Neural Correlates of Duration Discrimination in Young Adults with Autism Spectrum Disorder, Attention-Deficit/Hyperactivity Disorder and Their Comorbid Presentation

Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) often co-occur and share neurocognitive deficits. One such shared impairment is in duration discrimination. However, no studies using functional magnetic resonance imaging (fMRI) have investigated whether these duration discrimination deficits are underpinned by the same or different underlying neurofunctional processes. In this study, we used fMRI to compare the neurofunctional correlates of duration discrimination between young adult males with ASD (n = 23), ADHD (n = 25), the comorbid condition of ASD+ADHD (n = 24), and typical development (TD, n = 26) using both region of interest (ROI) and whole brain analyses. Both the ROI and the whole-brain analyses showed that the comorbid ASD+ADHD group compared to controls, and for the ROI analysis relative to the other patient groups, had significant under-activation in right inferior frontal cortex (IFG) a key region for duration discrimination that is typically under-activated in boys with ADHD. The findings show that in young adult males with pure ASD, pure ADHD and comorbid ASD+ADHD with no intellectual disability, only the comorbid group demonstrates neurofunctional deficits in a typical duration discrimination region

Improved Attitudes to Psychiatry: A Global Mental Health Peer-to-Peer E-Learning Partnership

Objective: Health links aim to strengthen healthcare systems in low and middle-income countries through mutual exchange of skills, knowledge, and experience. However, student participation remains limited despite growing educational emphasis upon global health. Medical students continue to report negative attitudes to psychiatry in high-income countries, and in Somaliland, the lack of public sector psychiatrists limits medical students' awareness of mental healthcare. The authors describe the design, implementation, and mixed-methods analysis of a peer-to-peer psychiatry e-learning partnership between UK and Somaliland students arising from a global mental health link between the two countries. Methods: Medical students at King's College London and Hargeisa and Amoud universities, Somaliland, were grouped into 24 pairs. Participants aimed to complete ten fortnightly meetings to discuss psychiatry topics via the website MedicineAfrica. Students completed initial and final evaluations including Attitudes toward Psychiatry (ATP-30) questions, a stigma questionnaire, and brief evaluations after each meeting. Results: Quantitative findings demonstrated that enjoyment, interest, and academic helpfulness were rated highly by students in Somaliland and moderately by students in the UK. Somaliland students' attitudes to psychiatry were significantly more positive post-participation, whereas UK students' attitudes remained stable. Qualitative findings identified more gains in factual knowledge for Somaliland students, whereas UK students reported more cross-cultural learning. Reasons for non-completion and student-suggested improvements emphasized the need to ensure commitment to the program by participants. Conclusions: This partnership encouraged students to consider global mental health outside the standard medical education environment, through an e-learning format solely utilizing existing resources. This new approach demonstrates potential benefits to students in contrasting locations of brief, focused online peer-to-peer education partnerships, expanding the scope of health links to the medical professionals of the futur

ADHD Remote Technology study of cardiometabolic risk factors and medication adherence (ART-CARMA): a multi-centre prospective cohort study protocol.

BACKGROUND: Emerging evidence points at substantial comorbidity between adult attention deficit hyperactivity disorder (ADHD) and cardiometabolic diseases, but our understanding of the comorbidity and how to manage cardiometabolic disease in adults with ADHD is limited. The ADHD Remote Technology study of cardiometabolic risk factors and medication adherence (ART-CARMA) project uses remote measurement technology to obtain real-world data from daily life to assess the extent to which ADHD medication treatment and physical activity, individually and jointly, may influence cardiometabolic risks in adults with ADHD. Our second main aim is to obtain valuable real-world data on adherence to pharmacological treatment and its predictors and correlates during daily life from adults with ADHD. METHODS: ART-CARMA is a multi-site prospective cohort study within the EU-funded collaboration 'TIMESPAN' (Management of chronic cardiometabolic disease and treatment discontinuity in adult ADHD patients) that will recruit 300 adults from adult ADHD waiting lists. The participants will be monitored remotely over a period of 12 months that starts from pre-treatment initiation. Passive monitoring, which involves the participants wearing a wrist-worn device (EmbracePlus) and downloading the RADAR-base Passive App and the Empatica Care App on their smartphone, provides ongoing data collection on a wide range of variables, such as physical activity, sleep, pulse rate (PR) and pulse rate variability (PRV), systolic peaks, electrodermal activity (EDA), oxygen saturation (SpO2), peripheral temperature, smartphone usage including social connectivity, and the environment (e.g. ambient noise, light levels, relative location). By combining data across these variables measured, processes such as physical activity, sleep, autonomic arousal, and indicators of cardiovascular health can be captured. Active remote monitoring involves the participant completing tasks using a smartphone app (such as completing clinical questionnaires or speech tasks), measuring their blood pressure and weight, or using a PC/laptop (cognitive tasks). The ART system is built on the RADAR-base mobile-health platform. DISCUSSION: The long-term goal is to use these data to improve the management of cardiometabolic disease in adults with ADHD, and to improve ADHD medication treatment adherence and the personalisation of treatment

Immune signatures and disorder-specific patterns in a cross-disorder gene expression analysis

Background Recent studies point to overlap between neuropsychiatric disorders in symptomatology and genetic aetiology. Aims To systematically investigate genomics overlap between childhood and adult attention-deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD) and major depressive disorder (MDD). Method Analysis of whole-genome blood gene expression and genetic risk scores of 318 individuals. Participants included individuals affected with adult ADHD (n = 93), childhood ADHD (n = 17), MDD (n = 63), ASD (n = 51), childhood dual diagnosis of ADHD–ASD (n = 16) and healthy controls (n = 78). Results Weighted gene co-expression analysis results reveal disorder-specific signatures for childhood ADHD and MDD, and also highlight two immune-related gene co-expression modules correlating inversely with MDD and adult ADHD disease status. We find no significant relationship between polygenic risk scores and gene expression signatures. Conclusions Our results reveal disorder overlap and specificity at the genetic and gene expression level. They suggest new pathways contributing to distinct pathophysiology in psychiatric disorders and shed light on potential shared genomic risk factors

Adults with autism spectrum disorder and the criminal justice system:An investigation of prevalence of contact with the criminal justice system, risk factors and sex differences in a specialist assessment service

The behavioural and cognitive difficulties of some adults with autism spectrum disorder (ASD) may increase their risk of contact with the criminal justice system (CJS) as a potential suspect. There has been limited investigation of ASD and offending and available evidence is mixed. A retrospective review was completed of medical records of 1570 adults (17–75 years old) who were referred for an ASD assessment over a 17-year period (April 2003 to February 2020). Of the adults diagnosed with ASD, 23% had previous contact with the CJS. Being male or diagnosed with co-occurring attention-deficit hyperactivity disorder (ADHD) and/or psychotic disorder were risk factors for CJS contact. However, the rates of contact with the CJS or for specific offences in the ASD group were never higher than adults referred to our service but not diagnosed with ASD. We did not include a general population comparison group, therefore cannot say how rates of CJS contact in ASD compare with the general population. Further health services research for adults with ASD is warranted, as modifying the treatable risk factors (i.e. ADHD) could reduce contact with the CJS. In addition, joint working between CJS and mental health services could reduce the risk of adults with ASD having CJS contact. LAY ABSTRACT: There has been growing interest in offending and contact with the criminal justice system (CJS) by people with autism spectrum disorder (ASD). However, it is not clear whether people with ASD offend more than those without ASD. Studies have started to look at whether there are particular offences people with ASD are more likely to commit and whether there are any factors that can affect whether someone comes into contact with the CJS as a potential suspect. This study looked at the patients who attended an ASD diagnostic service over a 17-year period to see the rate of contact with the CJS of those who were diagnosed with ASD and whether there were any particular factors that might increase the risk of CJS contact. Nearly a quarter of the ASD group had some contact with the CJS as a potential suspect. Factors that seemed to increase whether someone with ASD was more likely to have contact with the CJS were being male, being diagnosed with ADHD, and being diagnosed with psychosis. This study is one of the largest studies to investigate the rate of CJS contact as a potential suspect in a sample of adults with ASD in an attempt to give a clearer picture of what might influence someone with ASD to engage in offending behaviour in order to try to see what mental health services can offer to reduce the likelihood of someone with ASD coming into contact with the CJS, for example, treatment for another condition or support
