Key Takeaways
- OCD in children can start as young as 5 years old.
- Children may show OCD signs through repetitive behaviors or routines.
- Children with OCD often have obsessions about parents’ death.
Obsessive-compulsive disorder (OCD) doesn’t just affect adults; in fact, between 0.25% and 4% of children develop OCD. The average age of onset of childhood OCD is approximately 10 years old, although children as young as 5 can be diagnosed.
OCD in toddlers, preschoolers, and middle-school children shares similarities with adult OCD, but there are important differences as well. While it’s often misunderstood as a tendency to be very neat or particular, it’s much more than that. For preschoolers and other kids with the condition, it can lead to distressing thoughts and repetitive behaviors that affect how they feel, function, and cope.
In preschoolers, this might look like excessive handwashing, repeating behaviors until things are “just right,” or getting extremely distressed whenever a routine is disrupted. Recognizing the warning signs of OCD in preschoolers and middle-school children is the key to getting the right kind of support and treatment.
While OCD in toddlers is rare, it does happen in some cases. A small percentage of children show symptoms around age 3.
If you are concerned about your child’s behavior, knowing the signs of OCD in toddlers and children may help. Learn more about the signs, what triggers OCD in a child, and what you can do to help.
Characteristics of OCD in Toddlers and Children
OCD is a mental health condition characterized by obsessions and compulsions that interfere with daily life.
Obsessions
-
Thoughts, images, or ideas that won’t go away, are unwanted, and are extremely distressing or worrying
OCD was formerly classified as an anxiety disorder because the obsessive thoughts characteristic of the condition can lead to severe anxiety. The compulsions or rituals performed are typically an attempt to reduce this anxiety. However, the most recent edition of the “Diagnostic and Statistical Manual of Mental Disorders” (DSM-5-TR) moved OCD to its class of “Obsessive-Compulsive and Related Disorders.”
OCD is said to be childhood-onset if obsessions and compulsions occur before puberty. Interestingly, although childhood OCD more commonly affects boys, this trend reverses after puberty. Likewise, boys with childhood-onset OCD appear to be at greater risk for related conditions, including tic disorders.
Children with OCD often have less insight into their obsessions than adults and lack the capacity to understand the irrationality of their thoughts. This, combined with limited and/or developing verbal ability, can make proper diagnosis difficult.
A child’s obsessions and compulsions often differ from those of adults.
- Children with OCD often have specific obsessions related to the death of their parents.
- Children’s obsessions rarely emphasize sexual themes, although adolescents may experience a greater incidence of sexually focused obsessions.
- Children’s rituals or compulsions may be more likely to involve or be centered around family members.
- Children with OCD may hoard more frequently than adults with the disorder.
- Childhood-onset OCD also seems to signal a higher risk of tic disorders and attention-deficit/hyperactivity disorder (ADHD).
Identifying OCD in Children
The signs and symptoms of OCD in children can be categorized as obsessions and compulsions. Common obsessions among children with OCD include:
- Disturbing and unwanted thoughts or images of violent or disturbing things, like harming others
- Extreme worry about bad things happening, doing something wrong, or lying
- Feeling that things have to be “just right”
- Preoccupation with order, symmetry, or exactness
- Worries about getting sick, or getting others sick, or throwing up
Compulsions are often (but not always) related to obsessions. For example, if the child fears germs, they may be compelled to wash their hands repeatedly. Common compulsions among children with OCD include:
- Counting things over and over again
- Elaborate rituals that must be performed exactly the same way each time (i.e. a bedtime ritual)
- Excessive hand washing, showering, or brushing teeth
- Excessively repeating sounds, words, or numbers to oneself
- Ordering or rearranging objects in a particular or symmetrical way
- Repeated checking (such as re-checking that the door is locked, oven is off, or homework is done right)
- Repeatedly seeking reassurance from friends and family
OCD can co-exist with (and also be mistaken for) other disorders that include rigid routines and/or repetitive behaviors or rituals, such as:
Understanding the motivations of a child’s behavior is key to a proper diagnosis.
What Causes OCD in Preschoolers?
What triggers OCD in preschoolers and older children? Although the exact causes of OCD in children are unknown, researchers believe several factors play a role, including brain structure, early trauma, genetics, and stress.
- Brain structure: Imaging studies have found a connection between OCD and abnormalities in the frontal cortex and subcortical structures of the brain.
- Early-life trauma: Some studies have found a link between early-life trauma, such as sexual assault, and symptoms of OCD in prepubescent girls.
- Genetics: Although there’s no “OCD gene,” evidence exists for particular versions (alleles) of certain genes that may signal greater vulnerability. What’s more, OCD has been found to run in families: The closer the family member and the younger they were when symptoms started, the higher your risk.
- Stress: Stress from relationship difficulties, problems at school, and illness can be strong triggers for symptoms of OCD in children.
In a recent study, children and adolescents showed a worsening of OCD, anxiety, and depressive symptoms related to the COVID-19 pandemic and associated trauma.
Sudden-Onset OCD
In about 5% of children, OCD is caused by an autoimmune reaction within the brain known as PANDAS or autoimmune subtype. PANDAS OCD is thought to be triggered by infection with the bacteria that causes strep throat and scarlet fever. The child’s immune system becomes confused as it fights the infection and attacks the brain’s basal ganglia.
The PANDAS form of OCD has a few key characteristics that help doctors distinguish it from more typical forms of childhood OCD; these include the rapid onset of symptoms. Research has shown that only those children who are genetically predisposed to OCD or tics are vulnerable to developing this form of OCD. The PANDAS form of OCD can require different treatment.
Treating OCD in Preschoolers and Children
Seeking professional treatment is the most effective thing you can do to help your child with OCD. In most cases, the recommended treatment for childhood-onset OCD combines individual or group cognitive behavioral therapy (CBT) with medications that increase levels of serotonin, such as selective serotonin reuptake inhibitors (SSRIs).
What Is Serotonin?
Serotonin (also known as 5-hydroxytryptamine or 5-HT) is a neurotransmitter that carries signals between neurons throughout the body. It helps with mood regulation, memory, and other bodily functions. The intestines, not the brain, produce most of the body’s serotonin supply.
Cognitive Behavioral Therapy
One of the most popular and effective therapies for OCD is child-modified exposure and response prevention therapy (ERP), a type of cognitive behavioral therapy (CBT). It involves exposing children to the anxiety their obsessions provoke and then preventing the use of rituals to reduce that anxiety. This cycle of exposure and response prevention is repeated until the obsessions and/or compulsions no longer trouble the children.
Both adults and children with OCD frequently ask others to participate in their compulsions. Family members often oblige to reduce their loved one’s anxiety, especially when the person is a child. For treatment to work, compulsions must stop, and family members must be aware of this.
Preschools and older children with OCD need parental support during their CBT treatment. Evidence suggests that CBT is more successful when parents are involved.
Medications
Therapy is often effective, but it is not the only treatment option. In severe cases of childhood OCD, treatment may include a combination of CBT and medications such as SSRIs to help reduce a child’s anxiety. However, these drugs must be used cautiously in children and adolescents because they can increase the risk of suicide.
Three SSRIs are FDA-approved for use in children and adolescents with OCD:
- Luvox (fluvoxamine): Approved for children age 8 and older
- Prozac (fluoxetine): Approved for children age 8 and older
- Zoloft (sertraline): Approved for children age 6 and older
If OCD is caused by PANDAS, treatment may include the following:
- Antibiotics (penicillin, azithromycin)
- Intravenous immunoglobulin
- NSAIDs and corticosteroids
- Plasma exchange
- Tonsillectomy
Can Childhood OCD Go Away?
OCD is a chronic condition, so childhood OCD rarely just goes away on its own. According to one study, only around 4% of people with OCD experience a remission in their symptoms without treatment.
However, symptoms may improve over time as a person ages and with appropriate treatment. Learning effective coping skills can also help people cope with symptoms that may worsen during times of stress.
One recent meta-analysis found that 62% of children and teens with OCD were able to achieve remission with treatment.
Coping With OCD in Children
Parenting toddlers, preschoolers, and older children with OCD can be a challenge, but there are ways to cope. Getting informed about OCD, particularly as experienced by children, is the essential first step that every parent should take to become an effective advocate for their child and family. This can help you reduce your stress levels and follow through with at-home exposure exercises.
Other strategies you can try:
- Work on fostering a strong partnership with the professionals involved in your child’s care.
- Don’t be afraid to ask questions and inquire about resources you can take home to absorb complex new information in small bits better.
- Engage your partner and/or family. Talk about it if you’re having trouble engaging your partner in getting informed or helping with at-home exposure exercises. Don’t sweep it under the rug. Often, a partner’s reluctance to help reflects their anxiety about the situation and does not mean they don’t want to help the child.
- Seek support. Look into available resources in your community. A good starting point might be a support group where people share tips for coping with a child who has OCD.
