What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tests whether a mild electrical brain stimulation technique called tDCS can improve cognitive flexibility in people with orthorexia nervosa — an extreme fixation on healthy eating. Researchers will compare brain wave patterns and task performance before and after real or fake stimulation in 48 adults. The goal is to understand the brain activity behind orthorexia, not to cure it.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
transcranial direct current stimulation (tDCS)
What this could lead to
If it works, this could point toward a non-drug brain stimulation method to help people with orthorexia think more flexibly about food.
What could go wrong
This is a small, early-stage study (48 people) that measures brain activity, not symptoms. It may not lead to a treatment, and tDCS effects can be subtle or inconsistent.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 48 people

The number the study aims to enrol. It can still change while the study runs.

Started

Nov 2025

Expected to finish

Jul 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 40 years

Sex

Anyone

Healthy volunteers

You do not need to have the condition being studied to take part.
