The tiny particles created by these scientists might also help to overcome some of the drawbacks of current …

Two Exercise Programs Improve Dexterity, Quality of Life: Study

Two different types of rehabilitation-focused exercise programs — activity-based training and strength exercises — improved measures of dexterity and upper limb function in a small clinical trial of people with Parkinson’s disease. The study, “Effect of Activity-Based Training Versus Strengthening Exercises on Upper Extremity Functions in Parkinson’s Patients; A…

UB-312 Vaccine Well Tolerated by Healthy Adults in Ongoing Trial

UB-312, an experimental vaccine targeting aggregated and toxic forms of alpha-synuclein to treat Parkinson’s disease, was generally well tolerated at multiple doses in a clinical trial in healthy adults. Study data also suggest that UB-312 prompted an immune response, as designed, against the alpha-synuclein protein. With two doses now selected…

Spine Implants May Help Clear Up Orthostatic Hypotension

Electrical implants in the spine can clear up feelings of lightheadedness upon standing — the result of a condition called orthostatic hypotension — in people with neurological disorders like Parkinson’s disease, new research shows.
