12/6/13 - In a seemingly simple experiment, a scientist exposes rats to a certain pesticide over several days, and the rodents start showing symptoms remarkably similar to those seen in Parkinson's patients. But the scientific search for the causes of the disease, which affects 7 million to 10 million people worldwide, is nowhere near simple.
12/6/13 - A new study shows that a neurologist in an office thousands of miles away can deliver effective specialized care to people with Parkinson's disease. For individuals with the condition - many of whom have never seen a specialist - these "virtual house calls" could allow them to live independently while effectively manage the symptoms of the disease.
12/6/13 - Subthalamic nucleus deep brain stimulation can significantly improve the motor features of Parkinson's disease in carefully selected patients. However, effects of subthalamic nucleus deep brain stimulation on the social adjustment, coping strategies and mental health-related quality of life of these patients remain unclear.
12/5/13 - Scientists at The Scripps Research Institute (TSRI) have discovered a natural mechanism that cells use to protect mitochondria, the tiny but essential "power plants" that provide chemical energy for cells throughout the body. Damage to mitochondria is thought to be a significant factor in common neurodegenerative disorders, cancer and even the aging process.
12/5/13 - A successful joint collaboration between researchers at the Hebrew university of Jerusalem and the startup company TyrNovo may lead to a potential treatment of brain diseases. The researchers found that TyrNovo's novel and unique compound, named NT219, selectively inhibits the process of aging in order to protect the brain from neurodegenerative diseases, without affecting lifespan.
12/2/13 - Study uses patient-derived stem cells to show that a mutation in the alpha-synuclein gene causes increased vulnerability to pesticides, leading to Parkinson's disease.A team of researchers has brought new clarity to the picture of how gene-environmental interactions can kill nerve cells that make dopamine.
12/2/13 - Parkinson's disease is a common neurodegenerative disease in the elderly, which is pathologically characterized by selective loss of dopaminergic neurons. Compound preparations of Chinese medicines that can tonify the kidney have been reported to significantly improve symptoms of Parkinson's disease. However, the mechanism of action remains unclear.
11/28/13 - A new report has revealed that people with Parkinson's are dying while endlessly waiting for their local NHS to decide whether they're eligible for NHS continuing care funding - a funding package to provide free health care for people with severe health needs.
11/27/13 - Stanford University School of Medicine neuroscientists have discovered a new role played by a common but mysterious class of brain cells.
11/26/13 - Scientists at the National Institutes of Health have used RNA interference (RNAi) technology to reveal dozens of genes which may represent new therapeutic targets for treating Parkinson's disease. The findings also may be relevant to several diseases caused by damage to mitochondria, the biological power plants found in cells throughout the body.
11/26/13 - The physical decline experienced by Parkinson's disease patients eventually leads to disability and a lower quality of life. Depending on the individual, the disorder can progress rapidly or slowly.Scientists at UCLA and colleagues have now, for the first time, identified a biochemical signal in the blood associated with the faster-progressing form of Parkinson's.
11/25/13 - A vision is to implant nerve precursor cells in the diseased brains of patients with Parkinson's and Huntington's diseases, whereby these cells are to assume the function of the cells that have died off. However, the implanted nerve cells frequently do not migrate as hoped, rather they hardly move from the site.
11/16/13 - New research has suggested that a compound often exuded by fungus could be linked to symptoms of Parkinson's disease. The investigators say Parkinson's has previously been linked to exposure of human-made toxins, but their findings show that biological compounds also have the potential to set off symptoms of the condition.
11/13/13 - Scientists at Rutgers and Emory universities have discovered that an organic compound, often emitted by fungi, causes symptoms of Parkinson's disease in fruit flies and may be linked to Parkinson's and other neurodegenerative diseases in humans.
11/12/13 - A pilot study by a multi-disciplinary team of investigators at Georgetown University suggests that a simple dot test could help doctors gauge the extent of dopamine loss in individuals with Parkinson's disease (PD). Their study was presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience.
11/8/13 - Scientists at University of Copenhagen and University of Edinburgh have identified a core set of functionally relevant factors which regulates embryonic stem cells' ability for self-renewal. A key aspect is the protein Oct4 and how it makes stem cells stick together.
11/8/13 - Psychosis is a common non-motor symptom of Parkinson's disease whose pathogenesis remains poorly understood. Parkinson's disease in conjunction with psychosis has been shown to induce injury to extracorticospinal tracts as well as within some cortical areas.
11/7/13 - Physical activity tracking apps on smart phones are a potentially important tool for doctors who want to collect data and create treatment or intervention plans to improve the health of patients who struggle with activity and movement -- such as those with Parkinson's disease.
11/6/13 - Non-motor symptoms, including abnormalities in cognition, mental behaviors, autonomic nerves and sensory perception, have the greatest effect on the quality of in Parkinson's disease patient life. Voxel-based morphometry can be used to quantitatively compare structural differences and func-tional changes of gray matter in subjects.
11/6/13 - Researchers at Chalmers University of Technology in Sweden, together with researchers at the Polish Wroclaw University of Technology, have made a discovery that may lead to the curing of diseases such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease (the so called mad cow disease) through photo therapy.
11/1/13 - Researchers say that a new non-dopaminergic drug called pimavanserin may be the first to offer safe and effective treatment for patients who experience psychotic symptoms associated with Parkinson's disease. This is according to a new study published in The Lancet.
10/30/13 - Newcastle-based medical technology company MANUS Neurodynamica Ltd has developed a revolutionary pen for the early diagnosis of Parkinson's disease. The unique sensory pen technology and software is sensitive to major neurological signs of the disease and has shown compelling results during five years of exploratory trials.
10/30/13 - Scientists at Rutgers University studying the cause of a rare childhood disease that leaves children unable to walk by adolescence say new findings may provide clues to understanding more common neurodegenerative diseases like Alzheimer's and Parkinson's and developing better tools to treat them.
10/28/13 - Using a discovery platform whose components range from yeast cells to human stem cells, Whitehead Institute scientists have identified a novel Parkinson's disease drug target and a compound capable of repairing neurons derived from Parkinson's patients.
10/25/13 - Parkinson's disease continues to puzzle physicians and biologists alike - even though it is well-established that symptoms like muscle tremors, rigidity, and, during the final stages, immobility can all be traced back to the death of a certain type of brain cell called a dopaminergic neuron.
