A postal questionnaire was used to study 49 individuals with Cornelia de Lange syndrome (including both the classical and the mild forms) to ascertain behavioural phenotype. Ages ranged from early childhood to adulthood (mean age, 10.2 years; SD,…

Rett syndrome (RTT), a rare but severe neurological disorder is associated with a mutation in the methyl CpG binding protein 2 (MECP2) gene on the X chromosome occurring in 1:9000 live female births. Apparently normal development is followed by a…

Overnight polysomnography was performed in 10 subjects with tuberous sclerosis (TS) and partial epilepsy in order to investigate the relationships between sleep organization, sleep disorders and epilepsy. Sleep architecture abnormalities were…

Research indicates that approximately 40% to 70% of children with disabilities are identified and treated for feeding difficulties such as reflux. The available literature on children with trisomy 18 does not describe feeding needs or treatment. The…

To test the validity and reliability of the scale for the assessment and rating of ataxia (SARA) in Friedreich ataxia (FRDA). SARA is limited to eight items and can be performed rapidly. Ninety-six patients with a molecular genetic diagnosis of FRDA…

PURPOSE: Rett syndrome is a severe neurodevelopmental disorder mainly affecting females and usually linked to mutations in the methyl-CpG-binding protein 2 gene, with an estimated prevalence of 1 in 10,000 live female births. Clinical features which…

Stereotypic hand movements are a feature of Rett Syndrome but few studies have observed their nature systematically. Video data in familiar settings were obtained on subjects (n = 144) identified from an Australian population-based database. I-land…

Systematic data from a multidisciplinary clinical assessment of a large series of females with Rett syndrome (RS; n=87) is presented. Participants' ages ranged from 2 years 1 month to 44 years 10 months. Areas assessed included oromotor skills,…

As part of a wider study to investigate the behavioral phenotype of a national sample of girls and women with Rett syndrome (RTT) in comparison to a well-chosen contrast group and its relationship to parental well-being, the development, clinical…

BACKGROUND: The aim was to gain a UK national sample of people with Rett syndrome (RTT) across the age range and compare their characteristics using a variety of relevant behavioural measures with a well-chosen contrast group. METHODS: The achieved…

The aim was to observe the behaviour of a sample of females with RTT and explore how it was organized in relation to environmental events. Ten participants, all with a less severe form of classic (n = 9) or atypical (n = 1) Rett syndrome (RTT), were…

In the current study, the authors examined whether the fatigue level of children diagnosed with cri du chat syndrome was associated with the expression of autistic symptoms. Sixty-nine children with cri du chat syndrome were compared with 47 children…

The aim of the present study was to determine the prevalence and frequency of stereotypy, self-injurious behaviour (SIB), and aggression in children and adults with Cri du Chat syndrome (CCS), and to investigate the relationship between SIB,…

Objectives: We sought to document the prevalence and nature of sleep-disordered breathing (SDB) in individuals with Friedreich ataxia (FRDA) as well as establish the relationship, if any, between SDB and clinical parameters of FRDA. Methods:…

Friedreich Ataxia (FRDA) is the commonest inherited ataxia. Clinical trials of pharmaceuticals are increasingly being conducted in this condition. This requires the most accurate outcome measures to enable trials to be conducted with a minimum number…

Twenty children with cri-du-chat syndrome were assessed on the Vineland Adaptive Behavioural Scales. Strengths within rather than between the adaptive domains were identified with posthoc analyses revealing the main differences to lie within the…

Developmental and behavioural characteristics were assessed in 27 children with cri du chat syndrome using the Society for the Study of Behavioural Phenotypes questionnaire, which gave information on prenatal and perinatal conditions, neurological…

BACKGROUND AND PURPOSE: The purpose of this study was to describe gait parameters in children and adolescents with a diagnosis of Friedreich ataxia (FA) and examine the relationship between disease severity, measured by the Friedreich Ataxia Rating…

PubMed Central Canada (PMC Canada) provides free access to a stable and permanent online digital archive of full-text, peer-reviewed health and life sciences research publications. It builds on PubMed Central (PMC), the U.S. National Institutes of…

The mucopolysaccharide disorders (MPS) are a group of recessively inherited metabolic disorders resulting in progressive physical and cognitive decline. MEDLINE, PsycINFO and Embase databases were searched, alongside manual screening, to identify…

Costello syndrome is a rare genetic condition caused by heterozygous alterations in HRAS and characterized by multi-system abnormalities. Individuals with Costello syndrome usually present with severe feeding difficulties in infancy, short stature,…

Movement impairment is a fundamental but variable component of the Rett syndrome phenotype. This study used video supplemented by parent report data to describe the gross motor profile in females with Rett syndrome (n=99) and to investigate the…

Objectives - It has been assumed that the sterotyped hand movements in Rett syndrome are symmetrical, midline and that they prevent purposeful use of the hands. Their relationship with respiration has not been previously explored. Material and…

Background Little is known regarding the neuropsychological profiles of pediatric patients with mitochondrial diseases or their parents, information that is crucial for improving the quality of life (QOL) for both patients and parents. We aimed to…

The study of selective attention and its influence on communication in patients with Rett Syndrome (RS), in which communication abilities are impaired is particularly relevant. The aim of this study was to analyse attention and communication…

BACKGROUND: Velocardiofacial syndrome (VCFS), a genetic deletion condition with numerous cognitive sequelae, is associated with a high rate of psychiatric disorders in childhood. More recently, VCFS has been identified as a high-risk factor for…

Rett syndrome, a progressive neurodegenerative disorder described only in female subjects, is manifested by a wide spectrum of behavioral and motor abnormalities. We studied 32 patients with this disorder, ages 30 months to 28 years old, and…

Rett syndrome is a rare but severe neurological disorder typically associated with a mutation in the MECP2 gene. We describe change in gross motor function over 3 to 4 years for 70 subjects participating in the Australian Rett Syndrome Database.…

AIMS: To determine the incidence, manifestations, and best management of sleep disturbance in Sanfilippo syndrome (mucopolysaccharidosis (MPS) type III). METHODS: Families were ascertained through the MPS societies of Australasia, the UK, and the…

Sanfilippo syndrome (mucopolysaccharidosis type III) is the commonest mucoploysaccharidosis. It causes neurodegeneration with often profound sleep and behavioral disturbance. Management of the sleep disturbance is difficult and inconsistent. In this…
