Information on Parkinson's disease. Learn about Parkinson's disease treatments, symptoms, new research and medication.
  1. Parkinson's disease is commonly thought of as a movement disorder, but after years of living with the disease, approximately 25 percent of patients also experience deficits in cognition that impair function. A newly developed research tool may help predict a patient's risk for developing dementia and could enable clinical trials aimed at finding treatments to prevent the cognitive effects of the disease.
  2. Researchers have found the first direct evidence that autoimmunity plays a role in Parkinson's disease, suggesting that immunosuppressants might play a role in treatment.
  3. A potential new mechanism has been identified in both mice and human endocrine cells that populate the small intestines. Inside these cells is a protein called alpha-synuclein, which is known to go awry and lead to damaging clumps in the brains of Parkinson's patients, as well as those with Alzheimer's disease.
  4. Use of statins may speed up the onset of Parkinson's disease symptoms in people who are susceptible to the disease, according to researchers.
  5. Consuming at least three servings of low-fat dairy a day is associated with a greater risk of developing Parkinson's disease compared to consuming less than one serving a day, according to a large study.
  6. A team of researchers is using breakthrough gene-editing technology to develop a new screening tool for Parkinson's disease, a debilitating degenerative disorder of the nervous system. The technology allows scientists in the lab to 'light up' and then monitor a brain protein called alpha-synuclein that has been associated with Parkinson's.
  7. Researchers have identified the precise toxic mechanism at work during an overabundance of the protein alpha-synuclein in neurons—the protein is a key causative agent in the development of Parkinson’s disease.
  8. Most cases of Parkinson's have no known cause, and researchers continue to debate and study possible factors that may contribute to the disease. Research now suggests that a certain strain of influenza virus predisposes mice to developing pathologies that mimic those seen in Parkinson's disease.
  9. Although Parkinson’s disease is often associated with motor symptoms such as stiffness, poor balance and trembling, the first symptoms are often sensory and include a reduced sense of touch and smell. In a study on mice, researchers have now been able to identify neural circuits and mechanisms behind this loss of sensory perception. The study may open avenues to methods of earlier diagnosis.
  10. A new article compares survival rates among patients with synucleinopathies, including Parkinson disease, dementia with Lewy bodies, Parkinson disease dementia and multiple system atrophy with parkinsonism, with individuals in the general population.
