One of the most frustrating challenges for some stroke patients can be the inability to find and speak words even if they know what they want to say. Speech therapy is laborious and can take months. New research is seeking to cut that time significantly, with the help of non-invasive brain stimulation. http://medicalxpress.com/news/2012-04-brain-speech-memory-numerical-abilities.html Neuroscience Mon, 02 Apr 2012 11:05:35 EST news252583523 (Medical Xpress) -- Brain stimulation can markedly improve people's ability to solve highly complex problems, a recent University of Sydney study suggests. http://medicalxpress.com/news/2012-03-impossible-problem-non-invasive-brain.html Neuroscience Thu, 29 Mar 2012 07:57:53 EST news252226661 Ever gone to the movies and forgotten where you parked the car?

The study was published Online First by Archives of General Psychiatry. http://medicalxpress.com/news/2012-01-deep-brain-results-unipolar-bipolar.html Psychology & Psychiatry Mon, 02 Jan 2012 16:00:17 EST news244731888 Major depressive disorder is a major public health problem that affects 7% of the population during any 12-month period and affects around 1 in 6 people throughout their lifetime. A Seminar published Online First by the Lancet reviews recent developments relating to this seriously disabling condition, and concludes that most patients need several sequential treatment steps for remission of their major depression. The Seminar also explains why deep brain stimulation is a treatment that holds promise for the future. It is written by Professors David J Kupfer, Ellen Frank, and Mary L Phillips, all of University of Pittsburgh Medical Center, PA, USA. http://medicalxpress.com/news/2011-12-patients-sequential-treatment-remission-major.html Psychology & Psychiatry Mon, 19 Dec 2011 18:30:01 EST news243520712 (Medical Xpress) -- Tiny electric currents applied across regions of the brain can improve hand movements in recovering stroke patients for a short period, an Oxford University study has demonstrated. http://medicalxpress.com/news/2011-12-tiny-electric-currents-aid-recovery.html Neuroscience Thu, 08 Dec 2011 07:30:03 EST news242550348 An estimated 300,000 people in North America are afflicted with dystonia, a disorder characterized by a progressive loss of motor control. Patients with generalized dystonia grapple with involuntary muscle spasms that lead to uncontrolled twisting and turning in awkward, sometimes painful postures. Although cognition, intelligence and life span are often normal, the disorder can have a devastating impact on quality of life, as its victims frequently struggle to perform simple activities of daily living. http://medicalxpress.com/news/2011-11-mystery-dystonia-advanced-imaging.html Neuroscience Mon, 14 Nov 2011 09:27:11 EST news240485223 (Medical Xpress) -- What drives addicts to repeatedly choose drugs, alcohol, cigarettes, overeating, gambling or kleptomania, despite the risks involved? http://medicalxpress.com/news/2011-10-scientists-brain-circuitry-linked-healthy.html Neuroscience Sun, 30 Oct 2011 14:00:31 EST news239200577 The American Academy of Neurology is releasing an updated guideline on how to best treat essential tremor, which is the most common type of tremor disorder and is often confused with other movement disorders such as Parkinson's disease. The guideline is published in the October 19, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology. http://medicalxpress.com/news/2011-10-aan-guideline-essential-tremor.html Neuroscience Wed, 19 Oct 2011 16:22:21 EST news238260125 Parkinson's disease (PD) is a devastating and incurable disease that causes abnormal poverty of movement, involuntary tremor, and lack of coordination. A technique called deep brain stimulation (DBS) is sometimes used to improve motor symptoms in patients with advanced disease. Now, a study published by Cell Press in the October 20 issue of the journal Neuron describes a new and more effective DBS paradigm that makes real-time adjustments in response to disease dynamics and progression and may be better for managing symptoms of advanced PD. http://medicalxpress.com/news/2011-10-next-generation-brain-treatment-parkinson-disease.html Parkinson's & Movement disorders Wed, 19 Oct 2011 12:42:38 EST news238246939 Take your time. Hold your horses. Sleep on it. When people must decide between arguably equal choices, they need time to deliberate. In the case of people undergoing deep brain stimulation (DBS) for Parkinson's disease, that process sometimes doesn't kick in, leading to impulsive behavior. New research into why that happens has led scientists to a detailed explanation of how the brain devotes time to reflect on tough choices. http://medicalxpress.com/news/2011-09-deep-brain-tough-choices.html Neuroscience Sun, 25 Sep 2011 13:18:25 EST news236175492 Stimulating a specific region of the brain leads to the production of new brain cells that enhance memory, according to an animal study in the September 21 issue of The Journal of Neuroscience. The findings show how deep brain stimulation (DBS) — a clinical intervention that delivers electrical pulses to targeted areas of the brain — may work to improve cognition. http://medicalxpress.com/news/2011-09-electrical-brain-boosts-birth-cells.html Neuroscience Tue, 20 Sep 2011 17:40:22 EST news235759190 Henry Ford Hospital became the third hospital in the United States to perform a Deep Brain Stimulation (DBS) procedure inside an Intraoperative Magnetic Resonance Imaging scanner, or iMRI. http://medicalxpress.com/news/2011-09-dbs-parkinson-disease-imri.html Parkinson's & Movement disorders Mon, 19 Sep 2011 11:24:15 EST news235650226 (PhysOrg.com) -- People have been lying to one another likely for as long as they have been able to communicate, and for likely just as long, people have been trying to figure out a way to get the truth out of someone suspected of lying. Now, new research by Inga Karton and Talis Bachmann, both of Estonia, have found that there might be a way to nudge people into being a little more honest when asked questions. Using powerful magnets, as they describe in their paper published in Behavioural Brain Research, applied to the forehead so as to impact the functioning of the dorsolateral prefrontal cortex, appears to impact the ease with which a person can lie. http://medicalxpress.com/news/2011-09-magnetic-brain-lying-difficult.html Psychology & Psychiatry Wed, 07 Sep 2011 10:20:36 EST news234609600 One of the biggest financing rounds for furthering the work of a doctoral student has just been completed at EPFL.
