Symptoms of Parkinson's disease often manifest as:
A resting tremor
Stiffness or rigidity
A slow shuffling gait
Slowness of movement (bradykinesia)
A reduction in automatic movements, such as blinking, swallowing, arm swing and facial expression.
The cause of Parkinson's disease is unknown. However, several factors are thought to play a role in disease development. These include rural living, exposure to pesticides or toxins, drinking well water and genetics. Advanced age is also a risk factor for development of Parkinson's disease. The average age of onset is 60, but the disease starts at a younger age in some cases.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
