Study summary

Much of human interaction is based on trust. Aging has been associated with deficits in trust-related decision making, likely further exacerbated in age-associated neurodegenerative disease (Alzheimer's disease/AD), possibly underlying the dramatically growing public health problem of elder fraud. Optimal trust-related decision making and avoiding exploitation require the ability to learn about the trustworthiness of social partners across multiple interactions, but the role that learning plays in determining age deficits in trust decisions is currently unknown.

Aim: Probe the malleability of the underlying neurocircuitry of trust-learning deficits in aging. This study will utilize real-time fMRI neurofeedback to train older adults in brain activity up-regulation toward enhanced trust-related learning in aging and confirm critical mechanisms of experience-dependent social decisions in aging.

Grant R01AG072658 Aim 3: Test the malleability of trust-learning neurocircuitry toward optimized trust-related decision making in aging.

Read the detailed description

This study will apply rtfMRI neurofeedback training as an intervention method, to demonstrate that older adults can be trained in volitional brain activity up-regulation, reducing their trust-learning deficits. The study will comprises several MRI sessions including pre-training, training, and post-training scans.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Able to provide verbal and written
  • Fluent English speaker
  • At least 8th grade education
  • On stable medication regimen

Exclusion criteria

Exclusion Criteria:

  • Pregnancy
  • Magnetic resonance imaging (e.g., certain metallic objects in body, claustrophobia)
  • Current major depression defined as scores >14 on the Beck Depression Inventory-II
  • Impaired scores on the Telephone Interview for Cognitive Status (TICS; cut-off of >30)
  • Current use of medications with significant anticholinergic properties due to potential influence on memory ("memory enhancing"; e.g., Aricept or Namenda)
  • Current use of anticonvulsant, neuroleptic, sedatives, or other medications known to affect cognition
  • Uncorrected visual and hearing impairments
  • Neurologic conditions affecting the brain (e.g., severe stroke, epilepsy, traumatic brain injury with >30-minute loss of consciousness)
  • Impaired scores on a cognitive screening measure, the (MoCA); for older adults the cutoff will be age and education corrected
  • Unstable medical illness (e.g., cancer)
  • Significant cardiovascular conditions (e.g., major heart attack)
  • Will not exclude participants who are taking anti-depressant medications. Use of antidepressants (particularly SSRI's) and anxiolytic medications will be recorded and included in post-hoc analyses
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

MMSE and MoCA

Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Study arms

  • Experimental
    Contingent rtfMRI neurofeedback training

    Contingent rtfMRI neurofeedback training will follow an alternating up-regulation/rest block design with screen-color cues. Visual feedback about real-time brain activity in the ROI will be provided (e.g., via a thermometer bar). During resting blocks, the thermometer bar remains static.

  • Sham comparator
    Non-contingent/sham rtfMRI neurofeedback training

    Non-contingent/sham rtfMRI neurofeedback training will follow an alternating up-regulation/rest block design with screen-color cues. Visual feedback about non-contingent/sham brain activity in the ROI will be provided (e.g., via a thermometer bar). During resting blocks, the thermometer bar remains static.

What researchers measure

Primary outcomes

  1. Neurofeedback Training Success

    Increase in BOLD signal in ROI during up-regulation trials administration of computerized learning tasks, with contrasting groups and conditions

    Time frame: at baseline and after training completion about 1 week later

  2. Behavioral Benefits

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2024 (actual). Primary completion is estimated for Apr 2027, 30 months after the start.

Of 79 non-industry interventional studies with no phase under Neurocognitive Disorders, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 46. This study's planned 30 months is close to that.

Counting every sponsor, half of 82 studies reached it within 32 months; a quarter within 17 and three quarters within 46.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 23, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
