Analyses that estimate the length of a person’s vocal tract, which involves controlling muscles used in speech, could help to identify Parkinson’s disease, according to a new study. “The standard clinical method for classifying parkinsonian voice is by perceptual evaluation, which however is subjective,” the researchers wrote. “Computerized voice analysis…
Small-scale, or microstructural, brain alterations observed on the MRIs of people with Parkinson’s disease were associated with worse bimanual coordination, a type of complex movement, a study found. “[D]istinct changes in microstructure cause an impediment of structures involved in attention, working memory, executive function, motor planning, motor control, and…
Researchers have proposed a set of voice exercise games to help speech quality in people with Parkinson’s disease, which licensed speech therapists found to be a generally feasible, promising approach. If adopted in speech therapy routines, the games could motivate patients to practice more often at the home so…
People with Parkinson’s disease appear to have a gut microbiome — the population of microorganisms living in the intestines — that is shifted toward a pro-inflammatory state, a small study suggests. Looking particularly at a pro-inflammatory gut bacterial metabolite called trimethylamine (TMA), its researchers found significantly higher…
Inbrija, an approved treatment for “off” episodes of Parkinson’s disease, has now been launched in Germany. The medication is being sold in Germany by Esteve Pharmaceuticals under an agreement with its developer Acorda Therapeutics. In exchange for supply of the product, Acorda will receive a significant…
The healthcare technology company Koneksa and Northwestern University plan to begin recruiting patients in the third quarter of this year for a study aimed at measuring the severity of vocal abnormalities that can occur in Parkinson’s disease. The clinical trial, which is expected to be completed in 2024, will…
Two European pharma companies have teamed up to create a technology platform that will help people with Parkinson’s disease find the best time to take their medication and make personalized adjustments to their treatment schedules. Gerresheimer AG is partnering with Finnish MedTech start-up Adamant Health Oy on new…
A new method for turning specific human stem cells, called pluripotent stem cells, into neurons that can produce dopamine — the signaling molecule, essential for controlling movement, that is missing in patients with Parkinson’s disease — has now been developed by researchers in the U.S. “Scientists have been trying…
A first study in patients of an intranasal-delivered therapy for Parkinson’s disease is now complete, and early findings support the treatment being safe and leading to improvements in motor function, Zhittya Genesis Medical, the therapy’s developer, announced. Zhittya is offering a first look at the trial data via a…
The buildup of alpha-synuclein in cells and brain tissue in Parkinson’s disease patients is linked to the disruption of processes involved in degrading RNA, the template used for protein production, a study has found. The findings uncover a new biological role for the alpha-synuclein protein, its researchers said. “Our…
