Parkinson's Disease

What Is Parkinson’s Disease?

Parkinson’s Disease (PD) is a neurodegenerative condition that affects the nervous system, resulting in motor symptoms such as tremor, rigidity, bradykinesia (slowness of movement), and postural instability (loss of balance). It is estimated that over 6 million people are affected by the disorder worldwide.

What Causes Parkinson’s Disease?

The causes of Parkinson’s Disease are not yet fully understood. It is believed that the disorder occurs when there is a deficiency in the neurotransmitter dopamine, which is produced by the cells in the brain. The exact cause of dopamine deficiency is unknown, however, it is thought to be caused by genetic and environmental factors.
