Parkinson's Disease SymptomsThe three key signs of Parkinson's disease are tremor (shaking) at rest, rigidity, and slowness in the initiation of movement (called bradykinesia). Of these features, two are required to make the diagnosis. Postural instability is the fourth key sign, but it happens late in the disease, usually after having PD 8 years or more.
Symptoms are usually progressive in their severity over time. However, not every symptom described may be apparent in each individual PD patient. However, the older the age of initial onset of PD, usually the more rapid development of motor and cognitive decline symptoms. Next Page: Must Read Articles Related to Parkinson Disease
