Recently a new study used a model for seasonal affective disorder to find out why and how some people don’t develop depression despite being genetically predisposed to it. The findings also shed light on potential new treatments for seasonal depression.
According National Institute of Mental Health estimate that over 16 million people in the United States, or 6.7 percent of the population, will have had more than one episode of major depression during the past year. From the research 5 percent live, has been suffering with seasonal affective disorder (SAD), or seasonal depression.The symptoms of SAD are so similar to those of depression that it can sometimes be hard to distinguish between the two. SAD, also known as winter blues, typically affects women. The shocking fact is that, 4 out of 5 people most suffering can been seen in women, and the reasons for this predisposition are likely to be genetic. However, while some people are genetically prone to the condition, they resist the environmental factors that might trigger it.So, new research set out to examine the neurobiology of SAD in an attempt to understand what it actually is that makes some people more resilient to developing depression.The new study was led by Dr. Brenda McMahon, of Rigshospitalet in Copenhagen, Denmark, and the findings were published in the journal European Neuropsychopharmacology.[...]
