What happens during adolescence

Adolescence isn't a disorder you just have to get through, but a phase of intense reorganisation. Body, brain, social roles, and self-image all change simultaneously – and not at the same pace.

Young people want to find their own way. What they can already handle well and where they still need support varies from person to person.

Brain development – a closer look.

Every young person develops at their own pace. A general model of brain development won't explain why your child is angry or shutting down right now. Ask about the specific situation.

This explains tendencies – not individual actions. Your child isn't 'run by their brain'. They make decisions through an interplay of development, experience, the situation, stress and the social context around them.

Strong emotions on their own don't explain a cause or provide a diagnosis.
Ask about workload and exhaustion before treating an argument as an attitude problem.
New ways of communicating and organising can be tried out together; a specific outcome cannot be guaranteed.

Identity and autonomy

Adolescents build their own self-image – often by differentiating themselves. Disagreement at home is often developmental work, not rejection.

In competitive sports, a risk arises: If identity is defined almost exclusively by sport, setbacks affect the whole person. Other roles – friend, student, musician, sibling – act like a safety net.

Emotions

Feelings can shift quickly. Give your teenager space to put things in their own words; ask what it felt like for them, without telling them how to see it.

You can model how to take a pause yourself and address poor tone later on.

Negotiating independence in concrete steps

Your child wants to pack their own kit bag, but forgets something. Don't make it about their overall maturity; keep it to this specific task: what are they taking on themselves, and what kind of reminder would help? One slip-up doesn't mean you have to take over organising everything again.

Distinguish between shared decision-making and safety: training goals and wanting to talk belong more and more to your child. When it comes to risk, crossing boundaries, or health concerns, adults keep the responsibility. Autonomy doesn't mean leaving them to deal with difficulties alone.

It doesn’t mean a lack of maturity, nor does it point to a single biological cause.

In short

Behaviour has multiple causes simultaneously.
Setting boundaries is developmental work, not an attack.
An identity outside of sport protects against setbacks.

These everyday reflections do not constitute a diagnosis or prove an individual cause. Specific physical or psychological symptoms should always be evaluated by a professional.
