More than maths and mindreading: Sex differences in empathizing/systemizing covariance / Jeffrey M. VALLA in Autism Research, 3-4 (August 2010)

Covariance data on empathizing and systemizing traits have alternately suggested inversely dependent, independent, and sex-dependent (one sex dependent, the other independent) structures. A total of 144 normal undergraduates (65 men, 79 women) completed the Reading the Mind in the Eyes, Embedded Figures, and Benton face recognition tests, the Autism Spectrum Quotient, and measures of digit length ratio and field of study; some also completed tests of motion coherence threshold (64) and go/no-go motor inhibition (128). Empathizing and systemizing traits were independent in women, but largely dependent in men. In men, level of systemizing skill required by field of study was directly related to social interactive and mindreading deficits; men's social impairments correlated with prolonged go/no-go response times, and men tended to apply systemizing strategies to solve problems of empathizing or global processing: rapid perceptual disembedding predicted heightened sensitivity to facial emotion. In women, level of systemizing in field was related to male-typical digit ratios and autistic superiorities in detail orientation, but not to autistic social and communicative impairments; and perceptual disembedding was related to social interactive skills but independent of facial emotion and visual motion perception.

Altered medial prefrontal cortex and dorsal raphé activity predict genotype and correlate with abnormal learning behavior in a mouse model of autism-associated 2p16.3 deletion / Rebecca B. HUGHES in Autism Research, 15-4 (April 2022)  

Public ISBD [article]  inAutism Research > 15-4 (April 2022) . - p.614-627 Titre : Altered medial prefrontal cortex and dorsal raphé activity predict genotype and correlate with abnormal learning behavior in a mouse model of autism-associated 2p16.3 deletion Type de document : texte imprimé Auteurs : Rebecca B. HUGHES, Auteur ; Jayde WHITTINGHAM-DOWD, Auteur ; Steven J. CLAPCOTE, Auteur ; Susan J. BROUGHTON, Auteur ; Neil DAWSON, Auteur Article en page(s) : p.614-627 Langues : Anglais (eng) Mots-clés : Animals  Autism Spectrum Disorder/genetics  Autistic Disorder  Disease Models, Animal  Dorsal Raphe Nucleus  Genotype  Humans  Male  Mice  Prefrontal Cortex/diagnostic imaging  Reversal Learning  cognitive neuroscience  copy number variation/copy number variants  frontal lobe  genotype-phenotype correlation  imaging genetics  mouse models  serotonin Index. décimale : PER Périodiques Résumé : 2p16.3 deletion, involving NEUREXIN1 (NRXN1) heterozygous deletion, substantially increases the risk of developing autism and other neurodevelopmental disorders. We have a poor understanding of how NRXN1 heterozygosity impacts on brain function and cognition to increase the risk of developing the disorder. Here we characterize the impact of Nrxn1 heterozygosity on cerebral metabolism, in mice, using (14) C-2-deoxyglucose imaging. We also assess performance in an olfactory-based discrimination and reversal learning (OB-DaRL) task and locomotor activity. We use decision tree classifiers to test the predictive relationship between cerebral metabolism and Nrxn1 genotype. Our data show that Nrxn1 heterozygosity induces prefrontal cortex (medial prelimbic cortex, mPrL) hypometabolism and a contrasting dorsal raphé nucleus (DRN) hypermetabolism. Metabolism in these regions allows for the predictive classification of Nrxn1 genotype. Consistent with reduced mPrL glucose utilization, prefrontal cortex insulin receptor signaling is decreased in Nrxn1 (+/-) mice. Behaviorally, Nrxn1 (+/-) mice show enhanced learning of a novel discrimination, impaired reversal learning and an increased latency to make correct choices. In addition, male Nrxn1 (+/-) mice show hyperlocomotor activity. Correlative analysis suggests that mPrL hypometabolism contributes to the enhanced novel odor discrimination seen in Nrxn1 (+/-) mice, while DRN hypermetabolism contributes to their increased latency in making correct choices. The data show that Nrxn1 heterozygosity impacts on prefrontal cortex and serotonin system function, which contribute to the cognitive alterations seen in these animals. The data suggest that Nrxn1 (+/-) mice provide a translational model for the cognitive and behavioral alterations seen in autism and other neurodevelopmental disorders associated with 2p16.3 deletion. LAY SUMMARY: Deletion of the chromosomal region 2p16.3, involving reduced NEUREXIN1 gene expression, dramatically increases the risk of developing autism. Here, we show that reduced Neurexin1 expression, in mice, impacts on the prefrontal cortex and impairs cognitive flexibility. The data suggest that 2p16.3 deletion increases the risk of developing autism by impacting on the prefrontal cortex. Mice with the deletion are a useful model for testing new drugs to treat the cognitive flexibility problems experienced by people with autism.

Atypical neural variability in carriers of 16p11.2 copy number variants / Reem AL-JAWAHIRI in Autism Research, 12-9 (September 2019)  

Public ISBD [article]  inAutism Research > 12-9 (September 2019) . - p.1322-1333 Titre : Atypical neural variability in carriers of 16p11.2 copy number variants Type de document : texte imprimé Auteurs : Reem AL-JAWAHIRI, Auteur ; Myles JONES, Auteur ; Elizabeth MILNE, Auteur Article en page(s) : p.1322-1333 Langues : Anglais (eng) Mots-clés : alpha rhythm  cognitive neuroscience  copy number variation/copy number variants  electroencephalography  event-related potentials  gene-dosage effect  genetic/genomic syndromes Index. décimale : PER Périodiques Résumé : Copy number variations (CNVs) at the 16p11.2 chromosomal region are associated with myriad clinical features including intellectual disability and autism spectrum disorder. The aim of this study is to determine whether 16p11.2 deletion (DEL) and duplication (DUP) carriers demonstrate a distinct and reciprocal pattern of electroencephalography (EEG) activity as represented by neural variability measures. EEG data were previously collected as part of the Simons Variation in Individuals Project. Variability measures, as estimated by single-trial ERP and spectral power analyses in the alpha and beta frequency bands, in addition to signal-to-noise ratios (SNRs), were analyzed in DEL (n = 20), DUP (n = 8), and typical (n = 11) groups. We also analyzed mean visual evoked potentials and spectral power (alpha and beta power) to facilitate comparisons with other studies of associated disorders and CNVs. From measures of single-trial variability, we found higher intraparticipant variability in P1 amplitude and timecourse amplitude in DEL compared to controls. Compared to DUP, DEL showed higher variability in absolute alpha and absolute beta power but lower variability in P1 latency. SNRs did not differ between the groups. From measures of amplitude, latency, and spectral power, DUP showed lower relative alpha power compared to controls. Although it is yet unclear whether 16p11.2 CNV dosage impacts neural activity in an opposing manner, findings suggest that 16p11.2 DEL impacts the level of variability of neural responses. Higher neural variability may play a role in a range of cognitive processes in 16p11.2 CNV carriers. Autism Res 2019, 12: 1322-1333. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The study analyzed the consistency of patterns of brain waves and rhythms in those affected with a loss or gain of DNA material in the 16p11.2 region. Compared with typical individuals, 16p11.2 deletion carriers showed greater inconsistency in the way the brain responds to the same visual event. This high inconsistency in brain activity may play a role in some core symptoms in 16p11.2 copy number variation carriers.

Aberrant oscillatory activity in neurofibromatosis type 1: an EEG study of resting state and working memory / Samantha J. BOOTH in Journal of Neurodevelopmental Disorders, 15 (2023)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 15 (2023) Titre : Aberrant oscillatory activity in neurofibromatosis type 1: an EEG study of resting state and working memory Type de document : texte imprimé Auteurs : Samantha J. BOOTH, Auteur ; Shruti GARG, Auteur ; Laura J.E. BROWN, Auteur ; Jonathan GREEN, Auteur ; Gorana POBRIC, Auteur ; Jason R. TAYLOR, Auteur Langues : Anglais (eng) Mots-clés : Adolescent  Female  Humans  Cognition  Cognitive Dysfunction/etiology  Electroencephalography  Memory, Short-Term  Neurofibromatosis 1/complications  Male  Electroencephalography (EEG)  Neurofibromatosis type 1 (NF1)  Oscillations  Oscillatory power  Phase coherence  Working memory Index. décimale : PER Périodiques Résumé : BACKGROUND: Neurofibromatosis type 1 (NF1) is a genetic neurodevelopmental disorder commonly associated with impaired cognitive function. Despite the well-explored functional roles of neural oscillations in neurotypical populations, only a limited number of studies have investigated oscillatory activity in the NF1 population. METHODS: We compared oscillatory spectral power and theta phase coherence in a paediatric sample with NF1 (N = 16; mean age: 13.03 years; female: n = 7) to an age/sex-matched typically developing control group (N = 16; mean age: 13.34 years; female: n = 7) using electroencephalography measured during rest and during working memory task performance. RESULTS: Relative to typically developing children, the NF1 group displayed higher resting state slow wave power and a lower peak alpha frequency. Moreover, higher theta power and frontoparietal theta phase coherence were observed in the NF1 group during working memory task performance, but these differences disappeared when controlling for baseline (resting state) activity. CONCLUSIONS: Overall, results suggest that NF1 is characterised by aberrant resting state oscillatory activity that may contribute towards the cognitive impairments experienced in this population.

Acceptance and commitment therapy for autistic adults: A randomized controlled pilot study in a psychiatric outpatient setting / Johan PAHNKE in Autism, 27-5 (July 2023)  

Public ISBD [article]  inAutism > 27-5 (July 2023) . - p.1461-1476 Titre : Acceptance and commitment therapy for autistic adults: A randomized controlled pilot study in a psychiatric outpatient setting Type de document : texte imprimé Auteurs : Johan PAHNKE, Auteur ; Markus JANSSON-FRÖJMARK, Auteur ; Gerhard ANDERSSON, Auteur ; Johan BJUREBERG, Auteur ; Jussi JOKINEN, Auteur ; Benjamin BOHMAN, Auteur ; Tobias LUNDGREN, Auteur Article en page(s) : p.1461-1476 Langues : Anglais (eng) Mots-clés : acceptance and commitment therapy;anxiety;autism;cognitive defusion;depression;interventions-psychosocial/behavioral;mindfulness;psychological flexibility;quality of life;stress Index. décimale : PER Périodiques Résumé : Autistic adults are at risk of stress-related psychiatric disorders and reduced life quality due to social, cognitive, and perceptual challenges. Mental health interventions adapted to autistic adults are scarce. Acceptance and commitment therapy has preliminarily indicated health benefits in autistic adults, although it has not been robustly evaluated. Overall, 39 adults (21 males; 21-72 years) with autism spectrum disorder and normal intellectual ability (IQ M 108.5; SD 13.5) were randomized to 14 weeks of adapted acceptance and commitment therapy group treatment (NeuroACT) or treatment as usual. The intervention was feasible. Perceived stress and quality of life (primary outcomes), alongside psychological inflexibility, cognitive fusion, cognitive and behavioral avoidance, and autistic mannerism were statistically significantly improved in NeuroACT compared with treatment as usual (d 0.70-0.90). Clinically significant changes in perceived stress and quality of life were in favor of NeuroACT. Between-group altered depression, anxiety, sleep problems, one quality of life measure, functional impairment, social aspects of autism, and executive difficulties were statistically non-significant. Dropout was slightly higher in NeuroACT. NeuroACT may be a promising treatment for autistic adults with co-existing stress and reduced quality of life. More extensive studies are warranted to evaluate NeuroACT further. Lay abstract Autistic adults are often stressed and feel depressed or anxious. However, mental health programs that are suited for autistic adults are few. Acceptance and commitment therapy is a psychotherapy method that seems to help people feel better, although not thoroughly evaluated in autistic individuals. In this study, 20 autistic adults had 14 weeks of acceptance and commitment therapy group treatment suited for autism (NeuroACT), while 19 autistic adults had ordinary care. The acceptance and commitment therapy group treatment program seemed logical and reasonable to the participants. Also, when comparing the participants in the NeuroACT group with those in the ordinary care group, the NeuroACT participants reported less stress and higher quality of life. Compared to the ordinary care group, they could also manage distressing thoughts better, perceived themselves as more flexible, and did not avoid stressful situations as much as before. However, there was no significant difference between the groups in depression, anxiety, sleep problems, social aspects of autism, everyday functioning, or executive challenges. Slightly more NeuroACT participants did not finish the treatment than ordinary care participants. In conclusion, the NeuroACT program may be a treatment for autistic adults who feel stressed and have reduced quality of life. More studies are needed to see how helpful the NeuroACT program is for autistic adults.
