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
Diagnosis
Family history
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.

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.

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

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.

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.

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.
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.

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.

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.

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

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.
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.
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.

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.

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
- Start with your pediatrician or family doctor, who can check for other causes
- Ask for a referral to a child and adolescent psychiatrist or psychologist
- Bring a few weeks of notes on sleep, energy, mood and what sets things off
- Share family history and anything big happening in your child’s life
- Ask what else could explain what you’re seeing
- If you’re unsure, it’s OK to ask for a second opinion

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

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.

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.

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

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.

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

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-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?”

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
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.

DBSA runs free weekly, 90-minute online support groups for parents and caregivers, including a group for parents of children 17 and under.
