Red flags
- Acute-onset obsessions/compulsions with urinary frequency, choreiform movements and developmental regression — consider PANDAS/PANS and seek specialist evaluation rather than blind SSRI initiation
- Suicidal ideation, self-harm or severe depression comorbid with OCD — safety plan and treat the crisis before titrating ERP or an SSRI
- Hours of daily rituals, food or fluid avoidance from contamination fears, or weight loss — assess for medical compromise and escalate care intensity
- Bizarre, fragmented or psychosis-like fixed beliefs with no insight — reassess for a primary psychotic or medical disorder rather than labelling OCD with absent insight
- Family conflict or violence driven by accommodation demands, or school refusal from ritual avoidance — mobilise safeguarding and intensive pathways
- Sudden deterioration, neurological signs, cognitive decline or new seizures — exclude an acquired basal-ganglia or neurological disorder

Overview & Definition
Picture the eight-year-old who is late every morning because her shoelaces "do not feel right" until she reties them forty times, or the teenager who washes his hands until they bleed because a thought about germs will not leave him alone. These are not quirks or bad habits — they are the obsession–compulsion cycle that defines OCD, and children will often hide them for a long time before anyone asks the right question. [22] [17]
OCD in children is a common, treatable anxiety-spectrum disorder. Intrusive, unwanted thoughts, images or urges (obsessions) generate intense distress, and the child performs repetitive behaviours or mental acts (compulsions) to reduce that distress. The relief is brief, so the cycle repeats — often for more than an hour a day and across home, school and social life. The diagnosis is clinical, and the impairment is real even when the child looks "fine" in a brief clinic visit. [22] [9]
The single most important clinical habit is to ask directly. Children rarely volunteer their obsessions because they fear being judged or because they believe the thoughts are "crazy". A routine question — "Do you have any thoughts that bother you and keep coming back even when you don't want them?" — is the gateway that turns a hidden, disabling illness into a treatable one. [17] [22]
