"Montreal Neurological Institute scientists shed light on the mechanism that could be driving the spread of Parkinson’s along neuronal highways.

Scientists at the Montreal Neurological Institute and Hospital -The Neuro, at McGill University and the McGill University Health Centre, have made advances in understanding the process involved in the progression and spread of Parkinson’s disease (PD) within the brain.

The study, published in September issue of eLife, focused on understanding the process that drives the disease’s progression by mapping the distribution and degree of atrophy, characteristic of the disease, in certain brain regions and identify the paths leading the spread from affected to healthy tissue.

“Past studies have failed to consistently demonstrate regional brain atrophy in earlier stages of the disease due to samples of subjects that were too small and to methods that were less sensitive in detecting all aspects of the disease’s impact on the brain. We now have the means to map the disease with greater sensitivity than previously possible,” says Dr. Alain Dagher, senior author of the study.

Pocket-sized device could help Parkinson’s patients regain balance

Pocket-sized device could help Parkinson’s patients regain balance | Social Neuroscience Advances | Scoop.it
A wearable device that stimulates the sense of balance with electric “noise” could help Parkinson’s disease patients, according to Swedish scientists.

Scientists from the University of Gothenburg’s Sahlgrenska Academy have developed a portable pocket-sized vestibular, or balance, stimulation device in a bid to improve the lives of Parkinson’s sufferers.
