Dr. Mimi XuChild & Adolescent Psychiatrist
Specialist child, adolescent, and perinatal psychiatry for obsessive-compulsive disorder. Evidence-based assessment, diagnosis, and treatment planning via secure telehealth across Australia.
Obsessive-Compulsive Disorder (OCD) is a mental health condition characterised by intrusive, distressing thoughts (obsessions) and repetitive behaviours or mental acts (compulsions) performed to reduce the anxiety those thoughts cause. Unlike everyday worries or perfectionism, OCD obsessions feel uncontrollable and consume significant time, often more than an hour per day.
OCD typically begins in childhood, adolescence, or early adulthood. In children, it can look very different to the adult presentation. A child may not yet have language for what they are experiencing, and the compulsions may appear as ritualistic play, repeated questioning, or avoidance of specific objects, foods, or routines. Parents often notice the behaviours long before the underlying obsessions are explained.
OCD affects roughly 1 to 3 percent of Australians across the lifespan. It is highly treatable with evidence-based interventions, but the average gap between symptom onset and accurate diagnosis is often years. Early specialist assessment significantly improves long-term outcomes, particularly in children and adolescents.
Common Signs of OCD
Common ways OCD can present
Persistent fear of germs, dirt, or illness leading to excessive handwashing, showering, or avoidance of touching shared surfaces. In children, this may present as sudden refusal to use school bathrooms or eat foods touched by others.
Repeatedly checking locks, appliances, or homework, or asking the same question many times in a row. Children may need parents to reassure them dozens of times a night that nothing bad will happen.
A driving need for objects to be aligned or actions to feel "just right." Tasks like getting dressed or finishing homework can take hours because steps must be repeated until the feeling resolves.
Distressing, unwanted thoughts about harm, religion, sexuality, or relationships that feel completely against the person's values. The distress comes from the thoughts being so out of character. These are extremely common but often hidden due to shame.
Counting, praying, repeating phrases silently, or mentally "undoing" a thought. These are often invisible to family members but can occupy hours each day and seriously interfere with school and concentration.
Intrusive thoughts about harm coming to a baby, or compulsions around feeding, sleep safety, or hygiene. Affects up to 1 in 10 new mothers. Distinct from postnatal depression and highly responsive to treatment when correctly identified.

Our free screening tools can help with that first step.
ADHD · Autism · Anxiety · Depression · PTSD
Take a Free ScreeningFirst-line evidence-based treatment is Exposure and Response Prevention (ERP), a specialised form of Cognitive Behavioural Therapy delivered by a trained psychologist or psychiatrist. ERP works by gradually exposing the person to the thoughts or situations that trigger obsessions, while supporting them to resist performing the compulsion. It is challenging work but produces durable improvement for most patients.
For moderate-to-severe OCD, or when ERP alone is insufficient, SSRI medication is the most evidence-supported pharmacological approach. SSRIs for OCD are typically prescribed at higher doses than for depression and may take 8 to 12 weeks to show full effect. Medication and ERP combined are more effective than either alone for severe presentations.
At Lionheart, our role is comprehensive psychiatric assessment, accurate diagnosis (including ruling out conditions that mimic OCD), and treatment planning. We coordinate with psychologists who deliver ERP, manage medication where appropriate, and review progress over time. For children, we work collaboratively with parents and schools.

Choose a convenient time for your telehealth consultation.
Meet with your psychiatrist via secure video from home.
OCD often co-occurs with anxiety disorders, ADHD, autism spectrum disorder, depression, or tic disorders. A thorough psychiatric assessment matters because treatment plans differ based on what else is present. For example, OCD with co-occurring autism may need adapted ERP techniques, and OCD with tics may benefit from a different first-line medication choice.
Telehealth is well-suited to OCD assessment and ongoing review. Our psychiatrists conduct comprehensive interviews via secure video, review collateral information from parents, schools, and prior clinicians, and provide detailed written reports. For children, having the assessment from home often reduces the additional stress of attending an unfamiliar clinic.
Perinatal and postnatal OCD deserve special mention. Intrusive thoughts about harm to a baby are deeply distressing for new mothers and frequently kept secret due to shame or fear of judgement. These thoughts are not predictive of action and respond well to treatment. Dr Joanna Blades specialises in perinatal psychiatry and assesses women across pregnancy and the postpartum period at Lionheart.

Frequently Asked Questions
Common questions about OCD
OCD diagnosis requires a clinical interview with a qualified mental health professional. A psychiatrist will assess the type, frequency, and duration of obsessions and compulsions, the distress and time involvement they cause, and whether other conditions might better explain the symptoms. Validated rating scales such as the Y-BOCS (Yale-Brown Obsessive Compulsive Scale) are often used to quantify severity.
OCD can begin as early as ages 6 to 8 in children, with a second peak in late adolescence. Early-onset childhood OCD often has a stronger genetic component and may run in families. If your child has rituals or worries that take significant time and cause distress, an assessment is worthwhile regardless of age.
Yes. For mild-to-moderate OCD, Exposure and Response Prevention (ERP) therapy alone is often effective, especially in children and adolescents where avoiding medication is preferred where possible. For severe OCD or when ERP alone is insufficient, SSRI medication is added. The decision is individual and based on severity, age, and family preference.
Almost everyone experiences intrusive thoughts. The difference in OCD is the distress they cause and the compulsive responses (mental or physical) used to neutralise them. Having a violent or taboo intrusive thought does not mean someone is dangerous — in OCD, the distress is precisely because the thought is so out of character. This is one of the most misunderstood aspects of the condition.
Perinatal OCD involves intrusive, often horrifying thoughts about harm to the baby (typically through accident or contamination), accompanied by compulsions like repeated checking or hyper-vigilant caregiving. It is distinct from postnatal depression and from postpartum psychosis. Mothers with perinatal OCD are not at risk of acting on the thoughts — they are deeply distressed by them. It is highly treatable when correctly identified.
