It's great you're looking into ABA and ESDM therapies! A recent study in 2025 showed that both ABA (Applied Behavior Analysis) and ESDM (Early Start Denver Model) can lead to significant improvements in children with autism after about six months. These improvements span areas like cognitive skills, language, social interaction, motor skills, and emotional expression, according to PEP-3 assessments.

Interestingly, the study also found that ESDM might lead to greater gains in social reciprocity, while ABA may be more effective for gross motor skills. So, the best choice might depend on your child's specific needs. You can find the full study here: https://www.frontiersin.org/jo....urnals/pediatrics/ar
