What is Parkinson’s disease?
Parkinson’s disease is a progressive neurological disorder of the nervous system that affects voluntary movement. Smooth, coordinated muscle movements of the body are controlled by dopamine. It is produced in ‘substantia nigra’.
In Parkinson’s, the cells in the substantia nigra region start to die and hence the dopamine level reduces. When their levels drop below 60-80% symptoms of Parkinson’s begin to appear.
What are the symptoms of Parkinson’s disease?
The symptoms of the disease can be different for everyone. Early symptoms can be mild and can even go unnoticed. Symptoms often begin on one side of the body and usually worsen on that side.
