In vivo translocator protein in females with autism spectrum disorder: a pilot study.

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. However, whether in vivo TSPO levels are altered in females with ASD, specifically, is unknown. This is the first pilot study to measure in vivo TSPO in the brain in adult females with ASD using [11C]PBR28 PET-magnetic resonance imaging (MRI). Twelve adult females with ASD and 10 age- and TSPO genotype-matched controls (CON) completed one or two [11C]PBR28 PET-MRI scans. Females with ASD exhibited elevated [11C]PBR28 standardized uptake value ratio (SUVR) in the midcingulate cortex and splenium of the corpus callosum compared to CON. No brain area showed lower [11C]PBR28 SUVR in females with ASD compared to CON. Test-retest over several months showed stable [11C]PBR28 SUVR across time in both groups. Elevated regional [11C]PBR28 SUVR in females with ASD stand in stark contrast to our previous findings of lower regional [11C]PBR28 SUVR in males with ASD. Preliminary evidence of regionally elevated mitochondrial protein TSPO relative to whole brain mean in ASD females may reflect neuroimmuno-metabolic alterations specific to females with ASD.

Clinical Challenges and Solutions in Adapting Cognitive Behavioral Therapy for Anxiety in Adults With Intellectual Disability.

While cognitive behavioral therapy (CBT) is a first-line treatment for anxiety, it is not typically offered to those with intellectual disability (ID). In this article, we provide a historical perspective on the treatment of mental health concerns in adults with ID, describe an adapted CBT treatment for anxiety in adults with Williams syndrome (WS) and mild to moderate ID, and discuss general modifications to CBT for adults with ID. Strategies used to successfully adapt CBT for adults with WS that may generalize for adults with ID more broadly include: (a) using child-based CBT manuals as a framework; (b) involving a caregiver as a therapy partner; (c) incorporating a high level of repetition; (d) simplifying language; (e) slowing the pace of instruction; and (f) incorporating specific examples and adaptations for WS.

Mobile device applications and treatment of autism spectrum disorder: a systematic review and meta-analysis of effectiveness.

OBJECTIVE: The current study was performed to assess the evidence for effects of therapeutic intervention with mobile device applications (apps) for individuals with autism spectrum disorder (ASD). DESIGN: The main methodology of the current study was systematic review with meta-analysis. SETTING: Only randomised controlled trials (RCTs) for mobile device apps for individuals with ASD were considered for review in the current study. PATIENTS: The target population was individuals clinically diagnosed with ASD. INTERVENTIONS: Applications that are operable on a smart (mobile) device and interactive with users. MAIN OUTCOME MEASURES: The main outcomes were based on standardised mean differences in pretrial and post-trial scales in each control and intervention group. RESULTS: Out of a total of 1100 studies (after duplicate removal), 7 RCTs were selected for final analysis. Of the seven studies, two RCTs were further analysed for effects based on the visual and fine motor subscales of the Mullen Scales of Early Learning, which favoured the intervention groups (standardised mean difference (SMD)=0.41, 95% CI 0.03 to 0.80; SMD=0.41, 95% CI 0.03 to 0.80), without either having any heterogeneity (p>0.1) or publication bias. CONCLUSIONS: Although it is still early to draw a conclusion, available studies are showing promise for use of mobile device apps for treatment of individuals with ASD. More well-designed and large-scale studies focused on improving behavioural symptoms of ASD are warranted. PROSPERO REGISTRATION NUMBER: CRD42019128362.

Exploring the use of Sidekicks! For children with autism spectrum disorder (ASD).

Clinicians and educators are increasingly using technology within the context of existing therapies and teaching methodologies. The growing use of mobile clinical tools is particularly exciting for individuals with autism spectrum disorder (ASD), as technologically based interventions have been shown to be both efficacious (to target academics, adaptive behavior, disruptive behavior, etc.) and accepted in this population (Odom et al., 2015). In addition, these tools have the potential to address two significant impediments in ASD intervention, the anxiety and/or skill deficits often associated with face-to-face interactions and skill generalization outside of the therapy office (Wieckowski & White, 2017). In other words, the use of technology may serve as an important preliminary or prerequisite step for face-to-face therapeutic progress. The purpose of this paper is to present a new, interactive clinical app that explicitly utilizes an individual's restricted interests to teach skills and improve communication. The paper will briefly review the ways in which individuals with ASD may be good candidates for technological-based interventions, explore the current role of technology in existing evidence-based therapies, and discuss the use of a new technology, Sidekicks!, that has been developed for this population. A case example will then illustrate the use of Sidekicks! and its anticipated functionality across several public service settings, including hospitals, outpatient clinics, and school systems, thereby coordinating the intervention efforts of various professionals involved in the treatment of children with ASD. Finally, limitations of the app (and of technology more generally) and the need for future research will be discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
