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 Results may not be published yet.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.

Summary

This study uses powerful 7T MRI scanners and visual perception tests to find biological markers for severe mental disorders like major depression, schizophrenia, and bipolar disorder. Researchers will compare brain chemistry and vision in 320 patients and healthy volunteers. The goal is to make diagnosis and treatment monitoring more objective and precise.

What this could mean

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

What this could lead to
If successful, this could lead to more objective diagnostic tools and treatment monitoring for severe mental disorders, reducing reliance on subjective symptom checklists.
What could go wrong
This is an early-stage observational study, not a treatment trial. It may not identify clear biomarkers, and any findings will need years of further validation before clinical use.

Who is studied

Patient Group: Recruited from the Department of Psychiatry at The Second Affiliated Hospital of Zhejiang University School of Medicine, consisting of three subgroups: patients with major depressive disorder (MDD), schizophrenia (SZ), and bipolar disorder (BD), all meeting the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) diagnostic criteria. Healthy Control (HC) Group: Recruited from the general public, with no history of mental disorder diagnosis. All participants are aged 18 to 45 years (inclusive), meet the study's inclusion/exclusion criteria (no severe physical illnesses, no organic brain injury, etc.), and will complete non-invasive assessments (7T MRI scans, visual psychophysical experiments, cognitive tests, and clinical symptom evaluations) as required. The patient group receives standard clinical treatment (no study-induced intervention) during the study period.
