Identifying imaging biosmarkers that reflect the prenatal and early childhood origins of cognitive ability, behavior, and risk for neuropsychiatric disorders is now possible, and this commentary offers suggestions for addressing some of the challenges that lie ahead.

Exposure to prenatal maternal distress and infant white matter neurodevelopment / Catherine H. DEMERS in Development and Psychopathology, 33-5 (December 2021)

These rapid neurological advances render the fetus susceptible to various influences with life-long implications for mental health. Maternal distress signals are a dominant early life influence, contributing to birth outcomes and risk for offspring psychopathology. This prospective longitudinal study evaluated the association between prenatal maternal distress and infant white matter microstructure. Participants included a racially and socioeconomically diverse sample of 85 mother–infant dyads. Prenatal distress was assessed at 17 and 29 weeks’ gestational age (GA). Infant structural data were collected via diffusion tensor imaging (DTI) at 42–45 weeks’ postconceptional age. Findings demonstrated that higher prenatal maternal distress at 29 weeks’ GA was associated with increased fractional anisotropy, b = .283, t(64) = 2.319, p = .024, and with increased axial diffusivity, b = .254, t(64) = 2.067, p = .043, within the right anterior cingulate white matter tract. No other significant associations were found with prenatal distress exposure and tract fractional anisotropy or axial diffusivity at 29 weeks’ GA, or earlier in gestation.

Turner syndrome: language profile of young girls at 12 and 24 months of age / Debra B. REINHARTSEN in Journal of Neurodevelopmental Disorders, 13 (2021)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 13 (2021) Titre : Turner syndrome: language profile of young girls at 12 and 24 months of age Type de document : texte imprimé Auteurs : Debra B. REINHARTSEN, Auteur ; Emil CORNEA, Auteur ; Margaret DERAMUS, Auteur ; Angelia B. WAITT, Auteur ; Rebecca Edmondson PRETZEL, Auteur ; Rebecca C. KNICKMEYER, Auteur ; Marsha L. DAVENPORT, Auteur ; John H. GILMORE, Auteur ; Stephen R. HOOPER, Auteur Langues : Anglais (eng) Mots-clés : Child, Preschool  Cognition  Female  Humans  Infant  Language Development  Language Development Disorders/epidemiology  Speech  Turner Syndrome/complications  Expressive language  Infants  Neurodevelopmental disorders  Receptive language  Social language  Symbolic language  Toddlers  Turner syndrome Index. décimale : PER Périodiques Résumé : BACKGROUND: Turner syndrome (TS) is a genetic disorder associated with complete or partial absence of an X chromosome affecting approximately 1/2000 live female births. Available evidence suggests that, in the school-age years, girls with TS often require speech and language services; however, little is known about the language development of infants and toddlers. METHOD: This study (N = 31) explored the language profiles of 12- and 24-month-old girls with TS, as well as the percentage of girls who might be "at risk" for language delays. We also followed a subset of 12-month-old girls with TS to 24 months of age to determine the stability of the 12-month findings. RESULTS: Although all mean scores were within the average range at both time points, results revealed a higher prevalence of 24-month-old girls with TS "at risk" for receptive language difficulties. In addition, expressive language skills significantly exceeded receptive language skills at both time points. We found 12-month-old girls to be "at risk" for social and symbolic difficulties based on clinical assessment; only symbolic difficulties were significant based on caregiver report. At 24 months, clinical assessment indicated greater use of speech sounds and words than normative expectations. Caregivers reported greater use of speech sounds, and also, greater use of gestures. Although some changes occurred over a 1-year time span (12 to 24 months), all mean test scores remained within the average range and the changes in the percentage of girls manifesting "at risk" status on either the PLS-4 or CSBS-DP were non-significant. CONCLUSIONS: Although within normal limits, receptive language skills were found to be significantly lower than expressive language skills at both ages. Social and symbolic communication skills also were in the average range, with both showing significant improvement from 12 to 24 months based on clinical assessment. Caregiver report found that use of gestures and production of speech sounds not only improved from 12 to 24 months, but also exceeded normative expectations. Findings suggest the presence of relatively intact speech and language abilities during the first 2 years of life, with perhaps some emergent concerns for receptive language development. Ongoing developmental surveillance will be important.
