The U.S. National Institutes of Health (NIH) launched a consortium to support clinical studies designed to better understand the link between the gut and brain in Parkinson’s disease. The Gut-Brain Communication in Parkinson’s Disease Consortium is motivated by the fact that there are compelling data indicating that the gastrointestinal…
Researchers in China have identified three genes — GPX2, CR1, and ZNF556 — with increased activity in people with Parkinson’s disease that could play a role in its development. If validated in future studies, these genes could ultimately serve as disease biomarkers to facilitate Parkinson’s diagnoses. “Our study identifies…
A flexible dose of experimental oral treatment tavapadon significantly lessened motor symptoms in adults with early-stage Parkinson’s disease, according to top-line results from a completed Phase 3 clinical trial. Developer Abbvie expects to present full results of the study, TEMPO-2 (NCT04223193), at a future medical meeting and…
Researchers have developed a chemical tag that can detect and measure protein clumping, which is thought to contribute to neurodegenerative diseases like Parkinson’s, in living cells. The potential diagnostic tool, called TME, readily distinguished living white blood cells derived from Parkinson’s patients over those from healthy individuals, outperforming current…
Early data on recruitment and enrollment from Photopharmics’ Phase 3 clinical trial of its light-based, at-home therapy device for Parkinson’s disease — a novel treatment called Celeste — highlight both the interest in, and feasibility of, fully remote studies done in a patient’s home, according to the company. Such home-based, decentralized…
P2B001, Pharma Two B’s investigational combination therapy of pramipexole and rasagiline, safely and effectively lessens symptoms in people with early-stage Parkinson’s disease, according to pooled data from Phase 2b and Phase 3 clinical trials. The combo treatment was also found to be as effective as titrated extended-release pramipexole…
Parkinson’s disease patients carrying the G2385R mutation in the LRRK2 gene, a known risk factor for the disease, show a slower worsening of tremors and less daytime sleepiness than those idiopathic Parkinson’s, whose disease has no identified cause, a study from China reports. The study also found that…
Axons, nerve cell projections that carry electrical signals from one cell to another, may look more like pearls on a string than the cylindrical tubes they are commonly believed to resemble, according to a study, which demonstrated that interfering with the formation of pearl-like structures impaired the transmission of electric…
A team of South Korean scientists has created technology that can measure brain activity in monkeys without the need for wires or batteries that would interfere with the normal instincts of the animal — an advancement, according to the scientists, that may ultimately aid in research into neurological conditions such…
Neuron-supporting cells called astrocytes produce regular pulses of gamma-aminobutyric acid (GABA), a chemical that suppresses excessive brain activity, that appear to help maintain the body’s circadian rhythms and consistent sleep-wake cycles. That’s according to a study in mice. The findings, if confirmed in humans, may “help us to better understand…
