Stiffness and changes in balance may put you at increased risk for injury from falls. In severe and late stages of the disease, you may become immobile and require constant nursing care. The early symptoms of Parkinson's disease often are mild and may go unnoticed. As the disease progresses, tremors increase and posture becomes stooped, pitched forward, resulting in a shuffling and unsteady gait. Joint and muscle stiffness increase.
Movements become slower.
It becomes more difficult to change direction and to start and stop movements. Salivation and drooling may increase. Blinking of the eyes decreases, resulting in a fixed stare. The face may have a fixed, mask-like expression. You should make an appointment to see your health care provider, even if symptoms are mild.
