Research on depression and its treatment. Covers stress-response biology, ketamine and dopamine-targeting therapies, treatment-resistant cases, and brain mechanisms.
Researchers found that children's negative beliefs about mothers and peers predict rejection and depression in a multidimensional study of 81 preadolescent children. Non-depressed kids tend to have more positive attributes about their mothers, while depressed kids may experience more stress in their family.
Researchers found that sadness, depression, and hopelessness can exacerbate asthma symptoms in children. The vagus nerve plays a key role in this process, suggesting new avenues for treatment. The study's findings highlight the importance of addressing depression in asthmatic children to improve their overall health.
A study by Penn researchers found that minor depression in elderly populations is linked to differences in brain structure, specifically smaller prefrontal lobe volume. This finding has important neurobiologic implications for minor depression and may inform the development of new treatments.
Researchers found significant brain tissue loss in individuals with bipolar and unipolar depression, which may help understand the causes of mood disorders. The study's findings provide new information for developing more effective treatments.
A Duke University study found that short, vigorous workouts can temporarily reduce symptoms of depression by up to 82% in participants over 50. The results also showed an increase in feelings of vigor after the test.
A study by the National Institute of Mental Health found that depression increases a woman's risk for broken bones, particularly hip fractures. Women with major depression had significantly lower bone mineral density compared to their age-matched controls.
