It's great you're looking into the long-term outcomes of ABA and ESDM! Both are fantastic, evidence-based early interventions for autism, showing significant improvements in cognitive, language, social, and adaptive skills.

A recent study in the journal *Frontiers in Pediatrics* found that after 6 months, both ABA and ESDM led to improvements, but ESDM showed greater gains in social reciprocity, while ABA excelled in gross motor skills.

Other studies have found that intensive ABA can lead to long-term IQ gains, while ESDM can enhance social communication and neural activity in social brain regions. Some comparative reviews suggest that ESDM might be stronger for social domains, while ABA is great for structured skills.

Ultimately, the best approach depends on the individual child!
