Study Overview
Brief Summary
This clinical study is a double-blind, randomized, placebo-controlled trial to investigate the effects of melatonin on the sleep disturbance symptoms of Parkinson's disease patients, symptoms which have a significant impact on the quality of life of these patients.
Detailed Description
After selecting patients who satisfied the inclusion criteria and were not disqualified by the exclusion criteria, through a double-blind procedure the patients are directed to orally take either the investigational drug melatonin or a placebo(allocation ratio 1:1) for 4 weeks, once daily, before going to sleep.
