A study of over 12,000 older adults suggests a strong association between environmental factors—like heatwaves and air pollution—and a greater risk of developing depressive symptoms.

A new study challenges the idea that trigger warnings prevent exposure to upsetting content. Most young adults reported viewing the content anyway, including those with past trauma or mental health concerns, raising questions about the real-world impact of these warnings.

Research published in Advanced Science indicates that amyloid plaques associated with Parkinson's disease may act like rogue enzymes, breaking down adenosine triphosphate and draining neurons of the energy they need to survive and function.

A person's inherited risk for inflammation may help predict their response to antidepressants and define a distinct, metabolic form of depression, according to a new study.

When it comes to the mental health benefits of urban green space, a moderate amount is best, a new study concludes. The research in Nature Cities synthesizes decades of data to find the relationship is an inverted U-shape.
