The study also highlights the importance of substance abuse treatment in reducing suicidal behavior among depressed veterans.
A study by NYU researchers reveals that brain regions associated with depression also play a role in generating human optimism. Optimism is linked to enhanced activation in the rostral anterior cingulate and amygdala, areas that show irregularities in depression.
A new study found that a synthetic form of THC increases serotonin levels in the brain at low doses, acting as an effective anti-depressant. However, at higher doses, the effect reverses and can worsen depression and psychosis.
The study found that mice with a better ability to cope with stress had increased activity of potassium channels in the brain, which counters increased nerve firing and BDNF release. In humans, depressed individuals showed a 40% increase in BDNF levels in the nucleus accumbens, suggesting a link between stress handling and depression.
Depression is associated with an increased risk of mortality and adverse cardiovascular outcomes, including heart attacks and strokes. Antidepressant treatments have been shown to be safe and effective in reducing mortality and improving health behaviors in patients with coronary artery disease.

These changes remain detectable even after thyroid hormone replacement therapy, suggesting a complex relationship between physical health and mental well-being.
A recent study found that antidepressant sertraline does not improve symptoms or survival in advanced cancer patients without major depression. The researchers concluded that the overmedicalisation of these patients should be avoided, and treatment with sertraline should be reserved for cases with a proven indication.
A new survey by researchers at the University of North Carolina at Chapel Hill found that the majority of doctors in North Carolina do not probe for signs of postpartum depression in new mothers. The study, to be published June 6, 2007, highlights the need for physicians to screen patients for depression during postpartum visits.
Most teens do not experience depression after first-time sex, but young girls and early-sex boys/girls in uncommitted relationships are at risk. The study suggests focusing on vulnerable teens rather than promoting a one-size-fits-all approach to sex education.
A Finnish study found that persistent smokers are at a higher risk of developing depressive symptoms compared to never smokers. In contrast, those who successfully quit smoking tend to experience elevated depressive symptoms in the short term, but this risk declines over time.
A survey estimated that approximately 4.4% of U.S. adults may have some form of bipolar disorder during their lifetime, with 2.4% having a sub-threshold condition. The study found that many individuals with bipolar symptoms receive treatment for depression rather than manic symptoms.
