Toxic clumps of the protein alpha-synuclein change the way the brain cells most affected by Parkinson’s disease utilize energy, a study shows. Its researchers wanted a clearer understanding of how “key metabolic processes” are affected by the protein’s aggregation, damaging “vulnerable” nerve cells within the brain, they wrote. To…

Mark Denham, PhD, a scientist in Denmark, has been awarded a patent that covers a new way of using stem cells to create cell therapies for Parkinson’s disease. Securing the patent, which provides two decades of intellectual property protection for the technology, is a first step toward establishing a…

Dosing has begun in a Phase 1 clinical trial that is testing GT-02287, an experimental oral medication being developed to treat Parkinson’s disease caused by mutations in the GBA1 gene. The first two participants in the trial have been dosed, according to the therapy’s developer, Gain Therapeutics. “Initiating first-in-human…

In people with Parkinson’s disease, the cerebral cortex of the brain can compensate for disease-related dysfunction in the basal ganglia, the main part of the brain affected by Parkinson’s. Researchers found that patients with milder Parkinson’s symptoms have more compensatory activity in the cerebral cortex, while patients with…

Measuring levels of an enzyme called DOPA decarboxylase (DDC) in the blood or fluid around the brain and spinal cord may help distinguish Parkinson’s disease and related disorders from non-Parkinsonian neurodegenerative diseases, a study reports. “Since the symptoms of various neurodegenerative brain diseases resemble each other, there is a…

When the alpha-synuclein protein is present at high concentrations around cellular membranes, it lifts up rather than lying flat against the membrane, making it more prone to clumping, a study shows. The finding may offer insight into the molecular mechanisms that drive Parkinson’s disease, where toxic clumps of alpha-synuclein…

Dopamine-making neurons — whose loss characterizes Parkinson’s disease — produce thousands of circular RNA molecules that, beyond their normal duties, may play a role in neurodegenerative diseases, a study reports. “Circular RNA has long been cast aside as junk, but we believe it has an important role in programming…

The parkin enzyme — whose loss is a known genetic risk factor of Parkinson’s disease — not only helps to regulate healthy activity of energy-generating mitochondria, but also plays critical roles in nerve cell communication, according to a study using patient-derived neurons. Particularly, parkin loss resulted in defective recycling…

A platform developed by NeuraLight that uses machine learning to measure eye movements may help track the progression of Parkinson’s disease, a study shows. “NeuraLight’s technology enables us to assess the patient’s neurological status in a sensitive and objective way. The results of this study mark an important…

Researchers have developed a new tool, called RETFound, to analyze images of the eyes using artificial intelligence (AI). The scientists showed this tool can be used to accurately identify eye diseases, and it could even identify other disorders including heart failure and Parkinson’s disease. “This is another big step…
