When trying to determine the root cause of a person's dementia, using an MRI can effectively and non-invasively screen patients for Alzheimer's disease or Frontotemporal Lobar Degeneration (FTLD), according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania. 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 Thousands of Americans who may have been injected with a tainted steroid will have to wait weeks to see if they have been infected with meningitis as investigators seek answers to a widening outbreak. http://medicalxpress.com/news/2012-10-tainted-drug-outbreak.html Diseases, Conditions, Syndromes Sat, 13 Oct 2012 05:30:02 EST news269323703 Investigators from the University of Amsterdam, Netherlands, have shown that in most elderly patients invasive and expensive techniques, i.e. lumbar puncture and PET scan, are not useful to establish the diagnosis of Alzheimer's disease. They arrived at this conclusion after analysis of data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), a large collaborative research project of medical centers in the USA and Canada. http://medicalxpress.com/news/2012-03-mri-neuropsychological-alzheimer-disease-patients.html Alzheimer's disease & dementia Fri, 30 Mar 2012 09:48:01 EST news252319661 A new biomarker may help identify which people with mild memory deficits will go on to develop Alzheimer's disease, according to a new study published in the June 22, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology.
