It's great you're looking into ABA and ESDM therapies! A recent study showed that both ABA (Applied Behavior Analysis) and ESDM (Early Start Denver Model) can lead to significant improvements in children with autism over six months.

The study found improvements in areas like cognitive abilities, language, social skills, motor development, and emotional expression. Interestingly, ESDM showed greater improvement in social reciprocity, while ABA led to greater improvement in gross motor skills. This suggests that the best approach might be to personalize the intervention based on your child's specific needs. For example, clinicians might use ESDM for social communication and ABA for adaptive behavior support.
