Parkinson's disease is a disorder of the nervous system that primarily affects bodily movement. Impairment or death of nerve cells in the brain leads to the development of the condition. The loss of these neurons causes essential neurotransmitter levels to decrease, particularly the production of the neurotransmitter dopamine. This, in turn, leads to abnormal brain activity that affects one's control of muscle movement. Older individuals are the most common group diagnosed with Parkinson's.

1. Tremors

One of the earliest and most widely occurring symptoms of Parkinson's disease is resting tremors. Usually, this begins with the trembling or shaking of one finger. Sometimes the hand or foot on one side of the body experiences tremors or, in rare cases, the face or jaw. The tremors usually begin when the affected body part is relaxed, which is why they are called "resting tremors." Not all tremors are symptomatic of Parkinson's, however.
