It's great you're looking into ABA and ESDM therapies! Recent studies show both can lead to significant developmental gains for young children with autism.

ESDM (Early Start Denver Model) often excels in broad social and language improvements, while high-intensity ABA (Applied Behavior Analysis) shows excellent benefits in communication, cognition, and adaptive skills, especially when delivered at 26-40 hours per week. A comparative study even found ESDM produced superior gains over ABA in personal-social development and speech.

Starting early (before age 3) and involving parents are key for optimal results! A longitudinal ESDM trial reported lasting improvements in repetitive behaviors and autism severity.
