Bipolar in children

Big feelings are part of childhood. When moods swing much further than that, a careful look, without labels or blame, is the kindest first step.

By the numbers

Bipolar in young people, from trusted sources.

Experts still debate how often bipolar starts in childhood. These numbers show that it is uncommon in young children, more common in teens, and that careful assessment matters. Studies count in different ways, so numbers vary.

How common

Close to 0was the rate of bipolar-type conditions before the teen years in several newer community surveys (review of surveys, 2021).
1.8%of young people had a bipolar-type condition in an earlier pooled estimate of 12 community surveys, which experts still debate (review, 2021).
2.9%of U.S. teens aged 13–18 have had bipolar at some point (NIMH, survey 2001–2004).
3.3 millionadolescents aged 10–19 worldwide experienced bipolar in 2023 (WHO).

Diagnosis

25 → 1,003U.S. doctor visits per 100,000 young people included a bipolar diagnosis in 1994–95 vs 2002–03, a rapid rise that led experts to call for more careful diagnosis (2007).
32%of those youth visits also included an ADHD diagnosis, showing how much the two can overlap (2007).
2013is when a separate childhood mood condition, DMDD, was added to diagnostic manuals for children with ongoing irritability and frequent outbursts (NIMH).

Family history

10.6% vs 0.8%of school-aged children of a parent with bipolar vs other children had a bipolar-type condition in one U.S. study (2009).
40%lower risk of children developing a mental health condition when families with a parent’s mental illness took part in prevention programs (review, 2012).

Can young children have bipolar?

It can happen, but it’s uncommon, and experts take great care.

Most of the time, bipolar starts in the late teens or early adult years. NIMH notes that, occasionally, children can have symptoms too.

In the 1990s and early 2000s, U.S. diagnoses of bipolar in young people rose very quickly. Many experts worried that some children were being labelled too fast, and called for more careful assessment.

⚖️ Why getting it right mattersMissing it and over-labelling can both cause harm.
Read more

Spotting bipolar early matters, but so does avoiding a label that doesn’t fit. Experts say both under- and over-diagnosis are real concerns.

Diagnosis needs a careful, thorough evaluation by a trained, experienced mental health professional.

🎓 Teens are differentBipolar becomes more common in the teen years.
Read more

Rates are much higher in teens than in younger children. If your child is 13 or older, the teens guide will fit better.

See Bipolar in teens & young adults.
Whatever is going on, your child is still your child: curious, funny, loving and growing. A diagnosis, if one comes, is one part of their story, not the whole thing.

Big feelings, or something more?

What sets mood episodes apart from everyday ups and downs.

All children have tantrums, silly moods and sad days. With bipolar, the changes in mood, energy and sleep are more extreme, often come without a clear reason, and last for days or weeks, for most of the day.

⚡ An “up” periodMuch more energy than usual, with little need for sleep.
Read more

Children with bipolar sometimes feel very happy or “up” and are much more energetic and active than usual. They may have trouble sleeping but not feel tired.

It can also look like a very short temper, racing thoughts or risky behaviour.

🌧️ A “down” periodMuch less active, sad, and often with body aches.
Read more

Children may feel very sad or “down” and be much less active than usual. Some complain a lot about stomachaches or headaches.

Some children have thoughts of death. This always needs prompt help.

If a child talks about wanting to die, call or text 988 (U.S.) now. If a life is in danger, call 911.
🔁 Episodes, not constantA clear change from how your child usually is.
Read more

With bipolar, mood comes in episodes that are a clear change from the child’s usual self. That is different from a child who is irritable or angry most of the time.

This is not a checklist for diagnosing your child. It’s a guide to what is worth writing down and talking about with a professional.

Other things that can look similar

Why a careful look at the whole child matters.

Signs of bipolar can overlap with other conditions that are common in young people. That’s one reason professionals take time before giving any diagnosis.

🏃 ADHDRestless, distractible and impulsive, most of the time.
Read more

NIMH lists ADHD as one of the conditions that can overlap with bipolar in children. In one U.S. study, about a third of youth visits with a bipolar diagnosis also listed ADHD.

ADHD signs are usually steady over time, while bipolar comes in episodes. Some children have both.

😤 DMDDOngoing irritability and frequent, intense outbursts.
Read more

Disruptive mood dysregulation disorder (DMDD) is a childhood mood condition with ongoing irritability, anger and frequent, intense temper outbursts. It was added to diagnostic manuals in 2013.

Children with DMDD are diagnosed between ages 6 and 10, after symptoms have lasted 12 months or more.

😟 Anxiety and depressionWorry or low mood can bring irritability and poor sleep.

It can be hard to tell bipolar apart from depression without highs. Anxiety and other mood difficulties are also common in children.

🌙 Stress, trauma and poor sleepLife events can change behaviour a lot.
Read more

Big changes, frightening experiences or ongoing poor sleep can all affect a child’s mood and behaviour. A good assessment asks about what’s been happening in the child’s life.

See Trauma: what it is & how it affects you and Sleep & mental health.

When bipolar runs in the family

A reason to watch kindly, not to worry constantly.

Having a parent or sibling with bipolar raises a child’s chance of developing it. But not everyone with a family history will.

🔢 What one study foundAbout 9 in 10 children of a parent with bipolar did not have it.
Read more

In a U.S. study, about 1 in 10 school-aged children who had a parent with bipolar had a bipolar-type condition, compared with fewer than 1 in 100 other children.

In that study, most children who did develop it had their first mood episode before age 12, which is why family history is worth sharing with your child’s doctor.

🩺 Tell your pediatricianFamily history helps professionals see the full picture.
Read more

Professionals look at symptoms over time and at family history when assessing bipolar. Let your child’s doctor know about relatives with bipolar or other mood conditions.

🌱 Family support helpsPrograms for families can lower children’s risk.
Read more

Programs supporting families where a parent has a mental illness lowered children’s risk of developing a mental health condition by about 40%.

Family-focused therapy has also been studied with young people at high risk of bipolar.

Getting a careful assessment

Where to start, what to bring, and what to expect.

There are no blood tests or brain scans that can diagnose bipolar. Diagnosis needs a careful evaluation by a trained, experienced mental health professional, often watching patterns over time.

Steps you can take

  1. Start with your pediatrician or family doctor, who can check for other causes
  2. Ask for a referral to a child and adolescent psychiatrist or psychologist
  3. Bring a few weeks of notes on sleep, energy, mood and what sets things off
  4. Share family history and anything big happening in your child’s life
  5. Ask what else could explain what you’re seeing
  6. If you’re unsure, it’s OK to ask for a second opinion
📓 Your notes are powerfulPatterns over time are what professionals need.
Read more

Because assessment looks at patterns over time, your notes about sleep, energy and mood can help a lot.

Use the “What I’m noticing in my child” worksheet.
⏳ It can take timeA clear picture may need several visits.
Read more

Because signs overlap with other conditions, a professional may want to see how things change before giving a diagnosis. That can feel slow, but it helps get it right.

🤝 You’re part of the teamCare works best when everyone works together.
Read more

NIMH says treatment is more effective when health care providers, caregivers and young people work together. Support often includes family education and therapy, such as family-focused therapy.

For anything medical, talk with your child’s clinical provider.

Support at school

Helping your child keep learning and keep friends.

Mood symptoms can make it hard to do well in school or get along with friends. With the right support, children can keep learning, even through hard patches.

📝 504 plans and IEPs (U.S.)Formal support for children whose health affects learning.
Read more

In U.S. public schools, a 504 plan provides accommodations for students with a condition that substantially limits a major life activity, like concentrating or sleeping. An IEP provides special education services.

Examples of support

  • A calm place to take a break
  • Extra time on tests
  • Shorter assignments during hard patches
IEPs & 504 plans explains the process step by step.
🏫 Working with teachersShare what helps, at a level you’re comfortable with.
Read more

You decide how much to share. Many families find it helps to tell one key person, like the teacher, counselor or nurse, what early signs look like and who to call.

DBSA has resources for parents on working with educators.

🧑‍🤝‍🧑 FriendshipsProtecting your child’s social life.

Hard patches can strain friendships. Small, low-pressure play dates and activities your child enjoys can help keep friendships going.

A calmer home, for the whole family

Routines, sleep, calm talk, and attention for siblings.

What parents and carers can do

  • Be patient
  • Encourage your child to talk, and listen carefully
  • Help your child have fun
  • Look after yourself too
  • Understand triggers and learn ways to manage big emotions and irritability
  • Watch for major mood changes and note them for the care team
🛏️ Steady sleep and routinesPredictable days help moods stay steadier.
Read more

Regular bedtimes, wake times and meals give children a sense of safety. Trouble sleeping without feeling tired can be an early sign worth noting.

Family time & routines has more ideas.
🗣️ Calm talkDescribe what you see, not who they are.
Read more

Family-focused therapy teaches calmer communication and problem-solving, which can help the whole household.

Try “You seem really wound up tonight. Let’s slow down together,” rather than “What’s wrong with you?”

👫 Brothers and sistersSiblings need attention and information too.
Read more

Siblings may feel worried, confused or left out. A simple, honest explanation and some one-to-one time help them feel included.

Talking with your child, without stigma

Helping your child understand, and feel proud of who they are.

Children pick up how adults talk about mental health. Calm, simple words help them see their feelings as something to understand, not something to be ashamed of.

Ideas that help

  • Name feelings together: “Your body seems really busy today”
  • Praise effort and coping, not only good behaviour
  • Remind them that lots of kids need help with feelings
  • Use words like “health condition” rather than labels
  • Keep reminding them they are loved, always
DBSA’s Mood Crew program helps adults start conversations about feelings with children aged 4 to 10. Stigma & talking about mental health has more ideas.

Caring for yourself as a parent

You can’t pour from an empty cup.

NIMH says it is important that caregivers take care of themselves too. DBSA notes that parents of a child with a mood condition often feel helpless, guilty, exhausted or scared, and that these feelings are common.
