Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-1 (January 2021) . - p.58-65 Titre : Association between family history of suicide attempt and neurocognitive functioning in community youth Type de document : texte imprimé Auteurs : Jason D. JONES, Auteur ; Rhonda C. BOYD, Auteur ; Monica E. CALKINS, Auteur ; Tyler M. MOORE, Auteur ; Annisa AHMED, Auteur ; Ran BARZILAY, Auteur ; Tami D. BENTON, Auteur ; Raquel E. GUR, Auteur ; Ruben C. GUR, Auteur Article en page(s) : p.58-65 Langues : Anglais (eng) Mots-clés : Family history  cognition  endophenotype  suicide Index. décimale : PER Périodiques Résumé : BACKGROUND: Suicidal behavior is highly familial. Neurocognitive deficits have been proposed as an endophenotype for suicide risk that may contribute to the familial transmission of suicide. Yet, there is a lack of research on the neurocognitive functioning of first-degree biological relatives of suicide attempters. The aim of the present study is to conduct the largest investigation to date of neurocognitive functioning in community youth with a family history of a fatal or nonfatal suicide attempt (FH). METHODS: Participants aged 8-21 years from the Philadelphia Neurodevelopmental Cohort completed detailed clinical and neurocognitive evaluations. A subsample of 501 participants with a FH was matched to a comparison group of 3,006 participants without a family history of suicide attempt (no-FH) on age, sex, race, and lifetime depression. RESULTS: After adjusting for multiple comparisons and including relevant clinical and demographic covariates, youth with a FH had significantly lower executive function factor scores (F[1,3432] = 6.63, p = .010) and performed worse on individual tests of attention (F[1,3382] = 7.08, p = .008) and language reasoning (F[1,3387] = 5.12, p = .024) than no-FH youth. CONCLUSIONS: Youth with a FH show small differences in executive function, attention, and language reasoning compared to youth without a FH. Further research is warranted to investigate neurocognitive functioning as an endophenotype for suicide risk. Implications for the prevention and treatment of suicidal behaviors are discussed.

Mesenchymal Stem Cell Transplantation Promotes Neurogenesis and Ameliorates Autism Related Behaviors in BTBR Mice / Hadar SEGAL-GAVISH in Autism Research, 9-1 (January 2016)  

Public ISBD [article]  inAutism Research > 9-1 (January 2016) . - p.17-32 Titre : Mesenchymal Stem Cell Transplantation Promotes Neurogenesis and Ameliorates Autism Related Behaviors in BTBR Mice Type de document : texte imprimé Auteurs : Hadar SEGAL-GAVISH, Auteur ; Golan KARVAT, Auteur ; Noy BARAK, Auteur ; Ran BARZILAY, Auteur ; Javier GANZ, Auteur ; Liat EDRY, Auteur ; Israel AHARONY, Auteur ; Daniel OFFEN, Auteur ; Tali KIMCHI, Auteur Article en page(s) : p.17-32 Langues : Anglais (eng) Mots-clés : BTBR  animal model  MSC  BDNF  neurogenesis Index. décimale : PER Périodiques Résumé : Autism spectrum disorders (ASD) are characterized by social communication deficits, cognitive rigidity, and repetitive stereotyped behaviors. Mesenchymal stem cells (MSC) have a paracrine regenerative effect, and were speculated to be a potential therapy for ASD. The BTBR inbred mouse strain is a commonly used model of ASD as it demonstrates robust behavioral deficits consistent with the diagnostic criteria for ASD. BTBR mice also exhibit decreased brain-derived neurotrophic factor (BDNF) signaling and reduced hippocampal neurogenesis. In the current study, we evaluated the behavioral and molecular effects of intracerebroventricular MSC transplantation in BTBR mice. Transplantation of MSC resulted in a reduction of stereotypical behaviors, a decrease in cognitive rigidity and an improvement in social behavior. Tissue analysis revealed elevated BDNF protein levels in the hippocampus accompanied by increased hippocampal neurogenesis in the MSC-transplanted mice compared with sham treated mice. This might indicate a possible mechanism underpinning the behavioral improvement. Our study suggests a novel therapeutic approach which may be translatable to ASD patients in the future.

Sex Differences in Psychopathology and Neurocognition in Community Youth With Autism Spectrum Disorder / Ran BARZILAY in Autism Research, 19-8 (August 2026)  

Public ISBD [article]  inAutism Research > 19-8 (August 2026) . - p.e70270 Titre : Sex Differences in Psychopathology and Neurocognition in Community Youth With Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Ran BARZILAY, Auteur ; Julia KATZ, Auteur ; Rahul SOOD, Auteur ; Tyler M.

GUR, Auteur Article en page(s) : p.e70270 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  neurocognition  psychopathology  sex differences  social cognition Index. décimale : PER Périodiques Résumé : ABSTRACT Autism spectrum disorder (ASD) diagnosis is more common in males than females. To understand sex differences in psychopathology and neurocognitive performance, research systematically comparing males and females with autism spectrum disorder to non-autistic peers is critically needed. We examined sex differences in psychopathology and neurocognitive performance profiles in ASD and typically developing youths from the Philadelphia Neurodevelopment Cohort (PNC), a U.S. community sample ascertained through pediatric (non-mental-health) network. We studied 218 youths with ASD diagnosis (IQ>?70, 171 males, 47 females, mean age 12.3?years), age and sex matched to 872 Non-ASD controls. We compared psychopathology in multiple domains including mood-anxiety, fear (phobias), externalizing and psychosis spectrum symptoms as well as neurocognitive function comparing Social and Non-Social cognitive domains. Repeated-measures mixed models were applied with ASD, sex, and their interaction as fixed factors, and psychopathology and neurocognitive domains as within-group factors. All models controlled for age, socioeconomic status, IQ, and ADHD. Findings indicated sex differences in the associations between ASD and co-occurring psychopathology. Among adolescents with ASD, males exhibited more pronounced fear and mood symptoms than females. Analyses also revealed ASD-related sex differences across neurocognitive domains: performance in Social Cognition was lower in adolescents with ASD compared to non-ASD peers for both sexes, while males with ASD showed greater difficulties in Non-Social Cognition relative to females with ASD. In conclusion, ASD diagnosis is associated with sex differences in psychopathology and neurocognition in early adolescence in a large community sample. Results add to the understanding of sex-specific manifestations of ASD in youth.
