Reduced sensory habituation—the brain’s ability to filter out repetitive, irrelevant stimuli— is commonly found in neurodevelopmental disorders. We found that predictive signals from the orbitofrontal cortex to the primary auditory cortex actively drive this process, providing insights into the neural basis of impaired habituation.

This review examines factors influencing the recurrence of depressive episodes following remission in LLD, focusing on cognitive, behavioral, social, environmental, and neuroimaging influences. It further proposes possible mechanisms contributing to recurrence, including physiological and behavioral responses to stressors, the influence of Alzheimer’s disease neuropathology, and conceptualizing repeat depressive episodes within...

In this pilot randomized controlled trial, our team evaluated the feasibility and preliminary effectiveness of a mobile health (mHealth) intervention for caregivers to youth at risk for psychosis, called Bolster. Results suggested that Bolster was feasible to deliver, acceptable to this population, and demonstrated promising effectiveness in improving family communication,...

This study compared late-perimenopausal women with and without perimenopausal-onset major depressive disorder (PO-MDD) to examine patterns of depression, anxiety, temperament, and menopausal symptoms. Women with PO-MDD showed significantly higher levels of irritability, anxiety, negative temperament, and overall menopausal distress, suggesting that screening for anxiety and related symptoms is important when...

We offer 7 observations regarding use of AI chatbots for mental health and emotional support and 7 desiderata that any ethical framework for monitoring and regulating such chatbots should meet. We then illustrate how these desiderata help in assessing frameworks by using them to assess a recent paper by Serife...

Many women treated for early-stage breast cancer report ongoing problems with memory and thinking years after chemotherapy. In this study, nearly 40% of survivors reported long-term cognitive concerns, and those who experienced depression, anxiety, or fatigue during chemotherapy were significantly more likely to have these difficulties years later—highlighting the importance...

Postpartum depression (PPD) is linked to neuroimmune dysregulation. Brexanolone, an intravenous formulation of the neurosteroid allopregnanolone and the first FDA-approved treatment for PPD, produces rapid and sustained antidepressant effects. However, its long-term mechanisms of action remain unclear. This study evaluated brexanolone’s prolonged impact on two groups of biomarkers in whole...

Posttraumatic stress disorder (PTSD) can develop after experiencing or witnessing a traumatic event, such as an accident or assault. Symptoms can include flashbacks, anxiety, and emotional distress, which significantly impact daily life. This study explores how changes in brain activity after trauma can predict future symptoms of posttraumatic stress (PTS)....
