Summary
This study on childhood developmental delay (DD) found cognitive, language, and motor impairments are most common. Identifying causes of DD is challenging due to its diverse nature.
Area of Science:
- Pediatric Medicine
- Developmental Psychology
- Genetics
Background:
- Developmental delay (DD) affects numerous children globally.
- Understanding functional domains and etiological factors is crucial for early intervention.
- Previous research highlights the heterogeneity of DD, complicating diagnosis and treatment.
Purpose of the Study:
- To identify the functional domains and etiological risk factors in children diagnosed with developmental delay (DD).
- To categorize subtypes of DD and analyze the prevalence of associated disorders and risk factors.
Main Methods:
- A retrospective chart review of 1192 children evaluated for DD or behavioral problems over 41 months.
- Clinical evaluation, laboratory investigations, and psychological assessments were conducted.
- Children were classified into six functional subtypes of DD.
Main Results:
- Developmental delay (DD) was diagnosed in all 1192 children, with cognitive DD (86.7%), language DD (58.4%), and motor DD (47.9%) being most prevalent.
- Males were more frequently diagnosed with DD (male to female ratio 2.3:1).
- Identifiable etiological risk factors were found in only 20.5% of cases, and 35.6% had associated disorders.
Conclusions:
- Cognitive, language, and motor delays are the most common functional domains affected in children with DD.
- Developmental delay (DD) is more prevalent in males.
- The heterogeneity of DD presents significant challenges in identifying specific etiological risk factors.

01:25Learning Disabilities
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.

01:29Intellectual Disability
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
01:19Autism Spectrum Disorder
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.

01:27Introduction to Developmental Psychology
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...
01:30Attention-Deficit/Hyperactivity Disorder
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.

01:29Three Developmental Domains
Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
