Using an MRI-based algorithm effectively differentiated cases 75 percent of the time, according to the study, published in the December 26th, 2012, issue of Neurology, the medical journal of the American Academy of Neurology. The non-invasive approach reported in this study can track disease progression over time more easily and cost-effectively than other tests, particularly in clinical trials testing new therapies. http://medicalxpress.com/news/2012-12-mri-screen-patients-alzheimer-disease.html Alzheimer's disease & dementia Wed, 26 Dec 2012 16:00:06 EST news275576983 (Medical Xpress)—On the surface, obsessive compulsive disorder (OCD) and attention deficit/hyperactivity disorder (ADHD) appear very similar, with impaired attention, memory, or behavioral control.

A definitive diagnosis offers relief to these individuals, as symptoms of TMAU can hinder social and workplace interactions and cause psychological distress. But once the disease is identified, these debilitating symptoms can be ameliorated using changes in diet and other approaches. http://medicalxpress.com/news/2011-08-undiagnosed-trimethylaminuria-cases-personal-malodor.html Diseases, Conditions, Syndromes Wed, 31 Aug 2011 11:37:04 EST news234009403 Sepsis is the name of an infection that causes a series of reactions in the body, which in the worst case can prove fatal. The problem for both patients and doctors is that the early symptoms are difficult to distinguish from less dangerous infections such as a severe flu or winter vomiting disease. A researcher at Lund University in Sweden has now discovered a substance in the blood which shows both whether a patient has sepsis and how serious the case is. http://medicalxpress.com/news/2011-05-quicker-treatment-severe-sepsis.html Medical research Mon, 23 May 2011 09:53:26 EST news225363194
