Perinatal hardship and infant neurodevelopment
BACKGROUND: Material and emotional hardship during pregnancy can shape early brain development and behavior in infants. This study used the COVID-19 pandemic as a natural context in which such hardships were widespread, particularly in low-resource settings. METHODS: This cohort study examined associations between pandemic-related maternal emotional distress and material hardship during pregnancy and early neurodevelopmental outcomes in infants. …
Food choice and neural reward systems in adolescents with anorexia nervosa and atypical anorexia nervosa
BACKGROUND: Adolescence is a critical developmental period for the study of anorexia nervosa (AN), an illness characterized by extreme restriction of food intake. The maturation of the reward system during adolescence combined with recent neurobiological models of AN led to the hypothesis that early on in illness, restrictive food choices would be associated with activity in nucleus accumbens reward regions, rather than caudate regions identified…
Maternal age at birth and child attention‐deficit hyperactivity disorder
BACKGROUND: Causal explanations for the association of young motherhood with increased risk for child attention-deficit hyperactivity disorder (ADHD) remain unclear. METHODS: The ABCD Study recruited 11,878 youth from 22 sites across the United States between June 1, 2016 and October 15, 2018. This cross-sectional analysis of 8,514 children aged 8-11 years excluded 2,260 twins/triplets, 265 adopted children, and 839 younger siblings. We examined …
Effects of Covid-19 Financial and Social Hardships on Infants’ and Toddlers’ Development in the Echo Program
Negative developmental changes from pre- to during-pandemic were found in boys, yet we did not find any associations between increased experience of pandemic-related hardships and children's development. E how pandemic hardships affect development using a larger sample size and with longer follow-up is warranted
Causal effects of psychostimulants on neural connectivity
BACKGROUND: Psychostimulants are frequently used to treat attention-deficit/hyperactivity disorder (ADHD), but side effects are common leading to many patients discontinuing treatment. Identifying neural mechanisms by which psychostimulants attenuate symptoms may guide the development of more refined and tolerable therapeutics. METHODS: We conducted a 12-week, randomized, placebo-controlled trial (RCT) of a long-acting amphetamine, lisdexamfetami…
ADHD and risk for subsequent adverse childhood experiences
BACKGROUND: Children with adverse childhood experiences (ACEs) are more likely to develop Attention-Deficit/Hyperactivity Disorder (ADHD). The reverse relationship - ADHD predicting subsequent ACEs - is vastly understudied, although it may be of great relevance to underserved populations highly exposed to ACEs. METHODS: Participants were 5- to 15-year-olds (48% females) with (9.9%) and without ADHD (DSM-IV criteria except age of onset) in a longi…
Attention-deficit hyperactivity disorder
Neural systems subserving valence and arousal during the experience of induced emotions
The circumplex model of affect construes all emotions as linear combinations of 2 independent neurophysiological dimensions, valence and arousal. We used functional magnetic resonance imaging to identify the neural networks subserving valence and arousal, and we assessed, in 10 participants, the associations of the BOLD (blood oxygen level-dependent) response, an indirect index of neural activity, with ratings of valence and arousal during the em…
