Now, studying spinal fluid samples and health data from 201 research participants at the Charles F. and Joanne Knight Alzheimer's Disease Research Center, the researchers have shown the markers are accurate predictors of Alzheimer's years before symptoms develop. http://medicalxpress.com/news/2013-05-alzheimer-markers-mental-decline.html Alzheimer's disease & dementia Tue, 14 May 2013 06:48:36 EST news287732906 (Medical Xpress)—Scientists' picture of how a gene strongly linked to Alzheimer's disease harms the brain may have to be revised, researchers at Washington University School of Medicine in St. Louis have found. http://medicalxpress.com/news/2013-05-perspective-role-major-alzheimer-gene.html Medical research Tue, 07 May 2013 07:32:39 EST news287130751 Young adults with an autism spectrum disorder (ASD) are more likely to never see friends, never get called by friends, never be invited to activities and be socially isolated. http://medicalxpress.com/news/2013-05-social-isolation-young-adults-autism.html Autism spectrum disorders Thu, 02 May 2013 06:34:55 EST news286695287 (Medical Xpress)—Either physical therapy or arthroscopic surgery can relieve pain and improve mobility in patients with a torn meniscus and arthritis in the knee, according to researchers from Washington University School of Medicine in St. Louis and six other centers. http://medicalxpress.com/news/2013-04-physical-therapy-good-surgery-knee.html Diseases, Conditions, Syndromes Fri, 12 Apr 2013 06:37:25 EST news284967439 (Medical Xpress)—A gene with a colorful name – mindbomb 1 – plays a key role far beyond the brain. New research at Washington University School of Medicine in St. Louis shows that mindbomb 1 may be involved in repairing cells injured by infection or inflammation in the stomach and pancreas. Researchers also found hints that mindbomb 1 problems may have connections to cancer in those organs. http://medicalxpress.com/news/2013-04-brain-building-gene-key-role-gut.html Genetics Fri, 05 Apr 2013 06:42:01 EST news284362912 (Medical Xpress)—Washington University School of Medicine in St. Louis is playing a leading role in one of the National Institutes of Health's (NIH) first clinical trials to improve treatments for rare and neglected diseases. http://medicalxpress.com/news/2013-04-drug-niemann-pick-crare-deadly-childhood.html Diseases, Conditions, Syndromes Wed, 03 Apr 2013 08:29:54 EST news284196165 The American Academy of Neurology issued new guidelines last week for assessing school-aged athletes with head injuries on the field.

The finding is an important step toward developing a vaginal gel that may prevent the spread of HIV, the virus that causes AIDS. http://medicalxpress.com/news/2013-03-nanoparticles-bee-venom-hiv.html HIV & AIDS Fri, 08 Mar 2013 08:20:29 EST news281953153 (Medical Xpress)—Anyone whose hand or foot has "fallen asleep" has an idea of the numbness and tingling often experienced by people with peripheral nerve damage. The condition also can cause a range of other symptoms, including unrelenting pain, stinging, burning, itching and sensitivity to touch. http://medicalxpress.com/news/2013-03-clues-peripheral-nerve.html Neuroscience Thu, 07 Mar 2013 07:07:50 EST news281862461 (Medical Xpress)—Viruses often spread through the brain in patchwork patterns, infecting some cells but missing others. New research at Washington University School of Medicine in St. Louis helps explain why. The scientists showed that natural immune defenses that resist viral infection are turned on in some brain cells but switched off in others. http://medicalxpress.com/news/2013-03-brain-cells-virus-fighters.html Medical research Thu, 07 Mar 2013 07:07:12 EST news281862424 (Medical Xpress)—In the weeks, months and years after a severe head injury, patients often experience epileptic seizures that are difficult to control.
