Symptoms

The diagnosis of PD depends upon the presence of one or more of the four most common motor symptoms of the disease, which are: resting tremor, bradykinesia, rigidity and postural instability.

In addition, there are other secondary and nonmotor symptoms that affect many people and are increasingly recognized by doctors as important to treating Parkinson’s.

Each person with Parkinson's will experience these symptoms differently. For example, many people experience tremor as their primary symptom, while others may not have tremors, but may have problems with balance. Also, for some people the disease progresses quickly, and in others it does not.
