Layla is a 6.7-year-old girl diagnosed with attention-deficit/hyperactivity disorder (ADHD)-predominantly hyperactive/impulsive type-delayed adaptive skills, enuresis, unspecified malnutrition, and feeding difficulties. She presented to developmental-behavioral pediatrics (DBP) in January 2022 due to caregiver concerns for autism spectrum disorder (ASD).Layla lives in a polyamorous family with her biological mother and father, mother's partner whom Layla refers to as her uncle, and her 2 half-siblings. There is a maternal history of special education services, schizoaffective disorder, bipolar disorder, multiple sclerosis, Wolff-Parkinson-White syndrome, and ADHD...

The primary cilium is a hair-like organelle that hosts molecular machinery for various developmental and homeostatic signaling pathways. Its alteration can cause severe ciliopathies such as the Bardet-Biedl and Joubert syndromes, but is also linked to Alzheimer's disease, clinical depression, and autism spectrum disorder. These afflictions are caused by disturbances in a variety of genes but a common phenotype amongst them is cognitive impairment. Cilia-mediated neural function has generally been examined in relation to these diseases or other developmental defects, but the role of cilia in brain function and memory consolidation is unknown...

KEY CLINICAL MESSAGE: Foreign body ingestion is common in pediatric age group however can be found in any age group with intellectual disability and neurodevelopmental delay. There is usually a delay in presentation and interventions following foreign body ingestion in patients with neurodevelopmental delay, leading to increased morbidity, mortality, and complications owing to inability of such patients giving relevant history. Most ingested foreign bodies naturally pass through the digestive tract without untoward effects...

Autism spectrum disorder (ASD) is a neurodevelopmental condition frequently associated with structural cerebellar abnormalities. Whether cerebellar grey matter volumes (GMV) are linked to verbal impairments remains controversial. Here, the association between cerebellar GMV and verbal abilities in ASD was examined across the lifespan. Lobular segmentation of the cerebellum was performed on structural MRI scans from the ABIDE I dataset in male individuals with ASD (N=144, age: 8.5-64.0 years) and neurotypical controls (N=188; age: 8...

Sex-based differences in the prevalence of autism spectrum disorder (ASD) are well-documented, with a male-to-female ratio of approximately 4:1. The clinical presentation of the core symptoms of ASD can also vary between sexes. Previously, positron emission tomography (PET) studies have identified alterations in the in vivo levels of translocator protein (TSPO)-a mitochondrial protein-in primarily or only male adults with ASD, with our group reporting lower TSPO relative to whole brain mean in males with ASD...

Sleep difficulties can co-occur with autistic traits and have been frequently reported in children diagnosed with autism. Thus, sleep difficulties may impact neural development, cognition, and behavioural functioning in children with autism. Interventions, such as repetitive transcranial magnetic stimulation (rTMS), that target aberrant neural structures underpinning autistic traits and sleep difficulties in children could have beneficial effects. The rTMS effects on the pathophysiological pathways hypothesised to underpin autism and sleep difficulties are well-established in the literature; however, clinical evidence of its potential to improve sleep difficulties in children with autism is limited...

PURPOSE: Adolescents and adults with Down syndrome are noted to display symptoms and behaviors consistent with a diagnosis of Obsessive Compulsive Disorder. While evidenced-based interventions, including psychopharmacology and therapeutic interventions including exposure and response prevention, exist and effectively treat obsessive-compulsive symptoms in neurotypical populations, less is known about effective treatments for similar presentations in persons with Down syndrome. METHODS: A scoping rapid review was conducted in April 2023 to determine what treatments are being used to target obsessive-compulsive symptoms and related behaviors in adolescents and adults with Down syndrome, the quality of those treatments, and their alignment with current evidenced-based interventions...

BACKGROUNDS: Many autistic people in mental health are suicidal. This study evaluated the effectiveness of dialectical behavior therapy (DBT) v. treatment as usual (TAU) in reducing suicidal ideation and suicide attempts. METHODS: At six Dutch mental health centers, 123 outpatients (18-65 years) with DSM-5 diagnosed autism spectrum disorder (ASD) and suicidal behavior were randomly assigned to the DBT intervention group ( n = 63) or TAU control group ( n = 60). Assessments were conducted at baseline, post-treatment at 6 months and 12-month follow-up...

INTRODUCTION: Korean autistic persons who have endured an integrated secondary education system have been exposed to school bullying, causing trauma and stigma to them. It also blocks them from entering a tertiary education system and a decent work, resulting in a lower quality of life. However, research on how it affects autistic persons has not yet been conducted in Korea. METHODS: Fourteen adult autistic persons in the Republic of Korea participated in the semi-structured focused group interviews...

Nick is a 5-year-old boy who began displaying self-stimulating behaviors and decreased social interactions shortly before turning 3 years. At the age of 3.5 years, he was diagnosed with autism spectrum disorder by a local developmental-behavioral pediatrician. His parents recall that the physician described Nick to be "high functioning" and encouraged them to expect that he would attend college and live independently as an adult. Upon receiving the diagnosis, intervention was initiated using an applied behavioral analysis (ABA) approach...

This position paper explores the needs of rural families of children, adolescents, and adults with autism spectrum disorder (ASD) during the COVID-19 pandemic. Prior to COVID-19, literature portrays elevated stress in families of individuals with ASD and health and socioeconomic disparities for rural and underserved populations. These disparities were exacerbated due to COVID-19 and subsequent lockdowns and economic turmoil. Academic and adaptive skills training were particularly impacted due to school closures, with parents tasked with taking some responsibility for training these skills...

BACKGROUND AND METHODS: The aim of this systematic review was to synthesise research examining the relationship between autism and psychopathy to: (a) better understand the relationship between these two constructs, and (b) describe the clinical manifestation of the two when they co-occur. A systematic search of the literature returned 36 studies. RESULTS: Across all ages, autistic individuals and those with elevated autistic traits but no autistic diagnoses appeared to have increased callous and unemotional traits or psychopathy relative to the general population...

BACKGROUND: Inflammatory bowel diseases (IBDs) are incurable diseases that require lifelong access to health services. Accumulating evidence of inequalities in health care access, experience, and outcomes for individuals with IBD is apparent. This review aimed to describe the inequalities in healthcare access, experiences, and outcomes of care for adults with IBD, to identify research gaps, and to identify future research priorities in this area. METHODS: A scoping review was conducted to retrieve quantitative, qualitative, and mixed methods evidence from 3 databases (EMBASE, Medline, and CINAHL) published between January 1, 2000, and September 27, 2023...

The study of atypical language acquisition in children with, autism spectrum disorder (ASD) is crucial for both practical and theoretical reasons. Understanding the course of language development in ASD can inform potential interventions and treatments while shedding light on the necessary conditions for language development in typically developing children. This scientometric review aims to provide a comprehensive overview of the research landscape in this field, identifying trends, patterns, and knowledge gaps...

BACKGROUND: Many autistic people, particularly women, do not receive an autism diagnosis until adulthood, delaying their access to timely support and clinical care. One possible explanation is that autistic traits may initially be misinterpreted as symptoms of other psychiatric conditions, leading some individuals to experience misdiagnosis of other psychiatric conditions prior to their autism diagnosis. However, little is currently known about the frequency and nature of psychiatric misdiagnoses in autistic adults...

Oxytocin (OXT) modulates social behaviors. However, the administration of exogenous OXT in humans produces inconsistent behavioral changes, affecting future consideration of OXT as a treatment for autism and other disorders with social symptoms. Inter-individual variability in social functioning traits might play a key role in how OXT changes brain activity and, therefore, behavior. Here, we investigated if inter-individual variability might dictate how single-dose intranasal OXT administration (IN-OXT) changes spontaneous neural activity during the eyes-open resting state...

Altered nonverbal communication patterns especially with regard to gaze interactions are commonly reported for persons with autism spectrum disorder (ASD). In this study we investigate and differentiate for the first time the interplay of attention allocation, the establishment of shared focus (eye contact and joint attention) and the recognition of intentions in gaze interactions in adults with ASD compared to control persons. Participants interacted via gaze with a virtual character (VC), who they believed was controlled by another person...

In the last decades, growing caseness for Autism Spectrum Disorder (ASD) has been observed, owing to the diagnostic accretion of low-impairment forms, over and above other possible causes. Unrecognized ASD is likely to be mislabeled as a psychotic disorder (PD), as people in the spectrum may show 'pseudopsychotic' symptoms, resembling both negative and positive symptoms. On the other hand, PDs are likely to be overlooked when they arise in people with ASD, due to the 'diagnostic overshadowing' of new-onset conditions by lifelong core autistic symptoms...

INTRODUCTION: The aim of this study was to examine possible associations of social anxiety (SA) and speaking-related physiological reactivity with the frequencies of a) total disfluencies, b) typical disfluencies, and c) stuttering-like disfluencies, as well as d) stuttering-severity in autistic young adults and controls. METHODS: Thirty-two autistic young adults and 35 controls participated in this study. Participants were presented with video clips (viewing condition) and were then asked to talk about the videos (narrating condition)...

A core feature of autism is deficits in executive functioning (EF), including difficulty with planning, cognitive flexibility, and working memory. Despite a growing need for evidence-based assessments of EF for autism populations, statistical models of many commonly used measures of EF, including the Delis-Kaplan Executive Function System (D-KEFS), have not been investigated for a sample of autistic participants. The purpose of this study was to address a gap in the literature regarding the latent structure of the D-KEFS in a sample of autistic individuals...
