Three studies released today present possible positive news for people with Parkinson's disease. The studies, which will be presented at the American Academy of Neurology's 65th Annual Meeting in San Diego, March 16 to 23, 2013, report on treatments for blood pressure problems, the wearing-off that can occur when people have taken the main drug for Parkinson's for a long time, and for people early in the disease whose symptoms are not well-controlled by their main drugs. http://medicalxpress.com/news/2013-03-drugs-quality-life-people-parkinson.html Parkinson's & Movement disorders Thu, 14 Mar 2013 16:20:13 EST news282496805 (Medical Xpress)—What is the best intervention window for someone struggling with cocaine addiction? When he or she is in the middle of a drug binge, or after a period of abstinence when there is temptation to fall back into old habits? http://medicalxpress.com/news/2013-01-treatment-cocaine-addiction-relapse.html Psychology & Psychiatry Tue, 15 Jan 2013 07:18:42 EST news277456708 (Medical Xpress) -- University of Kansas researchers have found larger resting pupil size and lower levels of a salivary enzyme associated with the neurotransmitter norepinephrine in children with autism spectrum disorder. http://medicalxpress.com/news/2012-07-saliva-pupil-size-differences-autism.html Autism spectrum disorders Fri, 13 Jul 2012 07:44:56 EST news261384215 New research from the University at Buffalo suggests that cardiologists may have a new way to identify patients who are at the highest risk of sudden cardiac arrest, and the most likely to benefit from receiving an implantable cardiac defibrillator (ICD). http://medicalxpress.com/news/2012-05-imaging-patients-benefit-implantable-cardiac.html Cardiology Thu, 10 May 2012 11:13:43 EST news255867212 (Medical Xpress) -- Because addictions cause so much havoc in the lives of millions of people, researchers the world over are constantly looking for both their causes and ways to treat them. One such addiction, to gambling, has proven to be particularly tricky. To date, not a single approved medication has been found to help people who suffer from this category of addiction. Now however, thanks to the work of a team of scientists from the Kyoto University graduate school of medicine, researchers might be getting closer. They have found, as they explain in their paper in Molecular Psychiatry, that people with lower levels of the norepinephrine transporter in their brain, tend to take losing money less hard than do other people, which could of course, lead to gambling problems. http://medicalxpress.com/news/2012-02-japanese-norepinephrine-linked-gambling-addiction.html Psychology & Psychiatry Wed, 22 Feb 2012 10:30:01 EST news249126072 Stressed people fall into habits and their behaviour is not goal-directed. That the neurotransmitter norepinephrine plays a decisive role here is now reported in the Journal of Neuroscience by scientists from Bochum led by Dr. Lars Schwabe (RUB Faculty of Psychology). If the effect of norepinephrine is stopped by beta blockers, the stress effect does not occur. "The results may be important for addictive behaviours, where stress is a key risk factor" said Schwabe. "They are characterised by ingrained routines and habits." http://medicalxpress.com/news/2011-11-eyes-goal-stress.html Neuroscience Mon, 28 Nov 2011 09:24:00 EST news241694615 It's a common belief that there's a link between chronic stress and an increased risk of cancer. In new research published online by the International Journal of Cancer, scientists at The University of Western Ontario have taken a step toward confirming that belief. http://medicalxpress.com/news/2011-09-stress-breast-cancer.html Cancer Tue, 20 Sep 2011 12:04:00 EST news235738987
