Annual Research Review: Critical windows - the microbiota-gut-brain axis in neurocognitive development / Caitlin S. M. COWAN in Journal of Child Psychology and Psychiatry, 61-3 (March 2020)

As an integral part of the microbiota-gut-brain axis, it is now being recognized that the microbiota is a modulator of brain and behavior, across species. Intriguingly, periods of change in the microbiota coincide with the development of other body systems and particularly the brain. We hypothesize that these times of parallel development are biologically relevant, corresponding to 'sensitive periods' or 'critical windows' in the development of the microbiota-gut-brain axis. Specifically, signals from the microbiota during these periods are hypothesized to be crucial for establishing appropriate communication along the axis throughout the life span. In other words, the microbiota is hypothesized to act like an expected input to calibrate the development of the microbiota-gut-brain axis. The absence or disruption of the microbiota during specific developmental windows would therefore be expected to have a disproportionate effect on specific functions or potentially for regulation of the system as a whole. Evidence for microbial modulation of neurocognitive development and neurodevelopmental risk is discussed in light of this hypothesis, finishing with a focus on the challenges that lay ahead for the future study of the microbiota-gut-brain axis during development.

Obstetrical Mode of Delivery and Childhood Behavior and Psychological Development in a British Cohort / Eileen A. CURRAN in Journal of Autism and Developmental Disorders, 46-2 (February 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-2 (February 2016) . - p.603-614 Titre : Obstetrical Mode of Delivery and Childhood Behavior and Psychological Development in a British Cohort Type de document : Texte imprimé et/ou numérique Auteurs : Eileen A. CURRAN, Auteur ; John F. CRYAN, Auteur ; Louise C. KENNY, Auteur ; Timothy G. DINAN, Auteur ; Patricia M. KEARNEY, Auteur ; Ali S. KHASHAN, Auteur Année de publication : 2016 Article en page(s) : p.603-614 Langues : Anglais (eng) Mots-clés : Naissance  césarienne  Autism spectrum disorder  ADHD  Mode of delivery  Induction of labor Index. décimale : PER Périodiques Résumé : The association between mode of delivery [specifically birth by Cesarean section (CS)] and induction of labor (IOL) psychological development at age 7 was assessed [including autism spectrum disorders (ASD), attention-deficit/hyperactivity disorder (ADHD) and behavioral difficulties]. The Millennium cohort study, a nationally representative UK cohort of children (including 13,141 children), was used. There was no association between planned CS and ASD [aOR 0.58; (95 % CI 0.19–1.79)] or ADHD [aOR 0.54; (95 % CI 0.18–1.64)] analyses. Induced vaginal delivery was significantly associated with behavioral difficulties in unadjusted [OR 1.26; (95 % CI 1.03–1.54)], but not adjusted analysis [OR 1.15; (95 % CI 0.82–1.60)]. There was no association between mode of delivery and ASD or ADHD in this cohort. Further research is needed to understand the relationship between mode of delivery and IOL and psychological development.

Research Review: Birth by caesarean section and development of autism spectrum disorder and attention-deficit/hyperactivity disorder: a systematic review and meta-analysis / Eileen A. CURRAN in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-5 (May 2015) . - p.500-508 Titre : Research Review: Birth by caesarean section and development of autism spectrum disorder and attention-deficit/hyperactivity disorder: a systematic review and meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : Eileen A. CURRAN, Auteur ; Sinéad M. O'NEILL, Auteur ; John F. CRYAN, Auteur ; Louise C. KENNY, Auteur ; Timothy G. DINAN, Auteur ; Ali S. KHASHAN, Auteur ; Patricia M. KEARNEY, Auteur Article en page(s) : p.500-508 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  attention-deficit/hyperactivity disorder  Caesarean section Index. décimale : PER Périodiques Résumé : Background Given the growing prevalence of birth by Caesarean section (CS) worldwide, it is important to understand any long-term effects CS delivery may have on a child's development. We assessed the impact of mode of delivery on autism spectrum disorders (ASD) and attention-deficit/hyperactivity disorder (ADHD). Methods We conducted a systematic review of the literature in PubMed, Embase, CINAHL, PsycINFO and Web of Science up to 28 February 2014. No publication date, language, location or age restrictions were employed. Results Thirteen studies reported an adjusted estimate for CS-ASD, producing a pooled odds ratio (OR) of 1.23 (95% CI: 1.07, 1.40). Two studies reported an adjusted estimate for CS-ADHD, producing a pooled OR of 1.07 (95% CI: 0.86, 1.33). Conclusions Delivery by CS is associated with a modest increased odds of ASD, and possibly ADHD, when compared to vaginal delivery. Although the effect may be due to residual confounding, the current and accelerating rate of CS implies that even a small increase in the odds of disorders, such as ASD or ADHD, may have a large impact on the society as a whole. This warrants further investigation.
