Through a series of investigations in mice and humans, Johns Hopkins researchers have identified a protein that appears to be the target of both antidepressant drugs and electroconvulsive therapy. Results of their experiments explain how these therapies likely work to relieve depression by stimulating stem cells in the brain to grow and mature. In addition, the researchers say, these experiments raise the possibility of predicting individual people's response to depression therapy, and fine-tuning treatment accordingly. Reports on separate aspects of the research were published in December on the Molecular Psychiatry website, and will also appear in the Feb. 7 issue of Cell Stem Cell. http://medicalxpress.com/news/2013-02-uncovers-key-antidepressant-response.html Psychology & Psychiatry Thu, 07 Feb 2013 12:00:01 EST news279448470 (Medical Xpress) -- Online depression therapy programs can have a positive impact on more than just depressive symptoms, a new study from The Australian National University reveals. http://medicalxpress.com/news/2012-07-online-depression-big-impact.html Psychology & Psychiatry Mon, 02 Jul 2012 08:55:06 EST news260438085 Good news for the 13 per cent of the population with depressive personality traits: their negative outlook does not have to be permanent.
