People with persistent smell deficits are more likely to develop brain imaging abnormalities suggestive of Parkinson’s disease, or be diagnosed with the disease, than those whose deficits return to normal on a subsequent smell test, according to data from a Phase 2 study. Deficits in two consecutive smell tests,…

Scientists have shed new light on the interaction of toxic apha-synuclein clumps — a hallmark of Parkinson’s disease — with microglia, the brain’s immune cells. This interaction was found to be mediated by RAGE, a protein at the surface of microglia, which promoted the release of inflammatory molecules from…

Servier is set to launch a Phase 1 clinical trial in healthy volunteers to investigate an LRRK2 inhibitor, developed in collaboration with Oncodesign, as a treatment for Parkinson’s disease. The trial, to start before the end of the year, follows the clearance of the Phase 1 clinical trial…

Older age at onset, a faster rate of disease progression, and severe cognitive impairment are key factors in poorer survival rates for people with Parkinson’s disease, a study that followed patients in northern China for 10 years found. Fatigue may also be an indicator of poorer survival, while physical exercise…
