But in addition to so-called motor symptoms such as slowness of movement,tremor and stiffness, most people develop other health problems related to Parkinson's. These symptoms are diverse but are collectively known as non-motor symptoms.

Researchers at a Parkinson’s Foundation Center of Excellence have found that a brain MRI (magnetic resonance imaging) that uses a special protocol can track changes that occur as Parkinson’s disease (PD) progresses. This biomarker could be used in clinical trials, as an objective way to monitor whether the therapies being tested are effective. The study appears in the August 2017 issue of Brain.

Welders exposed to fumes containing low levels of the metal manganese had a high rate of Parkinson-like symptoms, which progressed with increasing cumulative exposure to the metal, according to research published in the December 28 online edition of Neurology. The results make a case for better worker protection. They also help scientists understand the underlying mechanisms by which exposure to substances in the environment may contribute to Parkinson’s disease (PD).

A new study finds that cognitive impairment is a frequent and rapidly progressing symptom of Parkinson’s disease (PD). About half of the participants who had PD for an average of five years and had normal cognition at the beginning of the study developed mild cognitive impairment (MCI) within six years – about 11 years after PD diagnosis. Those few who developed MCI progressed to dementia within five more years. The results appear in the September 11 online edition of Neurology.
