Exposure to ACEs is associated with adult ASD psychological comorbidities, such as posttraumatic stress disorder (PTSD). Occurrence of intrusive event reexperiencing, characteristic of PTSD, often causes social dysfunction in adults with ASD, but its pathological basis is unclear. This study examined brain regions related to the severity of intrusive reexperiencing and explored whether ACE severity was associated with that of intrusive reexperiencing and/or extracted regional gray matter volume. Forty-six individuals with ASD and 41 TD subjects underwent T1-weighted magnetic resonance imaging and evaluation of ACEs and intrusive reexperiencing. Brain regions related to the severity of intrusive reexperiencing in both groups were identified by voxel-based whole brain analyses. Associations among the severity of intrusive reexperiencing, that of ACEs, and gray matter volume were examined in both groups. The severities of intrusive reexperiencing and ACEs were significantly associated with reduced gray matter volume in the right precuneus in individuals with ASD but not in TD subjects. Although the right precuneus gray matter volume was smaller in individuals with ASD and severe ACEs than in those with mild ACEs or TD subjects, it was similar in the latter two groups. However, ACE-dependent gray matter volume reduction in the right precuneus led to intrusive reexperiencing in individuals with ASD. This suggests that exposure to ACEs is associated with right precuneus gray matter reduction, which is critical for intrusive reexperiencing in adults with ASD. LAY SUMMARY: Individuals with autism spectrum disorder (ASD) are at increased risk of adverse childhood experiences (ACEs) and of subsequent manifestation of intrusive reexperiencing of stressful life events. The present study found that reduced gray matter volume in the right precuneus of the brain was associated with more severe intrusive reexperiencing of ACEs by individuals with ASD. These results suggest that ACEs affect neural development in the precuneus, which is the pathological basis of intrusive event reexperiencing in ASD.

Microstructural Anomalies Evaluated by Neurite Orientation Dispersion and Density Imaging Are Related to Deficits in Facial Emotional Recognition via Perceptual-Binding Difficulties in Autism Spectrum Disorder / Fumihiko YASUNO in Autism Research, 13-5 (May 2020)

We tested the hypothesis that ASD patients exhibit difficulties in facial emotional recognition via perceptual binding difficulties due to weak coherence. We assessed 18 ASD and 27 typically developing individuals for their ability to identify emotional expressions from faces in pictures moving behind a narrow vertical and horizontal slit. In this task, only a single local piece of facial information was provided at any one time through the slit. Using a voxel-based analysis of neurite-orientation dispersion and density imaging (NODDI), we examined the relationship between NODDI index values at each voxel and the behavioral performance of ASD patients in the slit-viewing paradigm. ASD patients demonstrated impaired recognition of facial emotional expression only in horizontal slit-viewing. This deficit was associated with deficits in communication ability. Voxel-based analysis revealed significant negative correlations between behavioral deficits in horizontal slit-viewing and NODDI index values in clusters including the ventral occipital complex region, superior temporal/parietal association areas, and forceps major of the corpus callosum. Our results indicated deficits for the first time in perceptual integration of facial expression across hemispheres in ASD patients due to microstructural disturbances in the corpus callosum and areas related to viewing of the human face. This may underscore the difficulties faced by ASD patients in understanding the emotions of other people, contributing to impairments in communication ability in ASD patients.
