Objective The aim of this study was to characterize the course of ADHD during pregnancy. Method Women ages 18 to 45 were followed prospectively at <20 weeks, 24 weeks, and 36 weeks pregnant. Three groups emerged: women who discontinued, maintained, or adjusted their ADHD medications. ADHD symptoms were recorded using the AISRS. Anxiety, depression, stress, and functional impairment were monitored. Results A total of 25 women with ADHD were eligible for analysis. No significant difference observed between three groups in AISRS scores. Significant differences found between medication discontinuers vs adjusters for both mood and family functioning (EPDS, 5.3, p < .0001; WFIRS, 3.3, p = .0309). Significant differences also found between discontinuers vs maintainers for mood and family functioning (EPDS, 4.98, p = .0009; WFIRS, 3.09, p = .0197). Conclusion This preliminary study provides novel insight into the course of ADHD during pregnancy, underscoring mood and family functioning as critical domains that may contribute to growing use of psychostimulants during pregnancy.

Alopecia is common among captive populations of nonhuman primates. There are many potential causes of alopecia, including physiological conditions such as hormonal imbalance and infection, features of the captive environment such as housing type, ground substrate, and group density, as well as behavioral abnormalities such as self-plucking. A potential behavioral cause of alopecia in group-housed primates is social hair pulling, where one animal pulls hair from a conspecific. While social hair pulling has been conflated with overgrooming in some of the alopecia literature, other authors have categorized it as a form of aggression rather than a form of excessive grooming. In this study we examined social hair pulling, grooming, and aggression within 7 groups of rhesus macaques (Macaca mulatta) (N=319). We took weekly 30-minute behavioral observations on each group for one year to assess the patterns of hair pulling and grooming, which monkeys were receiving and initiating these behaviors, as well as aggression and other behaviors indicating dominance. We also assessed the amount of alopecia on each individual monthly. While grooming tended to be directed “up” the hierarchy (i.e., monkeys were more likely to groom animals of a higher rank than lower rank), most hair pulling was directed “down” the hierarchy. Further, hair pulling seldom co-occurred with aggressive behaviors, suggesting that it was not a form of aggression. Hair pulling also usually resulted in ingestion of the pulled hair. Hair pulling was correlated with alopecia; monkeys who were frequent recipients of hair pulling scored higher on monthly alopecia ratings than those who were less often observed having hair pulled. Our results suggest that social hair pulling is a behavior distinct from either grooming or aggressive behavior, and that it may contribute to alopecia in socially housed macaques.

Women may experience new-onset or worsening depressive disorders during pregnancy and the postpartum. If untreated, there may be detrimental consequences to the health and wellbeing of the woman and to her baby. There is a need for improved tools and approaches that can be easily and broadly implemented to effectively detect depression during the perinatal period. Early identification of depression during pregnancy is an important first step towards connecting women to treatment and preventing continued depression into the postpartum or beyond. This report provides preliminary findings from a pilot study of a digital screening app for perinatal depression expiring potential for app reach, engagement, and user demographics and mental health symptoms. With mainly passive recruitment efforts, we collected cross-sectional mental health data on over 700 women during the perinatal period, including women across over 30 countries. We report on mean depression scores among women during pregnancy and the postpartum as well as on constructs that are commonly comorbid with depression, including anxiety, sleep dysregulation, and perceived stress. Over half of the women during pregnancy and over 70% of women in the postpartum had a depression score indicative of clinical depression. Future research directions for this work and potential for public health impact are discussed, including longitudinal data collection and analyses of symptomology over time and embedding evidence-based digital therapeutics into the app as a means to increase access to mental health services.
