Parkinson’s disease (PD) is one of the most common movement disorders affecting adults and occurs when brain cells that make dopamine, a chemical that helps transmit messages between brain cells involved in coordinating movement, stop working.
In most cases, the cause of PD is unknown. An understanding of the complex genetic, environmental, ageing and other factors that lead to PD emerging in any one person is a focus of many research studies. Because PD can cause tremor, slowness, stiffness, and walking and balance problems (motor symptoms), it is called a “movement disorder.” But “non-motor” symptoms including constipation, depression, sleep problems and memory problems can also be part of Parkinson’s disease.
Parkinson’s disease is a lifelong and progressive disease, which means that symptoms slowly worsen over time.
