About this study
Official title: Study of tDCS Intervention on Motivational Anhedonia of Major Depressive Disorder
Study of tDCS intervention on motivational anhedonia of Major Depressive Disorder
Read the detailed description
All patients underwent a medical evaluation that included physical examination and routine laboratory studies before and after transcranial direct current stimulation (tDCS) treatment. Patients were randomly allocated to real group , sham group or control group. A threshold of 3 points on the Hamilton Depression scale has been specified by the National Institute for Health and Care Excellence to determine a clinically meaningful difference between active pharmacotherapy and placebo. We plan to enroll minimum total sample size of 37 participants in real, sham or control group respectively according to the Power and Sample Size program. The decision to enroll a patient was always made prior to randomization. The tDCS administrators had access to the randomization list. They had minimal contact with the patients, and no role in assessing depression. Each patient would be treated for continuous 14 days by tDCS in real and sham group. The control group was evaluated by clinical symptom scale, behavioral evaluation before and after 14 days.
Before the tDCS treatment, depression symptom of each participant was assessed by the Hamilton Depression Scale and the Beck Depression Self-Rating Scale. The anhedonia severity was evaluated by The Temporal Experience of Pleasure Scale, the Self-Report Apathy Evaluation Scale, Dimensional Anhedonia Rating Scale, the Motivation and Pleasure Scale.The neuroimaging data was collected using event-related potentials during monetary incentive delay task. After the last treatment, the same scales and neuroimaging scan were used again to assess the treatment effect of the tDCS and the underlying brain mechanism. Each participant was interviewed in detail about the adverse event of the tDCS intervention during the past 14 days.Every participant should take part in the study in voluntary and sign an informed consent form before the study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
transcranial direct current stimulation with real currentDevice
transcranial direct current stimulation with real current is a noninvasive technique to activate and modify the activity of the neurons
transcranial direct current stimulation with sham currentDevice
transcranial direct current stimulation with sham current is a placebo
| Study group | Role | What they receive |
|---|---|---|
| Real Stimulation | Active comparator | The Real Stimulation of tDCS lasted 20 mins.Behavior and ERPs dataset should be acquired before the first tDCS session and after the last tDCS session. Receives: Device: transcranial direct current stimulation with real current |
| Sham Stimulation | Sham comparator | The Sham Stimulation of tDCS lasted 20 minutes with no current. In particular, the current went up for the first 30 seconds and went down for the last 30 seconds.Behavior and ERPs dataset should be acquired before the first tDCS session and after the last tDCS session. Receives: Device: transcranial direct current stimulation with sham current |
| Control | No intervention | Behavior and ERPs dataset should be acquired before and after 14 days. |
