A new study has revealed that the COVID-19 pandemic had a devastating impact on urban, racial, and ethnic minority children aged five to 11 years old. The research found increased rates of depression and anxiety problems among these children compared to before the pandemic, with rates rising from 5 percent to 18 percent.

A new study found that Pediatric Mental Health Care Access (PMHCA) programs increased referrals from primary care providers to these programs, particularly for patients with mood and anxiety symptoms. PMHCA programs provide training, consultation, and resource-referral support to PCPs, increasing children's access to mental health care.
Researchers found that participants with moderate dementia performed better in cluttered environments, while those with mild and severe dementia showed no significant difference. The study suggests that adapting physical environments to suit individual needs may be more effective than de-cluttering in supporting people with dementia.
A large-scale study of over 3,100 ECT sessions found no cases of permanent impairment, only three life-threatening events that were resolved with medical interventions. The researchers argue that ECT should be used in controlled settings by experienced teams to benefit more patients.
A new study led by scientists at Mount Sinai highlights the role of rare genomic differences in obsessive-compulsive disorder (OCD) risk. The research found that about 10% of the risk for OCD is attributed to rare genomic variations, which were not seen in previous studies.

The study found the parent-led test to be feasible, reliable, and effective in both English and Spanish-speaking groups.
A large study of UK patients found a significant association between SARS-CoV-2 infection and subsequent psychiatric illness, fatigue, and sleep problems. The research used health records of over 12 million patients to examine the relationship between COVID-19 and mental health issues.
A 13-year study tracked the mental health of new doctors during their most stressful time, showing a significant reduction in depression scores over the past decade. The study suggests that reduced work hours, increased sleep, more feedback from supervisors, and greater use of mental health care contributed to this change.
Researchers found a link between the width of growth marks on baby teeth and exposure to early-life adversity, including maternal stress and anxiety. The study's results could lead to the development of a tool to identify children at risk for mental health disorders, allowing for preventive treatments.
The study found that 'general psychiatric burden', 'social isolation', and 'depression/anxiety' worsened during the pandemic, with women more likely to be affected. Factors such as job type, income, and social connections played a significant role in these issues.
The MC3 program provides a lifeline for primary care providers in Michigan, connecting them with psychiatrists and behavioral specialists for consultation and training. This has led to improved diagnosis and care for young people with mental health concerns, including those who express suicidal thoughts or have harmed themselves.
The November issues of The American Journal of Psychiatry and Psychiatric Services address adversity, trauma, and suicide, highlighting the importance of resilience and susceptibility. The journals feature research reports on mental health services delivery for people with serious mental illness.

Researchers at University of California San Diego School of Medicine identified the anterior insula's role in predicting and emotionally processing pain in HIV-DSP patients. The study suggests that reduced anterior insula activity or increased cingulate activity may improve pain outcomes for these patients.
A prospective-longitudinal study found that pregnant women with lower emotional stability and personality traits tend to have worse subjective birth experiences. Unexpected events like Caesareans can exacerbate these negative experiences.
A new machine learning-based algorithm has been developed to identify adolescents who have experienced suicidal thoughts and behavior. The algorithm, applied to a large dataset of survey responses from over 179,000 high school students in Utah, shows high accuracy in predicting individual adolescents at risk.
Longitudinal study reveals cortical thinning in people with bipolar disorder, especially those with more manic episodes. The findings suggest that bipolar disorder may be a neuroprogressive disorder, worsened by the progression of symptoms.
A systematic review of youth helplines found that while they appear to be beneficial, there is limited evidence on their effectiveness, particularly for lower socioeconomic backgrounds. The study highlights the need for further research and tailored services to address systemic barriers to help-seeking.
A nationwide US population-level study found that prior poor mental health at the county level had a positive and significant association with COVID-19 infection rates. Areas with greater vulnerability in poor mental health prior to the pandemic had a greater burden of COVID-19. The study used aggregated survey data from 2,839 US count...
Researchers at Mount Sinai found that people used forward thinking when trying to influence others, regardless of controllability. This neural activity was linked to the ventromedial prefrontal cortex, a decision-making center involved in strategic thinking.
A review of current literature found irregular brain responses to challenging tasks and mistakes may be key to understanding links between abnormal behaviors in mental illness and cognitive disorders. Studies suggest that people with conditions like anxiety, OCD, and ADHD have different brain waves following mistakes compared to health...
A study found that adults with a history of childhood maltreatment, particularly sexual abuse, exhibit reduced brain connectivity in attention systems. Oxytocin treatment has been shown to increase connectivity, suggesting its potential as a treatment for PTSD and childhood trauma-related disorders.
A new register study at Umea University found that people with psychotic or bipolar disorders are significantly more likely to die from influenza, pneumonia, or sepsis. The proportion of deaths due to these conditions was sixfold in certain age groups, highlighting the need for preventive measures.
Research identified a deficit in activation of positive valence processing soon after trauma, suggesting its role in resilience to PTSD. The study found that decreased activity in the ventral striatum predicted more severe PTSD symptoms at 14 months.
A new study found that COVID-19 can trigger severe psychiatric symptoms in adolescents, with anti-neural antibodies playing a potential role. Two patients with mild/asymptomatic COVID developed suicidal thoughts and paranoid fears, while another patient without prior psychiatric history recovered fully after treatment.
Researchers investigated whether continued magnetic seizure therapy (MST) could effectively prevent the relapse of treatment-resistant depression. The study found that MST was associated with a lower relapse rate compared to earlier research assessing one-time, acute MST.

Researchers used machine learning on UK Biobank data to create proxy measures for brain age, intelligence, and neuroticism traits. These indirect measurements strongly correlate with specific diseases or outcomes, offering a potential solution for mental health diagnoses.
A study published in Nature Communications demonstrates how the brain constructs the present moment through recent past experiences. The researchers discovered that brief stimuli leave a trace in the brain for almost a minute, accumulating biases in perception that allow subjects to fine-tune their sensory channels over time.
