The selective loss of dopamine-producing nerve cells in one side of the brain of mice, to mimic Parkinson’s disease, impacted the length of movement sequences on the opposite side of the body, but not the same side, a study shows. The study’s researchers discovered two distinct populations of these…

An observational clinical trial in Canada that’s investigating the role of the small intestinal microbiome — the population of natural microorganisms living in the gastrointestinal tract — in Parkinson’s disease is now recruiting participants. Its researchers specifically aim to determine if Parkinson’s patients carry a unique microbial and metabolic…

A first participant has been dosed in Arvinas’ first-in-human Phase 1 trial testing ARV-102, its oral therapy candidate for neurodegenerative conditions, including Parkinson’s disease and progressive supranuclear palsy, or PSP, an atypical parkinsonian disorder. The Phase 1 trial — now enrolling healthy volunteers at the Centre for Human Drug…

Computer scientists at the University of North Carolina at Chapel Hill have developed software and an augmented reality (AR) headset that allows clinicians to analyze movement in people with Parkinson’s disease to help guide their physical therapy. Clinicians can also use their own AR headsets to immerse themselves in…

Suppressing astrocytes’ release of the pro-inflammatory molecule interleukin (IL)-6 reduced the loss of dopaminergic neurons, the nerve cells that are progressively lost in Parkinson’s disease, a new study reports. In Parkinson’s, astrocytes, the star-shaped cells that provide physical support for neurons in the brain, secrete high levels of IL-6…

Using machine learning to analyze speech from speakers of different languages could help distinguish between Parkinson’s disease and essential tremor, two neurological disorders that can cause similar symptoms. That’s according to the study, “Automatic speech-based assessment to discriminate Parkinson’s disease from essential tremor with a…

A natural chemical modification — called O-GlcNAc — that occurs in specific building blocks of the alpha-synuclein protein can lessen its capacity to form toxic amyloid fibrils, a hallmark of Parkinson’s disease, a study shows. “Taken together, we believe that these results have important implications for … the exploitation…

Mutations in the PRKN gene, a common cause of early-onset Parkinson’s disease, were tied directly to low activity of the gene, a study reports. Because gene activity was measured by standard methods using cells in the bloodstream, the findings may support developing an “easily accessible screening test for PRKN mutations,”…

Parkinson’s disease patients who experience tremor are invited to complete an online survey aimed at assessing the difficulties due to this common disease symptom, with an ultimate goal of promoting more effective treatments. The survey, called the “Burden of Tremor in Parkinson’s Disease,” is a collaboration…

Treatment with CNM-Au8, an investigational gold nanocrystal suspension therapy, boosted energy production in the brains of people with Parkinson’s disease and multiple sclerosis (MS) in a pair of Phase 2 trials, indicating the medication works as intended. Findings also suggest functional gains in treated Parkinson’s patients. However,…
