Information on Parkinson's disease. Learn about Parkinson's disease treatments, symptoms, new research and medication.
  1. Detailed brain cell analysis has helped researchers uncover new mechanisms thought to underlie Parkinson's disease.
  2. Researchers have uncovered why people with a hereditary form of Parkinson's disease suffer from sleep disturbances. The molecular mechanisms uncovered in fruit flies and human stem cells also point to candidate targets for the development of new treatments.
  3. A new study shows that people who take drugs that suppress the immune system are less likely to develop Parkinson's disease, which is characterized by difficulty with movement.
  4. Deep brain stimulation has been used to treat Parkinson's disease symptoms for 25 years, but limitations have led researchers to look for ways to improve the technique. This study describes the first fully implanted DBS system that uses feedback from the brain itself to fine-tune its signaling.
  5. Previous studies have found an association between two commonly used agrochemicals (paraquat and maneb) and Parkinson's disease. Now a professor has determined that low-level exposure to the pesticides disrupts cells in a way that mimics the effects of mutations known to cause Parkinson's disease. Adding the effects of the chemicals to a predisposition for Parkinson's disease drastically increases the risk of disease onset.
  6. Doctors may be able to modify or slow down the progress of the neurological condition Parkinson's disease in the future by spotting signs of it in patients with inflammatory bowel disease (IBD), suggest a new study.
  7. Research sheds light on how the human brain rapidly forms new memories, providing insights into potential new treatments for memory disorders. A new study examined neurons that produce dopamine, a compound that acts as a transmitter for nerve impulses. It found that these dopamine neurons play a critical role in the formation of episodic memory, which allows people to remember such things as where they parked the car in the morning and what they had for dinner last night.
  8. Researchers have found that elevated levels of certain types of lipids (fat molecules) in the brain may be an early sign of Parkinson's disease (PD). This finding could have significant implications for identifying patients who may be at risk for developing PD and for the early treatment of the disease.
  9. The rabies virus wreaks havoc on the brain, triggering psychosis and death. To get where it needs to go, the virus must first trick the nervous system and cross the blood brain barrier -- a process that makes it of interest in drug design. Now, scientists report a way to exploit the rabies virus machinery to deliver a Parkinson's disease medication directly to the brain.
  10. People who have been diagnosed with a mild concussion, or mild traumatic brain injury, may have a 56 percent increased risk of developing Parkinson's disease.
