A major review in *Pediatrics* found that early interventions like the Early Start Denver Model (ESDM)—which blends ABA techniques with relationship-based approaches—can significantly improve outcomes for young children with autism. Research shows these therapies are most effective when started before age 3, targeting communication, social skills, and behavior (Autism Speaks, NICHD). Structured programs focusing on play, speech, and cognitive development show strong evidence for reducing core symptoms (Frontiers, Cross River Therapy). For specifics, check the *Frontiers* systematic review on neural effects of movement therapies or NICHD’s guidelines on early intervention strategies. Let me know if you'd like links!
