Digit Ratio 2D:4D in Relation to Autism Spectrum Disorders, Empathizing, and Systemizing: A Quantitative Review / Johannes HONEKOPP in Autism Research, 5-4 (August 2012)  

Public ISBD [article]  inAutism Research > 5-4 (August 2012) . - p.221-30 Titre : Digit Ratio 2D:4D in Relation to Autism Spectrum Disorders, Empathizing, and Systemizing: A Quantitative Review Type de document : Texte imprimé et/ou numérique Auteurs : Johannes HONEKOPP, Auteur Année de publication : 2012 Article en page(s) : p.221-30 Langues : Anglais (eng) Mots-clés : autism  digit ratio  prenatal testosterone  empathizing  systemizing  sex differences Index. décimale : PER Périodiques Résumé : Prenatal testosterone (PT) effects have been proposed to increase systemizing (the drive to understand lawful input–output relationships), to decrease empathizing (the drive to understand others), and to cause autism via hypermasculinization of the brain. Digit ratio 2D:4D is a putative marker of PT effects in humans. An online study (n = 1896) into the relationship between the Reading the Mind in the Eyes Test (a widely used measure of empathizing) and self-measured 2D:4D in a nonclinical sample is reported. No evidence for a link between empathizing and 2D:4D in either females or males emerged. Further, three meta-analyses are presented that look into the relationships of 2D:4D with autism spectrum disorder (ASD), systemizing, and empathizing. 2D:4D was substantially lower (more masculine) in ASD-affected individuals than in normal controls (d = −0.58, P < 0.001). However, 2D:4D was found to be virtually unrelated to systemizing and empathizing in normal adults. The results support the idea that high PT is a risk factor for autism, but they challenge the view that PT substantially contributes to sex differences in systemizing and empathizing. Possibly, this pattern reflects an interaction effect, whereby PT drives ASD characteristic changes only in brains with a specific damage.

Perceptual and Neural Response to Affective Tactile Texture Stimulation in Adults with Autism Spectrum Disorders / Carissa J. CASCIO in Autism Research, 5-4 (August 2012)

We used psychophysics and functional magnetic resonance imaging (fMRI) to investigate responses to somatosensory stimulation with three textured surfaces that spanned a range of roughness and pleasantness in a sample of adults with ASD and a control group. While psychophysical ratings of roughness and pleasantness were largely similar across the two groups, the ASD group gave pleasant and unpleasant textures more extreme average ratings than did controls. In addition, their ratings for a neutral texture were more variable than controls, indicating they are less consistent in evaluating a stimulus that is affectively ambiguous. Changes in brain blood oxygenation level-dependent (BOLD) signal in response to stimulation with these textures differed substantially between the groups, with the ASD group exhibiting diminished responses compared to the control group, particularly for pleasant and neutral textures. For the most unpleasant texture, the ASD group exhibited greater BOLD response than controls in affective somatosensory processing areas such as the posterior cingulate cortex and the insula. The amplitude of response in the insula in response to the unpleasant texture was positively correlated with social impairment as measured by the Autism Diagnostic Interview-Revised (ADI-R). These results suggest that people with ASD tend to show diminished response to pleasant and neutral stimuli, and exaggerated limbic responses to unpleasant stimuli, which may contribute to diminished social reward associated with touch, perpetuating social withdrawal, and aberrant social development.

Changes in the Sulcal Size Associated With Autism Spectrum Disorder Revealed by Sulcal Morphometry / Mahsa SHOKOUHI in Autism Research, 5-4 (August 2012)

Because of the heterogeneity of the disorder, several biomarkers have been suggested so far. Here, we explore the potential of sulcal surface and length as biomarkers. Three-dimensional T1-weighted images of 15 adolescents of normal intelligence with ASD and 15 age-, sex-, and intelligence quotient-matched control adolescents were analysed using Brainvisa 4.0 (http://www.brainvisa.info), which automatically extracts the cortical folds and labels them as 59 sulcal pieces. For each sulcus, the surface, length, and mean geodesic depth were computed using morphometry analysis within this software package. General linear model was conducted to compare the estimated values for the two groups, ASD and control. In the ASD group, the left insula and the right intraparietal sulcus (IPS) had significantly higher values for surface and length, respectively. Nonetheless for all sulcal pieces, the mean geodesic depth was not significantly different between the two groups. Our results suggest that sulcal surface and length can have correlation with morphological changes of cortex in ASD. Greater surface area and length in insula and IPS, respectively, may reflect greater folding. This could result in greater separation of functions with an impact upon the integrative functions of these regions.

Same but Different: 9-Month-Old Infants at Average and High Risk for Autism Look at the Same Facial Features but Process Them Using Different Brain Mechanisms / Alexandra P.F. KEY in Autism Research, 5-4 (August 2012)

Eye tracking and visual event-related potentials (ERPs) were recorded in 35 infants (20 average-risk typical infants, 15 high-risk siblings of children with ASD) while they viewed photographs of a smiling unfamiliar female face. On 30% of the trials, the eyes or the mouth of that face was replaced with corresponding features from a different female. There were no group differences in the number, duration, or distribution of fixations, and all infants looked at the eyes and mouth regions equally. However, increased attention to the mouth was associated with weaker receptive communication skills and increased attention to the eyes correlated with better interpersonal skills. ERP results revealed that all infants detected eye and mouth changes but did so using different brain mechanisms. Changes in facial features were associated with changes in activity of the face perception mechanisms (N290) for the average-risk group but not for the high-risk infants. For all infants, correlations between ERP and eye-tracking measures indicated that larger and faster ERPs to feature changes were associated with fewer fixations on the irrelevant regions of stimuli. The size and latency of the ERP responses also correlated with parental reports of receptive and expressive communication skills, suggesting that differences in brain processing of human faces are associated with individual differences in social-communicative behaviors.

The ADOS Calibrated Severity Score: Relationship to Phenotypic Variables and Stability over Time / Stacy SHUMWAY in Autism Research, 5-4 (August 2012)

Recently, Gotham, Pickles, and Lord published a severity metric (calibrated severity scores; CSS) that takes into account age and language level and is based on raw total scores of the Autism Diagnostic Observation Schedule (ADOS), a standardized measure commonly used in autism diagnosis. The present study examined psychometric characteristics of the CSS compared to raw scores in an independent sample of 368 children aged 2 to 12 years with autism, pervasive developmental disorder-not otherwise specified (PDD-NOS), non-spectrum delay, or typical development. Reflecting the intended calibration, the CSS were more uniformly distributed within clinical diagnostic category and across ADOS modules than were raw scores. Cross-sectional analyses examining raw and severity scores and their relationships to participant characteristics revealed that verbal developmental level was a significant predictor of raw score but accounted for significantly less variance in the CSS. Longitudinal analyses indicated overall stability of the CSS over 12 to 24 months in children with autism. Findings from this study support the use of the CSS as a more valid indicator of autism severity than the ADOS raw total score, and extend the literature by examining the stability over 12 to 24 months of the CSS in children with ASD.

Inactivating mutations in GAN cause the autosomal recessive disorder giant axonal neuropathy, not present in our patient. CMIP was recently implicated in the etiology of specific language impairment by genome-wide association analysis. It modulates phonological short-term memory and hence plays an important role in language acquisition. Overlaps of specific language impairment and autism have been debated in the literature regarding the phenotypical language profile as well as etiology. Our patient illustrates that haploinsufficiency of CMIP may contribute to autism spectrum disorders. Our finding further supports the existence of a genetic overlap in the etiology of specific language impairment and autism.
