A new study has found that Parkinson’s disease is associated with changes in the visual system, a feature that can be detected earlier than the most common symptoms of the disease, suggesting it could be used as a biomarker to follow disease progression. The study “Visual System Involvement in Patients with…

Xadago (safinamide) is now available in the U.S. as an add-on treatment for patients with Parkinson’s disease currently taking levodopa/carbidopa to control their “off” episodes, according to an announcement from Newron Pharmaceuticals and US WordMeds.

Parkinson’s disease may in part be driven by autoimmune processes, according to researchers who discovered that certain immune cells react to alpha-synuclein — a protein that accumulates in the brains of Parkinson’s patients. The findings, published in the journal Nature, raise the possibility that immunotherapy could be used to…

An enzyme called asparagine endopeptidase may participate in the development of Parkinson’s disease by cleaving alpha-synuclein protein into toxic fragments, according to new research. The study, “Asparagine endopeptidase cleaves α-synuclein and mediates pathologic activities in Parkinson’s disease,” was published in the journal Nature Structural and Molecular Biology. The…

Treatment with Prana Biotechnology’s investigational drug PBT434 showed potential in preventing neuronal death in a mouse model of Parkinson’s disease, according to a new study. Results showed that PBT434 blocked the formation of alpha-synuclein aggregates, a hallmark of Parkinson’s, and normalized iron levels in the brain, thereby protecting neurons…

A recent study has discovered a link between frequent or chronic occurrences of gastrointestinal (GI) tract infections and the development of Parkinson’s disease (PD). The study’s authors have shown for the first time that the nerve cell protein alpha-synuclein (αS), produced by the enteric nervous system, is a key mediator of intestinal inflammation. The enteric nervous system (ENS)…
