Autism Spectrum Disorder Diagnosis and Evaluation in Pediatric Care

Autism spectrum disorder (ASD) encompasses a range of neurodevelopmental conditions characterised by differences in social communication, restricted interests and repetitive behaviours. Early identification in paediatric settings is essential to initiate timely intervention that supports developmental trajectories and quality of life. Diagnosis typically involves a multidisciplinary assessment combining developmental history, structured behavioural observations and caregiver‐reported instruments. Genetic evaluation and neurological examination may uncover syndromic or monogenic contributors, while metabolic and sensory assessments can refine differential diagnosis. Despite established clinical guidelines, delays of several years between parental concern and formal diagnosis remain common, particularly in under-resourced or rural communities. Emerging approaches seek to augment clinical expertise with objective metrics—such as social visual engagement patterns, digital phenotyping and machine-learning analysis of behavioural data—to improve diagnostic accuracy, reduce subjectivity and facilitate remote assessment. International collaborations and standardised datasets are accelerating the search for reliable diagnostic biomarkers. Telehealth and hybrid service models have expanded access to specialist evaluation, enabling observation of naturalistic behaviours and caregiver coaching across diverse settings. Collectively, these developments underscore a shift towards data-driven, family-centred pathways that integrate biological, behavioural and technological modalities to enhance early detection and personalised care planning.
