Adding to a growing body of research on mental health and the human microbiome, a new study compared the bacteria in the saliva of students with and without recent thoughts of suicide, called suicidal ideation.

More than 70 percent of packaged foods in the U.S. are classified as ultra-processed food and represent about 60 percent of all calories consumed by Americans. A study in 10,359 adults 18 and older found those who consumed the most ultra-processed foods as compared with those who consumed the least amount had statistically significant increases in the adverse mental health symptoms of mild depression, 'mentally unhealthy days' and 'anxious days.' They also had significantly lower rates of reporting zero 'mentally unhealthy days' and zero 'anxious days.' Findings are generalizable to the entire U.S. as well as other Western countries with similar ultra-processed food intakes.

The passage of time was altered for many people during the COVID-19 pandemic, ranging from difficulty in keeping track of days of the week to feeling that the hours themselves rushed by or slowed down. In prior work, these distortions have been associated with persistent negative mental outcomes such as depression and anxiety following trauma, making them an important risk factor to target with early interventions, according to a new study.

New study suggests that a 'blended' eight-week mindfulness program that adds Team Mindfulness Training (TMT) to a shortened version of the mindfulness-based stress reduction (MBSR) course for individual mindfulness is just as effective as the standard MBSR course alone. It may even offer further benefit by increasing collective stress management skills.

A new study found that the medication combination glecaprevir and pibrentasvir had the strongest association with PTSD symptom improvement among the DAAs most prescribed in the VA.

Deep brain stimulation (DBS) to the superolateral branch of the medial forebrain bundle (MFB), which is linked to reward and motivation, revealed metabolic brain changes over 12 months post-DBS implantation, making it a strong potential therapy for treatment-resistant depression according to researchers.

Screening for depression at the primary care level could dramatically increase the likelihood of treatment for those who are traditionally undertreated -- racial and ethnic minority individuals, older adults, those with limited English proficiency and men -- according to a new study.

Among children born at term (37--41 weeks), those born before 39 weeks are more likely to experience symptoms associated with attention-deficit/hyperactivity disorder (ADHD), according to a new study.

An extensive meta-analysis suggests that vitamin D supplementation may alleviate depressive symptoms in adults with depression. Conducted by an international team of researchers, the meta-analysis includes dozens of studies from around the world.

Researchers have discovered that the electrical stimulation of the eye surface can alleviate depression-like symptoms and improve cognitive function in animal models.
