Smoking may impair mental function Men and women with a history of alcohol abuse may not see long-term negative effects on their memory and thinking, but female smokers do, a newly released study suggests.
In a study of 287 men and women ages 31 to 60, scientists observed that those with past alcohol-use disorders performed similarly on standard tests of cognitive function as those with no past drinking problems.
The findings were not as positive when it came to........Go to the Neurology news blog (Added on 3/15/2010 7:49:02 PM)
New Alzheimer's test offers better opportunitiesEarly detection is key to more effective therapy for Alzheimer's disease and other forms of cognitive impairment, and new research shows that a test developed at the University of Tennessee is more than 95 percent effective in detecting cognitive abnormalities linked to these diseases.

Weight-Bearing Exercise Does Not Prevent Increased Bone TurnoverWhile there are a number of benefits of losing weight, weight reduction also might negatively affect bones in the body. During weight loss, bones are being remodeled - breaking down old bone and forming new bone - at an accelerated rate. As a result, bone density is reduced, causing increased fragility. In a newly released study, University of Missouri scientists observed that weight-bearing exercise, in this case, fast walking or jogging, did........Go to the Weight watcher's blog (Added on 3/12/2010 8:01:19 AM)

Elective removal of ovaries during hysterectomyRemoval of the ovaries (bilateral oophorectomy) while performing a hysterectomy is common practice to prevent the subsequent development of ovary cancer. This prophylactic procedure is performed in 55% of all U.S. women having a hysterectomy, or approximately 300,000 times each year. An article in the March/recent issue of The Journal of Minimally Invasive Gynecology suggests that this procedure may do more harm than good.
