Developmental Model of Depression Applied to Prenatal Depression: Role of Present and Past Life Events, Past Emotional Disorders and Pregnancy Stress

Several risk factors for depression during pregnancy have already been established. However, very few studies have conducted a multivariate analysis incorporating both the major predictors of depression in women, in accordance with comprehensive developmental models of depression, and specific stressors associated with the biological and psychosocial state of the mother-to-be.We used a cross-sectional cohort design to analyze the associations between prenatal depression and potential risk factors. 693 French-speaking women with singleton pregnancies at 20-28 weeks' gestation were consecutively recruited at Caen University Hospital. Fifty women with missing values were subsequently excluded from the analysis. Depressive symptoms were assessed on the Edinburgh Postnatal Depression Scale. Risk factors were either extracted from the computerized obstetric records or assessed by means of self-administered questionnaires. The associations between prenatal depression and the potential risk factors were assessed using log-binomial regression models to obtain a direct estimate of relative risk (RR). The following factors were found to be significant in the multivariate analysis: level of education (p<0.001), past psychiatric history (adjusted RR=1.8, 95% confidence interval (CI): 1.1;2.8, p=0.014), stress related to the health and viability of the fetus (adjusted RR=2.6, 95% CI: 1.6;4.1, p<0.001), and stress related to severe marital conflicts (adjusted RR=2.4, 95% CI: 1.5;3.9, p<0.001) or to serious difficulties at work (adjusted RR=1.6, 95% CI :1.04;2.4, p=0.031). An association was also found with the previous delivery of a child with a major or minor birth defect (adjusted RR=2.0, 95% CI: 1.04;4.0, p=0.038). Univariate analyses revealed a strong association with childhood adversity (parental rejection: RR=1.8, 95% CI: 1.2;2.8, p=0.0055 and family secrets: RR=2.0, 95% CI: 1.2;3.1, p=0.0046) and with lack of partner support (RR=0.50, 95% CI: 0.30;0.84, p=0.0086).Our study identifies several risk factors that could easily be assessed in clinical practice. It draws attention to the impact of previously delivering a child with a birth defect. The association with childhood adversity warrants further study

Impact of Semantic Relatedness on Associative Memory: An ERP Study

Encoding and retrieval processes in memory for pairs of pictures are thought to be influenced by inter-item similarity and by features of individual items. Using Event-Related Potentials (ERP), we aimed to identify how these processes impact on both the early mid-frontal FN400 and the Late Positive Component (LPC) potentials during associative retrieval of pictures. Twenty young adults undertook a sham task, using an incidental encoding of semantically related and unrelated pairs of drawings. At test, we conducted a recognition task in which participants were asked to identify target identical pairs of pictures, which could be semantically related or unrelated, among new and rearranged pairs. We observed semantic (related and unrelated pairs) and condition effects (old, rearranged and new pairs) on the early mid-frontal potential. First, a lower amplitude was shown for identical and rearranged semantically related pairs, which might reflect a retrieval process driven by semantic cues. Second, among semantically unrelated pairs, we found a larger negativity for identical pairs, compared to rearranged and new ones, suggesting additional retrieval processing that focuses on associative information. We also observed an LPC old/new effect with a mid-parietal and a right occipito-parietal topography for semantically related and unrelated old pairs, demonstrating a recollection phenomenon irrespective of the degree of association. These findings suggest that associative recognition using visual stimuli begins at early stages of retrieval, and differs according to the degree of semantic relatedness among items. However, either strategy may ultimately lead to recollection processes

Individualized immunological data for precise classification of OCD patients

Obsessive⁻compulsive disorder (OCD) affects about 2% of the general population, for which several etiological factors were identified. Important among these is immunological dysfunction. This review aims to show how immunology can inform specific etiological factors, and how distinguishing between these etiologies is important from a personalized treatment perspective. We found discrepancies concerning cytokines, raising the hypothesis of specific immunological etiological factors. Antibody studies support the existence of a potential autoimmune etiological factor. Infections may also provoke OCD symptoms, and therefore, could be considered as specific etiological factors with specific immunological impairments. Finally, we underline the importance of distinguishing between different etiological factors since some specific treatments already exist in the context of immunological factors for the improvement of classic treatments

Wechsler profiles in referred children with intellectual giftedness: Associations with trait-anxiety, emotional dysregulation, and heterogeneity of Piaget-like reasoning processes

International audienceBackground/purposeIt is common that intellectually gifted children (IQ ≥ 130) are referred to paediatric or child neuropsychiatry clinics for socio-emotional problems and/or school underachievement or maladjustment. Among them, those displaying developmental asynchrony – a heterogeneous developmental pattern reflected in a significant verbal-performance discrepancy (SVPD) on Wechsler's intelligence profile – are thought to be more emotionally and behaviourally impaired than others. Our purpose was to investigate this clinical dichotomy using a cognitive psychopathological approach.MethodsTrait-anxiety and emotional dysregulation were investigated in two groups of referred gifted children (n = 107 and 136, respectively), a pilot-study of reasoning processes on extensive Piaget-like tasks was also performed in an additional small group (n = 12).ResultsCompared to those with a homogenous Wechsler profile, children with a SVPD exhibited: 1) a decreased prevalence of social preoccupation-anxiety (11.1% versus 27.4%; p < 0.05); 2) an increased prevalence of emotional dysregulation (58.7% versus 41.3%; p < 0.05); and 3) an increased prevalence of pathological cognitive disharmony on Piaget-like tasks (87.5% versus 0.0%; p < 0.05).ConclusionThe results support a clinical dichotomy of behaviourally-impaired children with intellectual giftedness, with developmentally asynchronous ones exhibiting more severe psychopathological features. This suggests that developmental asynchrony matters when examining emotional and behavioural problems in gifted children and call for further investigation of this profile
