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

Interestingly, the study found that ESDM led to greater gains in social reciprocity, while ABA showed more improvement in gross motor skills. Also, high-intensity early ABA is linked to about 50% of children catching up to their peers in cognitive and adaptive functioning.
