IntroductionDespite categorical differentiation, autistic and psychotic disorders are historically related diagnostic entities and there is still much controversy regarding their limits and developmental course. Particularly in children, the presence of idiosyncratic fears, difficulties in the social sphere and thought disorder are important factors in the differential diagnosis. There are some research-derived clinical constructs that operationalize symptomatology aiming to highlight the interfaces and the overlap between such disorders. Their clinical implications can be extremely relevant in the face of the limits of current nosology.ObjetivesTo phenomenologically describe differentiating parameters and high-risk clinical profiles for the development of psychosis in children with autism spectrum disorder.MethodsSelective review of the literature in PubMed (MEDLINE). Illustration with a clinical case vignette.ResultsThe clinical case reflects well the difficulties posed in the differential diagnosis due to the multiple interfaces between autism and psychosis. Constructs such as “multiple complex developmental disorder” or “multidimensionally impaired syndrome” allow a clearer and more practice-friendly characterization of such individuals.ConclusionThe constelation of symptoms identified in these criteria may become useful through the definition of subgroups of autism spectrum disorder individuals with complex psychopathology. Studies in this regard are still scarce, but the validation and reproduction of the positive results observed in the near future can help optimize the clinical approaches in these children.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Neurodevelopmental lifelong pathologies defined by problems with social interaction, communication capacity and presence of repetitive/stereotyped clusters of behavior and interests are grouped under the definition of autism spectrum disorder (ASD). ASD prevalence is still increasing, indicating the need to identify specific biomarkers and novel pharmacotherapies. Neuroinflammation and neuro-immune cross-talk dysregulation are specific hallmarks of ASD, offering the possibility of treating these disorders by stem cell therapy. Indeed, cellular strategies have been postulated, proposed and applied to ASD. However, less is known about the molecular action mechanisms of stem cells. As a possibility, the positive and restorative effects mediated by stem cells could be due to their paracrine activity, by which stem cells produce and release several ameliorative and anti-inflammatory molecules. Among the secreted complex tools, exosomes are sub-organelles, enriched by RNA and proteins, that provide cell-to-cell communication. Exosomes could be the mediators of many stem cell-associated therapeutic activities. This review article describes the potential role of exosomes in alleviating ASD symptoms.

IntroductionAutism spectrum disorder and early onset schizophrenia have many similar symptoms, however, these are different disorders. It is important to identify the main similarities\differences in the structure of cognitive impairment to define further assistance these children correctly. We distinguished two options for cognitive defect (total and partial) in children with schizophrenia.AimsComparison of cognitive functions at children with autism spectrum disorder and early onset schizophrenia.ObjectivesTwo groups with autism spectrum disorder (ASD1 – 22 patients of MHRC mean age 8.9; ASD2 – 27 pupils of special school mean age 7,4). Two groups with early onset schizophrenia (F20.8 – 16 patients of MHRC mean age 10,2; F21 – 18 patients of MHRC mean age 10.0).MethodsBattery of pathopsychological tests for assessing cognitive functions (memory, attention, thinking), test figures of Leeper for visual perception. Z-scales were used for estimation of cognitive deficit or defect.ResultsPatients demonstrate variety of cognitive functioning. Normal cognitive functioning: ASD1* – 22%, F20.8 – 18%, F21* – 50% (* – P ≤ 0.05); partial cognitive defect: ASD1 – 27%, F20.8 – 18%, F21 – 22%; total cognitive defect: ASD1** – 50%, F20.8 – 64%, F21** – 27% (** – P ≤ 0.01). ASD1 and F20 were the worth in thinking. Children ASD1 and ASD2 demonstrate similar success in recognizing Leeper's figures.ConclusionsThere are some common features of cognitive development in children with severe forms of ASD and early onset schizophrenia, first of all in thinking.No significant differences obtained between severe – mild forms of autistic disorders in visual perception (ASD1 and ASD2).Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionAn overlap between autism spectrum disorder (ASD), in particular Asperger Syndrome (AS), and high intellectual potential (HIP–Total IQ > 2 SD) is often discussed.ObjectivesExplore differences between homogeneous and heterogeneous Wisc-profiles among HIP children, and between HIP and ASD children, on cognitive and clinical assessments.MethodsForty-nine participants (mean age 11.2 years) were divided in 4 groups: High Functioning Autism (HFA), AS, Homogenous HIP and Heterogeneous HIP. Data of WISC-IV and questionnaires – Autism Quotient (AQ), Empathy Quotient (EQ), Systemizing Quotient (SQ), Children's Communication Checklist (CCC) – were compared.(Preliminary) ResultsOn the WISC-IV, the Z scores curves follow similar trajectories but highlight quantitative differences between AS and heterogeneous HIP: verbal comprehension is the highest index (+1,6 SD in AS; +3,1 SD in heterogeneous HIP) followed by perceptual reasoning, working memory, and processing speed indexes (–1,2 SD in AS; +0,5 SD in heterogeneous HIP), respectively. The questionnaires show that scores of Homogenous HIP children are all in the average. Heterogeneous HIP children score 2,1 SD above average on the AQ (+1,6 SD on “Social Skills” and +1,3 SD on “Local Detail” subscales), whereas ASD children score 4 SD above average on the AQ. In addition, heterogeneous HIP children show pragmatic difficulties (–2,4 SD on the CCC, with a peak on “Area of Interest” subscale), also present in ASD children (–4 SD).ConclusionsAS and heterogeneous HIP children show similar cognitive profiles on the WISC-IV. Furthermore, heterogeneous HIP children exhibit high scores on the AQ and have pragmatic difficulties.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Social Communicative

Infant social-communicative behavior, such as gaze to the face of an interactive partner, is an important early developmental skill. Children with autism spectrum disorder exhibit atypicalities in social-communicative behavior, including gaze and eye contact. Behavioral differences in infancy may serve as early markers of autism spectrum disorder and help identify individuals at highest risk for developing the disorder. Researchers often assess social-communicative behavior in a single interactive context, such as during assessment with an unfamiliar examiner or play with a parent. Understanding whether infant behavior is consistent across such contexts is important for evaluating the validity of experimental paradigms and the generalizability of findings from one interactive context/partner to another. We examined infant gaze to the face of a social partner at 6, 9, and 12 months of age in infants who were later diagnosed with autism spectrum disorder, as well as low- and high-risk infants without autism spectrum disorder outcomes, across two interactive contexts: structured testing with an unfamiliar examiner and semi-structured play with a parent. By 9 months, infant gaze behavior was significantly associated between the two contexts. By 12 months, infants without autism spectrum disorder outcomes exhibited higher mean rates of gaze to faces during parent–child play than Mullen testing, while the gaze behavior of the autism spectrum disorder group did not differ by context—suggesting that infants developing autism spectrum disorder may be less sensitive to context or interactive partner. Findings support the validity of assessing infant social-communicative behavior during structured laboratory settings and suggest that infant behavior exhibits consistency across settings and interactive partners.

Abstract Facial movements of others during verbal and social interaction are often too rapid to be faced and/or processed in time by numerous children and adults with autism spectrum disorder (ASD), which could contribute to their face-to-face interaction peculiarities. We wish here to measure the effect of reducing the speed of one's facial dynamics on the visual exploration of the face by children with ASD. Twenty-three children with ASD and 29 typically-developing control children matched for chronological age passively viewed a video of a speaker telling a story at various velocities, i.e., a real-time speed and two slowed-down speeds. The visual scene was divided into four areas of interest (AOI): face, mouth, eyes, and outside the face. With an eye-tracking system, we measured the percentage of total fixation duration per AOI and the number and mean duration of the visual fixations made on each AOI. In children with ASD, the mean duration of visual fixations on the mouth region, which correlated with their verbal level, increased at slowed-down velocity compared with the real-time one, a finding which parallels a result also found in the control children. These findings strengthen the therapeutic potential of slowness for enhancing verbal and language abilities in children with ASD.

In this study, children with learning disability (LD) were compared with children with autism spectrum disorder(ASD) in terms of identifying emotions from photographs with certain face and body expressions. The sampleconsisted of a total of 82 children aged 7-19 years living in Izmir in Turkey. A total of 6 separate sets of slides,consisting of black and white photographs, were used to assess participants’ ability to identify feelings – 3 sets forfacial expressions, and 3 sets for body language. There were 20 photographs on the face slides and 38 photographson the body language slides. The results of the nonparametric Mann Whitney-U test showed no significant differencebetween the total scores that children received from each of the face and body language slide sets. It was observedthat the children with LD usually looked at the whole photo, while the children with ASD focused especially aroundthe mouth to describe feelings. The results that were obtained were discussed in the context of the literature, andsuggestions were presented.

And Behavior

Early diagnosis of autism spectrum disorder (ASD) has focused on differentiating children with ASD from neurotypical children. However, many children presenting with concern for ASD are ultimately diagnosed with language disorder (LD). This study aimed to identify differences in parent-rated development and behavior among children ages 2 to 5 years presenting with concern for ASD who were diagnosed with either ASD or LD. Children with ASD were rated as more socially withdrawn and more delayed in social development and self-help skills than those with LD. Parent-rated developmental delays were positively correlated with scores on an autism screening measure and with social withdrawal and pervasive developmental problems among children with ASD. Among those with LD, parent-rated social and self-help development were positively correlated with social withdrawal and attention problems. Thus, parent ratings of social withdrawal and development of social and self-help skills may facilitate differential diagnosis of ASD and LD in children ages 2 to 5 years.
