The research suggests that even brief meditation practices can lead to improved mental well-being, making it accessible for time-crunched individuals.
Researchers found ketamine restores functional connectivity and ensemble activity of neurons and eliminates depression-related behaviors. Dendritic spine formation is crucial for maintaining remission, but its slow process may indicate that it's a consequence of ketamine-induced rescue of prefrontal cortex circuit activity.
Researchers found that ketamine restores dendritic spines in the prefrontal cortex of mice with depression-like behavior. Healthy dendritic spines are crucial for long-term antidepressant effects, suggesting interventions to enhance their survival may be helpful in sustaining ketamine's benefits.

The study's findings suggest that widespread cannabis use among young people makes the scale of the risk more serious, with a population attributable risk of around 7%.
The USPSTF recommends providing counseling interventions to pregnant and postpartum women at increased risk of depression, or referring patients to those services. Depression is a common complication during pregnancy and after childbirth, affecting both women and children.
Researchers found that walnut consumers had lower depression scores and experienced greater energy levels, concentration, and optimism compared to non-consumers. Walnut's unique fatty acid profile was also associated with the benefits.
Researchers found that self-compassion exercises calmed the heart rate and reduced stress responses in healthy individuals. This approach has been linked to improved mental health outcomes and may be beneficial for people with depression. Future studies aim to investigate this method further.

Experts debate the effectiveness of electroconvulsive therapy (ECT) in treating severe depression, with some arguing it has no long-term benefits compared to placebo and can cause brain damage. Others claim ECT is effective and safe for treatment-resistant depression, with most side effects resolving within weeks.
A new study finds that stress increases rapid-eye-movement (REM) sleep, associated with genes involved in cell death and survival. The research suggests that changes in REM sleep may contribute to mood disorders like depression by activating signaling pathways in the brain.
