New research suggests that regular physical activity may lower the risk and severity of major depression, particularly among people with a genetic predisposition. ...

By simulating human visual processing with a deep neural network, researchers have discovered a computational marker that predicts an adolescent's risk for developing depression up to four years before symptoms appear.

Santé mentale des collégiens et lycéens en 2024 : le bien-être gagne 11 points au collège et 12 points au lycée depuis 2022, mais 19 % des lycéens présentent un risque de dépression et 20 % ont eu des pensées suicidaires dans l'année, selon Santé publique France.

Background: Digital inclusion has become increasingly important in promoting healthy aging, yet its impact on mental health among older adults appears complex and heterogeneous. While existing research has identified associations between digital technology use and depression risk in older adults, the role of cognitive function as a moderator and the underlying mechanisms remain understudied. Objective: Data from the 2020 wave of the China Health and Retirement Longitudinal Study (CHARLS), a nationally representative survey of 18,673 Chinese adults aged 60 and above. Methods: We examined cognitive function's moderating role in the relationship between digital inclusion and depression risk. We constructed interaction effect models to test the moderation hypothesis and employed path analysis to investigate multiple pathways (direct effect, cognitive enhancement, and social participation) through which digital inclusion influences depression. Results: Cognitive function significantly moderated the relationship between digital inclusion and depression risk (β = -0.002, p < 0.05), with stronger protective effects observed among older adults with higher cognitive function. Path analysis revealed that digital inclusion affected depression through three main pathways: a direct pathway (accounting for 66.7% of the total effect), a cognitive function mediation pathway (8.3%), a social participation mediation pathway (8.0%), and a sequential mediation pathway through cognitive function and social participation (2.8%). The remaining 14.2% was attributed to unexplained mechanisms. Conclusions: Our findings reveal a "cognitive threshold effect," suggesting that older adults require a baseline level of cognitive function to derive mental health benefits from digital participation. This study advances understanding of digital inclusion's differential impacts and mechanisms of action, supporting the development of cognitive-informed digital inclusion programs and suggesting the integration of cognitive training and digital skills development in mental health interventions for older adults.

New research shows that a high-salt diet may cause depression-like symptoms through immune changes in the brain.

A new study found that older adults with insomnia exposed to inflammation have triple the risk of developing depression, suggesting they may benefit from inflammation-targeted treatments. ...

The study links part-time work in older adults to higher depression rates, suggesting that less work doesn't always equate to better mental health outcomes.

A recent study highlights a connection between specific dietary habits and mental health. By analyzing genetic markers and thousands of medical records, researchers found that frequently adding salt to food elevates the odds of experiencing depression.

A large new study has found that older adults with high triglyceride-glucose levels—a marker tied to insulin resistance and metabolic health—do not appear to be at increased risk for developing depression....

A new study published in Development and Psychopathology sheds light on how depression may be transmitted from mothers to daughters through differences in how the brain responds to errors. The researchers...

A new study suggests that the way people attempt to lose weight might have a meaningful impact on their mental health. The research, published in the Journal of Affective Disorders, showed that healthy...

Here's how we can try to lower it.

The early bird catches the worm, while the night owl is more at risk of developing depression. That’s according to a new study that suggests people who prefer waking up and staying up late are more...
