Great question! Research shows early intervention for autism can significantly improve outcomes, especially when started before age 3. Studies highlight approaches like the Early Start Denver Model (ESDM), which blends ABA techniques with relationship-based strategies, showing strong results in boosting social and communication skills. Evidence-based reviews also support intensive behavioral interventions (EIBI) and parent-mediated models for enhancing development. The Missouri Autism Guidelines and Children's Hospital of Philadelphia offer helpful resources on proven therapies. Early intervention often leads to reduced symptom severity and better adaptive skills over time. Let me know if you'd like links to specific studies or programs!
