Patients over the age of 60 who have elective surgeries such as joint replacements, hysterectomies and other non-emergency, inpatient procedures, are at an increased risk for long-term cognitive problems, according to a new study led by Duke University Medical Center researchers.The study also found that elderly patients who developed these postoperative cognitive problems were more likely to die in the first year after surgery. “We have known that patients undergoing heart surgery are at risk for cognitive dysfunction — problems with memory, concentration, processing of information — but the effects of non-cardiac surgeries on brain function are not as well-understood,” said Terri Monk, M.D., an anesthesiologist at Duke and the Durham Veterans Affairs Medical Center, and lead investigator on the study. “Our study found that increasing age put patients in this population at greater risk for cognitive problems and this … Read more

Novel treatment strategies for major depression with broader treatment success or a more rapid onset of action would have immense impact on public health, a new study published in the December 1st issue of Biological Psychiatry explains. This new study reports findings that support the evaluation of a potential new antidepressant agent.According to the lead author on this study, Kamilla Miskowiak, MSc: “Although depression is often related to problems in the chemistry of the brain, recent evidence also suggests that there may be structural problems as well with nerve cells not being regenerated as fast as normal or suffering from toxic effects of stress and stress hormones.” This led the researchers to evaluate the effects of erythropoietin (Epo), a hormone naturally produced by the kidneys that stimulates the formation of red blood cells and is known as a treatment for … Read more

I regularly take omega 3 acids daily with fish oil supplements. Here is an interesting article I found from http://www.sciencedaily.com/releases/2007/12/071220082829.htm Researchers at Cedars-Sinai Medical Center’s Department of Psychiatry and Behavioral Neurosciences are seeking participants for a clinical trial examining whether two polyunsaturated Omega-3 fatty acids are effective treatments for depression. The two fatty acids being studied — docosahexanoic acid (DHA) and eicosapentanoic acid (EPA) — are found naturally in fish oil, flaxseed and walnuts. Previous studies have indicated that nutritional supplements that contain Omega-3 fatty acids can be an effective treatment for depression, but this is the first to systematically test the two specific fatty acids against each other and against placebo in a large sample of people with major depression. DHA and EPA have anti-inflammatory properties and help stabilize brain cell membranes, both of which play a role in … Read more

Can’t smell the roses? Maybe you’re depressed. Smell too much like a rose yourself? Maybe you’ve got the same problem. Scientists from Tel Aviv University recently linked depression to a biological mechanism that affects the olfactory glands. It might explain why some women, without realizing it, wear too much perfume.Scientific research that supports this theory was published this year in the journal Arthritis and Rheumatism. “Our scientific findings suggest that women who are depressed are also losing their sense of smell, and may overcompensate by using more perfume,” explains researcher Prof. Yehuda Shoenfeld, a member of the Sackler Faculty of Medicine at Tel Aviv University. “We also believe that depression has biological roots and may be an immune system response to certain physiological cues.” Women who are depressed are also more likely to lose weight. With a reduced sense of … Read more
