Parkinson's Disease - Symptoms
The symptoms by which PD can be identified include:
- Tremor (shaking), usually beginning in the hands. The classic tremor associated with PD is called "pill-rolling tremor." The movement is like rolling a pill between the thumb and forefinger. The movement occurs about three times per second.
- Slowing down of movements. A person may slow down or even stop in the middle of familiar movements, such as walking, eating, or shaving.
- Muscle rigidity (stiffness). A PD patient's movements may be jerky rather than smooth.

- Problems with posture and balance. A person may change the way he or she walks to keep from falling over.
- "Masked face." This condition gets its name from the fact that the patient seems to have no facial expression. He or she may even have a greatly reduced rate of eye blinking.
Parkinson's disease may also be accompanied by one or more other symptoms, including:
- Depression
- Changes in the way a person speaks
- Sleep problems, including restlessness and nightmares
- Emotional changes, including increased fear, irritability, and feelings of insecurity
- Incontinence (loss of bladder control)
- Constipation
- Changes in handwriting
- Dementia (increased problems with mental functions)
