What are the early signs of autism in young children?

Introduction

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by deficits in social communication and the presence of repetitive behaviors. Identifying early signs of autism in young children is crucial for timely intervention, which can significantly improve outcomes.

Key Insights

Decline in Social Communication Behaviors:
- Children later diagnosed with ASD show a significant decline in gaze to faces, shared smiles, and vocalizations to others starting around 12 months of age .
Atypical Social and Communication Development:
- Early signs include reduced eye contact, lack of social smiling, and delayed speech development. These signs can be observed as early as 6 to 12 months .
Repetitive Behaviors and Play Differences:
- Repetitive behaviors and differences in play, imitation, and feeding habits become noticeable in the second year of life .
Temperament and Sensory Responses:
- Children with ASD may exhibit atypical temperament, such as extreme passivity or distress reactions, and unusual sensory-oriented behaviors by 12 months .
Parental Concerns and Retrospective Observations:
- Parents often report concerns about vision and hearing in the first year, and retrospective analysis of home videos can reveal early signs like lack of pre-language and social engagement .

Conclusion

Early signs of autism in young children typically emerge between 6 to 18 months and include a decline in social communication behaviors, atypical social interactions, repetitive behaviors, and unusual sensory responses. Recognizing these signs early can lead to timely interventions, potentially improving developmental outcomes for children with ASD.
