A new research led by Professor Hannes Lohi at the University of Helsinki, Finland, revealed several similarities between compulsive behavior in dogs and humans: Early onset, recurrent compulsive behaviors, increased risk for developing different types of compulsions, compulsive freezing, the beneficial effect of nutritional supplements, the effects of early life experiences and sex hormones and genetic risk. http://phys.org/news264686479.html Biology Mon, 20 Aug 2012 13:01:49 EST news264686479 Research from the University of California, San Diego School of Medicine provides new clues for the compulsive behavior and cognitive defects associated with a rare childhood neurological disease called Lesch-Nyhan Disease (LND). Two pathways found to be defective in LND are known to be associated with other neurodegenerative disease, such as Alzheimer's and Parknson's diseases, suggesting common causes of cognitive and behavioral defects in these neurological disorders. http://phys.org/news215457089.html Medicine & Health Fri, 28 Jan 2011 17:11:54 EST news215457089 Researchers have shed new light on dopamine's role in the brain's reward system, which could provide insight into impulse control problems associated with addiction and a number of psychiatric disorders. http://phys.org/news211037006.html Medicine & Health Wed, 08 Dec 2010 13:23:41 EST news211037006 Ever get a buzz from eating chocolate?

The study, published by Cell Press in the January 14th issue of the journal Neuron, provides fascinating new insight into the brain mechanisms that underlie a predisposition to behavioral addictions, such as pathological gambling and shopping. http://phys.org/news182609510.html Medicine & Health Wed, 13 Jan 2010 14:30:02 EST news182609510 A canine chromosome 7 locus that confers a high risk of compulsive disorder susceptibility has been identified through a collaboration between the Behavior Service at the Cummings School of Veterinary Medicine, the Program in Medical Genetics at the University of Massachusetts Medical School and the Broad Institute at the Massachusetts Institute of Technology. The findings are published in the January 2010 edition of Molecular Psychiatry. http://phys.org/news182000118.html Medicine & Health Wed, 06 Jan 2010 11:36:08 EST news182000118
