Adolescent mental health

Adolescence is a time of extraordinary and life-changing transformation. The brain is profoundly reconfigured, identity is sought, emotions are amplified, relationships with parents and peers are reorganized. These transformations are normal and necessary. But they also create particular vulnerability: according to the WHO, mental disorders represent 16% of the burden of morbidity and disability among 10-19 year olds. And according to a Public Health France survey (2022), 24% of high school students present significant depressive symptoms. Adolescence is a key period for prevention, and the adults who surround young people play a determining role. Here's how to recognize the signals and how to create the conditions for possible dialogue.

1. What happens in the adolescent brain

Adolescence is a period of intense neurodevelopment. The brain undergoes a profound remodeling which explains many of the behaviors characteristic of this period:

• ●The prefrontal cortex: the area of the brain responsible for reasoning, emotional regulation and anticipation of consequences does not finish developing until around 25 years old. This is why adolescents are more impulsive, more sensitive to emotions and more inclined to take risks, it's not bad will, it's neurobiology.

• ●The limbic system: the center of emotions and reward is in full swing during adolescence. Emotional intensity, sensitivity to the gaze of peers, the search for novelty and sensations are normal manifestations of this activation.

• ●Neuroplasticity: the adolescent brain is extraordinarily plastic, capable of very rapid learning but also very vulnerable to environmental factors (stress, substances, trauma). It’s an opportunity and a risk simultaneously.

  Signal	Which is normal	What deserves attention
  Mood	Mood swings, temporary irritability, need for space	Sadness or irritability persists for more than 2 weeks, frequent crying for no reason
  Sleep	Sleep-wake shift, going to bed late	Chronic insomnia or hypersomnia, exhaustion despite getting enough sleep
  Social relationships	Peer group investment, distance from parents	Total withdrawal, breakdown of friendships, lasting isolation
  Behaviors	Moderate risk-taking, experimentation	Dangerous driving, risky drinking (alcohol, cannabis), self-harm
  School	Temporary drop in motivation, extracurricular concerns	School dropping out, absenteeism, sudden drop in results
  Food	Increased attention to body image	Severe restriction, purgative behaviors, obsession with weight

2. Warning signs that should not be trivialized

Adolescence involves mood changes, a search for autonomy, conflicts with adults, it's normal. Here's what's not:

3. The most common disorders in adolescence

Depression: affects around 8% of adolescents. It often manifests itself through irritability rather than sadness, social withdrawal, loss of interest in usual activities, sleep problems and self-devaluation.

Anxiety disorders: the most common at this age. Social anxiety (fear of peer gaze and judgment), academic performance anxiety, panic attacks. Can lead to avoidance and dropping out of school if left untreated.

Eating disorders: peak prevalence in adolescence, particularly among girls. Anorexia, bulimia and binge eating should be detected early; the prognosis is better when treatment is rapid.Self-harm: affects 10 to 20% of adolescents according to studies. Often an attempt to regulate unbearable emotional pain, not necessarily suicidal intent, but a signal of serious distress that requires urgent professional help.

4. How to create the conditions for dialogue

Don't wait until things are bad to speak. Regular conversations about emotions, relationships and well-being, outside of crises, create a space of trust that the adolescent can come to when they are really hurting.

Listen without immediately resolving. Adolescents often need to be heard before being advised. Resisting the impulse to provide solutions creates a space in which they can move on from what they are experiencing.

Do not trivialize or dramatize. Avoid both “it’s nothing, everyone goes through that” (which closes the dialogue) and “it’s terrible, you scare me” (which overloads the adolescent with guilt). The right posture: “I hear you, it seems difficult, I’m here”.

Maintain the connection even in conflict. Teenagers need separation, and need to know that the bond remains strong despite the conflict. Setting clear limits while maintaining a caring presence is the most protective parental posture.

Refer to professionals without stigmatizing. Offer professional help as a normal resource, not as a punishment or a sign of failure. “There are people whose job it is to help when things are difficult, and it would be a shame not to take advantage of it. »

5. Resources for teenagers and their parents

In case of distress, several resources are directly accessible to adolescents:

• ●3114: National Suicide Prevention Number, accessible 24 hours a day, free, confidential, for adolescents in crisis and for worried parents.

• ●3020: national number against school bullying.

• ●The CMP (Medico-Psychological Center): accessible without appointment, free, with psychologists and psychiatrists specializing in adolescence.

• ●My treating doctor: first point of entry, can refer you to a child psychiatrist or a specialized psychologist.

In the event of self-harm or suicidal thoughts, do not leave the adolescent alone and immediately contact 3114 or 15 (SAMU).
