Two Studies Examine Diabetes Drugs in PD
Tuesday, August 25, 2015

Two clinical studies investigating a class of type 2 diabetes drugs for Parkinson’s disease (PD) are helping scientists to better understand PD and if there are possible uses for these drugs. The studies respectively found that extended treatment with one specific drug does not improve PD symptoms, but that people who take one in the class of drugs may have a lower risk of PD.

Taiwanese Study Suggests PD Increases Risk for Most Cancers
Monday, August 17, 2015

A new study of a large sample of people living in Taiwan reports that having Parkinson’s disease (PD) increases one’s risk for later developing most types of cancer, underscoring the importance of ethnicity and environmental exposure when computing risks. The results were published online June 18 in JAMA Oncology.

New Deep Brain Stimulation Device Holds Promise for Better Therapy
Wednesday, August 12, 2015

A new technique for delivering deep brain stimulation (DBS) A surgical treatment for Parkinson's disease. A special wire (lead) is inserted into a specific area of the brain responsible for movement. The lead is connected to a pacemaker-like device implanted in the chest region.

Traumatic Brain Injury Late in Life Increases Parkinson’s Risk
Friday, June 5, 2015

People aged 55 and older who were treated in the hospital for traumatic brain injury were 44 percent more likely to develop Parkinson’s disease (PD) over the next six years than those who sustained injuries, but not head injuries, according to research published in the March 28 online edition of Annals of Neurology.

New Guidelines for Treating Orthostatic Hypotension in PD
Tuesday, June 2, 2015

A new study suggests updated diagnosis and treatment guidelines for people with Parkinson’s disease (PD) who experience orthostatic hypotension A drop in blood pressure upon changing position from lying down or sitting to standing; can cause fainting.

Scientists Flip a “Light Switch” to See How Transplanted Dopamine Neurons Work
Wednesday, May 27, 2015

With a technique that uses light to turn cell activity off and on, scientists have shown that neurons transplanted into mice with Parkinsonian symptoms can integrate into the brain and release dopamine A chemical messenger (neurotransmitter) that regulates movement and emotions..

Scientists Identify a New Parkinson’s Disease Gene
Wednesday, May 20, 2015

By studying the genes of a large family in which eight members across two generations were affected by Parkinson’s disease (PD), researchers have identified a new genetic mutation that may cause PD. The results appear in the March edition of The Lancet Neurology.

Parkinson’s Affects Both Low- and High-Contrast Vision
Wednesday, May 20, 2015

A new study confirms that people with Parkinson’s disease (PD), as compared to healthy individuals, experience trouble with certain aspects of vision, including contrast sensitivity (e.g., distinguishing between shades of gray) and using high-contrast vision at a distance. The results appear in the February 17 online edition of the Journal of Parkinson’s Disease.

Depression Linked to Increased Risk of Parkinson’s
Wednesday, May 20, 2015

A study published in the May 20 online edition of Neurology provides new evidence that people with depression A mood disorder whose symptoms can include a persistent sad or empty mood, feelings of hopelessness or pessimism, irritability and loss of interest or pleasure in previously enjoyable activities. are more
