The four initial primary symptoms of Parkinson's are:
- tremor or trembling mostly in the hands, arms, and jaw
- rigidity or stiffness of the limbs and trunk
- slowness of movement (bradykinesia)
- postural instability or impaired balance and coordination.
Early symptoms are subtle and occur gradually.
