BACKGROUND: Midkine (MK) is a heparin binding growth factor and is involved in neurogenesis, neural development and neuroprotection. Additionally MK may contribute to cancer development and pathogenesis of neurodegenerative disorders and schizophrenia. Considering these effects of midkine, this study researched whether MK is involved in Autism spectrum disorders (ASD) pathogenesis. METHODS: We evaluated serum MK levels of 38 patients with ASD and 32 healthy control group...

Autism Diagnostic Observation Schedule (ADOS) is one of the most popular instruments used world-widely in the diagnosis of autism spectrum disorders (ASD). Unfortunately, there are only a few studies of the psychometric properties of non-English language versions of this instrument and none of the adaptation of its second edition (ADOS-2). The objective of this study was to verify the psychometric properties of the Polish version of the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2-PL). The authors recruited 401 participants: 193 with ASDs (ASD group) and 78 with non-spectrum disorders, plus 130 typically developing participants (control group)...

Failure to appropriately develop multisensory integration (MSI) of audiovisual speech may affect a child's ability to attain optimal communication. Studies have shown protracted development of MSI into late-childhood and identified deficits in MSI in children with an autism spectrum disorder (ASD). Currently, the neural basis of acquisition of this ability is not well understood. Here, we developed a computational model informed by neurophysiology to analyze possible mechanisms underlying MSI maturation, and its delayed development in ASD...

Autism spectrum disorder is the fastest growing developmental disability in the United States. As such, there is an unprecedented need for research examining factors contributing to the health disparities in this population. This research suggests a relationship between the levels of physical activity and health outcomes. In fact, excessive sedentary behavior during early childhood is associated with a number of negative health outcomes. A total of 53 children participated in this study, including typically developing children (mean age = 42...

Background: Autism spectrum disorder (ASD), a developmental disorder of early childhood onset, affects males four times more frequently than females, suggesting a role for the sex chromosomes. In this study, we describe a family with ASD in which a predicted pathogenic nonsense mutation in the X-chromosome gene RAB39B segregates with ASD phenotype. Methods: Clinical phenotyping, microarray, and whole genome sequencing (WGS) were performed on the five members of this family...

Individuals with 22q11.2 microdeletion syndrome (22q11.2 DS) show cognitive and behavioral dysfunctions, developmental delays in childhood and risk of developing schizophrenia and autism. Despite extensive previous studies in adult animal models, a possible embryonic root of this syndrome has not been determined. Here, in neurons from a 22q11.2 DS mouse model (Lgdel (+/-)), we found embryonic-premature alterations in the neuronal chloride cotransporters indicated by dysregulated NKCC1 and KCC2 protein expression levels...

Polybrominated diphenyl ethers (PBDEs) are recognized neurotoxicants, but the extent to which PBDEs influence various domains of behavior in children is not fully understood. As such, we reviewed epidemiologic studies published to date to provide an overview of the current state of knowledge on PBDEs' potential role in behavioral development. We identified 19 epidemiologic studies reporting on associations of prenatal and childhood concentrations of PBDEs with behaviors assessed in children from 1 to 12years, including executive function, attention, externalizing and internalizing behaviors, adaptive skills, and social behaviors/Autism Spectrum Disorder (ASD)...

Autism and Autism Spectrum Disorder (ASD) cover a large variety of clinical profiles which share two main dimensions: social and communication impairment and repetitive behaviors or restricted interests, which are present during childhood. There is now no doubt that genetic factors are a major component in the etiology of autism but precise physiopathological pathways are still being investigated. Furthermore, developmental trajectories combined with compensatory mechanisms will lead to various clinical and neurophysiological profiles which together constitute this Autism Spectrum Disorder...

Almost all states have insurance coverage mandates for childhood autism spectrum disorder treatment, yet little is known about how mandates affect spending and service use. We evaluated a 2011 Kansas law mandating comprehensive coverage of autism spectrum disorder treatments in the State Employee Health Plan. Data were extracted from the Kansas All-Payer Claims Database from 2009 to 2013 for enrollees of State Employee Health Plan and private health plans. The sample included children aged 0-18 years with >2 claims with an autism spectrum disorder diagnosis insured through State Employee Health Plan or a comparison group enrolled through private health plans...

Acknowledgment of the gut microbiome as a vital asset to health has led to multiple studies attempting to elucidate its mechanisms of action. During the first year of life, many factors can cause fluctuation in the developing gut microbiome. Host genetics, maternal health status, mode of delivery, gestational age, feeding regime, and perinatal antibiotic usage, are known factors which can influence the development of the infant gut microbiome. Thus, the microbiome of vaginally born, exclusively breastfed infants at term, with no previous exposure to antibiotics, either directly or indirectly from the mother, is to be considered the "gold standard...

BACKGROUND: Recent analyses of trait-disorder overlap suggest that psychiatric dimensions may relate to distinct sets of genes that exert maximum influence during different periods of development. This includes analyses of social communication difficulties that share, depending on their developmental stage, stronger genetic links with either autism spectrum disorder or schizophrenia. We developed a multivariate analysis framework in unrelated individuals to model directly the developmental profile of genetic influences contributing to complex traits, such as social communication difficulties, during an approximately 10-year period spanning childhood and adolescence...

We examined phenotypes of autism spectrum disorder (ASD) based on trajectories of intellectual development from early (ages 2-3 ½) to middle (ages 5-8) childhood in a recent clinically ascertained cohort. Participants included 102 children (82 males) initially diagnosed with ASD from the Autism Phenome Project longitudinal sample. Latent class growth analysis was used to identify distinct IQ trajectories. Baseline and developmental course differences among groups were assessed using univariate techniques and repeated measures regression models, respectively...

OBJECTIVE: To investigate the clinical efficacy of transcutaneous electrical acupoint stimulation (TEAS) in treating children with autism spectrum disorders. METHODS: Forty-one autistic children receiving rehabilitation training were randomized into TEAS (n=21) and control (n=20) groups. The control group only received rehabilitation training. The TEAS group received both rehabilitation training and TEAS treatment[2 Hz/15 Hz alternating frequencies through two pairs of skin electrodes placed at Hegu (LI 4)-Neiguan (PC 6) on unilateral side, and Zusanli (ST 36)-Sanyinjiao (SP 6) on the contralateral side]...

Extensive studies have indicated brain function connectivity abnormalities in autism spectrum disorder (ASD). However, there is a lack of longitudinal or cross-sectional research focused on tracking age-related developmental trends of autistic children at an early stage of brain development or based on a relatively large sample. The present study examined brain network changes in a total of 186 children both with and without ASD from 3 to 11 years, an early and key development period when significant changes are expected...

Autism spectrum disorder (ASD) is the fastest growing group of neurodevelopmental disorders in childhood. Earlier detection means an increased need for early intervention and other educational services. This study examined what services a sample of young children with ASD received, what variables predicted service utilization, and how satisfied parents were with the services. Sixty children (2-7 years) and their families from the Northwestern United States participated in the study. Results suggest that, on average, children received 13 hours of educational and therapeutic services per week, with younger children receiving fewer services than older children...

AIM: To evaluate clinical and neurophysiological changes in children with different variants of autism spectrum disorders during treatment with cerebrolysin. MATERIAL AND METHODS: Forty-three children with autism spectrum disorders, aged 4-6 years, were included in the study. To assess the degree of autism, the quantitative scale of assessing the severity of child autism CARS ('Childhood Autism Rating Scale') was used. A comparative analysis of the clinical picture of disease and data of the electroencephalographic examination in endogenous and exogenous (organic) variant of autism was made...

BACKGROUND: Inhibitory control deficits are common in autism spectrum disorder (ASD) and associated with more severe repetitive behaviors. Inhibitory control deficits may reflect slower execution of stopping processes, or a reduced ability to delay the onset of behavioral responses in contexts of uncertainty. Previous studies have documented relatively spared stopping processes in ASD, but whether inhibitory control deficits in ASD reflect failures to delay response onset has not been systematically assessed...

The development of executive function (EF) in autism spectrum disorder (ASD) has only been investigated using "cool"-cognitive-EF tasks. Little is known about the development of "hot"-affective-EF and whether it follows a similar developmental pathway. This study employed a cross-sectional developmental trajectories approach to examine the developmental changes in cool (working memory, inhibition, and planning) and hot EF (delay discounting and affective decision-making) of ASD participants (n = 79) and controls (n = 91) relative to age and IQ, shedding more light on the hot-cool EF organization...
