Autistic children: diagnosis and clinical features

Area of Science:

• Neuroscience
• Developmental Psychology
• Genetics

Background:

• Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social interaction, communication, and restricted interests.
• Etiology is diverse, including genetic and non-genetic factors, with unknown causes in most cases.
• ASD affects boys more frequently than girls and typically manifests in the preschool years.

Purpose of the Study:

• To provide a comprehensive overview of Autism Spectrum Disorder (ASD).
• To discuss the varied etiologies, clinical manifestations, and diagnostic features of ASD.
• To outline the impact of ASD on cognitive skills, language development, and potential interventions.

Main Methods:

• Review of existing literature on Autism Spectrum Disorder.
• Analysis of clinical observations regarding social, communication, and behavioral aspects of ASD.
• Examination of neuroimaging findings and cognitive assessments in individuals with ASD.

Main Results:

• ASD presents with a wide spectrum of severity, often accompanied by motor, sensory, affective, and attentional challenges.
• A significant proportion of individuals with ASD experience seizures and exhibit abnormal EEG patterns.
• Neuroimaging reveals developmental brain abnormalities in a minority, with intelligence ranging from profound impairment to giftedness.

Conclusions:

• Cognitive skills in ASD are often uneven, with relative strengths in nonverbal abilities.
• All preschool-aged children with ASD exhibit developmental language disorders, impacting both expressive and receptive language.
• While no cure exists, interventions targeting social skills, communication, and symptom management (e.g., for attention and seizures) can significantly improve outcomes, enabling varying degrees of independence in adulthood.
