Parkinson’s disease is a nervous system disorder that often involves symptoms of dementia.  The tremor exhibited in Parkinson’s disease is one of the most common and most widely recognized symptoms of the disease.  This tremor is not only upsetting to the person with Parkinson’s, but also can interfere with his or her daily activities, including basic hygiene, recreational activities and eating.  Previously a person who wished to correct the tremor to assist in eating would have to wear cumbersome tremor suppression equipment, but new research has led to a device that allows the tremor to happen freely, providing for greater comfort, while cancelling out the movement in the spoon itself to prevent food from being spilled.
Technology like this helps improve the lives of those who have to live with active tremors and allows for a more normal experience in daily life.
