Depression in Children and Teens: More Than a Bad Mood

Reviewer: Ayşegül Yel, Clinical Psychologist · 2026-10-31

For a while it looked like ordinary teenage moodiness. Leyla stopped going to basketball, which she had loved since she was eight. She slept until noon at weekends and lay awake until two on school nights. She snapped at her younger brother over nothing, and when her father asked what was wrong, she said "nothing" and closed her door. Her grades slipped. Her parents told each other it was a phase, and then one evening her mother saw a message on the family tablet that said, "I'm so tired of everything." Depression in young people often hides behind behavior that looks like attitude, laziness or normal adolescence. It is common, it is serious, and it responds well to treatment. This guide explains how to recognize it, how it is treated, and how to talk to your child about the hardest questions.

At a glance

What it is, and what it isn't

Everyone has sad days, and teenagers especially can swing from high to low in an afternoon. Sadness after a loss, a breakup, a falling-out or a disappointing result is a healthy response, and it usually eases as life moves on.

Depression is different in how deep it goes, how long it lasts and how much of life it touches. Under the standard diagnostic criteria, symptoms are present most of the day, nearly every day, for at least two weeks, and they get in the way of school, friendships and family life. The US National Institute of Mental Health (NIMH), in its guide for teenagers, puts it simply: "Being a teenager can be tough, but it shouldn't feel hopeless."

One feature catches many parents out. In children and teenagers, the main mood in depression may not be sadness at all, but irritability: snapping, short temper, everything being "annoying". A child who seems angry all the time may in fact be depressed. The NIMH lists signs such as:

Depression looks different for everyone; a young person might have many of these symptoms or just a few.

How it can look at different ages

Why it happens

Depression in young people usually comes from several factors together.

None of this means a parent has failed. Depression can affect children from loving, attentive families. What families can do, as we will see, is a vital part of recovery.

How it is assessed

Start with a conversation, then a doctor. If you are worried, talk with your child (see the steps below) and make an appointment with your pediatrician or family doctor. The US Preventive Services Task Force recommends routine depression screening for every adolescent aged 12 to 18, so you can also ask for it at a regular check-up.

What happens. A doctor or child mental health professional will talk with your child, usually partly on their own, and with you. They will ask about mood, sleep, appetite, energy, school, friendships, stress, alcohol and drugs, and directly and calmly about self-harm and suicidal thoughts. Questionnaires completed by your child and by you are common. A physical check may look for medical problems that can mimic depression, such as thyroid problems or anemia.

Confidentiality. Teenagers often talk more freely without a parent in the room. Clinicians will usually explain that what your teenager tells them stays private unless there is a risk to their safety. This protects your child's trust, and it is in your interest too.

Only a professional can diagnose. Recognizing your child in this article is a reason to ask for help, not a conclusion.

Treatment: what the evidence supports

NICE's guideline on depression in children and young people uses a stepped approach that matches treatment to severity.

Mild depression. If a young person's depression is mild and might lift on its own, NICE recommends a further check within two weeks ("watchful waiting") rather than rushing into treatment. If it persists, the next step is a time-limited psychological therapy for about two to three months, such as digital or group cognitive behavioral therapy (CBT), group interpersonal therapy or group supportive therapy, often available through schools or primary care. For teenagers aged 12 to 18, individual CBT or attachment-based family therapy are alternatives. NICE advises against using antidepressants as the first treatment for mild depression.

Moderate to severe depression. NICE recommends a specific psychological therapy: for teenagers, individual CBT; for children aged 5 to 11, options include family-based interpersonal therapy, family therapy, psychodynamic therapy or individual CBT.

What therapy involves. CBT helps young people notice and challenge the harsh, hopeless thoughts that depression produces, and gradually return to activities that bring a sense of pleasure and achievement, even before they feel like it. Interpersonal therapy focuses on relationships and the conflicts and changes that affect mood. Family-based approaches help the whole family communicate and support recovery.

The place of medication. For moderate to severe depression, a child and adolescent psychiatrist may recommend an antidepressant. NICE is clear that it should only be offered together with psychological therapy, never on its own, and with close monitoring, for example weekly contact with the young person and family during the first four weeks. This is because, in a small number of young people, these medicines can bring new or worse thoughts of self-harm in the early weeks, so any such change must be reported to the doctor at once. In the TADS study, combined treatment worked fastest; by 36 weeks, therapy alone and medication alone had caught up, with about 8 in 10 responding to each.

Recovery takes time. Most young people improve over weeks to months. Keep going with treatment even after the first improvements, because stopping too early is a common reason for relapse.

What helps at home

  1. Open the door, and keep it open. Choose a side-by-side moment, such as a drive or a walk. "You've seemed really down lately, and I miss you. I'm not angry. I just want to understand how things are for you." If they say "nothing", try again another day. Persistence without pressure tells them you're not going anywhere.
  2. Listen more than you fix. When they do talk, resist the urge to reassure ("You've got so much going for you") or solve. Try: "That sounds really hard. Tell me more." Feeling understood is often the first relief.
  3. Ask directly about suicide if you are worried. "Sometimes when people feel this low, they think about not wanting to be alive. Have you had thoughts like that?" A 2014 review in Psychological Medicine found that asking does not put the idea in someone's head, and that talking about it may reduce suicidal thoughts.
  4. Make the home safer. The American Academy of Pediatrics advises families of at-risk young people to restrict access to lethal means. Lock away medicines, including over-the-counter painkillers, and sharp objects; if there is a firearm in the home, remove it or store it locked and unloaded, with ammunition locked separately.
  5. Protect the foundations, gently. Encourage regular sleep and wake times, regular meals, daylight and movement, and time with people, even when your child doesn't feel like it. The NIMH notes that staying active and spending time with friends or family can help. Small, doable steps ("Come walk the dog with me for ten minutes") work better than big demands.
  6. Look after yourself and stay connected to school. Ask the school for flexibility with deadlines during treatment, and find support for yourself. Caring for a depressed child is exhausting, and your steadiness matters.

Myths and facts

"It's just teenage moodiness." Ordinary moodiness comes and goes. Depression lasts weeks, colors most of the day and gets in the way of life. When in doubt, ask a professional; the cost of checking is small.

"Asking about suicide will put the idea in their head." Research shows the opposite: asking directly and calmly does not increase suicidal thoughts and may reduce them. Many young people feel relieved when someone finally asks.

"Antidepressants are the main treatment for depressed children." For children and young people, NICE recommends psychological therapy first. Medication can help in moderate to severe depression, but only alongside therapy, with careful monitoring.

When to get help right away

Get help immediately, without waiting for an appointment, if your child:

Call your local emergency number or go to the nearest emergency department. Do not leave your child alone, and remove anything they could use to harm themselves.

In one sentence

Depression in children and teens often looks like irritability, withdrawal or a drop in grades rather than tears, it is common and treatable with talking therapy first, and one of the most protective things a parent can do is ask, listen, and ask directly about suicide when worried.
