Information on Parkinson's disease. Learn about Parkinson's disease treatments, symptoms, new research and medication.
  1. Researchers have discovered a direct link between the protein aggregation in nerve cells that is typical for neurodegenerative diseases, and the regulation of gene expression in Huntington's disease. The results pave the way for the development of new treatment strategies for diseases that involve impairment of the basic mechanism by which the body's cells can break down and recycle their own component parts. This process, called autophagy, is disrupted in for example Huntington's and other neurodegenerative diseases.
  2. The eyes may be a window to the brain for people with early Parkinson's disease. People with the disease gradually lose brain cells that produce dopamine, a substance that helps control movement. Now a new study has found that the thinning of the retina, the lining of nerve cells in the back of the eye, is linked to the loss of such brain cells.
  3. A slate of guidelines to shape the future of Parkinson's biomarker research have been published.
  4. An aquarium fish that senses the Earth's magnetic field as it swims could help unlock how the human brain works and how diseases such as Parkinson's and other neurological disorders function. Scientists have discovered a navigational gene in glass catfish called the electromagnetic-perceptive gene, or EPG, that responds to certain magnetic waves. They've already developed a way to use it to control movement in mice.
  5. Biological markers responsible for extreme exhaustion in patients with cancer have now been linked to fatigue in those with Parkinson's disease, according to new research.
  6. Neuroscientists have uses a Pavlovian model of conditioning to see if turning on a light -- a simple cue -- just before dopamine neurons were activated could motivate action.
  7. Mutations in the gene LRRK2 have been linked to about three percent of Parkinson's disease cases. Researchers have now found evidence that the activity of LRRK2 protein might be affected in many more patients with Parkinson's disease, even when the LRRK2 gene itself is not mutated.
  8. Parkinson's disease, formerly also referred to as shaking palsy, is one of the most frequent disorders affecting movement and the nervous system. Medical researchers have come across a possible cause of the disease - in the patients' immune system.
  9. Parkinson's disease was first described by a British doctor more than 200 years' ago. The exact causes of this neurodegenerative disease are still unknown. Scientists now questioned the previous understanding of this disease.
  10. Researchers say they have developed an experimental drug, similar to compounds used to treat diabetes, that slows the progression of Parkinson's disease itself -- as well as its symptoms -- in mice.
