Novel Prefrontal Synthesis Intervention Improves Language in Children with Autism

Area of Science:

• Neuroscience
• Developmental Psychology
• Clinical Psychology

Background:

• Prefrontal synthesis (PFS) involves mentally juxtaposing visuospatial objects.
• Impaired PFS is linked to language comprehension deficits in 30-40% of individuals with autism spectrum disorder (ASD).
• These deficits include understanding spatial prepositions, reversible, and recursive sentences.

Purpose of the Study:

• To evaluate the efficacy of a PFS-targeting intervention for improving language skills in children with ASD.
• To assess the impact of the Mental Imagery Therapy for Autism (MITA) application on language acquisition.

Main Methods:

• A three-year clinical trial involving 6454 children with ASD (ages 2-12).
• Intervention group used tablet-based exercises (MITA) focusing on mental object juxtaposition.
• Control group matched by age, gender, language, sociability, cognition, and health using propensity score analysis.

Main Results:

• The intervention group showed a 2.2-fold improvement in receptive language (p < 0.0001) compared to the control group.
• A 1.4-fold improvement in expressive language was observed in the intervention group (p = 0.0144).
• No significant changes were noted in language subscales not targeted by the intervention.

Conclusions:

• Targeted training of PFS can enhance language acquisition in children with ASD.
• The MITA intervention demonstrates potential for improving language skills in this population.
• Further investigation via a randomized controlled study is warranted.
