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 for autistic children across different areas over six months [1].

Interestingly, the study found that ESDM was particularly helpful in improving social responsiveness, while ABA showed better results in gross motor skills [1]. Some studies also suggest that early ESDM intervention (around 20 hours/week) may lead to lasting gains, like reduced repetitive behaviors [2]. Remember, the best approach is to personalize the therapy to match your child's specific needs, and involve parents in the process [1].
