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 improvements in language, social interaction, and motor skills for children with autism over six months.

Interestingly, ESDM was particularly effective in boosting social responsiveness, while ABA excelled in improving gross motor skills. A meta-analysis also confirmed ESDM's positive effects on cognition and language. Starting these interventions early, ideally before age 3, can really maximize the benefits for IQ, language, and social skills.
