Racial and ethnic disparities are also evident, with Black, Hispanic, and Asian adults facing higher odds of certain conditions.
A large observational study found that children conceived through assisted reproductive techniques (ART) have generally good mental health throughout adolescence and young adulthood. However, those born after ART had a slightly elevated risk of obsessive-compulsive disorder, which was explained by parental background factors.

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.

The research examined over 226,000 Ontario inpatient records and found a significant association between age, risk of falls, physical disability, and psychiatric symptoms...
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.
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.
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 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 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.
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.
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.
A UC Davis MIND Institute study suggests telehealth evaluation can help families access care and diagnose autism earlier. The research found that telehealth approaches in the first year of life improved access to care for infants with elevated autism risk, reducing waitlists and parental stress.
Researchers found four distinct brain activity profiles in trauma survivors that correlated with symptoms of anxiety and PTSD six months later. High reward reactivity was linked to increased symptoms of both conditions.
Researchers have identified that moment-to-moment brain signal variability can reliably predict the effectiveness of cognitive behavioural therapy for patients with social anxiety disorder. This finding suggests that neural variability may be a reliable indicator of individual differences in treatment response, particularly when using ...
New research highlights the potential of telehealth to increase patient engagement through improved access and convenience. However, studies found limited evidence that telehealth results in better retention or outcomes compared to in-person treatment. Researchers emphasize the need for more empirical work to confirm its benefits.

The results highlight the importance of timely treatment and rehabilitation to prevent social exclusion.
Researchers from UvA's Centre for Urban Mental Health propose a new conceptual framework to understand the dynamic interplay between urban factors and mental health.
