A new study found that people with a certain genetic variant, short alleles of the gene 5-HTTLPR, displayed greater genuine smiling and laughing while watching cartoons or subtly amusing film clips. The research suggests that this genetic variant may be associated with positive emotional expressions.

Researchers discovered a metabolic signature associated with major depression, including changes in mitochondrial DNA and telomere length. The findings suggest that depression may be linked to the body's response to environmental stressors.
The study found a significant increase in major depression among US adults during the Great Recession, with prevalence rising from 2.33% to 3.79%. Less severe depression also saw a decline in prevalence after 2009-2010. Vulnerable populations such as those living in poverty or with less than a high school education were most affected.
Researchers found that mindfulness-based cognitive therapy (MBCT) is not more effective than maintenance antidepressant medication in preventing depression relapse. However, MBCT may offer similar protection against depressive relapse for people with a history of multiple episodes, with no significant cost difference.
A leading psychiatrist argues that depression is not caused by low serotonin levels and that effective treatments do not raise these levels. The serotonin reuptake inhibiting drug class, popularized in the late 1980s, was marketed despite lacking evidence of its effectiveness.

Research from San Francisco State University reveals that fertility treatment patients are more likely to experience major depressive disorder (MDD) than the general population. A key factor in predicting a patient's risk is whether they have a previous diagnosis of MDD, which is often overlooked by healthcare providers.
A new study suggests that symptoms of depression and insomnia are the strongest predictors of having frequent nightmares. Researchers found a strong connection between well-being and nightmares, particularly in individuals with severe depressive symptoms.
A study of 14,348 Swiss individuals found that those with depressive symptoms have a higher risk of developing physical diseases, especially arthrosis and arthritis. The researchers suggest that lack of interest in physical activity or inflammatory processes may be key factors in this association.
