Hyperkinetic stereotyped movements in a boy with biallelic CNTNAP2 variants.

Ital J Pediatr 2021 Oct 12;47(1):208. Epub 2021 Oct 12.

Pediatric Neurology and Muscular Diseases Unit, IRCCS Istituto Giannina Gaslini, Genoa, Italy.

Background: Heterozygous variants in CNTNAP2 have been implicated in a wide range of neurological phenotypes, including intellectual disability (ID), epilepsy, autistic spectrum disorder (ASD), and impaired language. However, heterozygous variants can also be found in unaffected individuals. Biallelic CNTNAP2 variants are rarer and cause a well-defined genetic syndrome known as CASPR2 deficiency disorder, a condition characterised by ID, early-onset refractory epilepsy, language impairment, and autistic features.

Development of Two Dimensional Measures of Restricted and Repetitive Behavior in Parents and Children.

J Am Acad Child Adolesc Psychiatry 2017 01 3;56(1):51-58. Epub 2016 Nov 3.

Cleveland Clinic Children's Hospital Center for Pediatric Behavioral Health, Cleveland.

Objective: Restricted and repetitive behaviors (RRBs) are a heterogeneous set of behaviors common across a wide range of neurodevelopmental disorders (NDDs) and neuropsychiatric disorders (NPDs) that extend well into the general population. This study introduces 2 dimensional measurements of RRBs for use in typical and clinical populations from infancy to adulthood.

Method: The Childhood Routines Inventory-Revised (CRI-R) and the Adult Routines Inventory (ARI) were created and administered online to a nationally representative cohort of 3,108 parents with 3,032 children (range 12 months to 17 years 11 months). Read More

Rhythmic movement disorder in childhood: An integrative review.

Sleep Med Rev 2017 10 26;35:62-75. Epub 2016 Aug 26.

Faculty of Medicine, University of Southampton, UK; Southampton Children's Hospital, UK.

Rhythmic movement disorder consists of repetitive stereotypic movements, such as head banging or body rocking, that recur every second or so and may last from a few minutes to hours, usually prior to sleep onset. This review of childhood rhythmic movement disorder highlights the lack of systematic research into core aspects of the condition, relying heavily on small case series or case reports. Interpretation is further limited by almost universal failure to confirm the core diagnostic criteria (C) of the International classification of sleep disorders (III), namely that the rhythmic movements should have clinical consequences.

[Non-epileptic motor paroxysmal phenomena in wakefulness in childhood].

Rev Neurol 2013 Sep;57 Suppl 1:S105-14

Hospital de Pediatria SAMIC. Prof. Dr. J.P. Garrahan, Buenos Aires, Argentina.

Paroxysmal events in childhood are a challenge for pediatric neurologists, given its highly heterogeneous clinical manifestations, often difficult to distinguish between phenomena of epileptic seizure or not. The non-epileptic paroxysmal episodes are neurological phenomena, with motor, sensory symptoms, and/or sensory impairments, with or without involvement of consciousness, epileptic phenomena unrelated, so no electroencephalographic correlative expression between or during episodes. From the clinical point of view can be classified into four groups: motor phenomena, syncope, migraine (and associated conditions) and acute psychiatric symptoms. Read More

Developmental and benign movement disorders in childhood.

Mov Disord 2010 Jul;25(10):1317-34

Centre d'Investigation Clinique, INSERM, AP-HP, Paris, France.

Developmental and benign movement disorders are a group of movement disorders with onset in the neonatal period, infancy, or childhood. They are characterized by the absence of associated neurological manifestations and by their favorable outcome, although developmental abnormalities can be occasionally observed. Knowledge of the clinical, neurophysiological, and pathogenetic aspects of these disorders is poor. Read More

Trichotillomania (hair pulling disorder), skin picking disorder, and stereotypic movement disorder: toward DSM-V.

Depress Anxiety 2010 Jun;27(6):611-26

Department of Psychiatry, University of Cape Town, Rondebosch, Cape Town, South Africa.

In DSM-IV-TR, trichotillomania (TTM) is classified as an impulse control disorder (not classified elsewhere), skin picking lacks its own diagnostic category (but might be diagnosed as an impulse control disorder not otherwise specified), and stereotypic movement disorder is classified as a disorder usually first diagnosed in infancy, childhood, or adolescence. ICD-10 classifies TTM as a habit and impulse disorder, and includes stereotyped movement disorders in a section on other behavioral and emotional disorders with onset usually occurring in childhood and adolescence. This article provides a focused review of nosological issues relevant to DSM-V, given recent empirical findings. Read More

Neurologic and developmental features of the Smith-Magenis syndrome (del 17p11.2).

Pediatr Neurol 2006 May;34(5):337-50

Department of Pediatrics (Genetics and Metabolism), Georgetown University, Washington, DC 20007, USA.

The Smith-Magenis syndrome is a rare, complex multisystemic disorder featuring, mental retardation and multiple congenital anomalies caused by a heterozygous interstitial deletion of chromosome 17p11.2. The phenotype of Smith-Magenis syndrome is characterized by a distinct pattern of features including infantile hypotonia, generalized complacency and lethargy in infancy, minor skeletal (brachycephaly, brachydactyly) and craniofacial features, ocular abnormalities, middle ear and laryngeal abnormalities including hoarse voice, as well as marked early expressive speech and language delays, psychomotor and growth retardation, and a 24-hour sleep disturbance.

Continuous giggling and autistic disorder associated with hypothalamic hamartoma.

Epileptic Disord 2003 Mar;5(1):31-7

Clinical Neurophysiology section, Niño Jesús University Hospital, Madrid, Spain.

We present the case of a child affected since early infancy from recurring episodes of giggling mixed with stereotypical behaviours, mingled with head drops, and eventually with falls, in the context of an autistic disorder. Scalp video-EEG recordings revealed an epileptic encephalopathy with generalized slow spike-and-wave complexes alternating with electrodecremental periods, which generally corresponded to the onset of the aforementioned clinical sequences. A resection of a hypothalamic hamartoma was achieved at the age of two. Read More

Jactatio capitis nocturna with persistence in adulthood. Case report.

Arq Neuropsiquiatr 1998 Sep;56(3B):655-7

Centro de Estudos do Sono (CES) do Hospital das Clínicas (HC) da Faculdade de Medicina, Universidade de São Paulo (FMUSP), Brasil.

Rhythmic movement disorder, also known as jactatio capitis nocturna, is an infancy and childhood sleep-related disorder characterized by repetitive movements occurring immediately prior to sleep onset and sustained into light sleep. We report a 19-year-old man with a history of headbanging and repetitive bodyrocking since infancy, occurring on a daily basis at sleep onset. He was born a premature baby but psychomotor milestones were unremarkable. Read More

Physical activity play: the nature and function of a neglected aspect of playing.

Child Dev 1998 Jun;69(3):577-98

Department of Educational Psychology, University of Minnesota, Minneapolis 55455, USA.

In this review, we consider the nature and possible developmental functions of physical activity play, defined as a playful context combined with a dimension of physical vigor. We distinguish 3 kinds of physical activity play, with consecutive age peaks: rhythmic stereotypies peaking in infancy, exercise play peaking during the preschool years, and rough-and-tumble play peaking in middle childhood. Gender differences (greater prevalence in males) characterize the latter 2 forms. Read More

[A neurologic model of early infantile autism].

M Segawa

No To Hattatsu 1989 Mar;21(2):170-80

Based on the abnormalities in sleep-wakefulness cycle of early infantile autism, the author discussed its pathophysiology focusing on its main lesion in the raphe nuclei. These neurons, located in the midline portion of the brainstem send their axons to various neurons of the upper and lower nervous systems, including the locus coeruleus and the dopamine neurons of the tegmentum, the former having a broad innervation and the latter a restricted area in the central nervous system. These monoaminergic neurons modulate the functions of the involved neurons and regulate their functional and structural maturation in the early developmental course. Read More

[Early childhood autism from the behavioral biologic and neurophysiologic viewpoint].

H Gebelt

Psychiatr Neurol Med Psychol (Leipz) 1983 Jan;35(1):1-9

Assuming that the autistic syndromes my be attributed to disturbances in information input and processing, the results of the most important behavioural and neurophysiological investigations made during the past 10 to 15 years are introduced and discussed in brief. Etiological questions are raised, too. Disturbed perception in different sensory systems may also be considered as partial disablement. Read More
