A study from Harvard Medical School investigators at Massachusetts General Hospital has identified for the first time changes in the metabolic activity of a key brain region in patients successfully treated for depression with psychodynamic psychotherapy, suggesting a mechanism of action behind one of the most historically important and widely practiced forms of therapy. 

They also found evidence that pretreatment metabolism in a different brain structure might predict which patients are likely to respond to that form of therapy. 

More than 100,000 people have electrical stimulation devices implanted in their brains to treat Parkinson’s disease. The implants block the abnormal nerve signals that cause Parkinson’s symptoms like tremor and stiffness.

Now the Department of Defense is putting up $70 million to develop a new generation of brain implants to target depression and PTSD. These devices would detect and correct abnormal brain activity in real time.

Blue light can both set the mood and set in motion important biological responses. Researchers at the University of Pennsylvania’s School of Medicine and School of Arts and Sciences have teased apart the separate biological responses of the human eye to blue light, revealing an unexpected contest for control. Their work addresses the properties of melanopsin, a light-sensitive protein in the eye that establishes the rhythm of our day-night cycle and the familiar constriction of the pupil to bright light.

What's The Connection Between Depression And Heart Disease?

"It's not uncommon for people who undergo bypass surgery for heart disease to also deal with depression. And the reverse is also true as well. People with depression are at higher risk for heart problems. That linkage is the focus of a new study by Dr. Bruce Rollman, a professor of medicine at the Pittsburgh School of Medicine."

Say a pediatrician notices that one of her teenage patients is showing signs of depression. In most cases, the doctor will notify parents and prescribe an antidepressant or recommend a therapist.

The trouble is, many of those teens won't go to therapy or won't stick with it. And that's part of a bigger problem: Nearly two-thirds of adolescents who have had a major depressive episode don't get treatment, according to the Substance Abuse and Mental Health Services Administration.

According to a 2013 meta-analysis, those with diabetes are 25 percent more likely to become depressed, a well-accepted association. 

Lead is well known for causing permanent behavioral and cognitive problems in children, but a study says it may also cause less obvious problems like depression, too, even at low levels.

That's the word from a study tracking the health of 1,341 children in Jintan, China, where the health effects of pollution from rapid development have become a national concern.

According to a new study conducted by Simon Bacon, Ph.D., people with depression may take longer to recover after strenuous exercise. The study looked at the stress test results of 900 patients who may have heart disease or who have a family history of heart disease. Before entering the study, participants were given a psychiatric evaluation. The study found that those with depression took longer to relax after strenuous exercise. Dr. Bacon is an assistant professor of exercise science at Concordia University, Montreal.
