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 Results may not be published yet.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 brain imaging (fMRI) to investigate why people with schizophrenia or depression often have trouble with memory and managing emotions. Researchers will scan the brains of 90 adults aged 18-60 while they perform tasks and at rest. The goal is to better understand the brain mechanisms behind these cognitive problems, which can persist even after other symptoms improve.

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 study could reveal how the brain causes thinking and memory problems in schizophrenia and depression, pointing toward new targets for future treatments.
What could go wrong
This is an observational brain imaging study, not a treatment trial. It will not directly improve symptoms, and the findings may not lead to new therapies for years, if at all.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * age 18-60 years * current Intelligence Quotient (IQ) \> 70 as measured by the Wechsler Abbreviated Scale of Intelligence (WASI) * the ability to read and speak fluent English * a diagnosis of schizophrenia, schizoaffective or major depression disorder * stable medication for more than one month Exclusion Criteria: * significant neurological or other medical disorders that may produce cognitive impairment * a recent history of substance abuse or dependence (within the past 3 months) * any magnetic resonance imaging (MRI) contraindications (e.g. metallic head implant, history of seizure, pacemaker) * decisional incapacity requiring a guardian * taking medications that are rated as Anticholinergic Burden (ACB) Score 3 (severe) or taking benzodiazepines on a daily basis * Finally, participants could not be severely symptomatic at the time of study enrolment to ensure that they could understand and complete all study assessments. This criterion was defined as a score ≤34 on the Montgomery-Åsberg Depression Rating Scale (MADRS; Montgomery \& Åsberg, 1979) for the MDD group and a score ≤95 on the Positive and Negative Syndrome Scale (PANSS; Kay et al., 1987) for the SZ group.
