Parkinsonâs disease (PD) is a neurological movement disorder that, according to the National Institutes of Health (NIH), affects as many as 500,000 people in the United States. PD starts with the brain cells, called neurons, which control movement. Neurons produce a substance called dopamine. PD sets in when the neurons die and the levels of dopamine in the brain decrease. The lack of dopamine is thought to result in the symptoms that affect the way you move. Early signs of Parkinsonâs disease can be easy to miss sometimes, especially if they occur sporadically.
