Faster Progression Found in ‘Body-involvement’ Parkinson’s in Study

People with Parkinson’s disease who show early dysfunction in the nerves controlling heartbeat tend to experience faster disease progression, a new study shows. According to researchers, these results support a new approach differentiating “brain-predominant” Parkinson’s from disease with “body-involvement.” “These findings correspond well to the results of…

Ventus, Novo Nordisk Partner on Anti-inflammatory Medications

Ventus Therapeutics and Novo Nordisk have agreed to work together to develop new anti-inflammatory medicines that may be useful in Parkinson’s disease and other disorders, the companies announced. “This is an important collaboration for Ventus that validates our structural biology capabilities to discover and develop highly differentiated…

CBD Found to Improve Survival in Worm Models of Parkinson’s

Treatment with cannabidiol (CBD) prevented nerve cell death, extended survival, and reduced toxic protein clumps in nematode worm models of Parkinson’s disease, a new study reports. “These findings supported CBD as an anti-parkinsonian drug,” the researchers wrote, adding that “this CBD neuroprotective action might be due to its antioxidative…

Probiotic Supplements Found to Ease Parkinson’s Constipation in Trial

Probiotic supplements were found to ease multiple measures of constipation in people with Parkinson’s disease in a small clinical trial. According to researchers, the use of such supplements also “significantly” improved quality of life for patients with constipation problems. “In this study, multi-strain probiotics were used to treat [Parkinson’s]…

Dopamine Agonists Linked to Poorer Blood Vessel Function

Rates of blood vessel dysfunction are not significantly different in people with Parkinson’s disease compared to the general population, a small study reports. The findings indicate that, among people with Parkinson’s, smoking and the use of treatments called dopamine agonists are associated with poorer blood vessel function. The…

Alpha-synuclein Clumping Seen to Affect Mitochondria Early

Alpha-synuclein aggregation — the toxic clumping of proteins in nerve cells that is a hallmark of Parkinson’s disease — starts on the membranes of mitochondria, the so-called powerhouse of a cell, according to work in cell models. “Our study provides insights into what is happening in the earliest stages…
