Symptoms of Parkinson's Disease

In its fully developed form, Parkinson's disease is easy to recognize. However, Parkinson's and its symptoms are often subtle in the beginning and tend to progress slowly. So early symptoms of Parkinson's disease may last a long time before the more classic and obvious symptoms appear.
Often, the first noticeable sign of Parkinson's disease is a tremor. This characteristic symptom often begins on one side of the body, frequently in one hand. It is often more obvious during rest, and improves with activity. It may also affect the arms, legs, feet, jaw, face, eyelids, and tongue. After months or years, the tremor may become present in all limbs and on both sides of the body.
Other common symptoms of Parkinson's disease include:
  • Stiffness in the limbs and trunk
  • Slow movement
