Experts at UCLA have noted actual changes in brain function among patients given placebos for the treatment of major depression, and they say the changes are different than those recorded in patients taking anti-depressant medication. Most changes occurred in the area of the brain thought to control memory, behavior, and attention. The lead study author says it's been known for years that many psychiatric patients will respond favorably to a placebo, but until now, there's never been evidence of actual changes in the brain.
Endometriosis is a painful condition which causes scarring in the lining of the uterus. It's one of the leading causes of infertility in women. Now, a study of the family trees of 750 women with Endometriosis shows the genetic link to that may be a strong one. In Europe's leading reproductive medicine journal, Human Reproduction, Iceland researchers compiled information from a computer database that includes the entire population of Iceland with records dating back to the ninth century. They discovered that a woman has more than five times the risk of developing Endometriosis if her sister has the disease. Even having a cousin with Endometriosis raises a woman's risk by over 50%.
