It's great you're looking into ABA and ESDM therapies! A recent study in the journal *Frontiers in Pediatrics* found that both ABA (Applied Behavior Analysis) and ESDM (Early Start Denver Model) led to significant improvements in children with autism after six months. These improvements were seen in areas like cognitive skills, language, social interaction, imitation, emotional expression, and motor skills.

Interestingly, the study also showed that ESDM led to greater gains in social reciprocity, while ABA excelled in gross motor skills. This suggests that the best therapy choice might depend on your child's specific needs.

There's also evidence that early and intensive ABA (20-40 hours/week) can boost adaptive behavior, cognition, and language. Similarly, ESDM has been shown to have moderate effects on cognition and language. I hope this helps!
