Abstract

Introduction: Autism Spectrum Disorder is a complex neurodevelopmental condition. Earlyidentification of symptoms is crucial for timely intervention, yet diagnosing very young childrencan be challenging due to the variability in symptom presentation and the influence of otherdevelopmental factors. This study aimed to find the prevalence of the emergence of early behaviouralsigns in Nepalese children with Autism Spectrum Disorder. Methods: A descriptive cross-sectional study was conducted at the Centre for Autism in Kathmandu,Nepal, from January 2023 to June 2023. Ethical approval was obtained, and a sample of 120 childrendiagnosed with Autism Spectrum Disorder was included in the study. Convenience samplingmethod was used. Point estimate at 95% Confidence Interval was calculated. Results: Among 120 children with Autism Spectrum Disorder, the prevalence of emergence of earlybehavioural signs was seen in 112 (93.33%) (88.83-97.77, 95% Confidence Interval) children. Conclusions: This study provides insights into the emergence of early behavioural signs in Nepalesechildren with Autism Spectrum Disorder which align with global patterns in prevalence and severity.
