need to understand your child's unique "code."
In addition to understanding the brain development of teenagers, there are some important keywords to keep in mind.
It is ‘my child’s unique uniqueness.’


Professor Kim Boong-nyeon, a renowned pediatric and adolescent psychiatrist, advises parents of teenage children to do two things when meeting them.
The first is to understand the characteristics of teenage brain development so you can be more accepting of your child. The second is to think back to your child's infancy and early childhood.
Why should we recall our childhood when our children are teenagers?

Every child in the world is different.
Each child has a unique temperament, and there are also aspects that develop as the child adapts to the environment.
My child's unique 'code' discovered at this time is later hidden as sociality develops and is revealed like a true face during adolescence.
By discovering your child's uniqueness as guided by the author, parents can observe their child more closely and objectively reflect on how to raise them.
This book will help you understand what that code is, what hints there are for dealing with your child during puberty, and how to transition your role as a parent.

For the brains of teenagers standing on the borderline between 'development' and 'pain'
Teenagers cross boundaries.
Even children who had no problems before can become very shaken by strange behavior, excessive immersion, game addiction, anger toward parents, and self-loathing.
Most teenagers will eventually regain their balance after exhibiting these behaviors, but in some cases, the behaviors can become so severe that, without proper intervention, they can lead to serious mental health problems.

In fact, the incidence of mental health problems in teenagers is higher than you might think.
Schizophrenia, which was mainly known as an adult mental health problem, is said to have an approximately 40% chance of developing in mid-adolescence, that is, in the mid-teens.
Although the illness began in adolescence, many people miss the appropriate treatment period and only receive treatment for schizophrenia in adulthood.
The same goes for bipolar disorder.
More than 50% of bipolar patients treated in adulthood report that their initial bipolar symptoms began in their teens.


Because the line between temporary anomalies and illness is blurred in the behavior of teenagers, it's important to observe them more closely and gather information from multiple perspectives.
And we must use assessment methods that are appropriate for the age and developmental level.
This is why there is a separate department of psychiatry that deals with children and adolescents.

Professor Kim Boong-nyeon, a specialist in child and adolescent psychiatry at Seoul National University Children's Hospital, has been conducting mental health research integrating brain and psychological development in infants, children, and adolescents for over 20 years.
The author says he feels great sorrow when he meets children whose mental health issues are not addressed early and only come to him when they are severely advanced.
Just as anyone with a weakened immune system can catch a cold, anyone can develop a sick brain.
Therefore, the teenage years are a time when the role of parents is more important than ever, requiring close observation and timely intervention.

This book will be a useful tool for parents who are struggling to raise their teenage children.
