Despite the sharp increase in the number of studies focused on late diagnosis over the last 15 years, there remains no consensus as to what constitutes a late diagnosis of autism, with cutoffs ranging from infancy to middle adulthood. This preregistered systematic review evaluated (a) the field's current quantification of late diagnosis in autism, (b) how the threshold for late diagnosis varies as a function of demographic and population factors, and (c) trends over time. Of the 11,697 records retrieved, <i>N</i> = 420 articles met inclusion criteria and were extracted. Articles spanned 35 years (1989–2024) and included participants from every continent except Antarctica. Only 34.7% of included studies provided a clear threshold for “late diagnosis” (<i>n</i> = 146/420). Late diagnosis cutoffs averaged 11.53 years (range = 2–55 years; median = 6.5 years) with a bimodal distribution (3 and 18 years). The threshold for late diagnosis varied by participant location, <i>F</i>(5,140) = 10.4, <i>p</i> &lt; 0.0001, and sample age, <i>F</i>(5,140) = 20.1, <i>p</i> &lt; 0.0001. Several key rationales for age determinations emerged, including access to services, considerations for adult diagnoses, and data driven approaches. What authors consider to be a “late” diagnosis of autism varies greatly according to research context. Justifications for a specific late-diagnosis age cutoff varied, underscoring the need for authors to contextualize their conceptualizations.</p>","PeriodicalId":131,"journal":{"name":"Autism Research","volume":"18 1","pages":"22-36"},"PeriodicalIF":5.3,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142696065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing research on SIB in autism spectrum disorder (ASD) has been limited by significant methodological and conceptual inconsistencies. Thus, the current study leveraged item-level data capturing the severity of unique SIB topographies to further understanding of factors associated with distinct SIB in a sample of 582 autistic youth (<i>M</i>_age = 12.12, <i>SD</i>_age = 3.68; range: 3–19 years; 13% females). Results suggest variation in severity endorsements for specific SIB topographies amongst autistic youth, such that 30%–50% of caregivers endorsed slight to very serious concern regarding the SIB topographies of bites nails/skin/fingers, scratches self, hits head/face/neck, bangs head against things, and picks skin. Generalized additive models demonstrated distinct patterns of associations between each SIB topography and dysregulation, sensory hypersensitivity, age, sex, IQ, and language level. Findings underscore the importance of exploring SIB as a multifaceted construct to capture unique correlates of distinct SIB that vary in severity and functional impact, which is critical for the development of effective interventions.

Infants at HL for autism and typically developing (TD) infants aged within 24 months were tested. In the experiment, participants' gaze was initially guided to the eye or mouth region immediately before the onset of the face. Latency to orient away from the guided regions, latency to orient to the eyes, and the location of the secondary fixation following the onset of the face were measured. The results showed that: (1) The HL infants looked less at eyes than TD infants; (2) Compared with TD infants, HL infants oriented towards eyes more slowly after being guided to the mouth; (3) After being guided to the eyes, HL infants' secondary fixation fell less in the eye region, and their latency to orient away from the eyes was also tended to be shorter. These results suggest that reduced eye-looking time was presented in HL infants, which was further explained by both eye avoidance and indifference to the eyes.

To our knowledge, there are currently no established imitation assessments that have been validated for use in virtual contexts. This study was designed to examine the reliability and validity of two caregiver-implemented imitation measures delivered with support from a remote virtual assessor. Study participants (177 caregiver-child dyads) were enrolled in a large, multisite study that is examining the effectiveness of a caregiver-implemented intervention delivered through the Part C early intervention (EI) system across four states. Results indicate that the assessments can be administered remotely with strong fidelity, internal reliability, predictive validity, discriminant validity, convergent validity, and sensitivity to change. Stability over time was adequate. These findings suggest that imitation skills can be measured effectively using a remote caregiver-implemented assessment, which provides greater opportunity for virtual clinical trials targeting social communication in young children.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Clinical Trial Registration</h3>\u0000 \u0000 <p>The trial protocol was registered at ClinicalTrials.gov (NCT05114538).</p>\u0000 </section>\u0000 </div>","PeriodicalId":131,"journal":{"name":"Autism Research","volume":"18 1","pages":"122-132"},"PeriodicalIF":5.3,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11782728/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142683368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A battery of tasks measuring mentalising and EF (working memory, inhibition, shifting, generativity) was also administered. Relationships between scores on cognitive measures and narrative performance were investigated using hierarchical linear regression analyses. Mentalising scores were found to significantly predict narrative performance across all outcome measures and were a stronger predictor than diagnostic group.

Computerized search of the forensic records of 11,853 adults assessed between January 1, 2012, and January 1, 2022, for criminal responsibility by the Turkish Council of Forensic Medicine found 74 adults diagnosed with ASD; they ranged in age from 18 to 40.

The ASD group was younger, more likely to be unemployed and not living on their own. The ASD group was more likely to have co-morbid intellectual disability, ADHD, and OCD, while the non-ASD group was more likely to have co-morbid personality disorders, The ASD group was more likely to commit unplanned simple (non-penetrative) sexual and violent offenses against strangers; the non-ASD group was more likely to commit planned, qualified (penetrative) crimes against known persons. Impulsivity and manipulability were more often contributory in persons with ASD; revenge was more often contributory in persons without ASD. Adults with ASD were more likely to commit crimes on social media.

In this narrative review, we synthesize published research into auditory processing in autistic people and the relationship between auditory processing and autistic attributes in a contextually novel way. The purpose is to understand the relationship between these domains more fully, drawing on evidence gleaned from experiential perspectives through to neurological investigations. We also examine the relationship between auditory processing and diagnosable auditory conditions, such as hyperacusis, misophonia, phonophobia, and intolerance to loud sounds, as well as its relation to sleep, anxiety, and sensory overload. Through reviewing experiential, behavioral and neurological literature, we demonstrate that auditory processes interact with and shape the broader autistic profile—something not previously considered.
