Carruthers S, Kinnaird E, Rudra A, Smith P, Allison C, Auyeung B, Chakrabarti B, Wakabayashi A, Baron-Cohen S, Bakolis I, Hoekstra RAet al., 2018, A cross-cultural study of autistic traits across India, Japan and the UK., Mol Autism, Vol: 9

Background: There is a global need for brief screening instruments that can identify key indicators for autism to support frontline professionals in their referral decision-making. Although a universal set of conditions, there may be subtle differences in expression, identification and reporting of autistic traits across cultures. In order to assess the potential for any measure for cross-cultural screening use, it is important to understand the relative performance of such measures in different cultures. Our study aimed to identify the items on the Autism Spectrum Quotient (AQ)-Child that are most predictive of an autism diagnosis among children aged 4-9 years across samples from India, Japan and the UK. Methods: We analysed parent-reported AQ-Child data from India (73 children with an autism diagnosis and 81 neurotypical children), Japan (116 children with autism and 190 neurotypical children) and the UK (488 children with autism and 532 neurotypical children). None of the children had a reported existing diagnosis of intellectual disability. Discrimination indices (DI) and positive predictive values (PPV) were used to identify the most predictive items in each country. Results: Sixteen items in the Indian sample, 15 items in the Japanese sample and 28 items in the UK sample demonstrated excellent discriminatory power (DI ≥ 0.5 and PPV ≥ 0.7), suggesting these items represent the strongest indicators for predicting an autism diagnosis within these countries. Across cultures, good performing items were largely overlapping, with five key indicator items appearing across all three countries (can easily keep track of several different people's conversations, enjoys social chit-chat, knows how to tell if someone listening to him/her is getting bored, good at social chit-chat, finds it difficult to work out people's intentions). Four items indicated potential cultural differences. One item was highly discriminative in Japan but poorly discrimina

We previously provided initial evidence for cognitive and event-related potential markers of persistence/remission of attention-deficit/hyperactivity disorder (ADHD) from childhood to adolescence and adulthood. In this follow-up study, using a novel brain-network connectivity approach, we aimed to examine whether functional connectivity reflects a marker of ADHD remission, or an enduring deficit unrelated to ADHD outcome. High-density EEG was recorded in 110 adolescents and young adults with childhood ADHD (87 persisters, 23 remitters) and 169 typically-developing individuals during an arrow-flanker task, eliciting cognitive control. Functional connectivity was quantified with network-based graph-theory metrics before target onset (pre-stimulus), during target processing (post-stimulus) and in the degree of change between pre-stimulus/post-stimulus. ADHD outcome was examined with parent-reported symptoms and impairment using both a categorical (DSM-IV) and a dimensional approach. Graph-theory measures converged in indicating that, compared to controls, ADHD persisters showed increased connectivity in pre-stimulus theta, alpha and beta and in post-stimulus beta (all p<.01), and reduced pre-stimulus/post-stimulus change in theta connectivity (p<.01). In the majority of indices showing ADHD persister-control differences, ADHD remitters differed from controls (all p<.05), but not from persisters. Similarly, connectivity measures were not associated with continuous outcome measures of ADHD symptoms and impairment in participants with childhood ADHD. These findings indicate that adolescents and young adults with persistent and remitted ADHD share atypical over-connectivity profiles and reduced ability to modulate connectivity patterns with task demands, compared to controls. Brain connectivity impairments may represent enduring deficits in individuals with childhood ADHD irrespective of diagnostic status in adolescence/young adulthood.

© 2016 Informa UK Limited, trading as Taylor & Francis Group. This study aimed to examine the pathways to care and the duration of untreated psychosis (DUP) in first-episode psychosis patients in Italy. Sociodemographic and clinical characteristics of patients were collected using an ad-hoc schedule. Pathways to care of patients were evaluated by the Nottingham Onset Schedule, administered to patients, key-relatives and key-workers. Forty patients from the Department of Psychiatry of University of Naples were recruited. Mean duration of untreated illness (DUI) was 135.9±145.9 weeks, main DUP was 27.4±26.7 weeks. First help-seeking contact, often mediated by close relatives, took place after 21.6±43.8 weeks from symptoms onset and was with general practitioners, neurologists or psychologists. Only 25% immediately referred to psychiatrists. Patients had 1.8±0.8 contacts with non-psychiatric medical professionals before referring to the mental health service, and the mean time between first contact and adequate psychiatric treatments (referral delay) was 26.6±64.1 weeks. The DUI and DUP was longer in patients with less education (p <.05) and in those with an insidious onset of symptoms (p <.01). Targeted interventions and information campaigns on at-risk populations, such as young people and their relatives, could reduce the DUP, thus improving the long-term outcome of psychotic disorders.
