Autism Spectrum Disorder01:19

Autism Spectrum Disorder

905
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

718
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Conduct Disorder01:28

Conduct Disorder

458
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

584
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Learning Disabilities01:25

Learning Disabilities

550
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Social Anxiety Disorder01:28

Social Anxiety Disorder

414
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

Summary
This summary is machine-generated.

Children with childhood apraxia of speech (CAS) frequently experience motor impairments and developmental coordination disorder (DCD) risk. Early screening for DCD is crucial for effective intervention in CAS.

Area of Science:

  • Pediatric Neurology
  • Developmental Psychology
  • Speech-Language Pathology

Background:

  • Childhood apraxia of speech (CAS) is a complex motor speech disorder.
  • Motor impairments are frequently observed in children with CAS.
  • Developmental coordination disorder (DCD) shares overlapping symptoms with CAS.

Purpose of the Study:

  • To investigate the prevalence of motor impairments and DCD risk in children diagnosed with CAS.
  • To identify specific motor deficits associated with DCD in this population.
  • To evaluate the effectiveness of current assessment tools for DCD in children with CAS.

Main Methods:

  • Prospective cohort study of 105 children (aged 5-15 years) with CAS.
  • Utilized the Developmental Coordination Disorder Questionnaire (DCD-Q), visuomotor precision subtest, Vineland Adaptive Behaviour Scales (Vineland-3), and Full-scale IQ (FSIQ) assessments.

  • Employed statistical analyses including logistic regression and ROC analyses to identify predictors of DCD risk.

    • Main Results:

    • 82% of children with CAS exhibited motor impairments; 63% screened positive for DCD risk.
    • Visuomotor precision deficits were present in 71% of participants.
    • The Vineland-3 motor subtest and visuomotor precision were significant predictors of DCD risk (OR=7.17 and OR=4.90, respectively), independent of FSIQ.

    Conclusions:

    • Children with CAS have a high prevalence of DCD risk and visuomotor impairments, irrespective of intellectual ability.
    • The Vineland-3 motor subtest is not recommended for DCD screening in this population.
    • Routine screening for DCD is essential for timely and targeted interventions in children with CAS.
