Researchers Identify Tissue Biomarker for Dementia with Lewy Bodies and Parkinson’s Disease
Accurate diagnosis of Parkinson’s disease, and the related disease “dementia with Lewy bodies,” can be difficult in the early stages of both conditions. While brain biopsies can be more accurate, the risk of complications has been considered too high. New research published in the Journal of Parkinson’s Disease indicates that a biopsy of the submandibular gland can help identify the same pathology that is seen in the brain, providing some of the increased accuracy of brain biopsy, but not the increased risk.

Parkinson’s Disease Funding Analyzer Launched on Journal of Parkinson’s Disease Website
The Journal of Parkinson’s Disease (JPD) is proud to announce the launch of the Parkinson’s Disease Funding Analyzer (PDFA) on the JPD website. It is a free service that is part of a new suite of online features that have been designed to serve the needs of the Parkinson’s disease (PD) research community.

Are Stem-Cell Therapies for Parkinson’s Disease Ready for Clinical Trials?
As stem cell-based therapies are moving rapidly towards clinical trials, treatments for Parkinson’s Disease (PD), an incurable condition, may be on the horizon. A recent announcement of a Phase I/IIa clinical trial involving transplantation of stem cells into the first human subjects has raised hope among patients and sparked discussions in the research community. In a commentary published in the Journal of Parkinson’s Disease, authors propose five key questions that should be addressed as this trial begins.

'Slow thinking' a conversation stopper for people with Parkinson's
Cognitive impairment could affect the conversational ability of people with Parkinson’s more than physical speech problems - according to research from the University of East Anglia (UEA) and the University of Aberdeen.
A new study published today is the first to assess the extent to which a patient’s ability to think quickly forms a barrier to communication – rather than experiencing physical speech problems.

Researchers Identify Biomarker for Early Cognitive Decline in Parkinson’s Disease Patients
Many patients with Parkinson’s Disease (PD) develop mild cognitive impairment (MCI) or dementia. Identifying biomarkers for cognitive impairment could be instrumental in facilitating both early diagnosis of MCI and developing new cognitive-enhancing treatments. New research published in the Journal of Parkinson’s Disease indicates that lower concentrations of α-synuclein in cerebrospinal fluid (CSF) is associated with reduced performance on several cognitive tests.

Researchers Face Potential Danger from Protein Particles in the Lab
Lewy bodies and Lewy neurites are found in the brains of Parkinson’s disease (PD) patients. They consist primarily of fibrils of the protein alpha-synuclein (α-Syn), which self-assembles into fibrils in vitro. If introduced into the human body, these seeds can act as prions and trigger the formation of toxic protein deposits. Because α-Syn fibrils are often used in research, it is important that they are not accidentally transferred to humans or cell cultures. Researchers reporting in the Journal of Parkinson’s Disease describe three cleaning procedures that effectively remove and disassemble these α-synuclein seeds.

Use of Anticholinergic Drugs Does Not Increase Risk for Dementia in Parkinson’s Disease Patients
Recent evidence has shown a greater risk of dementia, in particular Alzheimer’s disease (AD), in individuals using anticholinergic medications regularly. These drugs are widely used by older adults to treat bladder dysfunction, mood, and pain, and many of them are available without prescription. Since these drugs are often used to treat both motor symptoms and non-motor symptoms in patients with Parkinson’s Disease (PD), there is concern for increased risk of dementia. Contrary to expectations, a study in the current issue of the Journal of Parkinson’s Disease determined that the cognitive performance of PD patients taking anticholinergic medications did not differ from those who did not.

Gaucher Disease May Protect Against Parkinson’s Disease-Related Color Visual Impairment
Parkinson’s Disease (PD) patients have a five-fold greater risk of carrying genetic mutations in the β-glucocerebrosidase gene (GBA), which are commonly associated with Gaucher disease (GD). Patients with both PD and GD tend to experience earlier onset of PD and more serious cognitive changes than PD patients without the mutations. A new study published in the Journal of Parkinson’s Disease suggests that GD or the presence of GBA mutations may actually shield patients from deficiency in visual color discrimination, which is a hallmark of PD.

Does Alcohol Consumption Affect the Risk for Parkinson’s Disease?
For many years, researchers have been investigating whether there are any associations between Parkinson’s disease (PD) and lifestyle choices such as smoking and coffee and alcohol consumption. In a review published in the Journal of Parkinson’s Disease, the literature concerning alcohol consumption presents conflicting information.
