We obtained information about the behavioral, psychiatric, and functional status of 26 children (13 males, 13 females) with juvenile neuronal ceroid lipofuscinosis (JNCL; mean age 12y 3mo [SD 3y 4mo]; range 6y 9mo to 18y 8mo). Twenty-five children…

UNLABELLED: Parents of 40 patients with Lesch-Nyhan disease completed a questionnaire detailing developmental history, life course, management, medication, factors influencing variability and topography of self-injury. Several conclusions were…

Four patients with Lesch Nyhan disease were treated with L 5 hydroxytryptophan, alone, or in combination with carbidopa, and their effect on self mutilatory behavior was compared to that observed during periods in which placebo was administered.…

Lesch-Nyhan syndrome is a rare, sex-linked, recessive disease that is accompanied by severe self-mutilation, especially finger biting. Evidence is presented suggesting that parental response patterns may contribute to the genesis of the…

The self injurious behavior of five male children with Lesch Nyhan disease was studied during three learning paradigms: punishment, positive reinforcement and time out from reinforcement following an attempt at self injury. Punishment of self injury…

Problem behaviors of individuals who had one of three chromosome deletion disorders (5p- cri-du-chat, 15q- Prader-Willi, or 17p- Smith-Magenis) were investigated. The Aberrant Behavior Checklist was used. Results were contrasted with those of two…

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…

Patients with 22q11DS are at risk of behavioral problems and cognitive impairment. Recent studies suggest a possible intellectual decline in 22q11DS children. To date it is unknown if cognitive development is related to the behavioral problems in…

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…

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…

The early development of self-injurious behaviour in three young boys (aged 17, 25, and 30 months at start of study) with Lesch-Nyhan syndrome was examined by means of parental interviews and by direct observations completed at 3 to 4 monthly…

We surveyed 64 individuals with the diagnosis of Brachmann-de Lange syndrome (BDLS) to determine the natural course and cause of the disorder. The 64 individuals were ascertained through membership in a national organization, the Cornelia de Lange…

Sleep disorders were investigated in 40 children with tuberous sclerosis (TS) and compared with those found in non-disabled children and those reported in a mixed group with learning disabilities. Significantly higher levels of sleep disturbance were…

Researchers have argued that individuals who show self-restraint are more likely to show self-injurious behavior (SIB) that is compulsive. Self-injurious behavior, self-restraint, and compulsive behaviors have been described as features of Cornelia…

To describe clinical and neurodevelopmental phenotypes of Costello syndrome, we performed a retrospective review of the clinical records and findings in 10 children with Costello syndrome. All patients showed significant postnatal growth retardation…

Lesch-Nyhan disease (LND) is a genetic disorder that has characteristic metabolic, neurologic, and behavioral features. There are multiple behavioral problems including impulsivity, aggressiveness, and severe recurrent self-injurious behavior (SIB).…

Children with the 22q11.2 deletion syndrome (22q11DS) are at an increased risk of psychiatric problems from pre-adolescence; little is known, however, about behavioral problems at a preschool age and the relationship between speech and behavior in…

Behavioral problems are common in children with tuberous sclerosis complex (TSC) and can be challenging to manage at home. Standardized measures were used to assess behavior in 99 pediatric patients with TSC and to evaluate parenting stress in their…

Neurobehavioral and developmental issues with a broad range of deficits are prominent features of Cornelia de Lange syndrome (CdLS), a disorder due to disruption of the cohesin protein complex. The etiologic relationship of these clinical findings to…

BACKGROUND: Tuberous sclerosis complex is a multisystem disorder that includes a range of tuberous sclerosis associated neuropsychiatric disorders (TAND). The lifetime prevalence rates of TAND are very high; yet surveys suggest that the majority of…

Four cases of the Lesch Nyhan syndrome found in the Tokyo area were given L 5 hydroxytryptophan orally. L 5 hydroxy tryptophan relieved self mutilation effectively without causing any side effects. However this substance did not alleviate…

BACKGROUND: There has been limited empirical research into the environmental causes of self-injury in Cornelia de Lange syndrome. The present study examined the variability of self-injurious behaviour in Cornelia de Lange syndrome across…

AIM Careful study and accurate description of behaviour are important to understand developmental challenges for individuals with Cornelia de Lange syndrome (CdLS). Here we present a systematic review of current understanding of behaviour in CdLS.…

The present study aimed to increase the knowledge about Wolf-Hirschhorn syndrome (WHS), especially concerning motor function, autism spectrum disorders (ASD), and adapted behavior, but also regarding clinical symptoms in general. Motor function was…

The results of a survey given to parents with Sanfilippo syndrome (MPS III) children (n = 30) are described with an emphasis in several areas. Developmental and degenerative patterns are outlined in detail and contrasted with developmental milestones…

Background: Mowat-Wilson Syndrome (MWS) is caused by deletion/mutation of the ZEB2 gene on chromosome 2q22. MWS is characterized by a distinctive facial appearance, severe intellectual disability and other anomalies, e.g. seizures and/or Hirschsprung…

In a series of patients with the Lesch-Nyhan syndrome a pharmacologic attempt was made to alter the balance of biogenic amines in the central nervous system by increasing the level of serotin. Patients were treated with 5-hydroxytryptophan in…

Cornelia de Lange syndrome is reported to be associated with self-injurious behavior (SIB) and social avoidance. We used analog methodology to examine the effect of manipulating adult social contact on social communicative behaviors and SIB in 16…
