Parkinson’s disease is a chronic disorder of the nervous system leading to shaking, stiffness and trouble with walking, balancing and coordinating. It is caused after nerve cells in the brain fail to produce enough of a substance called dopamine, which is believed to result in the symptoms that affect the bodily movement.

Initial symptoms of Parkinson’s are difficult to spot. However, symptoms of the neurodegenerative disorder begin gradually and get worse over time. Apart from affecting the brain, Parkinson’s also affects the entire body.

According to National Institutes of Health, about 60,000 people in the U.S. are diagnosed with Parkinson’s every year. In some cases, Parkinson’s is genetic but in most instances the disorder is not hereditary. Health experts have said that exposure to chemicals in the environment may also play an important role.
