What this study is
This study is investigating how something functions in the body, rather than testing a treatment directly.
This study is not organised into the usual phase numbers — that is common for device, behavioural, and diagnostic research.

Who receives what
There are 5 groups in this study.
Groups A, B, C and D receive high definition transcranial direct current stimulation (HD-tDCS).
Registry label: A: left DLPFC stimulation · B: right DLPFC stimulation · C: left IPL stimulation · D: VLPFC-PCC stimulation
Group E, the shamSham procedureA procedure made to feel like the real one, without the active step.Read more → group, receives high definition transcranial direct current stimulation (HD-tDCS).

How the study is run
Which group you would be placed in is decided by chance, like a coin flip — not by you and not by your doctor.
One group of people involved — usually the participants — is not told which treatment is which.

Common questions
Answered from this trial’s registry record. Where the record doesn’t say, these answers say so rather than filling the gap.
Am I eligible for this trial?
Only the trial siteTrial siteA hospital or clinic where a study is actually run.Read more → can decide whether someone can take part. Concord cannot make that determination, and neither can any tool that has not examined you.
