Summary
This study examines the classification of stereotyped movement disorder, body-focused repetitive behaviors, and nonsuicidal self-injury in ICD-11. It addresses nosological questions regarding their relationships within mental and behavioral disorder classifications.
Area of Science:
- Psychiatry
- Neuroscience
- Mental Health Classification
Background:
- Current proposals for ICD-11 classify stereotyped movement disorder under neurodevelopmental disorders.
- The World Health Organization (WHO) ICD-11 Working Group suggests grouping body-focused repetitive behavior disorders within obsessive-compulsive and related disorders (OCRD).
- DSM-5 classifies trichotillomania and excoriation disorder under OCRD, with body-focused repetitive behavior disorder under other specified forms of OCRD, and nonsuicidal self-injury as a separate category for further study.
Purpose of the Study:
- To explore unresolved nosological questions concerning the relationships among stereotyped movement disorder, body-focused repetitive behavior disorders, and nonsuicidal self-injury.
- To provide preliminary answers related to the ICD-11 classification of mental and behavioral disorders.
- To clarify the placement of these conditions within the evolving ICD-11 framework.
Main Methods:
- Comparative analysis of proposed ICD-11 classifications.
- Review of DSM-5 diagnostic criteria and groupings.
- Examination of the relationships between stereotyped movement disorder, body-focused repetitive behaviors, and nonsuicidal self-injury.
Main Results:
- Stereotyped movement disorder is proposed for neurodevelopmental disorders in ICD-11, with a self-injury qualifier.
- Body-focused repetitive behavior disorders (e.g., trichotillomania, skin picking) are proposed for OCRD in ICD-11.
- Differences exist between ICD-11 proposals and DSM-5 regarding the classification of these related conditions.
Conclusions:
- The classification of stereotyped movement disorder, body-focused repetitive behaviors, and nonsuicidal self-injury presents ongoing nosological challenges.
- ICD-11 proposals aim to refine the categorization of these disorders, particularly within neurodevelopmental and OCRD clusters.
- Further research is needed to definitively establish the relationships and optimal classification for these conditions in ICD-11.

Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.

01:21Huntington Disease l: Introduction
13
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show...

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of...
