Brief Summary:
Parkinson's disease (PD) is a second common neurodegenerative disease. More than 6 million individuals worldwide have Parkinson disease. No disease-modifying pharmacologic treatments are available. Current medical treatment is symptomatic, focused on improvement in motor (eg, tremor, rigidity, bradykinesia) and nonmotor (eg, constipation, cognition, mood, sleep) signs and symptoms. Accumulating evidence suggests the important role for inflammation and oxidative stress in the pathogenesis of PD. Sulforaphane extracted from broccoli sprout is an agent with potent anti-oxidant and anti-inflammatory activity. Previous studies suggested sulforaphane is useful in dopaminergic neuron survival. In this study, the investigator attempts to evaluate the efficacy and safety of sulforaphane in PD patients.

Condition or disease Intervention/treatment Phase
Parkinson Disease Drug: Sulforaphane Drug: Placebo Phase 2

Detailed Description:
The study will recruit 100 PD patients, and then these patients will be randomized to sulforaphane group or placebo group (50 patients per arm) for 24 weeks clinic trial. Participants will receive 24 weeks of either sulforaphane or placebo per day, in addition to the existing treatment. Baseline assessments include demographics, a comprehensive medical history, anthropometric measurements (weight and height), physical examination, and lab work. The motor symptoms and cognitive function will be assessed by the Unified Parkinson's Disease Rating Scale (UPDRS) and MATRICS Consensus Cognitive Battery #MCCB#, respectively, at baseline, week 12 and week 24. The cranial MRI is examined at baseline and repeated at week 24. The primary outcomes will be the cognitive function improvement. Secondary outcomes include motor symptoms, biological data, MRI, safety and tolerability. During the study period, safety index including blood routine, liver and kidney function and adverse reactions report will be recorded.

Arm Intervention/treatment
Experimental: sulforaphane
The goal of the study is to investigate whether adding sulforaphane will benefit cognitive function in individuals who have PD.
Drug: Sulforaphane
Sulforaphane is a compound that can be extracted from broccoli, Brussel sprouts, cabbage, and other cruciferous plants.

Placebo Comparator: placebo
The purpose of including placebo is to judge if the outcome is related to the study medication rather than other reasons.
Drug: Placebo

Primary Outcome Measures :
  1. Cognitive improvement assessed using the MATRICS Consensus Cognitive Battery (MCCB) composite score [ Time Frame: 24 weeks ]
    The investigators will use the MATRICS Consensus Cognitive Battery (MCCB) Composite score as primary cognitive outcome measure.The MCCB total score is about 50 in healthy participants, the higher the score, the better the cognition performance.

  2. Change of clinical symptoms by UPDRS [ Time Frame: 24 weeks ]
    The change of UPDRS(Unified Parkinson Disease Rating Scale),ranging from 0-199, higher scores mean a worse outcome.
