Despite December's historically low suicide rates, some news accounts incorrectly link the holidays to increases in suicides, APPC data find.

A new study of 2,000 U.S. adults shows dark web users report much higher rates of depression, paranoia, suicidal thoughts, self-injury and digital self-harm than surface web users. People with suicidal thoughts were nearly three times more likely to use the dark web, while those engaging in self-injury or digital self-harm were up to five and 19 times more likely, respectively. Researchers suggest dark web use may reflect underlying mental health struggles and urge professionals to reach vulnerable users in these hidden spaces.

Victims of intimate partner violence with suicidal behavior have characteristic injury patterns on medical imaging, according to a new study being presented today at the annual meeting of the Radiological Society of North America (RSNA). The findings open the door to improved screening and earlier intervention to better protect these vulnerable populations, the researchers said.

Half of people who die by suicide have no diagnosed psychiatric risk factors, such as depression. It was unclear whether this population was depressed and undiagnosed, or simply not depressed. Genetic research shows that this population is less likely to have genetic risk factors for depression, suggesting that what puts them at risk is meaningfully different.

Major depressive disorder (MDD) is characterized by a lowered mood and loss of interest, contributing not only to difficulties in academic and professional life but also as a major cause of suicide in South Korea. However, there are currently no objective biological markers that can be used for diagnosis or treatment. Amidst this, a research team from KAIST has revealed that depression is not merely a problem of the mind or brain, but is deeply connected to abnormalities in the body's overall immune response. They found that this immune abnormality affects brain function, and the 'Immune Neural Axis' imbalance is the core mechanism of depression, opening up the possibility for the discovery of new biomarkers and the development of new drugs for depression treatment.
