Autism spectrum disorder (ASD) describes a set of neurodevelopmental disorders. Despite extensive ASD research lasting more than 60 years, its causes are still unknown. Without indicating the etiology, its development cannot be stopped. Over the years, both the definition and diagnostic criteria have developed. The number of ASD incidence is…

Our study examines the Diagnostic and Statistical Manual--Fifth Edition (DSM-5) and Diagnostic and Statistical Manual--Fourth Edition, Text Revision (DSM-IV-TR) when applied concurrently against the best estimate clinical diagnoses for 110 children (5.1-19.6 years old) referred for diagnostic assessments of Autism Spectrum Disorder (ASD) in a…

Introduction: The objective of this study is to find out if there are differences in selective and sustained attention between children with different subtypes of ADHD and children with learning disorders (LD), in order to improve the differential diagnosis between ADHD and PD and between the different subtypes of ADHD. Method: The sample…

Background: We discuss a free software system (Computerized Language Analysis [CLAN]) that can enable fast, thorough, and informative language sample analysis (LSA). Method: We describe methods for eliciting, transcribing, analyzing, and interpreting language samples. Using a hypothetical child speaker, we illustrate use KidEval to generate a…

Screening for autism spectrum disorder is the first step toward early detection and diagnosis, thereby impacting the likelihood of children accessing early intervention and, importantly, improving long-term outcomes. This systematic review aimed to (a) establish a clear baseline of autism spectrum disorder screening tools currently used throughout…

"The Autism Spectrum Handbook & Resource Guide" combines valuable, easy-to-understand educational information for consumers, patients, and their families, with official reports and releases about monitoring childhood growth and important milestones, community statistics, living with an ASD, and treatments and further resources for…

Purpose: The purpose of this 2nd article in this supplement is to report validity support findings for the Pause Marker (PM), a proposed single-sign diagnostic marker of childhood apraxia of speech (CAS). Method: PM scores and additional perceptual and acoustic measures were obtained from 296 participants in cohorts with idiopathic and…

Purpose: The goal of this article (PM I) is to describe the rationale for and development of the Pause Marker (PM), a single-sign diagnostic marker proposed to discriminate early or persistent childhood apraxia of speech from speech delay. Method: The authors describe and prioritize 7 criteria with which to evaluate the research and clinical…

Deficits in reporting past behavior may have implications for a child's social development and safety. Behavioral interpretations of memory and research on do/say correspondence provide valuable strategies to teach reporting past behavior when deficits are observed. The current study examined procedures to teach accurate reporting of past behavior…

Introduction: There are different tests that assess attention and can help to make a differential diagnosis between ADHD and Learning Disabilities (LD), but there appears to be little research on the convergent and predictive validity of these tests. The aim of this study was to analyze the convergent validity of the EMAV, Caras, d2, AGL, CPT-II…

Background: Autism spectrum disorder (ASD) and social pragmatic communication disorder (SPCD) are two neurodevelopmental disorders with many similarities in affected individuals' impairments in social-communicative and pragmatic development. A central question pertaining to their differentiation concerns whether the distinction is truly…

Diagnosis of Autism Spectrum Conditions (ASC) can be an extended procedure since ASC tend to both vary greatly across individual symptoms and diagnostic pathways with serious challenges to opportune access and diagnosis in low resource settings. We adapted the Q-CHAT-25 for use in a routine health check-ups programme at Chilean primary health…

Psychiatric/neurodevelopmental diagnoses have expanded in number and scale with increased influence over matters of education and upbringing. One of the most common psychiatric diagnoses among children and adolescents is attention deficit hyperactivity disorder (ADHD). The dominant perspective of ADHD is biomedical, where ADHD is defined as a…

The diagnostic utility of the Woodcock-Johnson III Tests of Cognitive Abilities and Clinical Clusters was assessed in a sample of 52 children (26 Attention Deficit/Hyperactivity Disordered (ADHD) and 26 matched controls). Multivariate analysis of variance followed by post-hoc testing and d-ratios yielded some statistically significant and…

The objective of our study was to evaluate the frequency of treatable inborn errors of metabolism (IEM) in a clinical sample of Mexican children and adolescents with neurodevelopmental disorders (NDD). Amino acids and acylcarnitines in blood samples of 51 unrelated children and adolescents were analyzed by tandem mass spectrometry to detect…
