This can lead to life-threatening weight loss. Using MRI technology, scientists at Heidelberg University Hospital have discovered for the first time processes in brain metabolism that explain this disturbed eating behavior. http://www.physorg.com/news168525822.html Medicine & Health Mon, 03 Aug 2009 14:10:01 EST news168525822 New imaging technology provides insight into abnormalities in the brain circuitry of patients with anorexia nervosa (commonly known as anorexia) that may contribute to the puzzling symptoms found in people with the eating disorder. In a review paper published on line in Nature Reviews Neuroscience, Walter Kaye, MD, professor of psychiatry and director of the Eating Disorders Program at the University of California, San Diego, and colleagues describe dysfunction in certain neural circuits of the brain which may help explain why people develop anorexia in the first place, and behaviors such as the relentless pursuit of dieting and weight loss. http://www.physorg.com/news167407077.html Medicine & Health Tue, 21 Jul 2009 14:58:24 EST news167407077 Bones are the body's first lines of defense.

But this is just the approach used in one treatment for anorexia nervosa. Known as Behavioral Family Therapy, or the Maudsley Approach, parents are called up on to supervise the eating habits of their anorexic child, feeding them high-calorie meals like milkshakes and macaroni and cheese until they regain a healthy weight. http://www.physorg.com/news157901274.html Medicine & Health Thu, 02 Apr 2009 14:29:53 EST news157901274 The study was initiated in 1985. A total of 51 teenagers with anorexia nervosa were studied, together with an equally large control group of healthy persons. The groups have been investigated and compared several times as the years have passed. http://www.physorg.com/news157288700.html Medicine & Health Thu, 26 Mar 2009 12:18:39 EST news157288700 (PhysOrg.com) -- Psychologist Elke Geraerts of the University of St Andrews has carried out a study of the difference between memories recalled by patients through suggestive therapies, compared with more natural recollections. http://www.physorg.com/news154193549.html Medicine & Health Wed, 18 Feb 2009 15:33:08 EST news154193549 Children and teenagers with even mild cases of anorexia exhibit abnormal bone structure, according to a new study appearing in the December issue of Radiology and presented at the annual meeting of the Radiological Society of North America (RSNA). http://www.physorg.com/news146220357.html Medicine & Health Tue, 18 Nov 2008 08:45:57 EST news146220357
