Objectives Undergraduate and graduate students have reported rising rates of anxiety that were exacerbated by the COVID-19 pandemic, possibly related to heightened intolerance of uncertainty. The present preregistered pilot study investigated whether psychoeducational wellness programs based on behavioral activation or mindfulness were associated w...
Article
Objective: Preclinical work suggests that excess glucocorticoids and reduced cortical γ-aminobutyric acid (GABA) may affect sex-dependent differences in brain regions implicated in stress regulation and depressive phenotypes. The authors sought to address a critical gap in knowledge, namely, how stress circuitry is functionally affected by glucoco...

Predicting mood disorders in adolescence is a challenge that motivates research to identify neurocognitive predictors of symptom expression and clinical profiles. This study used machine learning to test whether neurocognitive variables predicted future manic or anhedonic symptoms in two adolescent samples risk-enriched for lifetime mood disorders...
Article
Background Interest in the potential mental health effects of cannabidiol (CBD) has increased recently, with a surge in commercial and pharmaceutical development of CBD products and a concomitant rise in consumer use. However, despite the widespread and growing use of CBD products by adults and adolescents, the mental health effects of CBD remain l...
Article
Increase in stress-related disorders in women begins post-puberty and persists throughout the lifespan. To characterize sex differences in stress response in early adulthood, we used functional magnetic resonance imaging while participants underwent a stress task in conjunction with serum cortisol levels and questionnaires assessing anxiety and moo...

Background Maladaptive and adaptive emotion regulation are putative risk and protective factors for depression and anxiety, but most prior research does not differentiate within-person effects from between-person individual differences. The current study does so during the early part of the Covid-19 pandemic when internalizing symptoms were high....
Article
Background: Life stressors confer risk for depressive symptoms, but individuals vary in the extent of their sensitivity to life stressors. One protective factor may be an individual's level of reward sensitivity, e.g., a stronger neurobiological response to environmental rewards may mitigate emotional responses to stressors. However, the nature of...
Article
Adolescence is a critical period of neurocognitive development and increased prevalence of mood pathology. In this cross-sectional study, we replicated developmental patterns of neurocognition and tested whether mood symptoms moderated developmental effects. Participants were 419 adolescents ( n = 246 with current mood disorders) who completed rewa...
Article
The interplay between cortical and limbic regions in stress circuitry calls for a neural systems approach to investigations of acute stress responses in major depressive disorder (MDD). Advances in multimodal imaging allow inferences between regional neurotransmitter function and activation in circuits linked to MDD, which could inform treatment de...
Article
In this direct replication of Mueller and Oppenheimer's (2014) Study 1, participants watched a lecture while taking notes with a laptop (n = 74) or longhand (n = 68). After a brief distraction and without the opportunity to study, they took a quiz. As in the original study, laptop participants took notes containing more words spoken verbatim by the...

Purpose Gamma‐aminobutyric acid (GABA) abnormalities have been implicated in a range of neuropsychiatric disorders. Despite substantial interest in probing GABA in vivo, human imaging studies relying on magnetic resonance spectroscopy (MRS) have generally been hindered by technical challenges, including GABA’s relatively low concentration and spect...

There is a known negative association between cytosine–adenine–guanine (CAG) repeat length and the age of motor onset (AMO) in adult-onset Huntington’s Disease (AOHD). This relationship is less clear in patients with juvenile-onset Huntington’s disease (JOHD), however, given the rarity of this patient population. The aim of this study was to invest...
Article
Research on the feasibility of using transcranial direct current stimulation to modulate the function of the anterior cingulate cortex is limited in part due to its anatomical depth. However, high-definition transcranial direct current stimulation may be better able to reach the anterior cingulate cortex and modulate its function and behavioral out...
Article
Background: Correlates of cannabis use and dependence among young adults have been widely studied. However, it is not known which factors are most strongly associated with severity of cannabis use dependence (CUD) severity. Identification of the salient correlates of CUD severity will be of increasing clinical significance as use becomes more soci...

Aim: The symptoms of Huntington's disease are well known, yet the symptoms of juvenile Huntington's disease (JHD) are less established due to its rarity. The study examined a cluster of symptoms considered to be common, but under-recognized in JHD: pain, itching, sleeping difficulties, psychosis and tics. Materials & methods: A symptom survey wa...
Article
Background JHD is ultra-rare (5–10% of all HD) and therefore our knowledge about it is spotty with most information coming from clinical experience or case series. Social media has allowed communities of JHD families to communicate regularly. Through this mechanism, we identified 5 symptoms that were often mentioned by JHD caretakers, but were not...
