Testosterone may trigger a brain chemical process linked to schizophrenia but the same sex hormone can also improve cognitive thinking skills in men with the disorder, two new studies show. http://medicalxpress.com/news/2013-04-scientists-testosterone-role-schizophrenia.html Neuroscience Fri, 26 Apr 2013 08:20:01 EST news286182507 Close family members of people with Alzheimer's disease are more than twice as likely as those without a family history to develop silent buildup of brain plaques associated with Alzheimer's disease, according to researchers at Duke Medicine. http://medicalxpress.com/news/2013-04-family-history-alzheimer-abnormal-brain.html Alzheimer's disease & dementia Wed, 17 Apr 2013 17:00:01 EST news285423778 The Journal of Neuroscience has published a study led by researchers at the Max Planck Florida Institute for Neuroscience, the first and only U.S. extension of the prestigious Max Planck Society, that may hold a stunning breakthrough in the fight to treat Alzheimer's disease. The study potentially identifies a cause of Alzheimer's disease—based on a newly-discovered signaling pathway in cellular models of Alzheimer's disease—and opens the door for new treatments by successfully blocking this pathway. The Institute, which recently opened in December 2012, focuses solely on basic neuroscience research that aims to analyze, map, and decode the human brain—the most important and least understood organ in the body. http://medicalxpress.com/news/2013-03-major-discovery-alzheimer-disease.html Alzheimer's disease & dementia Tue, 19 Mar 2013 17:30:41 EST news282933034 A team of clinicians from Sydney, Australia and Plymouth, UK, have taken the paper-based Addenbrooke's Cognitive Examination (ACE-III), one of the most popular and commonly-used screening tools for dementia and translated it into app form for more accurate assessment and wider use within the clinical team. http://medicalxpress.com/news/2013-03-app-dementia.html Alzheimer's disease & dementia Tue, 12 Mar 2013 11:00:14 EST news282304807 For the first time in Canada, patients attending a family practice clinic will be offered genetic testing to see whether or how they will respond to psychiatric medication treatment, in partnership with the Centre for Addiction and Mental Health (CAMH). http://medicalxpress.com/news/2013-01-family-genetic-effective-psychiatric-meds.html Psychology & Psychiatry Wed, 30 Jan 2013 14:44:08 EST news278779053 (Medical Xpress)—Australian diabetes experts, psychiatrists and neuroscientists have reported the benefits of measuring depression and disease-related distress in patients with diabetes. They have also shown that distress is influenced by heritable genetic changes in the way patients' bodies handle serotonin, a neurotransmitter that regulates mood. http://medicalxpress.com/news/2013-01-distress-people-diabetes.html Psychology & Psychiatry Tue, 22 Jan 2013 07:50:01 EST news278062334 Injecting botox into the arm muscles of stroke survivors, with severe spasticity, changes electrical activity in the brain and may assist with longer-term recovery, according to new research. http://medicalxpress.com/news/2013-01-dont-botox-heador.html Neuroscience Tue, 08 Jan 2013 09:06:03 EST news276858351 (Medical Xpress)—A bird listening to birdsong may experience some of the same emotions as a human listening to music, suggests a new study on white-throated sparrows, published in Frontiers of Evolutionary Neuroscience. http://medicalxpress.com/news/2012-12-birdsong-theory-music-uniquely-human.html Neuroscience Thu, 27 Dec 2012 06:24:18 EST news275811850 A simple word-training program has been found to restore key words in people with a type of dementia that attacks language and our memory for words. http://medicalxpress.com/news/2012-11-re-learning-words-lost-dementia.html Alzheimer's disease & dementia Tue, 27 Nov 2012 09:44:07 EST news273231837 (Medical Xpress)—New neuroscience research is confirming an old adage about the power of a handshake: strangers do form a better impression of those who proffer their hand in greeting.

For years this phenomenon remained a mystery. Reporting in the June 10 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that a light-capturing pigment molecule in photoreceptors can be triggered by heat, as well, giving rise to these false alarms. http://medicalxpress.com/news/2011-06-animals-dont-infrared-vision.html Neuroscience Thu, 09 Jun 2011 15:31:07 EST news226852249
