We agree that our results mesh well with previous work documenting hypocortisolism among youth who experienced early adversity, especially neglect. Moreover, as also perceptively noted by Dr. Fisher, our cross-sectional data provide support for the notion that hypocortisolism is not simply a transient phenomenon, but, rather, a persistent pattern characterizing maltreated youth. Specifically, the consistency of the between group effect (from age 9.69 onwards) on a multimonth index of cumulative cortisol and the dose-dependent gradient of cortisol secretion within the maltreated group, which was related to the number of subtypes and the length of exposure to maltreatment, lend weight to this view.

Methods: General cognitive, phonological and literacy skills were tested in 1,138 control and 1,114 dyslexic children speaking six different languages spanning a large range of orthographic complexity (Finnish, Hungarian, German, Dutch, French, English). Results: Phoneme deletion and RAN were strong concurrent predictors of developmental dyslexia, while verbal ST/WM and general verbal abilities played a comparatively minor role. In logistic regression models, more participants were classified correctly when orthography was more complex. The impact of phoneme deletion and RAN-digits was stronger in complex than in less complex orthographies. Conclusions: Findings are largely consistent with the literature on predictors of dyslexia and literacy skills, while uniquely demonstrating how orthographic complexity exacerbates some symptoms of dyslexia.

Reduced hair cortisol after maltreatment mediates externalizing symptoms in middle childhood and adolescence / Lars O. WHITE in Journal of Child Psychology and Psychiatry, 58-9 (September 2017)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 58-9 (September 2017) . - p.998-1007 Titre : Reduced hair cortisol after maltreatment mediates externalizing symptoms in middle childhood and adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Lars O.

Long-term effects of stress may be reflected in cumulative cortisol secretion over several months, which is now quantifiable via hair cortisol concentrations (HCC). We conducted a first comprehensive investigation utilizing the potential of hair cortisol analysis in a large sample of maltreated and nonmaltreated children and adolescents. Method Participants included 537 children and adolescents (3–16 years; 272 females) with maltreatment (n = 245) or without maltreatment histories (n = 292). Maltreated subjects were recruited from child protection services (CPS; n = 95), youth psychiatric services (n = 56), and the community (n = 94). Maltreatment was coded using the Maltreatment Classification System drawing on caregiver interviews and complemented with CPS records. Caregivers and teachers reported on child mental health. HCC were assessed in the first 3 cm hair segment. Results Analyses uniformly supported that maltreatment coincides with a gradual and dose-dependent reduction in HCC from 9 to 10 years onwards relative to nonmaltreated controls. This pattern emerged consistently from both group comparisons between maltreated and nonmaltreated subjects (27.6% HCC reduction in maltreated 9–16-year-olds) and dimensional analyses within maltreated subjects, with lower HCC related to greater maltreatment chronicity and number of subtypes. Moreover, both group comparisons and dimensional analyses within maltreated youth revealed that relative HCC reduction mediates the effect of maltreatment on externalizing symptoms. Conclusions From middle childhood onwards, maltreatment coincides with a relative reduction in cortisol secretion, which, in turn, may predispose to externalizing symptoms.
