So you"ve heard of Parkinson"s disease (PD), but can you recognize the symptoms? There are four main signs of the disease:
- Tremors (trembling)
- Rigidity (muscle stiffness)
- Postural instability (impaired balance and coordination)
- Bradykinesia (slowed movement)
You may want to get familiar with the signs--experts estimate that at least 500,000 people in the United States suffer from PD, and the financial burden may total more than $6 billion each year. And because older people are more at risk, researchers believe the disease"s impact will continue to grow.
