Understanding Childhood and Youth

It's one topic at a time. You can read it or click Listen: the phrase that sounds is color-coded.

Who this guide is for
This guide is for mothers, fathers and carers of children and adolescents. It explains what signs to watch for and how to accompany at home. It is not for diagnosis. If you are concerned about something, consult your pediatrician or a child and adolescent psychologist.
What is expected and what is not
Fears, tantrums, and mood swings are part of growing up. Adolescence brings many physical, emotional, and social changes. He worries when the discomfort lasts for weeks and doesn't subside. When it's too intense for his age. And when it interferes, he doesn't want to go to school, he leaves his friends, his performance drops dramatically.

What the data say
Worldwide, 1 in 7 teenagers aged 10 to 19 has a mental disorder. Anxiety is the most common problem at this age. It affects about 4% of 10 to 14-year-olds and just over 5% of 15 to 19-year-olds. Depression affects about 1 percent of younger people and more than 3 percent of older people. Detecting it early and treating it changes the prognosis.

Warning signs
Sudden mood swings, irritability, or sadness that don't go away. He isolates himself and stops seeing his friends. He sleeps or eats very differently than usual. He's either going down or he's refusing to go to class. He often complains of abdominal or headache without medical cause. Doing risky things or using alcohol or other substances. He hurts himself or talks about not wanting to live.

In young children
Young children express discomfort with their body and behavior. They can go back to old habits, like peeing or not wanting to sleep alone. More tantrums, fears, or excessive attachment appear. They can't always tell what's wrong with them. You have to watch what they do.
Which treatments work
Psychological treatment is the first choice in children and adolescents. It usually involves family work. Antidepressants should not be used to treat depression in children. In adolescents they are not the first choice and are used with special caution. Any medication is prescribed by a specialist doctor. Protecting against adversity and promoting emotional learning is part of prevention.

If they talk about hurting themselves
Always take it seriously. Listen calmly, without arguing or belittling. Asking directly doesn't give you the idea. Get professional help the same day. In Spain, the 024 line supports people with suicidal thoughts and their families. In an emergency, call 112.

Common myths
It's just a matter of age. Sometimes it is. If it lasts and limits you, you have to look at it. He does it to get attention. If he needs it, something happens to him. He'll get over it. Detecting it early changes the prognosis. Taking him to the psychologist will mark him. It teaches him that asking for help is normal. It's the parents' fault. Many factors play a role. Family is part of the solution.
