Hans Heinze and the Research Programme of the German Association of Child Psychiatry and Therapeutic Education 1942-1945 Upon its foundation in 1940, Paul Schröder, full professor for psychiatry in Leipzig, was the first president of the German Society for Child Psychiatry and Therapeutic Education (DGKH). Following his death in 1941, his student Hans Heinze (Brandenburg/H.) succeeded him, prevailing over Werner Villinger (Breslau). The principal task of the DGKH was considered to be the exploration of the genetic origins of intellectual disabilities and behavioural disorders among children and adolescents...

A Multi-arm Placebo-controlled Study with Glutamic Acid Conducted in Rostock in 1953/1954 Glutamic acid was commonly used in the treatment of intellectually disabled children in the 50s. Koch reported first results of an observation of 140 children treated with glutamic acid in 1952. In this line is the multi-arm placebo-controlled study reported here. The original study protocols were available. 58 children with speech problems who attending a school of special needs received glutamic acid, or vitamin B, or St...

PRR12 encodes a proline-rich protein nuclear factor suspected to be involved in neural development. Its nuclear expression in fetal brains and in the vision system supports its role in brain and eye development more specifically. However, its function and potential role in human disease has not been determined. Recently, a de novo t(10;19) (q22.3;q13.33) translocation disrupting the PRR12 gene was detected in a girl with intellectual disability and neuropsychiatric alterations. Here we report on three unrelated patients with heterozygous de novo apparent loss-of-function mutations in PRR12 detected by clinical whole exome sequencing: c...

In this article, the authors offer recommendations for behavior analysts on how to treat adults with intellectual and developmental disabilities (IDD) with dignity. Initially, the importance of treating adults with disabilities with dignity is emphasized in terms of the impact on people with IDD, their family members, behavior analysts and other service providers, and the behavior analysis field in general. The recommendations are based primarily on the authors' professional and personal experiences along with similar experiences of others involved either personally or professionally in the disability field...

Facilitating the use of public transportation enhances opportunities for independent living and competitive, community-based employment for individuals with intellectual and developmental disabilities (IDD). Four young adults with IDD were taught through total-task chaining to use the Google Maps application, a self-prompting, visual navigation system, to take the bus to locations around a college campus and the community. Three of four participants learned to use Google Maps to independently navigate public transportation...

Children with intellectual disabilities (ID) often have difficulty in sentence reading and comprehension. Previous studies have shown that training in segment-unit reading (SUR) facilitates the acquisition of sentence reading comprehension skills for Japanese students with ID. However, it remains unknown whether SUR training is also effective for individuals unable to read sentences and can generalize to untrained sentences. In this study, we examined the improvement and generalization of sentence reading accuracy and comprehension for two children with ID through SUR training with listening comprehensible sentences...

Here we report a Japanese patient with new compound heterozygous truncating variants in the PCDH12 gene. As compared to the previously reported families who had congenital microcephaly, intrauterine growth retardation, intracranial calcification, and neonatal seizure associated with dysplasia of the midbrain-hypothalamus-optic tract, the present patient showed no midbrain-hypothalamus dysplasia or congenital/postnatal microcephaly, but dyskinetic cerebral palsy and severe intellectual disability as well as multifocal epilepsy...

BACKGROUND: Chromosomal microarray analysis (CMA) is recommended as the first-tier clinical diagnostic test for individuals with developmental disabilities. In addition to detecting copy number variations, CMA platforms with single nucleotide polymorphism probes can detect large homozygous regions within the genome, which represent potential risk for recessively inherited disorders. METHODS: To determine the frequency in which pathogenic or likely pathogenic variants can be detected in these regions of homozygosity, we performed whole exome sequencing (WES) in 53 individuals where homozygosity was detected by CMA...

BACKGROUND: Low-education attainment is associated with worse cognitive performance in multiple sclerosis (MS) patients, and possibly with a lower cognitive reserve and/or increased inflammatory activity. Cognitive reserve refers to the capability of a source of intellectual enrichment in attenuating a negative effect of a disease-related factor; while the inflammatory activity is often related to T2-lesion load (T2-LL) increase. OBJECTIVE: To disentangle the effects of cognitive reserve and an increased T2-LL in MS-patients with low-education levels...

Kleefstra syndrome, a disease with intellectual disability, autism spectrum disorders and other developmental defects is caused in humans by haploinsufficiency of EHMT1. Although EHMT1 and its paralog EHMT2 were shown to be histone methyltransferases responsible for deposition of the di-methylated H3K9 (H3K9me2), the exact nature of epigenetic dysfunctions in Kleefstra syndrome remains unknown. Here, we found that the epigenome of Ehmt1+/- adult mouse brain displays a marked increase of H3K9me2/3 which correlates with impaired expression of protocadherins, master regulators of neuronal diversity...

The signaling scaffold protein GIT1 is expressed widely throughout the brain, but its function in vivo remains elusive. Mice lacking GIT1 have been proposed as a model for attention deficit-hyperactivity disorder, due to alterations in basal locomotor activity as well as paradoxical locomotor suppression by the psychostimulant amphetamine. Since we had previously shown that GIT1-knockout mice have normal locomotor activity, here we examined GIT1-deficient mice for ADHD-like behavior in more detail, and find neither hyperactivity nor amphetamine-induced locomotor suppression...

Life grids have been used in qualitative studies for the last two decades. They provide an activity which researcher and participant can focus their attention on, help build rapport, and reduce the control the researcher may hold within a session. Here we describe the novel use of life grids at the end of a data collection phase. Used in this previously unreported way, life grids assisted the closure of the data collection phase by summarizing the data collection and marking departure from the field. Creation of a life grid produced a tangible outcome, evidencing the work undertaken within the data collection period...

Adaptive functioning (AF) has been overlooked in the assessment of intellectual disability within the UK Prison Service, primarily because there are no reliable and valid measures of AF suitable for use with prison populations. This position is incompatible with the obligation of Her Majesty's Prison and Probation Service to provide specialist interventions for individuals with intellectual disabilities. This study assessed the psychometric properties of the Adaptive Functioning Assessment Tool (AFAT), a new measure of AF developed for use in prisons...

Hundreds of genes are mutated in non-syndromic intellectual disability (ID) and autism spectrum disorder (ASD), with each gene often involved in only a handful of cases. Such heterogeneity can be daunting, but rare recessive loss of function (LOF) mutations can be a good starting point to provide insight into the mechanisms of neurodevelopmental disease. Biallelic LOF mutations in the signaling scaffold CC2D1A cause a rare form of autosomal recessive ID, sometimes associated with ASD and seizures. In parallel, we recently reported that Cc2d1a -deficient mice present with cognitive and social deficits, hyperactivity and anxiety...

The objective of this study was to investigate the adaptive functioning of adults who had a slight to moderate intellectual deficiency, in regard of age and intellectual quotient (IQ). Cognitive and adaptive functioning were evaluated using the WAIS and VINELAND scales in 16 adults who accepted to participate in this study. We found a correlation between global IQ and each domain of the adaptive score, mostly communication skills. We also found that there was an age effect on socialization skills. Most skills were learned during infancy and adolescence, especially communication skills, which are highly stable at different ages and highly correlated with IQ...

Down syndrome (DS) is the most frequent genetic cause of developmental abnormalities leading to intellectual disability. One notable phenomenon affecting the formation of nascent neural circuits during late developmental periods is developmental switch of GABA action from depolarizing to hyperpolarizing mode. We examined properties of this switch in DS using primary cultures and acute hippocampal slices from Ts65Dn mice, a genetic model of DS. Cultures of DIV3-DIV13 Ts65Dn and control normosomic (2 N) neurons were loaded with FURA-2 AM, and GABA action was assessed using local applications...

Outpatient Psychotherapy for Children and Adolescents with Intellectual Disability The psychiatric morbidity risk for people with intellectual disability is considerably increased. Psychotherapy is considered as one possible treatment. Among experts the caresituation is described as substantial insufficient. This study investigated the perspective of psychotherapists for children and adolescents in the German state North Rhine-Westphalia regarding the care situation of outpatient psychotherapy for children and adolescents with intellectual disability...

[Purpose] Rett syndrome is a severe neurodevelopmental disease; individuals typically have no verbal skills or purposeful hand movements. In clinical settings, knowledge of their interests would be helpful for therapy. Therefore, we investigated the interests of Rett syndrome patients. [Subjects and Methods] In 2016, we sent a questionnaire regarding the interests of individuals with Rett syndrome to 1,016 directors of schools for special needs education and 204 directors of rehabilitation departments (130 facilities for persons with severe motor and intellectual disabilities, 73 wards for patients with severe motor and intellectual disabilities, and the National Hospital Organization and National Center Hospital, and the National Center of Neurology and Psychiatry) in Japan...

BACKGROUND: The KCNMA1 gene encodes the α-subunit of the large conductance, voltage and calcium-sensitive potassium channel (BK channels) which plays an important role in neuronal excitability. Heterozygous mutations in KCNMA1 were firstly described in a large family with generalized epilepsy and paroxysmal nonkinesigenic dyskinesia. Recently, homozygous KCNMA1 mutations were reported to cause a phenotype of cerebellar atrophy, developmental delay and seizures. CASE REPORT: Herein; we report a patient with a novel homozygous truncating mutation in KCNMA1 (p...

Autism spectrum disorders (ASD) are diagnosed based on the behavioral criteria of impaired social interaction, defective communication and repetitive behaviors. Psychiatric comorbidities, such as anxiety and intellectual disability, are commonly present in ASD. The BTBR T+Itpr3tf/J (BTBR) mice display a range of autistic phenotypes, yet whether this mouse model is appropriate to study psychiatric comorbidity in ASD remains unclear. We addressed this issue by subjecting the BTBR animals to three-chambered apparatus, open field, object attention test and elevated open platform...
