- Almost two-thirds of Parkinson's patients experience a slight tremor as an initial symptom. This tremor can happen on one side of the body, either in the hand or foot, although sometimes it occurs in the jaw or face.
- Muscle stiffness may also occur and may lead to a decreased mobility and range of motion. A mask-like facial appearance may result from rigidity of facial muscles.
- Difficulty standing upright and coordinating body movements may lead to an inability to turn sharply or make abrupt movements.
- Bradykinesia means "slow movement." Parkinson's sufferers may be unable to initiate basic body movements or may perform normal movements very slowly.
- Speech may be affected due to loss of muscle control, and words may be slurred or spoken very softly.
