Primary Outcome Measures:
  • Motor Function

Secondary Outcome Measures:
  • Cognition
  • Mood
  • Quality of Daily Life

Estimated Enrollment: 360
Study Start Date: September 2005
Study Completion Date: February 2008
Detailed Description:
This study is to focus on the effects of Lingzhi on non-motor symptoms of Parkinson's diseases as the primary outcome and on delaying the disease progression using the delay start design as the secondary outcome measurement. Two dosage groups and one placebo control group with total 360 subjects will be recruited. The treatment is one year.
