Stereotypic Movement Disorder
Stereotypic movement disorder is a condition in which a person makes repetitive, purposeless movements. These can be hand waving, body rocking, or head banging. The movements interfere with normal activity or may cause bodily harm.
Cluster Number:
Wiki Number: PW213
Diagnosis: Stereotypic Movement Syndrome
US Patients:
World Patients:
Sex Ratio:
Age Onset: genetic from the mother, birth of baby boys, can occur at any age
Brain Area:
Symptoms: child repeatedly does a nonfunctional motor behavior, e.g. hand waving or head banging) that intereferes or causes the child injury
Progression: may include rocking or rhythmic movements, self-biting, self-hitting, skinpicking, thumb-sucking, nail-biting, hair-pulling,
Causes: over-production of uric acid or deficiency in the counter-base; higher risk for those with intellectual disability
Medications: Medication(s) for gout temporarily reduces it, but does not cure it; an unspecified medication may reduce (permanent) self-injury
Therapies: May be helped by non-autistic habit-reversal-training or decoupling

- Quo vadis DSM-6? An expert survey on the classification, diagnosis, and differential diagnosis of body-focused repetitive behaviorsby Steffen Moritz on October 19, 2024
BACKGROUND: Many conditions we now call body-focused repetitive behaviors (BFRBs) have been subject to research for several decades, most notably trichotillomania and skin picking. However, the American Psychiatric Association did not combine these conditions into a single category, body-focused repetitive behavior disorders (BFRBDs), until the fifth edition of the DSM (2013). Several aspects of the disorder remain uncertain and controversial. For example, ongoing debate surrounds which specific...
- Automated Analysis of Stereotypical Movements in Videos of Children With Autism Spectrum Disorderby Tal Barami on September 12, 2024
CONCLUSIONS AND RELEVANCE: This study suggests the ability of an algorithm to identify a highly diverse range of SMMs and quantify them with high accuracy, enabling objective and direct estimation of SMM severity in individual children with ASD.
- Performance of a Tic Screening Tool (MOVeIT) in Comparison to Expert Clinician Assessment in a Developmental-Behavioral Pediatrics Clinic Sampleby Jennifer A Vermilion on August 7, 2024
Youth with intellectual and developmental disabilities typically have higher rates of tics and stereotypies compared to children with otherwise typical development. Differentiating between these two pediatric movement disorders can be challenging due to overlapping clinical features, but is relevant due to distinct treatment modalities. The current study evaluated sensitivity and specificity of a tic screening measure, the Motor or Vocal Inventory of Tics (MOVeIT) in a pediatric sample enriched...
- A 32-year old lady who developed a complex generalized movement disorder in all four limbs after plasma exchange for myelitisby Anka Arora on July 27, 2024
A 32-year old lady with AQP4-Antibody positive neuromyelitis optica developed a new-onset complex movement disorder after therapeutic plasma exchange, which was initially suspected to be hypocalcemic carpo-pedal spasm. However, when her bilateral, distal predominant, paroxysmal, stereotypic, wrist and finger flexor tonic contractions did not respond to serum calcium correction, other diagnoses were considered. The patient had a dramatic response to oral carbamazepine suggesting that the tonic...
