Nonverbal learning disorder

The mathematical abilities of children with autism spectrum condition have been understudied. Magnitude representation (e.g. presenting the number of a collection of objects) is a fundamental numerical ability presented since early infancy and is correlated with children's later learning of formal mathematics. It remains unclear about whether children with autism spectrum condition differ from their peers without autism spectrum condition in precision of magnitude representations. This study compared preschool children with and without autism spectrum condition in their precision of magnitude representation with an approximate number comparison task, in which children compared two sets of dots without counting and chose the set with more dots...

Autism spectrum disorder (ASD) is a wide range of diseases characterized by difficulties with social skills, repetitive activities, speech, and nonverbal communication. The Centers for Disease Control (CDC) estimates that 1 in 44 American children currently suffer from ASD. The current gold standard for ASD diagnosis is based on behavior observational tests by clinicians, which suffer from being subjective and time-consuming and afford only late detection (a child must have a mental age of at least two to apply for an observation report)...

BACKGROUND: Difficulties with praxis, the ability to perform learned skilled movements, have been robustly demonstrated in autism spectrum disorder (autism). However, praxis assessment is not routinely included in autism characterization batteries, in part because it is traditionally time consuming to administer and score. We test whether dyspraxia in autism can be captured with a brief measure. METHOD: Youth with autism ( n = 41) and matched typically developing controls ( n = 32), aged 8 to 16 years, completed a 5-minute praxis battery...

Background: Studies on physical activity interventions indicated a facilitative effect on cognitive performance in persons with intellectual disabilities; however, research is scarce, especially in low/middle-income countries. Aim: We explored the effects of a 6-week enriched physical education program on inhibitory control and attention functions in Ecuadorian children with intellectual disabilities. Methods: Thirty children with mild intellectual disabilities (10-14 years old) were randomly assigned to an intervention or control group...

This study examines how intellectual disability nurses employed in residential living services for persons with intellectual disabilities, in Norway, deal with medication management for these individuals. Using a qualitative study, a total of 18 intellectual disability nurses were interviewed as part of four focus groups. The results demonstrate six main challenges: First, Being alone with the responsibility of medication management - a challenge; Second, The need for further competence development; Third, Teaching and supervising unskilled colleagues in safe medication management; Fourth, Interpreting residents with little or only nonverbal communication; Fifth, The need to act as advocates when residents require hospitalization; Sixth, Deficient systems for medication management on several levels...

PURPOSE: Τhe lexical stress pattern (trochaic vs. iambic) may affect various aspects of word learning and word production in children with cochlear implants (CIs). This study aimed to investigate lexical stress effects in word learning by Greek-speaking children with CIs. METHOD: A word learning paradigm, consisting of a word production and a word identification task, was used. A test list of eight pairs of disyllabic nonwords with identical phonological composition and contrasting lexical stress (eight trochaic and eight iambic), along with their referent pictured objects, was constructed and administered to 22 Greek-speaking children with CIs (ages 4;6-12;3 [years;months]) with normal nonverbal IQ and to 22 age-matched controls with normal hearing (NH) and no other difficulties...

3q29 deletion syndrome (3q29del) is associated with neuropsychiatric and neurodevelopmental phenotypes. We previously reported that graphomotor weakness is present in up to 78% of individuals with 3q29del. We have now explored nuances of the graphomotor phenotype and its association with other comorbidities in this population. Participants were recruited from the online 3q29 registry (3q29deletion.org) for two days of deep phenotyping. 32 individuals with 3q29del (62.5% male) were evaluated with the Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI) to assess visual-motor integration...

BACKGROUND: Adults with severe/profound intellectual disability typically face poor communication outcomes as they are often nonverbal and need their supporters to provide for their communication needs. This review aimed to identify studies focused on the communication resources people with severe/profound intellectual disability use for functional communication, and the enablers and barriers to functional communication. METHODS: Nine databases were systematically reviewed with keywords pertaining to the functional communication of adults with severe/profound intellectual disability...

INTRODUCTION: Expressing emotions through spontaneous facial expression is an important nonverbal social communication skill. In our study, we aimed to demonstrate that both children with autism spectrum disorder (ASD) and the non-ASD siblings of children with ASD have deficits in this skill. METHOD: In this study, we analyzed the six core facial emotion expressions of three distinct groups of children - those diagnosed with ASD (n = 60), non-ASD siblings (n = 60), and typically developed children (n = 60)...

Substantial progress has been made in defining children with nonverbal learning disability (NLD), but longitudinal studies are still lacking. To start filling this gap, we examined changes in general cognitive functioning, visuo-constructive skills, and academic profiles in a group of children with NLD, also taking into account any internalizing and externalizing symptom as transdiagnostic features. A total of 30 participants (24 boys) diagnosed with NLD were tested twice, with a three-year gap between the two assessments (T1: at age 8-13; T2: at 11-16), on their cognitive profile, visuospatial abilities, and academic performance (i...

Nonverbal learning disability (NVLD) is a neurodevelopmental disorder characterized by deficits in visuospatial processing but spared verbal competencies. Neurocognitive markers may provide confirmatory evidence for characterizing NVLD as a separate neurodevelopmental disorder. Visuospatial performance and high-density electroencephalography (EEG) were measured in 16 NLVD and in 16 typically developing (TD) children. Cortical source modeling was applied to assess resting-state functional connectivity (rs-FC) in spatial attention networks (dorsal (DAN) and ventral attention networks (VAN)) implicated in visuospatial abilities...

OBJECTIVES: Impairments in neuropsychological functioning (mainly memory, learning, attention, and executive functioning) among persons with long-term opioid use disorder (OUD) have been widely reported, with few studies suggesting that these are not permanent and can improve with abstinence. Thus, present study aimed to evaluate the neuropsychological functioning in persons with OUD and examine the effects of abstinence on the same over a period 8 weeks. METHODS: A total of 50 patients with diagnosis of OUD as per the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria underwent serial longitudinal neuropsychological assessments for executive functioning, attention and concentration, and verbal and nonverbal memory at baseline, 2 weeks, and 8 weeks of abstinence...

Augmentative and alternative communication (AAC) systems are not well-known and broadly used in Thailand. To begin introducing AAC systems and interventions to children with complex communication needs in Thailand, understanding speech-language pathologists' (SLPs) perceptions toward various AAC systems is an important first step. This study assessed SLPs' perceptions of three AAC modalities: gestural communication, communication boards, and iPad1 -based speech-output technologies. A total of 78 SLPs watched three video vignettes of a child using each mode and rated their impressions of intelligibility, ease of learnability and use, effectiveness, and preference...

PURPOSE: Children at the intersections of language learning, racialization, and dis/ability status experience systems of power in a very particular way. This work amplifies the "voices" of bilingual nonspeaking children and their families to upend the notion of educational and medical professionals as the experts. It positions familial ways of being and knowing as central to learning and offers educators tools to actively collaborate with and follow the lead of children and families to engage in "reciprocal carryover...

IMPORTANCE: Autism spectrum disorder (ASD) is associated with significant clinical, neuroanatomical, and genetic heterogeneity that limits precision diagnostics and treatment. OBJECTIVE: To assess distinct neuroanatomical dimensions of ASD using novel semisupervised machine learning methods and to test whether the dimensions can serve as endophenotypes also in non-ASD populations. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used imaging data from the publicly available Autism Brain Imaging Data Exchange (ABIDE) repositories as the discovery cohort...

BACKGROUND AND HYPOTHESIS: Deficits in performing and interpreting communicative nonverbal behaviors, such as gesture, have been linked to varied psychopathology and dysfunction. Some evidence suggests that individuals at risk for psychosis have deficits in gesture interpretation and performance; however, individuals with internalizing disorders (eg, depression) may have similar deficits. No previous studies have examined whether gesture deficits in performance and interpretation are specific to those at risk for psychosis...

Individuals with autism spectrum disorder can find behavioural flexibility challenging, often exhibited in terms of repetitive behaviours or restricted ranges of interests and activities. An inability to shift efficiently from one situation to another is connected with problems in daily life, and identifying factors associated with this ability may help develop teaching strategies to improve behavioural flexibility. Some existing findings imply shifting performance for individuals with autism spectrum disorder is better with nonverbal, compared to verbal, feedback - even for those with strong verbal abilities...

Most speech-language pathologists (SLPs) in Malaysia practice with an undergraduate degree, which provides them with limited knowledge about and training in augmentative and alternative communication (AAC). This limited knowledge and training may affect their confidence and competence when introducing and using AAC with individuals for whom it is required. This study aimed to obtain feedback, via semi-structured interviews, from a group of 11 Malaysian university students who participated in an AAC training program about their experiences participating in and the effectiveness of the training program...

Potassium voltage-gated channel subfamily B member 1 ( KCNB1 ) encodes Kv2.1 potassium channel. KCNB1 mutations are known to cause global developmental delay, behavioral disorders, and various epilepsies. Most variants occur de novo and are rarely inherited. Here, we report a 14-year-old male patient who was admitted to our clinic with seizures, developmental delay history, and intellectual disability. Brain magnetic resonance image (MRI) was normal and electroencephalogram (EEG) showed spike and sharp-wave complexes emerging in the left hemisphere parietooccipital areas, which were paroxysmally generalized...

Attention Deficit/Hyperactivity disorder (ADHD) is one of the most common disorders in school-age children. In addition to learning difficulties associated with the disorder's core symptoms of inattention and hyperactivity, children with ADHD display substantial social impairments. Methylphenidate (MPH) in formulations such as Ritalin or Concerta mitigates inattention and hyperactivity, but the effects of the therapy on social behavior in children with ADHD are not clear. This review aims to determine the effectiveness of short term (up to 6 months) MPH treatment on three domains of social skills in children aged 6-14 with ADHD: (i) Recognition of nonverbal emotional expressions, which are a marker of inherent (unlearned) social understanding, (ii) theory of mind (ToM) components that relate to learned cognition and social communication, and (iii) social competence in everyday environments...
