Gene variants may affect length of survival in Parkinson’s patients, new study shows
EMOTIVE (Vienna, Sunday, 26 June 2022) How long someone lives with Parkinson’s disease may be down to specific gene mutations, according to new research presented today at the 8thEuropean Academy of Neurology (EAN) Congress.1 Scientists from four institutes in Paris, including the prestigious Paris Brain Institute at the Sorbonne Université, studied the records of 2,037...
Critical step forward in understanding Parkinson’s disease and how to treat it

Chemical inhibitor blocks final path to cell death in mice with Parkinson’s symptoms
by Johns Hopkins University School of Medicine Graphical abstract. Credit: Cell (2022). DOI: 10.1016/j.cell.2022.04.020 In studies in mice, Johns Hopkins Medicine researchers say they have identified a chemical compound that stops the final events in the pathway linked to the death of brain cells in Parkinson’s disease. Results of the experiments, they say, could advance the development...
Researchers find link between Parkinson’s gene and vocal issues that could lead to earlier diagnosis
UNIVERSITY OF ARIZONA Parkinson’s disease is perhaps best known for its movement-related symptoms, particularly tremors and stiffness. But the disease is also known to hinder vocal production, giving those with Parkinson’s a soft monotonous voice. Those symptoms, research has suggested, often appear much earlier in the disease’s development – sometimes decades before movement-related symptoms. New...
Novel Combo Drug Shows Promise as First-Line Parkinson’s Treatment
Kelli Whitlock Burton April 11, 2022 An experimental drug that combines fixed doses of extended-release (ER) formulations of existing medications can significantly reduce symptoms in patients with untreated early-stage Parkinson’s disease (PD), new research suggests. Results from a phase 3 trial of P2B001, a combination of pramipexole and rasagiline at currently unavailable low doses, showed...
Parkinson’s patient first-ever to receive brain implant that reverses symptoms
Dr Alan Whone, Consultant Neurologist. holding a model of The Picostim™ DBS system. NEUROTECH APRIL 27, 2022 by Steve Fink A British hospital is the first in the world to implant a brain device that reverses the symptoms of Parkinson’s disease. Now, its test patient is gushing over the results and says he’s gotten his...
Newly discovered mechanism points to cause of drug-induced parkinsonism
by Chinese Academy of Sciences Mitochondrial content decreased in dopaminergic neurons and astrocytes of mice treated with FNZ. (A to F) Immunostaining was used to detect mitochondria (TOM20) in the dopaminergic neurons (TH) of mice treated with FNZ for 2 weeks. Representative images of mitochondria in neurite (A) and cell body (D) are shown. Quantification...
Using stimulation of the balance organs in the ear as a Parkinson’s treatment
by Olivia Miller, University of Kent Professor David Wilkinson. Credit: University of Kent Some of the most troubling features of Parkinson’s disease can be reduced by gentle stimulation of the balance organs via the application of electric or thermal currents to nearby parts of the head. This observation, made by Professor David Wilkinson at the...
Probing a Parkinson’s Paradox
Researchers seek to understand why some Parkinson’s patients’ symptoms briefly vanish. In one video, an elderly gentleman who normally can barely walk pedals a bike effortlessly down an Amsterdam street. In another video, a man who typically can’t hold a mug without sloshing the water out of it catches a ball as he jogs across the room and...
