Tau seeds from patients induce progressive supranuclear palsy pathology and symptoms in primates

Grégoire Courtine, Tomislav Milekovic, Flavio Raschella

Progressive supranuclear palsy is a primary tauopathy affecting both neurons and glia and is responsible for both motor and cognitive symptoms. Recently, it has been suggested that progressive supranuclear palsy tauopathy may spread in the brain from cell ...

A method for fast automated assessment of the magnetic resonance parkinsonism index

Bénédicte Marie Maréchal

In patients with parkinsonian syndromes, and particularly during the early stages of the clinical disease, differentiating between idiopathic Parkinson's disease and progressive supranuclear palsy is challenging. Imaging plays an important role in early di ...
