Parkinson’s disease is considered as one of the motor systems disorder. It is the result of the loss of dopamine – producing brain cells. Dopamine is a chemical that is responsible for transmitting signals within the brain. This disease occurs when certain nerve cells or neurons become impaired or damaged which makes the patients lose control of their normal movements.

There are four major symptoms of Parkinson’s disease, and these are as follows:

1. trembling of the hands, legs, jaws and face

2. stiffness of the limbs

3. slowness of movement

4. postural instability

If you notice that this is happening to a loved one or to yourself then go to your physician for a check up. It might be Parkinson’s disease.
