This finding is linked to increased need for stimulation, impulsive behaviors, and higher likelihood of violent behavior.
Rates of postpartum depression symptoms increased nationwide during the pandemic, reaching a high of 7.7% in December 2020 to March 2021. States with fewer COVID-19 deaths and lower unemployment rates showed greater increases in symptoms, likely due to reduced access to support systems.
A machine-learning model developed by researchers at Massachusetts General Hospital predicts which US Army soldiers are at greatest risk of homelessness upon transitioning to civilian life. The study identifies lifetime depression, trauma, and PTSD as key predictors, allowing for targeted interventions to mitigate homelessness.
Researchers developed a new model to understand how delusions emerge and are shaped by different contexts, revealing common themes across patient accounts. Clinicians must go beyond 'correcting' dysfunction to devise treatment that is relevant to the individual's emotions, life experiences, and socio-cultural contexts.
Researchers at the University of South Florida conducted a comprehensive review of data on 25,000 Canadians and found that long-term well-being is a realistic goal for some patients with mental illnesses. The study revealed that symptoms only correlate modestly with well-being, and that earlier treatment may improve outcomes.

A study tracking 425 patients post-COVID-19 found high prevalence of cognitive deficits, psychiatric impairments, and significant memory decline. Researchers observed no correlation between the severity of the disease or socio-economic factors with psychiatric alterations, suggesting a possible link to delayed inflammatory processes.
A recent study found that behavioral treatments can reduce ADHD symptoms and improve behavior in children, but not all children respond equally well. Priority should be given to those with more severe ADHD, conduct disorder symptoms, or from single-parent families, as they are at risk of deterioration without treatment.
A study by the Brazilian High-Risk Cohort Study for Childhood Psychiatric Disorders found an association between child poverty and externalizing disorders in adolescence and early adulthood. Child poverty was particularly harmful to women, increasing their risk of developing mental health problems and affecting educational attainment.
Researchers found lower functional connectivity between brain areas involved in social and emotional processing in individuals at risk of developing alcohol use disorder. This impairment may affect their ability to interpret facial expressions and respond to their environment, increasing the likelihood of disordered drinking.
Markita del Carpio Landry, a young immigrant scientist, receives the Vilcek Prize for Creative Promise for her groundbreaking research on neurochemical communication and gene-editing technologies. Her work aims to address medicine's most compelling problems, including aberrations in neurotransmitter signaling.
