Parent-child interaction related to brain functional alterations and development outcomes in autism spectrum disorder: A study based on resting state-fMRI.
In preschool autism, more parent-child play links to better skills through calmer cingulate and frontal brain activity.
01Research in Context
What this study did
Xue et al. (2024) watched how often preschoolers with autism played and talked with their parents. They also took resting-state fMRI pictures of each child’s brain. Then they checked if more parent-time linked to better development scores and lower autism traits.
The team looked at two spots: the left cingulate and the right medial superior frontal area. They wanted to see if activity in these spots explained why some kids improved more.
What they found
Kids who had more back-and-forth with parents showed milder autism features and higher developmental quotients. The brain pictures told the story: calmer activity in the chosen frontal and cingulate regions acted like a bridge between parent-time and better skills.
In plain words, richer play-and-talk moments went hand-in-hand with steadier brain rhythms and stronger learning.
How this fits with other research
Temelturk et al. (2021) saw weaker parent-child bonds in autism but could not explain why. Yang adds the missing brain link, so the older study now makes fuller sense.
Karavallil Achuthan et al. (2023) and Guo et al. (2024) also used resting-state fMRI in autistic kids. They found dampened or jumpy low-frequency activity, yet never tied it to daily family life. Yang shows that parent interaction can shape those very signals.
Papageorgopoulou et al. (2024) moved the clock backward, finding poor infant attentiveness at eight months predicts later autism. Yang moves the lens forward, proving the preschool years still offer a window where parent engagement can nudge both brain and behavior.
Why it matters
You now have brain data telling you that every extra minute of joint play counts. Coach parents to stay face-to-face, imitate, and expand language. The cingulate and medial frontal areas are still flexible, so steady interaction may keep calming them and lift developmental scores.

03Original abstract
BACKGROUND: Limited study has investigated the influence of parent-child interaction on brain functional alterations and development outcomes of autism spectrum disorder (ASD) children. This pilot study aimed to explore the relationship between parent-child interaction, brain functional activities and development outcomes of ASD children. METHODS: and Procedures: 653 ASD with an average age of 41.06 ± 10.88 months and 102 typically developmental (TD) children with an average age of 44.35 ± 18.39 months were enrolled in this study, of whom 155 ASD completed brain rs-fMRI scans. The amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo) measured using resting-state functional magnetic resonance imaging (rs-fMRI) data reflect local brain function. The parent-child interaction was assessed by the Chinese Parent-child Interaction Scale (CPCIS). Childhood Autism Rating Scale (CARS) and developmental quotient (DQ) indicated development outcomes. OUTCOMES AND RESULTS: Total CPCIS score was negatively correlated with CARS total score, and positively correlated with DQ. The frequency of parent-child interaction was negatively correlated with ALFF values in the left median cingulate and paracingulate gyri (DCG.L) and ReHo values in the right superior frontal gyrus, medial (SFGmed.R)(P < 0.05, FDR correction). ALFF values in the DCG.L and ReHo values in the SFGmed.R play complete mediating roles in the relationship between parent-child interaction and performance DQ. CONCLUSION AND IMPLICATIONS: This study suggest that parent-child interaction has an impact on autistic characteristics and DQ of ASD children. Local brain regions with functional abnormalities in the DCG.L and SFGmed.R may be a crucial factors affecting the performance development of ASD children with reduced parent-child interaction.
