Parkinson's disease is a neurodegenerative disorder characterized by the death of dopamine-producing neurons in the midbrain, resulting in motor symptoms such as tremors and stiffness. The cause of cell death remains unknown and researchers have long sought a way to replace the lost dopamine-producing cells. A study led by Takuya Hayashi from the RIKEN Center for Molecular Imaging Science now suggests that in monkeys such neurons can be derived from bone marrow stem cells and then transplanted back into the brain to reverse the symptoms of this devastating disease. http://medicalxpress.com/news/2013-04-dopamine-producing-neurons-derived-bone-marrow.html Parkinson's & Movement disorders Mon, 22 Apr 2013 09:20:02 EST news285839534 Imagine a hospital where patient data from numerous sources is made accessible to ward physicians with the help of hyperlinks and intelligent indexing. Imagine a healthcare system that hands its patients – not an envelope or a CD-ROM – but an integrated dataset that allows them to truly understand their illness, and even use the Internet to obtain additional information. Imagine a radiologist who uses semantic technologies to navigate smoothly through the myriad imaging data. Welcome to the future of semantic technologies in health information retrieval. http://medicalxpress.com/news/2013-04-knowledge-pure.html Other Mon, 15 Apr 2013 09:10:01 EST news285233448 Addiction may result from abnormal brain circuitry in the frontal cortex, the part of the brain that controls decision-making. Researchers from the RIKEN Center for Molecular Imaging Science in Japan collaborating with colleagues from the Montreal Neurological Institute of McGill University in Canada report today that the lateral and orbital regions of the frontal cortex interact during the response to a drug-related cue and that aberrant interaction between the two frontal regions may underlie addiction. Their results are published today in the journal Proceedings of the National Academy of Sciences. http://medicalxpress.com/news/2013-01-fmri-uncovers-neural-mechanism-underlying.html Neuroscience Mon, 28 Jan 2013 15:00:12 EST news278590198 Parkinson's disease is a degenerative disorder of the central nervous system that is characterized by tremors, rigidity, slowness of movement, and difficulty walking. It is caused by loss of the neurons that produce the neurotransmitter dopamine (known as dopaminergic neurons). One of the primary goals in Parkinson's disease research is to develop a replacement for dopaminergic neurons. http://medicalxpress.com/news/2012-12-stem-cell-derived-dopaminergic-neurons-motor.html Parkinson's & Movement disorders Mon, 03 Dec 2012 12:00:13 EST news273754334 (HealthDay) -- The ability to make decisions in new situations declines with age, apparently because of changes in the brain's white matter, a new imaging study says. http://medicalxpress.com/news/2012-04-brain-hamper-decision-making-age.html Neuroscience Tue, 17 Apr 2012 15:40:01 EST news253892437
