Doctors often diagnose tuberous sclerosis complex (TSC) based on the abnormal growths the genetic disease causes in organs around the body. Those overt anatomical structures, however, belie the microscopic and mysterious neurological differences behind the disease's troublesome behavioral symptoms: autism, intellectual disabilities, and seizures. In a new study in mice, Brown University researchers highlight a role for a brain region called the thalamus and show that the timing of gene mutation during thalamus development makes a huge difference in the severity of the disease. http://medicalxpress.com/news/2013-05-advance-tuberous-sclerosis-brain-science.html Neuroscience Thu, 09 May 2013 12:00:20 EST news287306747 (Medical Xpress)—A drug that is currently used for cancer can relieve and slow down the progression of the autoimmune disease multiple sclerosis (MS) in rats, according to a new study published in PLOS ONE. The discovery, which was made by researchers at Karolinska Institutet, might one day lead to better forms of treatment for patients with MS. http://medicalxpress.com/news/2013-02-cancer-drug-treatment-multiple-sclerosis.html Medical research Thu, 21 Feb 2013 10:02:01 EST news280663311 (HealthDay)—People who eat large, tropical predatory reef fish such as barracuda and grouper may be at risk for a form of food poisoning called ciguatera fish poisoning, U.S. health officials reported Thursday. http://medicalxpress.com/news/2013-01-fish-grouper-barracuda-pose-food-poisoning.html Health Thu, 31 Jan 2013 15:50:02 EST news278867179 Treatment with a novel agent that inhibits the activity of SIRT2, an enzyme that regulates many important cellular functions, reduced neurological damage, slowed the loss of motor function and extended survival in two animal models of Huntington's disease. The study led by Massachusetts General Hospital (MGH) researchers will appear in the Dec. 27 issue of Cell Reports and is receiving advance online release. http://medicalxpress.com/news/2012-11-enzyme-inhibition-huntington-disease-animal.html Neuroscience Thu, 29 Nov 2012 12:07:05 EST news273413207 (AP) — A deadly form of a common childhood illness has been linked to the mysterious child deaths in Cambodia that sparked alarm after a cause could not immediately be determined, health officials said Monday. http://medicalxpress.com/news/2012-07-cambodia-deaths-tied-common-child.html Diseases, Conditions, Syndromes Mon, 09 Jul 2012 04:16:27 EST news261026179 Studies suggest that neurotrophic factors, which play a role in the development and survival of neurons, have significant therapeutic and restorative potential for neurologic diseases such as Huntington's disease. However, clinical applications are limited because these proteins cannot easily cross the blood brain barrier, have a short half-life, and cause serious side effects. Now, a group of scientists has successfully treated neurological symptoms in laboratory rats by implanting a device to deliver a genetically engineered neurotrophic factor directly to the brain. They report on their results in the latest issue of Restorative Neurology and Neuroscience. http://medicalxpress.com/news/2012-06-device-implanted-brain-therapeutic-potential.html Neuroscience Mon, 18 Jun 2012 12:33:21 EST news259241577 Even mild head injuries can cause significant abnormalities in brain function that last for several days, which may explain the neurological symptoms experienced by some individuals who have experienced a head injury associated with sports, accidents or combat, according to a study by Virginia Commonwealth University School of Medicine researchers. http://medicalxpress.com/news/2012-05-mild-traumatic-brain-injury-neuronal.html Neuroscience Fri, 11 May 2012 07:50:01 EST news255940344 Blood flow abnormalities found in the brains of veterans with Gulf War illness have persisted 20 years after the war, and in some cases have gotten worse, according to a new study published online in the journal Radiology. http://medicalxpress.com/news/2011-09-chronic-abnormal-brain-blood-gulf.html Medical research Tue, 13 Sep 2011 03:04:41 EST news235101868 Since 1999, several outbreaks of West Nile Virus, which causes fever or severe neurological symptoms and is transmitted from birds to humans by blood-sucking mosquitoes, have been seen in the U.S., usually during the summer months.
