Stereotyped Movement Disorder
Screening & diagnostic pathway for Stereotyped Movement Disorder (under 7)
For children under 7, Stereotyped Movement Disorder (ICD-11 6A06) follows a pathway of developmental surveillance, structured screening, differential work-up to exclude tics and epilepsy, co-morbidity screening for ASD/IDD/ADHD, and multidisciplinary clinician-confirmed diagnosis with impairment and self-injury grading.
A child who flaps, rocks or self-stimulates rhythmically presents a familiar diagnostic fork: benign developmental stereotypy, or something warranting structured pathway work?
In short
Stereotyped Movement Disorder (ICD-11 6A06) is a clinical diagnosis of exclusion: repetitive, purposeless, rhythmic motor behaviours (hand-flapping, body-rocking, head-banging, self-biting) that are developmentally inappropriate, persistent and functionally impairing or self-injurious. In under-7s the pathway is surveillance → structured screen → differential work-up → multidisciplinary diagnosis, prioritising exclusion of seizures, tics, sensory disorders and self-injurious behaviour secondary to other neurodevelopmental conditions.The pathway
1. Surveillance & history. Characterise onset (often <3 years), topography, frequency, triggers, suppressibility and whether movements are non-distressing to the child. Document family history and developmental trajectory.2. Differentiate. Stereotypies are typically rhythmic, fixed-pattern, bilateral, suppressible on distraction and absent in sleep — distinguishing them from tics (preceded by urge, waxing/waning, fragmentary) and from epileptic phenomena. Any paroxysmal, stereotyped events with altered awareness, autonomic features or sleep occurrence warrant prompt neurology referral and EEG before a movement-disorder label is applied.
3. Co-morbidity screen. Screen for ASD, intellectual developmental disorder, ADHD and sensory processing differences, since secondary stereotypies are common. Assess self-injury severity.
4. Multidisciplinary diagnosis. Confirm via paediatric/developmental clinician plus structured functional assessment; grade impairment and self-injury risk to guide behavioural and environmental management.

What to watch
Paroxysmal stereotyped events with altered awareness, autonomic features or occurring in sleep — these need prompt neurology referral and EEG, not a movement-disorder label.
Try this at home
Note whether the movements stop when the child is distracted or engaged and whether they occur during sleep — suppressibility and absence in sleep favour stereotypy over seizure.

Frequently asked
How is stereotypy distinguished from a tic in a young child?
Stereotypies are rhythmic, fixed-pattern, bilateral, often present from before age 3, suppressible on distraction and absent in sleep. Tics are typically preceded by a premonitory urge, are fragmentary, wax and wane over time, and emerge later. Persistent diagnostic uncertainty warrants specialist developmental or neurology review.
When should I refer for EEG rather than a movement-disorder assessment?
Refer promptly for neurology assessment and EEG when stereotyped events involve altered awareness, autonomic changes, occur during sleep, or are not suppressible — epileptic phenomena must be excluded before a Stereotyped Movement Disorder label is applied.
Are stereotypies always pathological?
No. Simple, transient stereotypies are common and developmentally typical in young children. A 6A06 diagnosis requires that movements are developmentally inappropriate, persistent, and either functionally impairing or self-injurious.
