Under-recognized Nonmotor Symptoms of Parkinson's Disease

Originally presented on March 12, 2013
Led by K. Ray Chaudhuri, D.Sc., M.D.

Are your "invisible symptoms" your most problematic?  Immense advances have been made in the treatment of motor symptoms of Parkinson's.  Yet our understanding of the nonmotor symptoms first described by James Parkinson in the 19th century has lagged behind, with advances in the past ten years just beginning to expand our knowledge.  

At the same time, these symptoms are often the most challenging for people living with Parkinson's, their care partners and their doctors.  If treated effectively, nonmotor symptoms - ­particularly lesser known symptoms such as fatigue, vision problems, sweating and crying ­- can be the most important determinant in improving quality of life in Parkinson's.  

Find out more about what you can do to take charge of these symptoms, by joining PDF and Professor Chaudhuri for a one-hour PD ExpertBriefing discussing the topic.

Goals for Participants:

  • Understand the nonmotor symptoms of PD and why it is important to look at them holistically.
  • Understand how people with Parkinson's disease can recognize and talk to their doctors about nonmotor symptoms, and how doctors and nurses can assess them in the clinic.
  • Differentiate which nonmotor symptoms can be induced by medications and which are due directly to Parkinson's disease.
  • Become aware of the treatment options available for nonmotor symptoms, and potential new treatments under exploration in clinical trials.
