The Therapeutic Effect of Transcranial Direct Current Stimulation on

Status Terminated

Clinical Trial Summary

Parkinson's disease (PD) is one of the most common neurological diseases manifested by movement disturbance. The concomitant psychiatric symptoms, especially depression, are often observed and have also great impact on patients' quality of life. The treatment of depressive symptoms in PD with antidepressants as the majority remains variable and inefficient, which complicates the disease prognosis. Transcranial direct current stimulation (tDCS) is a non-invasive brain modulation technique and has been demonstrated to improve psychiatric diseases such as major depression. In this study the investigators will assess the combined effects of tDCS on sertraline for the treatment of depression in PD. Ten sessions of tDCS in two weeks will be applied and the follow-up evaluation will continue bi-weekly for one month after completing all sessions. The efficacy of tDCS vs sertraline will be compared and evaluated with behavioral and cognitive outcome. In addition, the investigators will evaluate if the baseline dopaminergic activity in brain could predict the treatment outcome by using SPECT imaging. The investigators aim to establish the therapeutic parameters and safety criteria of tDCS as an add-on or alternative therapy, and further enhance the overall clinical efficacy in the treatment of depression in PD.

Clinical Trial Description

Study design This study is a factorial randomized, placebo-control trial, including 2 groups: 'sertraline only' (sertraline + sham tDCS), and 'combined treatment' (sertraline + active tDCS). It is planned to recruit 20 subjects for each group, which results in all together 40 participants. Patients will take 12 tDCS sessions (30min for each session): first 10 consecutive sessions for two weeks (Monday to Friday), and then 2 follow-up sessions scheduled 2 and 4 weeks after the consecutive treatment. Both pharmacological and tDCS intervention will be started simultaneously on the first day of the treatment. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
